This is the simple owner-style table check. Current rules generally start RMDs at age 73, and inherited accounts, a spouse more than 10 years younger, Roth owner rules, first-year timing, account aggregation, penalties, and taxes need separate review.

Formula steps

  1. Use the account balance from the prior December 31.
  2. Use your age on your birthday in the distribution year.
  3. Look up that age in the IRS Uniform Lifetime Table.
  4. Divide the balance by the table factor.

How to use the RMD Calculator

  1. Enter the account balance from the prior December 31. For a 2026 estimate, that usually means the December 31, 2025 balance.
  2. Enter your age on your birthday in the distribution year.
  3. Calculate, then compare estimated RMD, Uniform table factor, age used, and balance after RMD.
  4. Check IRS rules, your custodian statement, inherited-account status, spouse age rules, account aggregation, withholding, penalties, and first-year timing before acting.

Frequently asked questions

Plain-language answers about when to use the estimate, what your numbers mean, what is left out, and how privacy works.

When should I use the RMD Calculator?

Use it when you want to test the exact inputs on this page: Estimate an annual RMD from a traditional IRA or similar retirement account. Look up the IRS Uniform Lifetime Table factor for one age. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.

What do the main RMD Calculator inputs mean?

Prior Dec. 31 balance means the account balance at the end of the year before the distribution year. For a 2026 RMD, that usually means the December 31, 2025 balance. Age this year means your age on your birthday in the distribution year. The table factor is picked from that age, not from your age on the day you type the estimate.

What is the RMD Calculator doing with my numbers?

In plain language: The calculator takes the prior December 31 account balance and divides it by the IRS Uniform Lifetime Table factor for the age entered. For a 2026 owner-style estimate, use the December 31, 2025 balance, choose the age you turn in 2026, then divide by that table factor.

How should I read the RMD Calculator answer?

Estimated RMD is the minimum withdrawal estimate from the entered balance. Uniform table factor is the IRS denominator. Balance after RMD is only subtraction, not a year-end prediction after market changes or taxes.

What does this estimate leave out?

This is a simple owner-style Uniform Lifetime Table estimate. It does not cover inherited IRAs, a spouse more than 10 years younger who is the sole beneficiary, Roth IRA owner rules, multiple account aggregation, first-year deadlines, penalties, tax withholding, or tax advice. Check IRS Publication 590-B, IRS RMD FAQs, your custodian statement, tax withholding, aggregation rules, and first-year timing before treating the estimate as your real required withdrawal.

What should I double-check before copying the result?

Check the balance date, the age used for the distribution year, whether the account is inherited, and whether your spouse is the sole beneficiary and more than 10 years younger.

Does this use the 2026 IRS RMD table?

It uses the IRS Uniform Lifetime Table factors shown in Publication 590-B for owner-style lifetime distributions. For example, age 75 uses factor 24.6, age 80 uses 20.2, and age 90 uses 12.2.

Can I use this for an inherited IRA RMD?

No. Inherited IRA rules can use different tables, 10-year rules, spouse rules, and beneficiary dates. Use this page only for the simple owner-style Uniform Lifetime Table estimate.

Why does the calculator allow age 72?

The IRS table still has an age 72 row, but the current general RMD starting age is usually 73. Use age 72 only if your account paperwork or tax professional says that row applies to your situation.

Does the site save my finance inputs?

No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
