Estimate only. The 10% penalty applies to most withdrawals before age 59½, but exceptions exist (disability, certain medical or first‑home costs, separation from service at 55+, and others). Your actual federal tax depends on your total income for the year. This is not tax advice — confirm with a tax professional.

How to use this calculator

Enter the amount you want to withdraw, your estimated federal and state tax rates, and whether you're under age 59½. The calculator shows the income tax, the 10% early‑withdrawal penalty (if it applies), and the net amount you'd actually keep.

How a 401(k) withdrawal is taxed

A traditional 401(k) is funded with pre‑tax dollars, so the IRS taxes withdrawals as ordinary income. Three things reduce what reaches your bank account: federal income tax at your marginal rate, state income tax (zero in some states), and — if you're younger than 59½ — a 10% early‑withdrawal penalty. Together these can take a large bite out of the gross amount.

Worked example

Say you withdraw $25,000 before 59½, with a 22% federal rate and a 5% state rate. Federal tax is $5,500, state tax is $1,250, and the penalty is $2,500 — about $9,250 total, leaving roughly $15,750. Adjust the inputs above for your own situation.

This tool gives a simplified estimate and is not tax advice. Your real federal tax depends on your total annual income, and penalty exceptions may apply. Consult a tax professional before withdrawing.

Frequently asked questions

How much will I actually receive from a 401(k) withdrawal?

It depends on your tax bracket, your state, and your age. A withdrawal is added to your taxable income, so federal and state income tax apply, and if you're under 59½ there's usually an additional 10% early‑withdrawal penalty. Enter your numbers above to estimate the net amount.

What is the 10% early withdrawal penalty?

If you take money out of a traditional 401(k) before age 59½, the IRS generally charges a 10% penalty on top of regular income tax. Some exceptions waive it — such as total disability, certain medical expenses, or leaving your employer in the year you turn 55 or later.

Is a 401(k) withdrawal taxed as income?

Yes. Money from a traditional 401(k) was contributed pre‑tax, so withdrawals are taxed as ordinary income in the year you take them. A large withdrawal can push part of your income into a higher bracket, so your effective rate may differ from your top bracket.

Does my employer withhold taxes automatically?

Plans typically withhold 20% for federal taxes on eligible distributions, but that's a prepayment, not your final bill. Your actual tax is settled when you file, and the 10% penalty is usually paid then too.

How can I avoid the penalty?

Common ways to access funds without the 10% penalty include a 401(k) loan, a hardship distribution that qualifies for an exception, substantially equal periodic payments (72(t)), or waiting until 59½. A financial or tax professional can help you choose.
