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.

Key RMD Rules

  • 1IRS distribution factor at age 90: 12.2 years.
  • 2RMD formula: December 31 prior-year balance ÷ 12.2.
  • 3On a $500,000 account, this produces an RMD of approximately $40,984.
  • 4Deadline: December 31 of the current year (or April 1 of the following year for your very first RMD only).
  • 5The 25% penalty for missing an RMD (reduced to 10% if corrected within the correction window) applies regardless of age.
  • 6At 8%+ distribution rates, focus shifts to income planning and ensuring distributions are coordinated with Social Security, pension, and other income.

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.
