How to use the 401(k) Early Withdrawal Calculator
Enter the amount you plan to withdraw and your age on the withdrawal date.
Pick a penalty exception if one applies, such as the Rule of 55.
Choose how to estimate federal tax: from 2026 brackets using your filing status and other income, or with your own rate.
Add your state income tax rate, expected return and retirement age.
Read the cash you keep, the breakdown of penalty and taxes, and the growth you would give up.
How the early withdrawal cost is calculated
A traditional 401(k) withdrawal before age 59½ is hit three ways:
10% additional tax (the penalty) = withdrawal × 10%, unless an exception applies.
Federal income tax = tax on (other income + withdrawal − standard deduction) − tax on (other income − standard deduction). Using the difference captures any jump into a higher bracket.
State income tax = withdrawal × your state rate (many states also tax retirement withdrawals as ordinary income).
Net received = withdrawal − penalty − federal tax − state tax. The opportunity cost compares that cash with what the full amount could grow to: FV = withdrawal × (1 + r)years.
Example: a single filer, age 40, with $60,000 of other income withdraws $25,000. The penalty is $2,500, the extra federal tax is about $4,850 ($780 at 12% plus $4,070 at 22%), and a 5% state tax adds $1,250, leaving about $16,400, only 66% of the withdrawal.

Common exceptions to the 10% penalty (401(k) plans)

Borrow instead: a 401(k) loan avoids tax and penalty if you repay it. Compare with the 401(k) loan calculator.
Roll over an old 401(k) into an IRA or a new employer plan when you change jobs, rather than taking cash.
Withdraw only what you need: a smaller amount can keep you in a lower bracket.
Spread it across tax years (for example December and January) to split the income.
Frequently asked questions
How much is the penalty for an early 401(k) withdrawal?
The IRS adds a 10% additional tax on the taxable amount withdrawn from a 401(k) before age 59½, unless an exception applies. It comes on top of regular income tax, so the total cost often reaches 30% to 40% of the withdrawal.
How is a 401(k) withdrawal taxed?
Pre-tax (traditional) 401(k) money is taxed as ordinary income in the year you take it out. The calculator adds the withdrawal to your other income and measures how much extra federal tax that creates with the 2026 brackets, then adds your state rate and any penalty.
What is the Rule of 55?
If you leave your job (quit, laid off or retired) in or after the calendar year you turn 55, withdrawals from that employer's 401(k) are free of the 10% penalty. Income tax still applies. It does not cover IRAs or 401(k)s from earlier employers.
Why did my plan only withhold 20%?
Plans must withhold 20% for federal tax on cash distributions that could have been rolled over. That is a prepayment, not the final bill. Your actual tax plus any penalty is settled on your tax return, so you may owe more or get some back.
Are hardship withdrawals penalty-free?
Not automatically. A hardship withdrawal lets you take money out while still employed, but the 10% penalty still applies before 59½ unless the reason also matches an IRS exception, such as disability or medical expenses above 7.5% of income.
How much growth do I lose by cashing out?
Money left invested keeps compounding. At a 7% yearly return, $25,000 withdrawn at age 40 could grow to about $136,000 by 65. The calculator compares that future value with the cash you keep after penalty and taxes.
Does this apply to Roth 401(k) money?
Not fully. Roth contributions come out tax- and penalty-free, but the earnings part of an early, non-qualified Roth withdrawal is taxed and penalized. This calculator assumes a traditional pre-tax 401(k).
