0–9
- 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 →
- 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 →
- 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 →
- 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 →
- 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
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
B
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 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 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 →
- 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 →
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 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 →
- 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 →
- 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 →
E
- 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 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 →
- 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 →
- 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
- 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 →
- 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 →
G
- 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 →
- 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-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 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 →
I
- 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 →
- 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 →
- 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 →
- 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 →
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 →
L
- Liability
- Anything you owe: mortgage principal, student loans, auto loans, card balances. Assets minus liabilities equals net worth.Full definition & example →Net worth calculator →
- 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 →
- 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 →
M
- 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 →
- 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 →
- 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
- 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 →
O
- 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 →
- 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
- 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 →
- 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 →
- 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 →
R
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 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 →
S
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
- 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 →
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-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 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-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 →
- 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 →
- 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 →
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 →
- 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 →
V
- 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 →
- 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 →
- 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 →
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 →
