401(k) Early Withdrawal Calculator

Tapping retirement savings early is expensive: a 10% penalty plus ordinary income tax. Enter the amount and your tax rate to see the penalty, the tax, and the net you'd actually walk away with — usually far less than the balance you gave up.

How this calculator works

Penalty = withdrawal × 10%. Income tax = withdrawal × your marginal rate (it's taxed as ordinary income). Net received = withdrawal − penalty − tax. Share kept is net ÷ withdrawal.

Uses the standard 10% federal penalty and a single marginal rate you provide; include state income tax in that rate for a fuller picture. It doesn't model penalty exceptions or the lost future growth — the FAQ covers both, and the growth is usually the largest hidden cost.

What this assumes

  • A 10% early-withdrawal penalty plus income tax at the marginal rate you enter. Several exceptions exist — disability, certain medical costs, separation from service at 55 — and none are applied automatically here.
  • Mandatory 20% federal withholding applies to most plan distributions, which is a prepayment rather than the final bill.
  • The lost future growth shown assumes the money would have stayed invested at your expected return until retirement.

What changes this number

The lost compounding
Almost always larger than the tax and penalty combined, and the part that does not appear on any statement.
Your marginal rate
The withdrawal stacks on top of your other income, so a large one can push part of itself into a higher bracket.
Whether an exception applies
Worth checking before withdrawing rather than after — the exceptions are specific and several are commonly missed.

Frequently asked questions

What is the penalty for withdrawing from a 401(k) early?

Withdrawals before age 59½ generally incur a 10% early-withdrawal penalty on top of ordinary income tax. On a $20,000 withdrawal in the 22% bracket, that's a $2,000 penalty plus $4,400 in tax — you keep only about $13,600 of the $20,000, before any state tax.

Are there exceptions to the 10% penalty?

Yes — the IRS waives the penalty for certain situations like total disability, some medical expenses, a first home (IRAs, up to limits), higher-education costs (IRAs), and separation from service at 55+ (401(k)s). Income tax still applies. The rules are specific, so confirm eligibility with a tax professional.

Why is an early withdrawal so costly beyond the penalty?

The biggest cost is invisible: the future growth you give up. Money pulled out today stops compounding for decades, so a $20,000 withdrawal at 35 can cost well over $150,000 in retirement value. The penalty and tax are just the upfront hit — the lost compounding is the real expense.

What are alternatives to an early withdrawal?

Consider a 401(k) loan (you repay yourself, no penalty if repaid on time), a hardship withdrawal if you qualify, or tapping non-retirement savings first. For debt, a personal loan or balance transfer may cost less than the penalty plus tax plus lost growth. Cashing out retirement should be a last resort.
