To keep a given amount from a 401(k) before 59½, you have to withdraw more than that amount, because the 10 % additional tax, federal income tax and any state tax all come out of the same payout. This calculator starts from the net you need and searches the gross withdrawal that leaves exactly that after taxes, using the 2026 brackets of Rev. Proc. 2025-32. A married couple with $55,000 of other income who need $25,000 must take about $32,000 from an old 401(k): $3,200 of penalty and $3,800 of federal tax. A single earner on $120,000 needs $37,824 for the same $25,000, and someone covered by the rule of 55 with no other income needs only $25,989. The plan then withholds 20 % of the gross, so the cash on the day of payout differs from what you keep once the return is filed.
Why a quick division misses the real gross
The quick rule people use is to divide the cash they need by one minus the 10 % and their tax bracket. For the single earner on $120,000, whose withdrawal is taxed at 24 %, that gives $37,879 for $25,000 in hand. The calculator lands at $37,824. The gap is small there because the whole withdrawal sits in one bracket. It grows when the payout crosses a bracket line or starts under the standard deduction, which is the usual case in the first year of early retirement: with no other income, the first dollars are taxed at zero, then at 10 %, then at 12 %, and the 10 % applies to all of them. The engine solves for the gross by repeating the full 2026 tax calculation until the net matches to the cent.
| Cash you need | Withdraw | 10 % tax | Federal tax | Top bracket reached | Paid out after 20 % withheld | At filing |
|---|---|---|---|---|---|---|
| $10,000 | $12,769 | $1,277 | $1,492 | 12 % | $10,215 | $215 due |
| $25,000 | $32,000 | $3,200 | $3,800 | 12 % | $25,600 | $600 due |
| $50,000 | $64,051 | $6,405 | $7,646 | 12 % | $51,241 | $1,241 due |
| $80,000 | $106,118 | $10,612 | $15,506 | 22 % | $84,894 | $4,894 due |
Read the rows from top to bottom and the cost per dollar climbs. Keeping $10,000 costs $2,769 in tax and penalty; keeping $80,000 costs $26,118, because the larger withdrawal pushes part of the couple's income from the 12 % bracket into the 22 % bracket. Two smaller withdrawals in two tax years often cost less than one large one.

The same $25,000 in five lives
The net you need is one input; your year is the other. The table below holds the target at $25,000 and changes the person.
| Situation | Withdraw | 10 % tax | Federal tax | State tax | Cost per dollar kept |
|---|---|---|---|---|---|
| Single, 51, laid off, no other income | $29,256 | $2,926 | $1,331 | $0 | 17 % |
| Joint, 46, $55,000 of other income | $32,000 | $3,200 | $3,800 | $0 | 28 % |
| Single, 44, $120,000 salary | $37,824 | $3,782 | $9,042 | $0 | 51 % |
| Same, living in Georgia (4.99 %) | $40,918 | $4,092 | $9,784 | $2,042 | 64 % |
| Single, 57, left the employer at 55 | $25,989 | $0 | $989 | $0 | 4 % |
The laid-off 51-year-old is the cheapest of the penalized cases, $29,256 for $25,000, because the standard deduction and the low brackets absorb most of the income tax; the 10 % is then the largest single cost. The high earner pays the most, and moving to a state with a flat income tax adds another $3,094 to the gross. The rule of 55 case shows what an exception is worth: with the 10 % gone, $25,989 is enough. The 401(k) withdrawal penalty page breaks down each charge.
Cash on payout day versus cash after filing
The calculator answers what you keep for the year. On the day of the payout you receive something else: the gross minus the 20 % the plan must withhold from an eligible rollover distribution paid to you (IRS Publication 575). For the couple needing $50,000, the plan pays $51,241 on a gross of $64,051: more than they need on payout day, but the extra $1,241 is owed back when the return is filed, so it should stay set aside. The laid-off 51-year-old is in the opposite position. The gross of $29,256 pays only $23,405 on the day, short of the $25,000 needed, and the difference comes back as a refund the following spring. If the full amount is needed right away, either ask for a larger gross, about $31,250 to receive $25,000 after withholding, or keep a cash buffer until filing. A larger gross raises the tax a little, so run the number again with the new amount.
From a monthly budget to one yearly figure
Most people arrive with a monthly number: $3,500 a month to cover a mortgage and groceries until a new job or until the next account opens. The tax year is what matters, so enter the twelve months together, $42,000, rather than one month at a time; the brackets and the standard deduction apply to the year, and a monthly calculation would show a lower rate than you will actually pay. If the need covers only part of the year, enter the months that fall in this calendar year and run the rest again in January with next year's other income.
The order of withdrawals across accounts can matter as much as the amount. Money from an IRA has no mandatory 20 % withholding, money from a governmental 457(b) carries no 10 % additional tax at any age apart from amounts rolled in from another plan or an IRA, and Roth IRA contributions come out free of both. Choosing a different account in the calculator shows how much each source costs for the same cash.
Before you type a number
- Pick the right account in the calculator. An old 401(k) from a former employer never qualifies for the rule of 55; the plan of the employer you leave can.
- Count all other taxable income for the year, including a spouse's wages on a joint return, unemployment pay and Roth conversions.
- Use your state's real rate. Some states exclude retirement payouts, others add a tax; the state page lists eleven.
- Roth IRA contributions come out first and owe neither tax nor penalty. Choosing "Roth IRA: your own contributions" in the account list shows the effect.
What the calculator leaves out
It assumes the whole withdrawal is pre-tax money. If part of your 401(k) is after-tax contributions, that part is neither taxed nor penalized, so the gross you need is lower. It does not apply credits, itemized deductions or the net investment income tax. It does not model a payout that changes your marketplace health premium: a larger withdrawal raises the modified adjusted gross income (MAGI) used for the premium tax credit, which the ACA subsidy page measures. And it uses the federal rules for 2026 only.
