That is what this withdrawal could have grown to if left invested. Every $1 pulled out today costs about 5.8 of future retirement money.
Plan administrators withhold 20% ($2,000) up front as estimated federal tax. That withholding counts toward the federal income tax shown above, not on top of it.
Frequently Asked Questions about the 401(k) Early Withdrawal Calculator
What does a 401(k) early withdrawal actually cost?
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.
What is the 20% mandatory federal withholding?
Federal rules require your plan administrator to withhold 20% of an eligible 401(k) distribution and send it to the IRS as estimated tax. That is not an extra tax on top of your marginal rate; it is a prepayment toward the income tax you already owe. If your marginal bracket is 22%, you still owe a true 22% in federal income tax, and the 20% withholding counts toward that bill at filing time. You true up the remainder (or get a small refund) on your tax return.
What hardships waive the 10% early-withdrawal penalty?
The IRS allows several exceptions: total and permanent disability, unreimbursed medical bills above 7.5% of AGI, separation from service in or after the year you turn 55, qualified domestic relations orders, IRS levies, certain qualified birth or adoption distributions (up to $5,000), and a few disaster-relief carve-outs. Toggle the hardship exception in the calculator to zero out the 10% penalty. Income tax still applies in every case.
Why is the opportunity cost so much larger than the taxes?
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.
Is a 401(k) loan a better option than an early withdrawal?
Usually yes, if your plan allows it and you stay employed. A 401(k) loan lets you borrow up to the lesser of $50,000 or 50% of your vested balance and pay yourself back with interest, with no 10% penalty and no income tax as long as you repay on schedule. The catch: if you leave or lose your job, the outstanding balance often becomes a deemed distribution, which triggers both the income tax and the 10% penalty. Run those numbers in this calculator before deciding.
