RMD at Age 90 — IRS Distribution Factor & 2026 Calculator
What is the Required Minimum Distribution for a 90-year-old?
At age 90, the IRS Uniform Lifetime Table assigns a distribution period of 12.2 years. This means your Required Minimum Distribution equals your December 31 prior-year account balance divided by 12.2. On a $500,000 account, the RMD is approximately $40,984 — about 8.2% of the account value.
At age 90, the IRS factor is 12.2 years, requiring approximately $40,984 from a $500,000 balance — about 8.20% annually. At this distribution rate, the primary purpose of the IRA has shifted fully to income generation rather than wealth accumulation or preservation.

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.
