Calculate a U.S. required minimum distribution from a prior December 31 retirement-account balance. The projection shows how withdrawing only the calculated RMD at year-end could affect later distributions and balances.
How to use this calculator
Check the distribution year, prior year-end account balance, and applicable beneficiary assumptions before calculating. Compare the amount with distributions already taken for that year. Account types and exceptions can change which rules apply; use the rule notes and sources below.
Examples
Age 75 in 2026
A person born in 1951 is age 75 in 2026. The Uniform Lifetime Table period is 24.6, so a $300,000 balance produces an RMD of $12,195.12.
Formula
RMD = prior December 31 balance ÷ distribution period. The projection grows the balance for the year and then subtracts that year's RMD: ending balance = beginning balance × (1 + return) − RMD.
Table selection and limits
The calculator uses the Uniform Lifetime Table unless the entered spouse is both the sole beneficiary and more than 10 years younger, in which case it uses the Joint and Last Survivor Table. That rule and the tables are in IRS Publication 590-B; the IRS RMD FAQ explains account aggregation. This tool does not handle inherited accounts, annuity adjustments, first-year deadline choices, employer-plan still-working exceptions, or corrective distributions.
