Introduction
Taking money out of your 401(k) before retirement can cost you more than you think. The IRS treats 401(k) withdrawals as regular income, so you owe federal and state taxes on every dollar you take out. If you are under age 59½, you may also owe a 10% early withdrawal penalty on top of those taxes.1
This free 401(k) withdrawal calculator shows you exactly how much you will lose to taxes and penalties, and how much cash you will actually receive. Enter your 401(k) balance, the amount you want to withdraw, your age, your income, and your state. The calculator does the rest. It breaks down your federal tax, state tax, and any early withdrawal penalty so there are no surprises.
Use the results to decide if a 401(k) early withdrawal is worth it or if you should explore other options first.
How to Use Our 401(k) Withdrawal Calculator
Enter a few details about your 401(k) account, your age, and your tax situation. The calculator will show you how much money you actually take home after federal taxes, state taxes, and any early withdrawal penalties.
Current 401(k) Balance: Enter the total amount of money in your 401(k) account right now.
Withdrawal Amount: Enter the amount you plan to take out. This must be equal to or less than your current balance.
Your Current Age: Enter your age today. If you are under 59½, the IRS charges a 10% early withdrawal penalty.1 If you are exactly 59, check the box to confirm whether you have reached 59½.
Tax Filing Status: Pick how you file your federal taxes: Single, Married Filing Jointly, Married Filing Separately, or Head of Household. This affects which tax brackets apply to your withdrawal.
Other Annual Taxable Income: Enter your total taxable income for this year, not counting the 401(k) withdrawal. The calculator stacks your withdrawal on top of this income to find the correct tax amount.
Federal Tax Method: Choose "Auto" to let the calculator use 2026 federal tax brackets based on your income and filing status. Choose "Manual" if you want to type in a flat federal tax rate yourself.
State of Residence: Pick the state where you live. The calculator fills in that state's approximate income tax rate for you.
State Income Tax Rate: This is auto-filled when you pick a state, but you can change it if you know your exact rate. States with no income tax will show 0%.
Penalty Exceptions: If you are under 59½, check any boxes that apply to you. These are special IRS rules that let you skip the 10% early withdrawal penalty.1 Examples include the Rule of 55, permanent disability, or a Qualified Domestic Relations Order.
What Is a 401(k) Withdrawal?
A 401(k) is a retirement savings account that many employers offer. The money you put in grows over time without being taxed right away, benefiting from compound interest year after year. But when you take money out, you owe taxes on it. This is called a withdrawal.
How Taxes Work on 401(k) Withdrawals
When you withdraw money from your 401(k), the IRS treats it as regular income. That means it gets added to whatever else you earned that year. You will owe federal income tax on the full amount. If your state has an income tax, you will owe that too. The exact tax you pay depends on how much you earn, your filing status, and where you live.
The 10% Early Withdrawal Penalty
If you take money out before age 59½, the IRS charges an extra 10% penalty on top of your regular taxes.1 This penalty exists to discourage people from spending their retirement savings too early. For example, if you withdraw $50,000 before age 59½, you could owe $5,000 just in penalties, and that is before any taxes.
Exceptions That Waive the Penalty
There are a few cases where the IRS will not charge the 10% penalty, even if you are under 59½. These include:
- Rule of 55: You left your job at age 55 or older.1
- Permanent disability: You are permanently unable to work.1
- SEPP (72(t) payments): You set up a schedule of equal payments over your life expectancy.6
- High medical bills: You have medical expenses that are more than 7.5% of your adjusted gross income.1
- QDRO: A court order splits your 401(k) in a divorce.1
- Death: A beneficiary inherits the account.1
Even when the penalty is waived, you still owe income taxes on the withdrawal.
