A required minimum distribution, commonly called an RMD, is the minimum amount an eligible retirement account owner generally must withdraw for a particular calendar year after reaching the applicable starting age.
RMD rules commonly apply to traditional IRAs, SEP IRAs, SIMPLE IRAs and many employer-sponsored retirement plans. Different treatment may apply to Roth accounts, inherited accounts and workplace plans when the participant is still employed.
Basic RMD formula
The general calculation divides the retirement account balance from the previous December 31 by the applicable IRS distribution period.
Required minimum distribution = previous year-end balance ÷ applicable life-expectancy factor
Which balance should you enter?
Enter the account value from December 31 immediately before the distribution year. For example, an estimated 2026 RMD generally begins with the applicable account balance from December 31, 2025.
Which IRS table normally applies?
- The Uniform Lifetime Table generally applies to retirement account owners calculating their own RMD.
- The Joint and Last Survivor Table generally applies when the spouse is the sole beneficiary and is more than 10 years younger.
- The Single Life Expectancy Table may apply to certain beneficiaries and inherited retirement accounts.
