Minnesota 401(k) and IRA Divorce Calculator (2026)
What Is Your Retirement Account Really Worth?
A $150,000 IRA or 401(k) is not worth $150,000 the way home equity or cash in the bank is. Income tax comes out before you can spend it, and sometimes a 10% penalty too. See what a pre-tax account is worth if you cash it out now, and what it is worth if you keep it until retirement.
The account
The number on the latest statement, before any taxes.
Work plans are split with a QDRO, a court order the plan has to follow.
About you
Before taxes. Leave this account out.
Head of household usually means a child lives with you more than half the year. If your divorce is final by December 31, you file as unmarried for that whole year.
Retirement
Count everything you will live on: Social Security, pensions and withdrawals from all your retirement accounts, including this one.
The pre-tax value of this account is $150,000. After taxes, it is really worth
What lands in your bank account if you cash it out this year, after federal tax, Minnesota tax and any penalty.
What it is worth after taxes, in today’s dollars, if you leave it alone until retirement.
Does not include any market increase or decrease in value.
Roth money is already taxed. Once you are 59½ and the account has been open five years, withdrawals are tax-free, so it is worth its full balance.
Cashing out a Roth early is different. The money that went in comes out tax-free, but the earnings are taxed and usually get the 10% penalty. A Roth 401(k) paid to a spouse straight from the plan under a QDRO skips the penalty, but not the tax on earnings. The statement shows how much of the balance is contributions.

How this estimate works
Taxes use the 2026 federal and Minnesota brackets and standard deductions. The cash-out tax is your tax with the withdrawal minus your tax without it, so a big withdrawal climbs through the brackets. It assumes no itemized deductions and no tax credits. Credits like the child tax credit can shrink when income jumps, which would make cashing out cost more.
The Keep-It Value is in today’s dollars and leaves out market gains and losses. To estimate the size of your yearly withdrawals in retirement, it assumes 6% yearly growth, 2.5% inflation, even withdrawals from retirement to age 90, single filing and today’s brackets, which rise with inflation. It treats all of your retirement income as taxable. Tax laws change.
A SIMPLE IRA less than two years old carries a 25% penalty instead of 10%. This calculator does not value pensions that pay a monthly check.
