0–9

1031 exchange: A tax-deferral move for investment real estate: sell one property and roll the proceeds into another like-kind investment property through a qualified intermediary, deferring the capital gains tax. Strict clocks apply: identify the replacement within 45 days of the sale and close within 180 days. It covers investment property, not personal homes.Full definition & example →Rental property calculator →Capital gains tax calculator →
1099 form: A family of IRS forms reporting income earned outside a regular paycheck, such as freelance pay (1099-NEC), interest (1099-INT), and investment sales (1099-B). If you receive 1099 income, taxes are usually not withheld for you, so you may need to make quarterly estimated payments.Full definition & example →
1099-K: An IRS information form that payment apps, online marketplaces, and card processors send to people who received business payments through them, reporting the gross amount processed for the year. The reporting threshold is set by law and has changed several times, so whether you receive one depends on current rules, but the income is taxable whether or not a form arrives.Full definition & example →W-2 vs 1099 →Quarterly tax calculator →
1099-NEC: The IRS form a business uses to report nonemployee compensation: payments to independent contractors, freelancers, and other self-employed workers who are not on payroll. The business files one for each contractor paid above a small annual threshold and sends the contractor a copy by the end of January.Full definition & example →Self-employment tax calculator →Quarterly tax calculator →
4% rule: A retirement planning guideline: withdrawing 4% of a diversified portfolio in the first year, then adjusting that amount for inflation, has historically survived essentially every 30-year retirement in U.S. market data. It implies a savings target of about 25 times annual spending.Full definition & example →The 4% rule explained →FIRE calculator →
401(k): An employer-sponsored retirement account funded straight from payroll, with contribution limits the IRS adjusts each year. Contributions are pre-tax (traditional) or after-tax (Roth 401(k)), growth is untaxed while invested, and many employers match part of what you put in.Full definition & example →Retirement accounts guide →
401(k) loan: A loan you take from your own 401(k) balance, if the plan allows it, and repay with interest through payroll deductions, usually over up to five years. The interest goes back into your account, but the borrowed money is out of the market while you repay it, and leaving the job can make the whole balance due quickly.Full definition & example →401(k) calculator →
403(b): The 401(k) equivalent offered by public schools, universities, churches, and many nonprofits. The mechanics, tax treatment, and limits closely mirror a 401(k).Full definition & example →
50/30/20 rule: A simple budget framework that splits take-home pay into 50% needs, 30% wants, and 20% savings and extra debt payments. Popular as a starting point because three buckets are easy to maintain.Full definition & example →50/30/20 calculator →Full guide →
529 plan: A state-sponsored education savings account. Money grows tax-free and withdrawals are tax-free when used for qualified education expenses; many states add a tax deduction or credit for contributions.Full definition & example →

A

ACH transfer (Automated Clearing House): An electronic money movement between U.S. bank accounts over the Automated Clearing House network: direct deposits, bill payments, and bank-to-bank transfers. Standard ACH settles in one to three business days, with same-day options growing. Transfers are typically free or nearly free, unlike wires.Full definition & example →
Adjustable-rate mortgage (ARM): A mortgage whose rate is fixed for an intro period (commonly 5, 7, or 10 years) and then adjusts periodically with the market, within caps. The intro rate usually undercuts a 30-year fixed; the risk arrives at the first adjustment.Full definition & example →
Adjusted gross income (AGI): Your total income minus specific adjustments such as traditional IRA or HSA contributions and student loan interest. Many tax credits, deductions, and account eligibility rules phase out based on AGI or its close cousin, modified AGI.Full definition & example →
After-tax contribution: Retirement plan money contributed from pay that has already been taxed, separate from pre-tax and Roth contributions. In plans that allow it, after-tax dollars sit in their own 401(k) bucket: the contributions come back tax-free, but the earnings are taxed on withdrawal unless converted to Roth.Full definition & example →401(k) calculator →
Alimony: Court-ordered or agreed payments from one former spouse to the other after a divorce or separation, also called spousal support or maintenance. The amount and duration depend on state law and the couple's finances. Under federal rules, alimony from agreements signed after 2018 is neither deductible for the payer nor taxable income for the recipient; older agreements may follow the opposite treatment.Full definition & example →Debt-to-income calculator →
Amortization: The schedule by which a loan is paid off in equal installments. Early payments are mostly interest and barely touch the balance; the mix shifts toward principal over time, which is why extra payments early in a mortgage save the most.Full definition & example →
Annual fee: A yearly charge some credit cards levy just for holding the card. Fee cards usually offer richer rewards or perks; the fee is only worth paying if the value you actually use exceeds it.Full definition & example →
Annual percentage rate (APR): The yearly cost of borrowing, including interest and certain fees, expressed as a percentage. Use APR to compare loans and credit cards; the higher the APR, the faster a balance grows against you.Full definition & example →Debt payoff guide →
Annual percentage yield (APY): What money actually earns in a year once compounding is included. Use APY to compare savings accounts and CDs; it is the honest version of an interest rate.Full definition & example →HYSA calculator →
Annuity: An insurance contract that converts a lump sum into a stream of payments, often guaranteed for life. Simple immediate annuities buy predictable income; complex variable and indexed versions layer fees and surrender charges that deserve heavy scrutiny.Full definition & example →
Appraisal: A licensed appraiser's professional estimate of a property's market value, usually ordered by the lender before approving a mortgage or refinance. The loan is sized against the appraised value, not the offer price.Full definition & example →Closing cost calculator →
Assessed value: The value a local government assigns your property for calculating property taxes. It is set by the assessor's office, often lags the market, and in many places is a set fraction of market value.Full definition & example →Property tax calculator →
Asset: Anything you own that has monetary value: cash, investment and retirement balances, crypto, real estate, and vehicles. Assets minus liabilities equals net worth.Full definition & example →Net worth calculator →
Asset allocation: How a portfolio is divided among stocks, bonds, and cash. Allocation sets most of your risk and expected return; a common pattern is heavy in stocks while young, shifting toward bonds as the goal approaches.Full definition & example →Investing guide →
Asset location: Deciding which types of investments to hold in which types of accounts (taxable, tax-deferred, or Roth) to minimize the tax drag on the whole portfolio. It is separate from asset allocation, which decides how much of each investment you own overall.Full definition & example →Start investing guide →
Assets under management (AUM) fee: An advisory fee charged as a percentage of the money a firm manages for you, deducted from the account each quarter or year rather than billed separately. It is the most common way financial advisors and robo-advisors are paid, and it rises automatically as the account grows.Full definition & example →Investment fee calculator →
Authorized user: Someone added to another person's credit card who can spend on the account but has no legal obligation to pay it. The account's history often appears on the authorized user's credit report, which can help build credit.Full definition & example →Credit utilization calculator →

B

Backdoor Roth IRA: A two-step route into a Roth IRA for people whose income is too high to contribute directly: contribute to a traditional IRA without deducting it, then convert that money to Roth. Direct Roth contributions are limited by income; conversions are not.Full definition & example →Roth IRA calculator →
Balance transfer: Moving credit card debt to a new card offering a 0% introductory APR, typically for a 3-5% fee. It buys time to pay the balance down interest-free, but only helps if the balance actually reaches zero before the promotional period ends.Full definition & example →
Balloon payment: A large lump-sum payment due at the end of a loan whose regular payments were too small to pay off the balance. The monthly payments are set as if the loan ran for a long term, but the loan actually matures much sooner, leaving the remaining principal due all at once.Full definition & example →Amortization calculator →
Bankruptcy (Chapter 13): A federal repayment-plan bankruptcy: you keep your property and pay creditors what your budget allows over three to five years, after which most remaining unsecured debt is discharged. Often used to stop a foreclosure and catch up on a mortgage or car loan.Full definition & example →Debt payoff guide →
Bankruptcy (Chapter 7): A federal legal process that discharges most unsecured debts after a court-supervised review, giving a fresh start when debts have become unpayable. Exemptions typically protect essentials such as retirement accounts, basic household goods, and often some home and car equity. Most cases finish in a few months.Full definition & example →Debt payoff guide →
Barista FIRE: A partial version of FIRE where investments cover most, but not all, living costs, and a low-stress or part-time job bridges the gap, often chosen for the health insurance as much as the paycheck.Full definition & example →FIRE calculator →
Basis point: One hundredth of a percentage point: 100 basis points equal 1.00%. Finance uses the unit to discuss rates and fees precisely, so a move from 6.25% to 6.75% is 50 basis points.Full definition & example →Investment fee calculator →
Bear market: A sustained market decline, conventionally a drop of 20% or more from a recent high. Bear markets arrive regularly, feel terrible while they last, and in broad U.S. market history have always eventually given way to new highs.Full definition & example →Investing guide →
Beneficiary: The person or entity named to receive an account or insurance payout when you die. Beneficiary designations on retirement accounts and life insurance override your will, so audit them after every major life event.Full definition & example →Protection guide →
Billing cycle: The roughly monthly period a credit card statement covers, usually 28-31 days. When the cycle closes, the statement balance and due date are set; pay the statement balance in full by the due date and purchases typically accrue no interest.Full definition & example →Credit card payoff calculator →
Blue-chip stock: Stock in a large, established, financially sturdy company with a long record, often decades of profits and dividends. The name comes from the highest-value poker chip.Full definition & example →Dividend calculator →
Bond: A loan you make to a government or company in exchange for regular interest and your money back at maturity. Bonds are steadier than stocks and act as the shock absorber in a diversified portfolio.Full definition & example →
Bond ladder: A portfolio of individual bonds or CDs with staggered maturity dates, so that a portion matures every year or so. As each rung matures, the cash is either spent or reinvested in a new long rung at whatever rate is available then.Full definition & example →CD calculator →
Bridge loan: A short-term loan that lets a homeowner buy a new home before the current one sells, using the equity in the existing house as collateral. It typically carries a higher rate and more fees than a mortgage and is repaid in a lump sum when the old home closes.Full definition & example →HELOC calculator →
Brokerage account: A taxable investment account with no contribution limits or withdrawal rules. It is where investing continues after tax-advantaged accounts are maxed, and where money for pre-retirement goals can grow.Full definition & example →
Budget: A plan that assigns your income to spending, saving, and debt before the month happens. The methods that last run mostly on automation rather than willpower.Full definition & example →Budgeting guide →
Bull market: A sustained period of rising prices, commonly dated from a 20% rise off a market low. Bull markets historically run for years and deliver the bulk of long-term returns.Full definition & example →Investment calculator →
Buy now, pay later (BNPL): Point-of-sale installment plans that split a purchase into a few payments, commonly four interest-free installments over about six weeks, with longer interest-bearing plans for larger purchases. Late payments can trigger fees, and plans increasingly appear on credit reports.Full definition & example →

C

Capital gain: The profit from selling an asset for more than you paid. In the U.S., gains on assets held longer than a year are taxed at lower long-term rates than short-term gains, which are taxed like ordinary income.Full definition & example →
Capitalized interest: Unpaid interest that gets added to a loan's principal balance, so that future interest is charged on it too. It is common on student loans when a deferment, forbearance, or grace period ends and the accrued interest has not been paid.Full definition & example →Student loan calculator →
Cash advance: Borrowing cash against a credit card at an ATM or bank counter. Cash advances usually carry an upfront fee, a higher APR than purchases, and no grace period: interest starts the moment the cash is dispensed.Full definition & example →Credit card payoff calculator →
Cash flow: Money in minus money out over a period: income minus all spending. Positive cash flow builds net worth; negative cash flow drains savings or grows debt, whatever the income level.Full definition & example →Budget calculator →
Cash stuffing: The cash-envelope method's modern name: withdraw spending money in cash and divide it into labeled envelopes, one per category. When an envelope is empty, that category is finished until next payday.Full definition & example →Budget calculator →
Cash-out refinance: Replacing your mortgage with a larger one and taking the difference in cash, converting home equity into money in hand. The new loan restarts the clock with its own rate, term, and closing costs.Full definition & example →Refinance calculator →HELOC calculator →
Catch-up contribution: Extra retirement contributions the tax code allows once you reach age 50 (age 55 for HSAs), on top of the standard annual limits. The exact extra amounts are set by the IRS and adjust over time.Full definition & example →Retirement calculator →
Certificate of deposit (CD): A bank deposit locked for a fixed term at a fixed rate, usually paying more than a regular savings account, with a penalty for early withdrawal. A ladder of CDs with staggered maturities balances yield and access.Full definition & example →
Charge-off: A lender declaring a debt unlikely to be collected, typically after about 180 days of missed credit card payments, and writing it off its books. The debt does not disappear: you still owe it, and it is often sold to a collection agency.Full definition & example →
Checking account: The transactional bank account your paycheck lands in and bills flow out of. It should hold about a month of spending; larger balances belong somewhere that pays interest.Full definition & example →
Child support: Payments a parent makes to help cover a child's living costs after a separation or divorce, set by a court or state formula based on income, custody time, and the number of children. It is not taxable income to the recipient and not deductible by the payer.Full definition & example →Budget calculator →
Child tax credit: A federal tax credit for each qualifying child, generally under age 17, that reduces your tax bill dollar for dollar rather than merely reducing taxable income. The credit amount, income phase-outs, and refundable portion are set by Congress and change over time.Full definition & example →
Cliff vesting: A vesting schedule where you earn none of an employer's contributions or equity grants until a set date, then all of it at once. It contrasts with graded vesting, which releases ownership in yearly slices. One-year cliffs are standard for startup stock options, and 401(k) plans may use a cliff of up to three years for employer contributions.Full definition & example →
Closing costs: The fees due at a real estate closing beyond the down payment: lender origination, appraisal, title insurance, prepaid taxes and insurance, and recording fees. Budget roughly 2 to 5 percent of the loan amount.Full definition & example →
Co-borrower: A second person who applies for a loan alongside the primary borrower, shares ownership of what it buys, and is equally responsible for repaying it. Unlike a cosigner, who only guarantees the debt, a co-borrower's name goes on the title and the loan reports on both credit files.Full definition & example →Mortgage affordability calculator →
Coast FIRE: The point where your current investments, left untouched, will compound into a full retirement portfolio by traditional retirement age. After that, work only has to cover today's living costs.Full definition & example →Coast FIRE calculator →Coast FIRE guide →
COBRA continuation coverage: A federal right to keep your employer health plan after leaving a job, usually for up to 18 months, by paying the full premium yourself plus up to a 2% administrative fee. The coverage is identical; the employer subsidy is what disappears.Full definition & example →
Coinsurance: The percentage of a medical bill you keep paying after meeting your deductible, until you hit the plan's out-of-pocket maximum. An 80/20 plan means insurance pays 80% and you pay 20% in that middle zone.Full definition & example →HSA calculator →
Collections account: A debt handed to or bought by a collection agency after the original lender gave up, appearing as its own entry on your credit report. It can remain for up to seven years from the original missed payment.Full definition & example →Debt payoff guide →
Community property: A marital property system, used by a minority of states, in which most assets and debts acquired during a marriage belong equally to both spouses regardless of whose name is on the account or who earned the money. Property owned before the marriage, plus gifts and inheritances, usually stays separate.Full definition & example →Money as a couple guide →
Compound interest: Interest earned on both your original money and the interest it already earned. It is the engine of long-term investing, and of credit card debt when it runs against you.Full definition & example →Compound interest calculator →
Conforming loan: A mortgage that fits the size limits set annually by federal regulators and the underwriting standards of the government-sponsored enterprises that buy most U.S. home loans. Loans above the size limit are jumbo loans, with their own pricing and requirements.Full definition & example →Mortgage calculator →
Consumer Price Index (CPI): The government's main inflation gauge: it tracks the price of a broad basket of goods and services (housing, food, transportation, medical care) over time. The percentage change in CPI is what headlines call the inflation rate.Full definition & example →Inflation calculator →
Contingency (real estate offer): A condition written into a purchase offer that lets the buyer back out and keep their earnest money if it is not met. Common contingencies cover financing, the home inspection, the appraisal, and the sale of the buyer's current home.Full definition & example →First-time home buyer checklist →
Conventional loan: A mortgage not insured by a government program (such as FHA, VA, or USDA loans). Most are also conforming loans. With less than 20% down, conventional loans typically require private mortgage insurance until you build enough equity.Full definition & example →PMI calculator →Down payment calculator →
Corporate bond: A loan you make to a company in exchange for scheduled interest payments and your money back at maturity. Rating agencies grade issuers: investment-grade bonds pay less because default is unlikely; high-yield (junk) bonds pay more because it is not.Full definition & example →
Cosigner: Someone who signs a loan alongside the primary borrower and becomes fully, legally responsible for the entire debt. The loan and every payment, good or bad, appear on both credit reports.Full definition & example →Student loan calculator →
Cost basis: What you originally paid for an investment, including reinvested dividends. Sale price minus cost basis is your taxable capital gain or loss.Full definition & example →
Cost-of-living adjustment (COLA): An automatic increase to a payment, such as Social Security benefits, a pension, or wages under some contracts, meant to keep pace with inflation. Social Security's COLA is set each year from a government consumer price index and applied to every beneficiary's check.Full definition & example →Inflation calculator →Social Security calculator →
Credit counseling: Guidance from certified counselors, usually at nonprofit agencies, covering budgets, debt options, and credit. Initial sessions are typically free or low cost, and the agency may propose a debt management plan for unsecured debts.Full definition & example →Debt payoff calculator →Debt payoff guide →
Credit freeze: A free lock on your credit file at each bureau that blocks new accounts from being opened in your name. It stops most identity-theft loans cold and can be lifted temporarily online when you apply for credit yourself.Full definition & example →
Credit limit: The maximum balance a lender allows on a credit card or line of credit. Spending relative to the limit is your utilization, a major score factor, and issuers can raise or cut limits based on behavior.Full definition & example →Credit utilization calculator →
Credit mix: The variety of account types on your credit report: revolving credit (cards, lines of credit) versus installment loans (auto, student, mortgage). Scoring models give a modest bonus for handling both kinds well, roughly a tenth of a classic score's weight.Full definition & example →
Credit report: Your borrowing history as recorded by the three bureaus (Equifax, Experian, TransUnion): accounts, balances, payment history, and applications. You can check all three free at annualcreditreport.com; errors are common and worth disputing.Full definition & example →
Credit score: A 300-850 number summarizing your credit risk, used to price loans and sometimes screen apartment and insurance applications. Payment history and utilization drive about two-thirds of it.Full definition & example →Building credit while paying debt →
Credit union: A member-owned, nonprofit financial cooperative offering the same core products as a bank: checking, savings, loans, and cards. Deposits are federally insured by the NCUA up to the same limits as FDIC coverage at banks.Full definition & example →
Credit utilization: Your credit card balances as a percentage of your credit limits. Keeping it under 30%, ideally under 10%, is one of the fastest levers on your credit score.Full definition & example →
Crypto exchange: An online platform for buying, selling, and holding cryptocurrency, converting between dollars and digital assets for a trading fee. Assets left on an exchange sit in the platform's custody, and balances are not FDIC-insured the way bank deposits are.Full definition & example →Crypto profit calculator →
Cryptocurrency: Digital assets recorded on decentralized blockchain networks rather than issued by a government or bank. Prices are set purely by supply and demand, which makes the asset class dramatically more volatile than stocks or bonds.Full definition & example →Crypto profit calculator →
Custodial account (UGMA/UTMA): An investment account an adult manages for a minor, who takes full control at the age of majority (18 to 21 depending on the state). Unlike a 529, the money can fund anything for the child's benefit, but it is irrevocably the child's.Full definition & example →
Custodial Roth IRA: A Roth IRA opened by a parent or guardian for a minor who has earned income, such as pay from a summer job or babysitting. The adult manages the account until the child reaches the age of majority in their state; contributions cannot exceed what the child actually earned, within the normal IRA limit.Full definition & example →Roth IRA calculator →Compound interest calculator →

D

Debt avalanche: A payoff method that puts every spare dollar toward the highest-APR debt first while paying minimums on the rest. It is the mathematically cheapest route out of debt.Full definition & example →Debt payoff calculator →
Debt consolidation: Combining several debts into one new loan or balance-transfer card, ideally at a lower rate with a single payment. It restructures debt; it does not reduce it.Full definition & example →Debt payoff calculator →
Debt management plan (DMP): A structured payoff program arranged by a nonprofit credit counseling agency: you make one monthly payment to the agency, which pays your unsecured creditors, who often agree to reduced interest rates and waived fees. Plans typically run three to five years, and enrolled cards are closed.Full definition & example →Debt payoff calculator →
Debt settlement: Negotiating with a creditor to accept less than the full balance as final payment, usually on debt that is already deep in delinquency. Done directly or through for-profit settlement companies that charge substantial fees.Full definition & example →Debt payoff calculator →
Debt snowball: A payoff method that targets the smallest balance first for quick wins, then rolls each freed-up payment into the next debt. Slightly more interest than the avalanche, but the momentum keeps many people going.Full definition & example →Snowball vs. avalanche →
Debt-to-income ratio (DTI): Monthly debt payments divided by gross monthly income. Mortgage lenders generally like a total DTI at or below 36%, with roughly 43% as a common ceiling for qualified mortgages.Full definition & example →DTI calculator →DTI guide →
Deductible: What you pay out of pocket before insurance starts covering claims. Higher deductibles mean lower premiums; the trade only works if your emergency fund can actually cover the deductible.Full definition & example →
Deed: The legal document that transfers ownership of real estate from one party to another and is recorded with the county. It names the owners and how they hold title. It is distinct from the mortgage, which is the loan secured by the property, and from the title, which is the legal right of ownership the deed conveys.Full definition & example →Closing cost calculator →
Deferment: A temporary pause on student loan payments granted for specific reasons, such as being enrolled in school at least half-time, unemployment, or economic hardship. On subsidized federal loans the government pays the interest during deferment; on unsubsidized and private loans interest keeps accruing.Full definition & example →Student loan calculator →
Deficiency balance: The amount you still owe after a lender repossesses or forecloses on collateral and sells it for less than the loan balance, plus repossession and sale costs. In many states the lender can sue for a deficiency judgment and collect it like any other debt.Full definition & example →Debt payoff guide →
Defined benefit plan: A traditional pension: the employer promises a specific retirement income, typically based on salary and years of service, and bears the investment risk of funding it. Increasingly rare in the private sector, still common in government jobs.Full definition & example →Annuity calculator →
Defined contribution plan: A retirement plan where the contributions are defined but the outcome is not: you (and often your employer) put money into an individual account, you choose the investments, and the final balance depends on markets. 401(k) and 403(b) plans are the standard examples.Full definition & example →401(k) calculator →
Dependent care flexible spending account (FSA): An employer benefit that lets you pay for eligible care with pre-tax payroll dollars: daycare, preschool, after-school programs, summer day camp, or adult day care that lets you (and a spouse, if married) work. Funds are use-it-or-lose-it within the plan year, and the IRS caps annual contributions.Full definition & example →Paycheck calculator →
Depreciation: The decline in an asset's value over time from age, wear, and obsolescence, and, in tax terms, the deduction that lets a business or landlord write off the cost of a long-lived asset gradually over its useful life instead of all at once. A car losing value in the driveway and a rental property producing a paper loss on a tax return are the same word used two ways.Full definition & example →Rental property calculator →Net worth calculator →
Direct deposit: Your paycheck or government benefit sent electronically into your bank account through the ACH network, arriving faster and more reliably than a paper check. Most employers let you split the deposit across multiple accounts.Full definition & example →Paycheck calculator →
Disability insurance: Insurance that replaces part of your income, commonly 40-70%, if illness or injury keeps you from working. Short-term policies cover weeks to months; long-term policies can pay until recovery or retirement age.Full definition & example →Life insurance calculator →
Discretionary income: What remains of your income after taxes and essential obligations: housing, utilities, groceries, insurance, minimum debt payments. It funds wants, extra savings, and faster debt payoff. Federal student loan programs use their own formal definition based on income above a poverty-line multiple.Full definition & example →Budget calculator →
Diversification: Spreading money across many investments so no single failure can sink you. Owning thousands of companies through an index fund is diversification working at full strength.Full definition & example →
Dividend: A share of profits a company pays its stockholders, usually quarterly. Reinvested dividends are a large, quiet part of long-term stock returns.Full definition & example →
Dividend reinvestment plan (DRIP): An arrangement that automatically uses each dividend to buy more shares (including fractions) of the same investment instead of paying out cash. Most brokerage accounts offer it free with a checkbox.Full definition & example →Dividend calculator →
Dividend yield: A stock or fund's annual dividend divided by its price, expressed as a percentage. A $75 stock paying $3 a year yields 4%. Yield moves inversely with price: a falling price raises the yield even when nothing improved.Full definition & example →Dividend calculator →
Dollar-cost averaging: Investing a fixed amount on a fixed schedule regardless of market conditions. You automatically buy more shares when prices are low and remove timing decisions entirely.Full definition & example →Investing guide →
Down payment: The cash paid upfront when buying a home or car, with the rest borrowed. On homes, 20% down avoids private mortgage insurance, though many first-time buyers put down far less.Full definition & example →Savings goal calculator →
Duration (bonds): A measure of how sensitive a bond or bond fund's price is to changes in interest rates, expressed in years. Roughly, a bond with a duration of 5 loses about 5% of its price if rates rise one percentage point and gains about 5% if rates fall by the same amount. Longer maturities and lower coupons mean higher duration.Full definition & example →Start investing guide →

E

Early withdrawal penalty: An extra 10% federal tax on money taken from a traditional IRA, 401(k), or similar retirement account before age 59½, charged on top of the regular income tax owed on the withdrawal. Exceptions exist for disability, certain medical costs, a first-home purchase from an IRA, and other listed situations. The phrase also describes the interest a bank keeps when you cash out a CD before it matures.Full definition & example →401(k) calculator →
Earned income tax credit (EITC): A refundable federal tax credit for workers with low to moderate earnings, sized by income, filing status, and number of qualifying children. Refundable means it can exceed the tax you owe: the difference arrives as a refund. The IRS recalculates the income ranges and credit amounts every year.Full definition & example →
Earnest money: A deposit, commonly 1-3% of the purchase price, that a homebuyer submits with an offer to show they are serious. It sits in an escrow account and is credited toward the down payment and closing costs at closing. If the buyer backs out for a reason the contract does not cover, the seller can keep it.Full definition & example →Down payment calculator →Closing cost calculator →
Effective tax rate: The share of your total income actually paid in tax: total tax divided by total income. It is always lower than your marginal rate under the progressive system, because earlier dollars are taxed in lower brackets and some income is shielded by deductions.Full definition & example →Paycheck calculator →
Emergency fund: Cash reserved for genuine surprises: job loss, medical bills, urgent repairs. The standard target is 3-6 months of essential expenses kept in a high-yield savings account, separate from daily spending.Full definition & example →Emergency fund calculator →Emergency fund guide →
Employer Identification Number (EIN): A nine-digit number the IRS assigns to a business, trust, or estate for tax purposes, the business equivalent of a Social Security number. Sole proprietors can operate under their own SSN, but an EIN is required to hire employees, open most business bank accounts, and form a corporation or partnership. It is free to obtain directly from the IRS.Full definition & example →Stoia for freelancers →
Employer match: Money your employer adds to your 401(k) based on what you contribute, commonly 50-100% of the first 3-6% of salary. It is an instant, guaranteed return; contributing below the full match leaves pay unclaimed.Full definition & example →
Envelope budgeting: A budgeting method where income is divided into labeled envelopes (groceries, gas, fun) and each category can only spend what its envelope holds. The modern version uses app categories; the cash version is back in fashion as cash stuffing.Full definition & example →Zero-based budgeting guide →
Equity: Ownership value. In a home, it is the market value minus the mortgage balance; in investing, equities are stocks, meaning ownership stakes in companies.Full definition & example →
Escrow: An account your mortgage servicer maintains to pay property taxes and homeowners insurance, funded through your monthly payment. When taxes or premiums rise, the escrow portion of the payment rises too.Full definition & example →
Estate tax: A federal tax on transferring wealth at death, owed only on the portion of an estate above a very high federal exemption. The vast majority of estates owe nothing. A minority of states levy their own estate or inheritance taxes, often with lower thresholds.Full definition & example →
Estimated taxes (quarterly taxes): Tax payments freelancers and other untaxed earners send the IRS four times a year, since no employer withholds for them. Generally required if you will owe more than $1,000 at filing.Full definition & example →Stoia for freelancers →
Exchange-traded fund (ETF): A fund that trades on an exchange like a stock. Most popular ETFs are index funds in ETF form: broad, cheap, and tax-efficient.Full definition & example →
Executor: The person named in a will to settle an estate: gather and value assets, notify institutions, pay debts and final taxes, and distribute what remains to the heirs. The role usually runs through the probate court and can take months to a few years.Full definition & example →
Expense ratio: The annual fee a fund charges, as a percentage of your balance. Good index funds charge 0.02-0.10%; typical actively managed funds charge closer to 1%, a difference that compounds into a six-figure gap over a career.Full definition & example →

F

FAFSA: The Free Application for Federal Student Aid, the form students and families file each year to qualify for federal grants, work-study, and federal student loans. Colleges and many states also use it to award their own need-based aid. It asks for income and asset information from the student and, for dependent students, the parents.Full definition & example →College savings calculator →
FDIC insurance: Federal insurance covering bank deposits up to $250,000 per depositor, per bank, per ownership category, if the bank fails. Credit unions carry the equivalent NCUA coverage. Investment losses are not covered; only bank failure is.Full definition & example →
Federal funds rate: The interest rate banks charge each other for overnight loans, steered by the Federal Reserve as its main policy lever. When the Fed moves the target range, rates across the economy follow: credit cards and HELOCs almost immediately, savings yields quickly, and mortgage rates loosely.Full definition & example →
FHA loan: A mortgage insured by the Federal Housing Administration, designed for buyers with smaller down payments or thinner credit. Down payments start around 3.5% and credit requirements are more forgiving than on conventional loans, in exchange for mandatory mortgage insurance premiums (MIP).Full definition & example →Down payment calculator →
FICA (Social Security and Medicare taxes): The payroll taxes that fund Social Security and Medicare, withheld from every paycheck: 6.2% for Social Security (up to an annual wage cap) plus 1.45% for Medicare, 7.65% total. Your employer pays a matching 7.65% on top; self-employed people pay both halves as self-employment tax.Full definition & example →Paycheck calculator →Self-employment tax calculator →
FICO score: The most widely used credit scoring model. The recipe: payment history 35%, amounts owed 30%, length of history 15%, new credit 10%, and credit mix 10%.Full definition & example →
Fiduciary: An advisor legally required to act in your best interest, not just to recommend suitable products. If you hire financial help, ask directly whether they are a fiduciary at all times and how they are paid.Full definition & example →
FIRE (Financial Independence, Retire Early): A movement built on high savings rates and index investing, aiming for a portfolio of roughly 25 times annual spending so work becomes optional decades early. Variants include Lean, Fat, Coast, and Barista FIRE.Full definition & example →The FIRE movement →FIRE calculator →
Fixed expenses: Costs that stay the same every month and are committed in advance: rent or mortgage, insurance premiums, loan payments, subscriptions. They contrast with variable expenses like groceries and gas, which flex with behavior.Full definition & example →Budget calculator →
Fixed-rate mortgage: A home loan whose interest rate is locked for the entire term, so the principal-and-interest payment never changes. The 30-year fixed is the standard American mortgage; 15-year and 20-year versions carry higher payments but far less total interest.Full definition & example →Mortgage calculator →Refinance calculator →
Flexible spending account (FSA): An employer-sponsored account that lets you pay medical costs (or dependent care, in a separate version) with pre-tax dollars. You pick an annual election during open enrollment, the money comes out of each paycheck, and unspent funds are forfeited at year-end unless the plan offers a small carryover or grace period.Full definition & example →
Forbearance: A lender's agreement to let you pause or reduce loan payments temporarily during a hardship, without treating the missed payments as defaults. Interest usually continues to accrue on all loan types during forbearance, and the missed amounts must be made up afterward through a lump sum, a repayment plan, or by adding them to the end of the loan.Full definition & example →Debt payoff guide →
Foreclosure: The legal process a lender uses to take and sell a home after the borrower stops paying the mortgage. Timelines vary by state from a few months to years. The foreclosure stays on the credit report for seven years and usually blocks a new mortgage for several.Full definition & example →
Future value: What a sum of money will grow to by a future date at an assumed rate of return. It is the compound interest question asked forward: present amount, rate, and time in, ending amount out.Full definition & example →Compound interest calculator →Investment calculator →

G

Garnishment: A legal order requiring an employer or bank to divert part of your wages or account balance to a creditor. It typically follows a court judgment, though tax debts, federal student loans, and child support can garnish without one. Federal law caps what most creditors can take, generally up to a quarter of disposable pay, with different rules for support and taxes.Full definition & example →
Gift tax: A federal tax on large lifetime gifts, owed by the giver, not the recipient. Each year you can give any number of people up to an annual exclusion amount with no paperwork; gifts above it must be reported but usually just reduce your lifetime exemption, which is shared with the estate tax and very high. Actual tax is rarely owed.Full definition & example →
Glide path: The schedule by which a target-date fund shifts its mix from mostly stocks toward bonds and cash as the target retirement year approaches. A to-retirement glide path reaches its most conservative mix at the target year; a through-retirement glide path keeps shifting for years afterward, on the theory that the money must last decades past the date.Full definition & example →Start investing guide →Retirement calculator →
Grace period: The window between a credit card statement closing and the due date, during which paying the full statement balance avoids all interest. Carry a balance past it and interest applies to new purchases immediately.Full definition & example →
Gross income: Pay before taxes and deductions. Salaries are quoted gross, but budgets should be built on net (take-home) income, which is often 25-35% smaller.Full definition & example →

H

Hard inquiry: The credit check that happens when you apply for a loan or card. Each one can trim a few points from your score for a while; rate-shopping for the same loan type within a short window typically counts as one inquiry.Full definition & example →
Hardship withdrawal: A 401(k) or 403(b) distribution a plan may allow, while you are still employed, for an immediate and heavy financial need such as medical bills, avoiding eviction or foreclosure, funeral costs, tuition, or repairing casualty damage to a home. The amount is capped at what the need requires, the money cannot be repaid to the plan, and the withdrawal is taxed as income, with the 10% early-withdrawal penalty on top if you are under 59½ and no exception applies.Full definition & example →401(k) calculator →Emergency fund calculator →
Health savings account (HSA): A triple tax-advantaged account available with a high-deductible health plan: deductible contributions, untaxed growth, and tax-free withdrawals for qualified medical costs. After 65, non-medical withdrawals are simply taxed like a traditional IRA.Full definition & example →Retirement accounts guide →
High-deductible health plan (HDHP): A health plan that trades a lower monthly premium for a deductible above IRS-defined minimums, meaning you pay more out of pocket before coverage kicks in. It is the only plan type that allows contributions to a health savings account (HSA).Full definition & example →HSA calculator →
High-yield savings account (HYSA): An FDIC-insured savings account, usually at an online bank, paying many times the national-average rate. The standard home for emergency funds and short-term goals.Full definition & example →HYSA calculator →
Home equity: The portion of your home you actually own: market value minus everything owed against it. It grows three ways, paying down the mortgage, price appreciation, and improvements, and it can be borrowed against through a HELOC, home equity loan, or cash-out refinance.Full definition & example →HELOC calculator →
Home equity line of credit (HELOC): A revolving credit line secured by your home equity. Rates are lower than unsecured debt because the house is collateral, which is exactly the risk: default and the lender can foreclose.Full definition & example →
Home office deduction: A tax deduction for self-employed people who use part of their home regularly and exclusively for business. You can deduct a flat rate per square foot up to a cap (the simplified method) or the business-use share of actual costs like rent, utilities, and insurance. W-2 employees working from home do not qualify.Full definition & example →Self-employment tax calculator →Quarterly tax calculator →
Homeowners insurance: Insurance covering the home's structure, your belongings, and your liability if someone is injured on the property, plus living costs if a covered event makes the home unlivable. Lenders require it, and most owners pay it monthly through escrow. Floods and earthquakes are excluded and need separate policies.Full definition & example →

I

Income-driven repayment (IDR): A category of federal student loan repayment plans that set the monthly payment as a share of the borrower's discretionary income rather than by the loan balance, recalculated each year from income and family size. After a set number of years of qualifying payments, any remaining balance is forgiven. The specific plans, formulas, and terms are set by the Department of Education and change over time.Full definition & example →Student loan calculator →Debt payoff guide →
Index fund: A fund that passively holds every security in a market index, like the S&P 500 or the total U.S. market, at very low cost. Over long periods, index funds outperform the large majority of actively managed funds.Full definition & example →Investing guide →
Individual retirement account (IRA): A retirement account you open yourself at any brokerage, independent of any employer. Traditional contributions may be tax-deductible; Roth contributions are after-tax with tax-free growth. Annual limits are well below 401(k) limits.Full definition & example →
Inflation: The gradual rise in prices that erodes what a dollar buys. At 3% per year, purchasing power drops by about a quarter in a decade, which is why long-term money needs to grow, not sit.Full definition & example →Inflation calculator →
Inheritance tax: A state tax paid by the person who receives an inheritance, calculated on the value received and the heir's relationship to the deceased. Only a small number of states impose one, spouses are generally exempt, and children and other close relatives typically pay less than distant relatives or unrelated heirs. There is no federal inheritance tax; the federal levy on large estates is the estate tax, which the estate pays before anything is distributed.Full definition & example →Protect your progress guide →What happens to debt when you die →
Installment loan: A loan for a fixed amount repaid in equal scheduled payments over a set term: mortgages, auto loans, student loans, and personal loans. Each payment covers that period's interest plus some principal on an amortization schedule, and the loan ends on a known date. The opposite structure is revolving credit, like cards, where the balance and payment float.Full definition & example →Personal loan calculator →Amortization calculator →
Interest: The price of money: what borrowers pay lenders. You earn it on savings and bonds and pay it on cards, loans, and mortgages.Full definition & example →
Introductory APR: A promotional interest rate, often 0%, that a credit card applies to purchases or balance transfers for a set number of months before the regular APR begins. Any balance left when the window closes accrues interest at the full rate going forward. It is different from deferred interest offers, common on store cards, which charge interest retroactively from day one if any balance remains.Full definition & example →Balance transfer calculator →
Irrevocable trust: A trust that, once funded, generally cannot be changed or undone by the person who created it. The grantor gives up ownership and control of the assets, which is exactly why they can be excluded from the grantor's taxable estate and, in many cases, shielded from the grantor's future creditors.Full definition & example →Protect your progress guide →
Itemized deduction: Listing specific deductible expenses on your return, mainly mortgage interest, state and local taxes, charitable gifts, and large medical costs, instead of taking the flat standard deduction. You take whichever is larger; only the amount above the standard deduction produces extra tax savings.Full definition & example →

J

Joint account: A bank or investment account owned by two or more people, each with full access. Common for household spending between partners; clarity about what flows through it beats assumptions.Full definition & example →Budgeting as a couple →
Joint tenancy with right of survivorship: A way for two or more people to own an asset together in equal shares where, when one owner dies, that owner's share passes automatically to the surviving owner or owners. The transfer happens outside probate and overrides anything a will says. It is the default titling for many married couples' homes and joint accounts, and it differs from tenancy in common, where each owner's share passes through their will.Full definition & example →Protect your progress guide →
Jumbo loan: A mortgage too large to be sold to the government-sponsored agencies, exceeding the conforming loan limits set for each county every year. Because the lender keeps the risk, jumbos demand stronger credit, bigger down payments, meaningful cash reserves, and full documentation.Full definition & example →Mortgage affordability calculator →

L

Lease: A contract granting use of property for a set period at a set payment: an apartment for a year, or a car for two to four years. You are paying for use, not building ownership. Car leases add mileage caps, wear charges, and a residual value you can pay to keep the car at the end.Full definition & example →Lease vs buy car calculator →Rent affordability calculator →
Liability: Anything you owe: mortgage principal, student loans, auto loans, card balances. Assets minus liabilities equals net worth.Full definition & example →Net worth calculator →
Lien: A legal claim against property that secures a debt. Some are voluntary, like a mortgage on a house or a loan on a car; others arrive without consent, like tax liens, judgment liens, and contractor (mechanic's) liens. A lien generally must be paid off before the property can be sold with clear title.Full definition & example →
Lifestyle creep: The tendency for spending to rise automatically with income: each raise upgrades the car, the apartment, and the restaurants until the bigger paycheck saves no more than the old one did.Full definition & example →Savings rate guide →
Limited liability company (LLC): A business structure created under state law that separates the owner's personal assets from the business's debts and lawsuits. For taxes it is a chameleon: a one-owner LLC is taxed like a sole proprietorship by default, a multi-owner LLC like a partnership, and either can elect to be taxed as an S corporation or a C corporation.Full definition & example →Self-employment tax calculator →Irregular income guide →
Liquid net worth: Net worth counting only assets that convert to cash quickly without heavy penalties or forced discounts: cash, savings, and taxable brokerage holdings. Home equity, retirement accounts locked behind early-withdrawal penalties, and vehicles are excluded or steeply discounted.Full definition & example →Net worth calculator →
Liquidity: How quickly an asset converts to spendable cash without losing value. Savings accounts are highly liquid; home equity is not. Emergency money must stay liquid.Full definition & example →
Living trust: A revocable trust you create during your lifetime to hold your assets, with yourself as trustee and a successor trustee named to take over if you become incapacitated or die. Because the trust, not you, technically owns the assets, they pass to your beneficiaries under its terms without going through probate. You can change or cancel it at any time, which is also why it provides no tax savings and no creditor protection.Full definition & example →Protect your progress guide →
Load fund: A mutual fund that charges a sales commission, called a load, paid to the broker or advisor who sells it. A front-end load is taken out of your purchase, a back-end or deferred load is charged when you sell within a set number of years, and level-load share classes charge an ongoing fee instead. No-load funds charge none of these, and every load is on top of the fund's expense ratio.Full definition & example →Investment fee calculator →Start investing guide →
Loan term: How long you have to repay a loan: 60 months on a car loan, 15 or 30 years on a mortgage. For the same amount and rate, a longer term means a smaller monthly payment, slower principal payoff, and more total interest.Full definition & example →Amortization calculator →
Loan-to-value ratio (LTV): The loan balance divided by the property's value, expressed as a percentage. Lenders use LTV to price risk: it decides whether a mortgage needs PMI (above 80%), how large a HELOC can be, and whether a refinance qualifies.Full definition & example →PMI calculator →HELOC calculator →
Long-term capital gains: Profit on an investment held for more than one year before selling, taxed at preferential rates that sit below ordinary income rates, including a 0% rate at lower incomes. Gains on assets held a year or less are short-term and taxed like wages.Full definition & example →Capital gains tax calculator →
Long-term care insurance: Insurance that pays for extended help with daily activities such as bathing, dressing, and eating, whether delivered at home, in assisted living, or in a nursing home. Policies specify a daily or monthly benefit, a benefit period, and an elimination period you must cover yourself before benefits start. Medicare generally does not pay for this kind of custodial care.Full definition & example →Protect your progress guide →Retirement calculator →

M

Margin: Borrowing from your broker against the investments in your account, usually to buy more securities. The portfolio is the collateral: if its value falls too far relative to the loan, the broker issues a margin call demanding more cash, and can sell your holdings without asking in order to cover the loan.Full definition & example →
Marginal tax rate: The tax rate applied to your next dollar of income: the rate of the bracket that dollar lands in, plus any state tax. Under the progressive system it is higher than your effective rate, which averages across all your income.Full definition & example →Paycheck calculator →
Market capitalization: A company's total stock market value: share price multiplied by shares outstanding. It is how companies are sized into large-cap, mid-cap, and small-cap, and it is what most index funds weight holdings by.Full definition & example →
Medicare: The federal health insurance program for people 65 and older and some younger people with disabilities. Part A covers hospital stays and is usually premium-free after a working career. Part B covers doctors and outpatient care for a monthly premium. Part D covers prescription drugs, and Part C (Medicare Advantage) is a private-plan bundle of the pieces. It is the program itself, not the payroll deduction labeled Medicare, which is the tax that funds it.Full definition & example →
Medicare tax: The payroll tax that funds Medicare: 1.45% of wages withheld from the employee and matched by the employer, with no wage cap. High earners pay an extra 0.9% Additional Medicare Tax on wages above a threshold, and the self-employed pay both halves. It funds the insurance program; it is not the program itself.Full definition & example →Paycheck calculator →
Medigap: Private insurance, also called Medicare Supplement, that pays some of the out-of-pocket costs Original Medicare leaves behind: deductibles, coinsurance, and copays. Plans are standardized by letter, so a given plan's benefits are the same from every insurer in most states and only the premium differs. You must be enrolled in both Part A and Part B, and Medigap cannot be combined with a Medicare Advantage plan.Full definition & example →Protect your progress guide →
Mega backdoor Roth: A strategy for getting far more money into Roth accounts than normal limits allow: contribute after-tax (not Roth) dollars to a 401(k) beyond the regular deferral limit, then immediately convert them to the plan's Roth side or roll them into a Roth IRA. It only works if the plan permits both after-tax contributions and in-plan conversions or in-service rollovers.Full definition & example →Retirement accounts guide →
Mileage deduction: The tax deduction self-employed people take for business driving. You can multiply business miles by the standard mileage rate the IRS publishes each year, or deduct the business share of actual car costs such as gas, insurance, repairs, and depreciation. Commuting between home and a regular workplace does not count, and the deduction requires a log of dates, miles, and business purpose.Full definition & example →Self-employment tax calculator →Self-employment tax explained →
Minimum payment: The smallest amount a credit card issuer accepts each month to keep the account current, typically a small percentage of the balance (often 1-3%) or interest plus a sliver of principal. It is designed to keep the account healthy for the lender, not to pay off the debt.Full definition & example →Credit card payoff calculator →
Modified adjusted gross income (MAGI): Adjusted gross income with certain items added back, such as tax-exempt interest or excluded foreign income. Different rules use slightly different MAGI recipes, but it is the eligibility number for Roth IRA contributions, health insurance subsidies, education credits, and income-based Medicare premium surcharges.Full definition & example →Roth IRA calculator →
Money market account: A bank account blending savings-level interest with limited checking features, FDIC-insured at banks. A reasonable home for cash that wants slightly more access than a savings account.Full definition & example →
Money market fund: A mutual fund holding very short-term, high-quality debt (Treasury bills, government paper, top-grade corporate IOUs) that aims to keep its share price fixed at $1.00 while paying yields that track short-term interest rates. It is the default cash parking spot inside brokerage accounts. It is an investment, not a bank deposit: no FDIC insurance, unlike the similarly named money market account.Full definition & example →
Mortgage: A loan secured by real estate, typically 15 or 30 years in the U.S. The property is collateral, so missed payments can end in foreclosure; the interest may be tax-deductible for itemizers.Full definition & example →
Mortgage insurance premium (MIP): The mortgage insurance charged on FHA loans: an upfront premium (a small percentage of the loan, usually rolled into the balance) plus an annual premium paid monthly. Unlike PMI on conventional loans, MIP on a low-down-payment FHA loan generally lasts the life of the loan; the usual exit is refinancing into a conventional loan after building 20% equity.Full definition & example →Refinance calculator →PMI calculator →
Mortgage points: An upfront fee paid at closing to lower a mortgage's interest rate, also called discount points. One point costs 1% of the loan amount and typically trims the rate by around a quarter of a percentage point. The math is a break-even: how many months of payment savings it takes to recover the upfront cost.Full definition & example →Mortgage points calculator →
Municipal bond: A bond issued by a state, city, or local agency to fund public projects. The interest is generally exempt from federal income tax, and often from state tax for in-state residents, which is why munis pay lower stated yields than comparable taxable bonds.Full definition & example →
Mutual fund: A pooled investment priced once daily. Index mutual funds are the classic 401(k) building block; the actively managed variety usually charges more and delivers less.Full definition & example →

N

NCUA insurance: Federal insurance protecting deposits at credit unions, run by the National Credit Union Administration. Coverage is $250,000 per member, per credit union, per ownership category, the direct equivalent of FDIC insurance at banks.Full definition & example →
Net asset value (NAV): The per-share value of a fund: total assets minus liabilities, divided by shares outstanding. Mutual funds price and trade at NAV once a day after markets close; ETFs trade all day at market prices that hover near NAV.Full definition & example →
Net income (take-home pay): What actually lands in your account after taxes, insurance premiums, and payroll deductions. Budgets and savings rates should be calculated on net income.Full definition & example →
Net worth: Everything you own minus everything you owe: the single best summary of financial position. Direction matters more than level; track it monthly or quarterly.Full definition & example →Net worth calculator →U.S. medians by age →
Nonsufficient funds (NSF) fee: A fee charged when a check or electronic payment bounces because the account lacks the money and the bank returns it unpaid. It differs from an overdraft fee, where the bank covers the shortfall; with NSF, the payment fails and the payee may add its own returned-payment fee.Full definition & example →

O

Open enrollment: The annual window, typically in the fall, when you can choose or change employer health insurance and other workplace benefits for the coming year. Outside the window, changes generally require a qualifying life event such as marriage, a birth, or a job change.Full definition & example →HSA calculator →
Opportunity cost: What the money could have earned elsewhere. A $200 monthly subscription bundle is also the ~$35,000 it could have compounded into over a decade; opportunity cost is that second price tag.Full definition & example →Subscription cost calculator →
Options contract: A contract giving the right, not the obligation, to buy (a call) or sell (a put) 100 shares of a stock at a set strike price before an expiration date. Buyers pay a premium for that right; many options expire worthless, and the premium is the buyer's maximum loss.Full definition & example →Start investing guide →
Ordinary income: Income taxed at the regular federal bracket rates: wages, self-employment earnings, interest, short-term capital gains, and most traditional retirement account withdrawals. It contrasts with long-term capital gains and qualified dividends, which get lower preferential rates.Full definition & example →Capital gains tax calculator →Paycheck calculator →
Origination fee: An upfront fee a lender charges for processing and funding a loan, usually a percentage of the amount borrowed. On mortgages it appears in closing costs; on personal loans it is often deducted from the money you receive.Full definition & example →Personal loan calculator →Closing cost calculator →
Out-of-pocket maximum: The most you pay for covered, in-network care in a plan year, counting deductibles, copays, and coinsurance but not premiums. Once you hit it, the plan pays 100% of covered costs for the rest of the year.Full definition & example →Emergency fund calculator →
Overdraft: Spending more than a checking account holds. Banks may cover it for a fee per transaction; declining overdraft coverage on debit purchases is usually the cheaper choice.Full definition & example →

P

Pass-through income: Business profit that is not taxed at the business level but passes through to the owners' personal tax returns, where it is taxed at their individual rates. Sole proprietorships, partnerships, most LLCs, and S corporations all work this way, in contrast to a C corporation, which pays its own corporate tax before distributing dividends that are taxed again.Full definition & example →Self-employment tax calculator →Quarterly tax calculator →
Pay stub: The statement that accompanies each paycheck, showing gross pay, every tax withheld, benefit and retirement deductions, and net pay, plus year-to-date totals. It is the primary record of where your earnings actually go.Full definition & example →Paycheck calculator →
Pay yourself first: A budgeting rule that routes savings and investments out of your paycheck automatically before any spending happens, treating wealth-building as the first bill of the month rather than whatever is left over.Full definition & example →Savings rate calculator →
Payday loan: A small, short-term loan due on your next payday, typically $100-1,000, with fees that work out to triple-digit annual rates, often 300-400% APR or more. It is among the most expensive legal ways to borrow, and many borrowers roll one loan into the next.Full definition & example →Emergency fund calculator →Personal loan calculator →
Payroll tax: Taxes on wages that fund Social Security and Medicare, collected through FICA: employees and employers each pay half, and self-employed people pay both halves as self-employment tax. They apply from the first dollar of wages, separately from federal income tax.Full definition & example →Paycheck calculator →Self-employment tax calculator →
Pension: A retirement plan where the employer promises a defined monthly benefit for life, usually based on salary and years of service, and bears the investment risk. Now rare in the private sector, pensions remain common in government, education, and union jobs.Full definition & example →Annuity calculator →Retirement calculator →
Per stirpes: A beneficiary instruction, Latin for by branch, meaning that if a named beneficiary dies before you, that person's share passes down to their descendants rather than being split among your surviving beneficiaries. The alternative, per capita, divides everything among the beneficiaries who are still living. The words appear on wills, trusts, and retirement account beneficiary forms.Full definition & example →Protect your progress guide →
PITI (principal, interest, taxes, insurance): The four parts of a full monthly mortgage payment: loan principal, interest, property taxes, and homeowners insurance, with the last two usually collected through escrow. Lenders qualify buyers on the whole PITI number, not just principal and interest.Full definition & example →Mortgage calculator →Mortgage affordability calculator →
Portfolio: All your investments viewed as one whole. Allocation and fees at the portfolio level matter far more than any single holding.Full definition & example →
Power of attorney (POA): A legal document naming someone to act on your behalf, financially or medically, if you cannot. A durable financial POA stays valid through incapacity, which is exactly when it is needed.Full definition & example →
Premium: The recurring price of an insurance policy. Compare policies on the worst case (premium plus out-of-pocket maximum), not the monthly price alone.Full definition & example →
Prenuptial agreement: A contract two people sign before marrying that sets out how assets, debts, and income will be treated during the marriage and divided if it ends in divorce or death, replacing the default rules of their state. To hold up it must be in writing, signed voluntarily well before the wedding, and based on full financial disclosure, usually with each side advised by their own lawyer. It cannot decide child custody or child support.Full definition & example →Money as a couple guide →How to talk money with your partner →
Present value: What a future sum of money is worth today, after discounting for the return you could earn in the meantime. It is compound interest run backward: $1,100 a year from now is worth $1,000 today at a 10% discount rate.Full definition & example →Compound interest calculator →
Price-to-earnings ratio (P/E): A stock's price divided by its earnings per share: how many dollars investors pay for each dollar of annual profit. A high P/E signals high growth expectations; a low one signals cheapness, doubt, or a slow-growing business.Full definition & example →Start investing guide →
Prime rate: The benchmark rate banks charge their most creditworthy business customers, which moves in lockstep with the Federal Reserve's policy rate. Many consumer rates, especially credit cards and HELOCs, are set as prime plus a margin.Full definition & example →HELOC calculator →
Principal: The core amount borrowed or invested, as opposed to the interest it generates. Extra debt payments should be applied to principal, which shrinks all future interest.Full definition & example →
Private mortgage insurance (PMI): Insurance protecting the lender, charged when a down payment is under 20%. You can request removal at 20% equity, and it must end automatically at 22%; until then it is pure cost to you.Full definition & example →
Pro-rata rule (backdoor Roth): The IRS rule that treats all of your traditional, SEP, and SIMPLE IRAs as a single pot when you convert any of it to a Roth. The taxable share of a conversion equals the pre-tax share of that combined balance, so you cannot choose to convert only the after-tax dollars. Roth IRAs and workplace plans such as a 401(k) are not counted.Full definition & example →Backdoor Roth IRA guide →Roth IRA calculator →
Probate: The court process that validates a will (or applies state law without one), pays the estate's debts, and distributes what remains. It is public, can take months to over a year, and costs fees; assets with beneficiary designations or held in trusts and joint accounts skip it entirely.Full definition & example →Protect your progress guide →
Property tax: An annual local tax on real estate, calculated as the area's rate applied to the property's assessed value. It funds schools and local services, and for most homeowners it rides along with the mortgage payment through escrow.Full definition & example →Property tax calculator →
Public Service Loan Forgiveness (PSLF): A federal program that forgives the remaining balance on eligible federal student loans after a borrower makes a required number of qualifying monthly payments, measured in years of full-time work for a qualifying employer, typically a government agency or a nonprofit. Payments count only when made under a qualifying repayment plan, usually an income-driven one, while working for a qualifying employer.Full definition & example →Student loan calculator →Debt payoff guide →

Q

Qualified business income (QBI) deduction: A personal tax deduction for owners of pass-through businesses, meaning sole proprietors, partners, S corporation shareholders, and some landlords, equal to up to 20% of the business's qualified income. It is taken on the owner's return whether or not they itemize, and it does not reduce self-employment tax. Above income thresholds the IRS adjusts each year the deduction phases down, and owners of certain professional service businesses can lose it entirely.Full definition & example →Self-employment tax calculator →Self-employment tax explained →
Qualified charitable distribution (QCD): A donation sent directly from a traditional IRA to a charity, available once the owner reaches the qualifying age (70½ under current law). The amount counts toward any required minimum distribution for the year but is excluded from taxable income entirely.Full definition & example →RMD calculator →
Qualified dividend: A dividend that meets IRS rules, mostly about how long you held the shares, and is therefore taxed at the lower long-term capital gains rates instead of ordinary income rates. Most dividends from U.S. companies held for more than about 60 days qualify; REIT dividends and bond interest generally do not.Full definition & example →Dividend calculator →Capital gains tax calculator →
Qualified domestic relations order (QDRO): A court order, issued as part of a divorce or separation, that directs a workplace retirement plan such as a 401(k) or pension to pay part of a participant's benefit to a former spouse or dependent. Plans cannot split an account without one, no matter what the divorce decree says. IRAs are divided by a simpler transfer written into the decree and do not need a QDRO.Full definition & example →Retirement accounts guide →Money as a couple guide →

R

Rate buydown (temporary and permanent): Paying money up front, usually at closing, to lower a mortgage's interest rate. A permanent buydown uses discount points to reduce the rate for the life of the loan. A temporary buydown, such as a 2-1 buydown, lowers the rate for the first year or two and then steps up to the full note rate, and is often funded by the seller or builder as an incentive.Full definition & example →Mortgage points calculator →Mortgage points explained →
Real estate investment trust (REIT): A company that owns income-producing real estate and pays out most of its profits as dividends. REIT index funds add real estate exposure without buying property.Full definition & example →
Rebalancing: Restoring your portfolio to its target allocation, usually once a year, by trimming what grew and adding to what lagged. It quietly enforces buying low and selling high.Full definition & example →
Recession: A broad, sustained decline in economic activity: output shrinks, unemployment rises, and spending falls, typically for months or longer. Recessions are officially dated only in hindsight, often after the recovery has already begun.Full definition & example →Emergency fund calculator →
Refinancing: Replacing a loan with a new one at better terms. Powerful for private loans and mortgages when rates drop; refinancing federal student loans into private ones permanently gives up federal protections.Full definition & example →
Rent-to-income ratio: Monthly rent divided by gross monthly income. The classic guideline caps it at 30%, and most landlords screen applicants for income of at least 3x the rent, which is the same line from the other side.Full definition & example →Rent affordability calculator →
Renters insurance: Insurance covering a tenant's belongings, personal liability, and extra living costs if the rental becomes unlivable. The landlord's policy covers the building only, not anything you own inside it.Full definition & example →Protect your progress guide →
Repossession: A lender taking back collateral, most commonly a car, after missed payments on a secured loan. In many states it can happen without a court order once the loan is in default, and the borrower can still owe money afterward.Full definition & example →Auto loan calculator →
Required minimum distribution (RMD): Mandatory annual withdrawals from traditional retirement accounts starting in your mid-70s (age 73 today, 75 for younger cohorts). Roth IRAs have no RMDs during the owner's lifetime.Full definition & example →
Restricted stock units (RSUs): Company stock promised to an employee that turns into actual shares on a vesting schedule. At each vest, the shares' market value is taxed as ordinary income like a cash bonus; any later gain or loss from that point is a capital gain or loss.Full definition & example →Bonus tax calculator →Capital gains tax calculator →
Revolving credit: Credit you can borrow, repay, and borrow again up to a limit, with no fixed end date: credit cards and HELOCs are the main examples. It contrasts with installment loans, which are borrowed once and repaid on a schedule.Full definition & example →Credit utilization calculator →Credit card payoff calculator →
Robo-advisor: An automated service that invests your money in index-fund portfolios and rebalances for a small fee on top of fund costs. A reasonable hands-off option; a DIY three-fund portfolio does the same for less.Full definition & example →
Rollover: Moving retirement money between accounts, typically an old 401(k) into an IRA or a new employer's plan. Always request a direct rollover; taking the money as a check risks taxes and penalties.Full definition & example →
Roth 401(k): A 401(k) option funded with after-tax payroll dollars: no tax deduction today, but qualified withdrawals in retirement, including all the growth, are tax-free. Unlike a Roth IRA it has no income limit, and employer matching dollars are typically contributed pre-tax unless the plan offers Roth matching.Full definition & example →Roth vs. traditional calculator →Retirement accounts guide →
Roth conversion: Moving money from a pre-tax retirement account, such as a traditional IRA or 401(k), into a Roth account. The converted amount is taxed as ordinary income in the year of the conversion, and in exchange all future growth and qualified withdrawals are tax-free. There is no income limit and no cap on how much you can convert, and a conversion cannot be undone.Full definition & example →Roth vs. traditional calculator →Roth vs. traditional IRA →
Roth conversion ladder: An early-retirement strategy of converting a slice of pre-tax retirement money to a Roth IRA every year, then withdrawing each converted amount five years later. Converted principal can be taken out penalty-free once its own five-year clock has run, even before 59½, so a series of annual conversions produces a series of penalty-free withdrawals that starts five years after the first rung.Full definition & example →FIRE calculator →Roth vs. traditional calculator →
Roth five-year rule: The rule that earnings in a Roth IRA can only be withdrawn tax-free once five tax years have passed since your first Roth IRA contribution, in addition to being at least 59½ or meeting another qualifying reason. A separate five-year clock applies to each Roth conversion for penalty purposes for people under 59½. Contributions themselves can come out at any time without tax or penalty.Full definition & example →Roth IRA calculator →Retirement accounts guide →
Roth IRA: An IRA funded with after-tax dollars: no deduction now, but growth and qualified withdrawals are completely tax-free. Contributions (not earnings) can be withdrawn anytime, and eligibility phases out at higher incomes.Full definition & example →Traditional vs. Roth →
Routing number: The nine-digit code identifying a U.S. bank or credit union in the payment system, used with your account number for direct deposit, ACH transfers, and checks. The routing number identifies the institution; the account number is the private half of the pair.Full definition & example →
Rule of 55: An IRS exception that lets you withdraw from your current employer's 401(k) or 403(b) without the 10% early-withdrawal penalty if you leave that job in or after the calendar year you turn 55 (age 50 for certain public safety employees). Income tax still applies. The exception covers only that employer's plan: it does not extend to IRAs, to plans from earlier jobs, or to money rolled out of the plan into an IRA.Full definition & example →401(k) calculator →Retirement withdrawal calculator →
Rule of 72: A mental shortcut for compounding: divide 72 by an annual growth rate to estimate the years needed for money to double. It works in reverse too (72 divided by years gives the required rate) and applies to costs like inflation and fees as well as returns.Full definition & example →Rule of 72 calculator →Compound interest calculator →

S

S corporation: A tax election, not a separate kind of business, that an LLC or corporation can make with the IRS. The business remains a pass-through, but an owner who works in it must be paid a reasonable salary through payroll, subject to Social Security and Medicare taxes, and only the profit left after that salary is distributed to the owner free of self-employment tax.Full definition & example →Self-employment tax calculator →Self-employment tax explained →
Savings rate: The percentage of take-home pay that builds net worth: savings, investments, and extra debt principal. It predicts your timeline to financial independence better than income does.Full definition & example →Savings rate calculator →What counts as good →
Schedule C: The IRS form where sole proprietors and single-member LLC owners report business income and expenses alongside their personal return. Revenue minus deductible expenses produces net profit, which flows into total income and is the base for self-employment tax.Full definition & example →Self-employment tax calculator →Quarterly tax calculator →
Section 179 deduction: A tax provision that lets a business deduct the full cost of qualifying equipment, machinery, vehicles, software, and certain building improvements in the year they are put into use, instead of depreciating the cost over several years. The deduction is limited to the business's taxable income for the year, so it cannot create a loss, and it is subject to an annual dollar cap the IRS adjusts, with tighter limits for passenger vehicles.Full definition & example →Self-employment tax calculator →Quarterly tax calculator →
Secured credit card: A credit card backed by a refundable cash deposit, which usually sets the credit limit. It works like any card and reports to the credit bureaus, making it the standard tool for building credit from nothing or rebuilding after damage.Full definition & example →Credit utilization calculator →
Secured debt: Debt backed by collateral the lender can take, like a mortgage (house) or auto loan (car). Rates are lower than unsecured debt because the lender's risk is lower; yours is higher.Full definition & example →
Security deposit: Money a landlord holds during a lease as protection against damage or unpaid rent, commonly around one month's rent. Many states cap the amount and set deadlines for returning it, minus documented deductions, after move-out.Full definition & example →Rent affordability calculator →
Self-employment tax: The 15.3% tax self-employed workers pay to cover both halves of Social Security and Medicare (employees split it with their employer). It applies to net self-employment earnings on top of regular income tax.Full definition & example →
SEP IRA: A retirement account for the self-employed and small business owners allowing contributions of up to 25% of net self-employment earnings, with a far higher dollar ceiling than a regular IRA.Full definition & example →Retirement accounts guide →
Sequence-of-returns risk: The risk that bad market years arrive early in retirement, while you are withdrawing, and permanently shrink the portfolio. Two retirees can earn the same average return over 30 years and end up in wildly different places depending on the order of the good and bad years.Full definition & example →Retirement withdrawal calculator →
Series I savings bond (I bond): A U.S. savings bond whose interest rate combines a fixed rate for the life of the bond with an inflation adjustment that resets every six months. Bought directly from the Treasury with an annual purchase cap per person, it cannot be redeemed in the first 12 months, and cashing out before five years forfeits the last three months of interest. Interest is exempt from state tax and federally tax-deferred until redemption.Full definition & example →Inflation calculator →
Severance pay: Money an employer pays a worker whose job is being eliminated, most often calculated as a number of weeks of pay per year of service. No federal law requires it; it is usually offered in exchange for signing a release of legal claims, sometimes alongside continued health coverage or job-placement help. It is taxed as wages, typically as a lump sum with supplemental-wage withholding.Full definition & example →Why your bonus looks so heavily taxed →Emergency fund calculator →
Short sale (real estate): Selling a home for less than the mortgage balance, with the lender's approval, because the owner is underwater and cannot keep paying. The lender agrees to accept the sale proceeds and either forgives or negotiates the shortfall. (Shorting a stock is an unrelated concept: a bet that a share price will fall.)Full definition & example →
Simple interest: Interest calculated only on the original principal, never on accumulated interest. A loan or investment at simple interest grows in a straight line, unlike compound interest, which grows on itself.Full definition & example →Simple interest calculator →
SIMPLE IRA: A retirement plan for small employers that lets employees defer salary into their own account with minimal paperwork. Employers must contribute, typically by matching employee contributions up to a small percentage of pay (commonly 3%) or making a flat contribution for everyone.Full definition & example →Retirement accounts guide →
Sinking fund: Monthly savings toward a predictable irregular expense: insurance premiums, holidays, car repairs. Sinking funds are how budgets absorb annual bills without drama.Full definition & example →Sinking funds guide →
Social Security: The federal retirement benefit funded by payroll taxes. You can claim as early as 62 at a reduced amount; full retirement age is 67 for most current workers, and delaying to 70 increases the benefit roughly 8% per year.Full definition & example →
Soft inquiry: A credit check that does not affect your score: checking your own credit, pre-qualified offers, background checks, and account reviews by existing lenders. Only hard inquiries, triggered by actual credit applications, can cost points.Full definition & example →
Sole proprietorship: The default business structure for one person earning money on their own: no entity is formed, and legally the owner and the business are the same. Profit is reported on Schedule C of the owner's personal return and is subject to both income tax and self-employment tax. The owner is personally responsible for every debt and lawsuit of the business.Full definition & example →Self-employment tax calculator →Freelance rate calculator →
Solo 401(k): A 401(k) for a business owner with no employees (a spouse is allowed). You contribute as both employee and employer, so the total limit is the highest available to most self-employed savers, and a Roth option exists.Full definition & example →Retirement accounts guide →
Spousal IRA: An IRA funded for a spouse who has little or no earned income, based on the working spouse's income. The couple must file a joint return; the account belongs entirely to the non-working spouse and can be traditional or Roth.Full definition & example →Retirement accounts guide →
Stablecoin: A cryptocurrency designed to hold a fixed value, usually pegged to one U.S. dollar, by holding reserves or using other stabilization mechanisms. It trades on crypto rails but aims for none of crypto's price swings.Full definition & example →
Standard deduction: The flat amount every filer can subtract from income before tax, no receipts required. Most Americans take it rather than itemizing; the IRS adjusts it annually.Full definition & example →
Statement balance: What you owed on a credit card when the billing cycle closed. Paying the full statement balance by the due date keeps the grace period alive, so purchases never accrue interest; the current balance also includes newer purchases that are not due yet.Full definition & example →Credit card payoff calculator →
Step-up in basis: The rule that resets the cost basis of an inherited asset to its fair market value on the date the owner died. The capital gain that built up during the owner's lifetime is never taxed; the heir owes tax only on growth after the death. It applies to inherited assets, not to gifts made during life, which carry the giver's original basis, and not to retirement accounts, whose withdrawals are taxed as ordinary income regardless.Full definition & example →Capital gains tax calculator →Capital gains tax explained →
Stock: A share of ownership in a company. Individual stocks can go to zero; the diversified alternative is owning thousands at once through an index fund.Full definition & example →
Stock option: The right, but not the obligation, to buy shares at a set strike price. Employee options vest over time and pay off only if the stock rises above the strike; the tax treatment differs by option type and by when you exercise and sell.Full definition & example →
Stock split: A company dividing each existing share into several, cutting the price per share proportionally. Your total value does not change; you simply hold more shares at a lower price, and your cost basis per share divides by the same ratio.Full definition & example →
Subsidized loan: A federal student loan, awarded to undergraduates based on financial need, on which the government pays the interest while the student is enrolled at least half-time, during the grace period after leaving school, and during approved deferments. The balance at the start of repayment is exactly what was borrowed. Unsubsidized loans, by contrast, accrue interest from the day the money is disbursed.Full definition & example →Student loan calculator →Debt payoff guide →
Substantially equal periodic payments (72(t) / SEPP): An IRS exception that lets you take penalty-free withdrawals from an IRA or a former employer's 401(k) before 59½ by committing to a fixed series of annual payments calculated from your account balance and life expectancy using one of three IRS-approved methods. Income tax still applies. The schedule must continue for five years or until you reach 59½, whichever is longer.Full definition & example →Retirement withdrawal calculator →FIRE calculator →
Supplemental wages: Pay outside the regular paycheck: bonuses, commissions, severance, overtime, and similar. Employers commonly withhold federal tax on these at a flat percentage set by the IRS rather than your W-4 rate, which is why a bonus check looks unexpectedly small.Full definition & example →Bonus tax calculator →

T

Target-date fund: A single fund that holds a full diversified portfolio and automatically shifts toward bonds as its labeled year approaches. The one-decision investing option, common as a 401(k) default.Full definition & example →
Tax bracket: The rate applied to your last dollar of income under the progressive U.S. system. Moving into a higher bracket only taxes the income inside that bracket, never your whole paycheck.Full definition & example →
Tax credit: A dollar-for-dollar reduction of your tax bill, applied after the tax is calculated. Refundable credits can push the bill below zero and come back as a refund; nonrefundable credits can only shrink the bill to zero.Full definition & example →
Tax deduction: An amount subtracted from your income before tax is calculated, either through the standard deduction or by itemizing. Its cash value equals the deduction times your marginal rate, so the same deduction saves more for higher earners.Full definition & example →
Tax drag: The reduction in a taxable investment account's growth caused by the taxes paid each year on dividends, interest, and capital gains distributions, and on gains realized by trading. It is usually expressed as a yearly percentage subtracted from the return, the same way an expense ratio is, and it does not apply inside tax-advantaged accounts.Full definition & example →Investment fee calculator →Tax-loss harvesting guide →
Tax-advantaged account: Any account with special tax treatment: 401(k)s, IRAs, HSAs, and 529s. Using them in the right order is worth six figures over a career versus investing the same money in a taxable account.Full definition & example →The funding order →
Tax-loss harvesting: Selling an investment at a loss to offset taxable gains (plus up to $3,000 of ordinary income per year), then reinvesting in something similar but not substantially identical. The wash-sale rule voids the loss if you rebuy the same security within 30 days.Full definition & example →
Taxable income: The income your tax brackets actually apply to: gross income minus adjustments (giving AGI), minus the standard deduction or itemized deductions. It is almost always meaningfully lower than your salary.Full definition & example →Paycheck calculator →
Term life insurance: A pure death benefit covering a fixed period, priced cheaply while young and healthy. The standard sizing is roughly 10-12 times income if anyone depends on your paycheck; without dependents you likely need none.Full definition & example →
Thrift Savings Plan (TSP): The retirement plan for federal employees and uniformed service members, working like a 401(k): payroll contributions, traditional or Roth treatment, and a small menu of extremely low-cost index funds. Most participants also receive automatic and matching agency contributions.Full definition & example →401(k) calculator →
Title insurance: A one-time policy bought at closing that protects against defects in a home's ownership history: forged deeds, unknown heirs, unpaid liens from prior owners. Lenders require a policy protecting the loan; an owner's policy protecting your equity is optional but standard.Full definition & example →Closing cost calculator →
Traditional IRA: An IRA funded with money that may be tax-deductible now, growing tax-deferred until withdrawal, when it is taxed as ordinary income. Deductibility can phase out if a workplace plan covers you, and required minimum distributions eventually apply.Full definition & example →Roth vs. traditional calculator →Retirement accounts guide →
Transfer on death (TOD) designation: A designation on a brokerage or bank account naming who receives it directly at your death, bypassing probate entirely. Like beneficiary designations on retirement accounts, a TOD overrides whatever your will says about that account.Full definition & example →
Treasury Inflation-Protected Securities (TIPS): U.S. Treasury bonds whose principal adjusts with the Consumer Price Index, so both the principal and the interest paid on it rise with inflation. At maturity you receive the greater of the adjusted or original principal, backed by the federal government.Full definition & example →Inflation calculator →
Treasury securities: Debt issued by the U.S. government: T-bills (under a year), notes, and bonds. Backed by the federal government, exempt from state income tax, and the benchmark for safe yield.Full definition & example →
Trust: A legal arrangement where a trustee holds and manages assets for named beneficiaries under written rules. A revocable living trust, the most common kind, lets you control everything while alive and passes assets at death without probate.Full definition & example →

U

Umbrella insurance: Extra liability coverage (commonly 1-2 million dollars) that sits on top of auto and home policies. Inexpensive protection once your net worth is large enough to be worth suing.Full definition & example →
Underwriting: The lender's or insurer's process of verifying risk before final approval: for a mortgage, that means documenting income, assets, debts, and credit, and appraising the property. Pre-approval is an estimate; underwriting is the exam.Full definition & example →Debt-to-income calculator →
Unemployment insurance: A state-run program, funded by taxes on employers, that pays weekly benefits to workers who lose a job through no fault of their own and are able to work and actively looking. Benefits replace a fraction of prior wages up to a weekly cap set by each state, for a limited number of weeks. Quitting voluntarily or being fired for misconduct usually disqualifies a claim, and benefits are taxable income.Full definition & example →Emergency fund calculator →Emergency fund guide →
Unsecured debt: Debt with no collateral behind it, like credit cards and most personal loans. Lenders price the extra risk as higher APRs, which is why unsecured balances are usually the first to pay off.Full definition & example →
Unsubsidized loan: A federal student loan available to undergraduate and graduate students regardless of financial need, on which interest accrues from the day the money is disbursed, including while the student is in school and during the grace period. Any interest unpaid when repayment begins is capitalized, meaning it is added to the principal and starts earning interest itself.Full definition & example →Student loan calculator →Debt payoff guide →

V

VA loan: A mortgage guaranteed by the Department of Veterans Affairs for eligible veterans, service members, and some surviving spouses. It allows no down payment and charges no monthly mortgage insurance; most borrowers pay a one-time funding fee instead, which can roll into the loan.Full definition & example →Mortgage calculator →
VantageScore: A credit scoring model created jointly by the three national credit bureaus, scored on the same 300-850 range as FICO but with different math. Free credit apps and card dashboards often show a VantageScore, while most lenders still pull a FICO score for decisions.Full definition & example →
Variable expenses: Costs that change month to month, like groceries, gas, dining out, and utilities, in contrast to fixed expenses such as rent and insurance. They are where budgets actually flex, for better and worse.Full definition & example →50/30/20 calculator →
Vesting: The schedule on which employer-contributed money (401(k) match, equity grants) becomes truly yours. Your own contributions are always 100% vested; leaving before a vesting date can forfeit employer money.Full definition & example →
Volatility: How much an investment's price swings. Stocks are volatile in any given year and remarkably consistent over decades; volatility is the price of admission for long-term returns, not a malfunction.Full definition & example →

W

W-2: The annual form employers send reporting your wages and the taxes withheld. It is the backbone of most Americans' tax returns.Full definition & example →
W-4: The form you give an employer to set paycheck tax withholding. A huge refund means your W-4 over-withholds: you lent the government money at 0% all year.Full definition & example →
W-9: The IRS form a freelancer, contractor, landlord, or investor hands to whoever will pay them, not to the IRS. It supplies your legal name, address, and taxpayer identification number (a Social Security number or an employer identification number) and certifies that you are not subject to backup withholding, so the payer can report what it paid you on a 1099 at year end.Full definition & example →W-2 vs 1099 →Quarterly tax calculator →
Wash-sale rule: An IRS rule that disallows a capital loss if you buy the same or a substantially identical security within 30 days before or after the sale. The disallowed loss is added to the cost basis of the replacement shares, and the rule reaches across your accounts, including IRAs.Full definition & example →Capital gains tax calculator →
Whole life insurance: Permanent life insurance that lasts your whole life and builds cash value, at premiums many times higher than term coverage for the same death benefit. The cash value grows slowly and surrendering in the early years often returns less than the premiums paid.Full definition & example →Life insurance calculator →
Will: The legal document directing where your assets go and who cares for minor children. Beneficiary designations on accounts override it, so the two need to agree.Full definition & example →Protection guide →
Wire transfer: A bank-to-bank transfer that moves money the same day, usually within hours, for a fee, commonly around $25-35 to send domestically. Wires are effectively final once sent, which is why they are standard for home closings and other large, time-sensitive payments.Full definition & example →
Withholding: Taxes taken out of each paycheck and sent to the IRS on your behalf, controlled by your W-4. The goal is to land close to your actual tax bill: neither a scary balance due nor a giant refund.Full definition & example →

Y

Yield: The income an investment produces per year as a percentage of its price: interest from savings and bonds, dividends from stocks. Chasing unusually high yield always means accepting unusual risk, seen or unseen.Full definition & example →
Yield curve: A line plotting the yields of U.S. Treasury securities against their maturities, from a few weeks out to 30 years. Normally it slopes upward, since lenders demand more to lock money up longer; it is flat when short and long yields are similar and inverted when short-term yields exceed long-term ones. Inversions have historically preceded recessions, though the timing varies.Full definition & example →CD calculator →Start investing guide →

Z

Zero-based budgeting: A method where every dollar of income is assigned a job (spending, saving, or debt) until income minus assignments equals zero. Maximum clarity, maximum maintenance.Full definition & example →Zero-based budgeting explained →
