Three bites out of one withdrawal
Cashing out a 401(k) before 59½ triggers three separate charges, and they stack. First, the IRS adds a 10% additional tax on the amount, simply for taking it early. Second, the withdrawal is ordinary income, so it lands on top of everything else you earned this year and is taxed at your marginal federal rate, sometimes pushing the last dollars into a higher bracket. Third, most states tax it as income too. The calculator stacks the withdrawal on the taxable income you enter, works out the federal and state tax on just that slice, adds the penalty when it applies, and shows what is left.
A $20,000 withdrawal at 35, line by line
A single filer in Colorado with $60,000 of taxable income takes $20,000 out of an old 401(k) at 35. The penalty is $2,000. Federal income tax on the slice comes to $4,400, and state tax adds $880. Total cost: $7,280, so $12,720 actually arrives, about 64% of the balance. Left alone at 7% for 20 years, that same $20,000 would have grown to roughly $77,394, which is the number the withdrawal really costs.
Withholding is not the tax
When a plan pays you directly, it is generally required to withhold 20% for federal tax, so the check is smaller than the amount you requested. That withholding is a deposit, not the bill. The real tax is settled on your return: if your bracket plus the penalty add up to more than what was withheld, you owe the difference in April; if less, some of it comes back. The calculator shows the real bill, which is why it can differ from what lands in your bank account.
Exceptions, and what they do not waive
The penalty has exceptions written as plain circumstances rather than loopholes: leaving your employer in or after the year you turn 55, a permanent disability, unreimbursed medical bills above a threshold, a court-ordered split of the account in a divorce, a series of substantially equal payments over your life expectancy, and a handful of others. Flip the exception switch to see the effect, and notice what it does: an exception removes the 10% penalty only. The federal and state income tax stay exactly where they were.
When this number is worth running
Run it before any withdrawal you are not forced into. If the money is for an emergency, compare the bite with a 401(k) loan, which many plans allow and which you repay to yourself with interest instead of losing to tax, or with a hardship withdrawal, which still owes tax and usually the penalty but avoids liquidating the whole account. A job change is the other common moment: rolling the balance to an IRA or the new plan keeps every dollar invested, and the 401(k) calculator shows what those dollars keep doing there. If there is no cushion yet, the emergency fund calculator sizes the one that makes this page unnecessary.
Frequently asked questions
How much tax do I pay on an early 401(k) withdrawal?
Three charges stack: a 10% additional federal tax for taking the money before 59½, ordinary federal income tax at your marginal bracket because the withdrawal counts as income for the year, and state income tax in most states. On a mid-sized withdrawal the combined bite often lands somewhere between a quarter and a half of the amount, depending on your bracket and your state.
What counts as an early 401(k) withdrawal?
Any distribution you take before age 59½ that is not rolled over to another retirement account and does not fit one of the IRS exceptions. A loan from your plan is not a distribution as long as you repay it on schedule; a loan that goes into default is treated as a withdrawal and taxed like one.
Why is my check smaller than the amount I requested?
Plans generally withhold 20% for federal income tax when they pay you directly, and some states require withholding too. That is a prepayment, not the final bill. Your actual tax and any penalty are figured on your return, so you may owe more in April or get part of the withholding back, depending on your bracket.
Can I avoid the early withdrawal penalty?
Sometimes. Exceptions include leaving your employer in or after the year you turn 55, permanent disability, large unreimbursed medical expenses, a court-ordered split of the account in a divorce, and taking substantially equal periodic payments over your life expectancy. An exception waives only the 10% penalty; the income tax still applies. A 401(k) loan, where your plan offers one, avoids both.
How accurate is this calculator?
It stacks the withdrawal on top of the taxable income you enter and applies the federal brackets and statewide rates for 2026, so the tax shown is the marginal cost of the withdrawal itself rather than an average rate.
