RMD at Age 91 — IRS Distribution Factor & 2026 Calculator
What is the Required Minimum Distribution for a 91-year-old?
At age 91, the IRS Uniform Lifetime Table assigns a distribution period of 11.5 years. This means your Required Minimum Distribution equals your December 31 prior-year account balance divided by 11.5. On a $500,000 account, the RMD is approximately $43,478 — about 8.7% of the account value.
At age 91, the distribution factor is 11.5 years, producing an RMD of approximately $43,478 on a $500,000 balance — about 8.70%. The IRS table continues well beyond age 91 (to age 120), with factors decreasing to as low as 2.0 at age 120.

Key RMD Rules
- 1IRS distribution factor at age 91: 11.5 years.
- 2RMD formula: December 31 prior-year balance ÷ 11.5.
- 3On a $500,000 account, this produces an RMD of approximately $43,478.
- 4Deadline: December 31 of the current year (or April 1 of the following year for your very first RMD only).

Common RMD Mistakes to Avoid
- ⚠Using the current year's balance instead of the December 31 prior-year balance — always use the prior December 31 value.
- ⚠Forgetting to take RMDs from each employer plan (401k, 403b) separately — you cannot aggregate multiple employer plans.
- ⚠Assuming the RMD percentage stays constant — it increases every year as the distribution factor decreases.
