RMD at Age 88 — IRS Distribution Factor & 2026 Calculator
What is the Required Minimum Distribution for a 88-year-old?
At age 88, the IRS Uniform Lifetime Table assigns a distribution period of 13.7 years. This means your Required Minimum Distribution equals your December 31 prior-year account balance divided by 13.7. On a $500,000 account, the RMD is approximately $36,496 — about 7.3% of the account value.
At age 88, the distribution factor is 13.7 years, producing an RMD of approximately $36,496 on a $500,000 balance — about 7.30%. At these distribution rates, heirs and beneficiaries should understand the inherited IRA 10-year distribution rule that will apply after the account owner's death.

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.
