401(k) Early Withdrawal Calculator

Three things stack up. First, a 10% federal early-withdrawal penalty on the gross amount if you are under age 59.5. Second, ordinary federal income tax at your marginal rate (commonly 22% or 24%) because the distribution counts as taxable income. Third, state income tax if your state taxes wages. On a $10,000 withdrawal at a 22% federal marginal rate and a 5% state rate, that is $1,000 in penalty, $2,200 in federal tax, and $500 in state tax, for $3,700 in total and roughly $6,300 in your pocket.

The 20 percent mandatory withholding rule generally applies to an eligible rollover distribution paid to you instead of transferred directly to another eligible plan or IRA. It does not apply identically to every withdrawal, and other nonperiodic payments can use different withholding rules. Withholding is a tax prepayment, not the final tax or the separate 10 percent additional tax. Check the plan's distribution notice or a tax professional for the payment you are considering.

A plan's hardship-withdrawal rules and the tax-code exceptions to the 10 percent additional tax are separate. A distribution may qualify as a plan hardship and still owe the additional tax. Exceptions can include certain medical expenses, disability, qualified birth or adoption distributions, qualified domestic relations orders, IRS levies, and separation from service in or after the year you turn 55, subject to detailed requirements. The calculator's toggle is a generic scenario switch; verify that a specific statutory exception applies before setting the penalty to zero.

Because compounding runs for decades. $10,000 left invested at a 7% annual return grows to roughly $54,300 over 25 years. That is the long-term retirement money you give up by cashing out today, on top of the $3,700 in immediate taxes and penalties on a 22% federal, 5% state withdrawal. For most people in their 30s and 40s, the opportunity cost is by far the biggest line item in a 401(k) early withdrawal.

A plan loan can avoid current tax if it meets the plan and tax rules and you repay it on schedule, but it adds repayment, investment, and job-change risk. Plan terms determine what happens after employment ends. An unpaid balance may become a taxable distribution or plan-loan offset, and some qualifying offsets can be rolled over by the applicable tax-return deadline. Review the plan document before comparing it with a withdrawal.
