What this planner proves as it calculates

  • RMD Compass computes RMDs using all 49 age factors of the IRS Uniform Lifetime Table in effect since 2022 (Pub 590-B, Table III), and shows the factor used for every result.
  • All calculations run in your browser. Balances and ages are never transmitted or stored — there is no account, login, or email wall.
  • The planner displays 2026 IRMAA MAGI thresholds next to your projected income for every year of your plan, so Roth conversions can be sized under the next Medicare surcharge cliff.
  • Multi-year view models RMDs and Roth conversions together on one timeline through age 100+.
  • Every figure carries its IRS source citation inline; the constants file with source URLs is published on the methodology page.
  • Unit tests reproduce IRS Publication 590-B worked examples to the cent; the test cases are listed publicly.

Plain-language answers

RMD questions

When do I have to take my first RMD?

Your first RMD is generally due for the year you reach your applicable age: 73 for people born 1951–1959 and 75 for people born in 1960 or later. You may delay that first payment until April 1 of the next year, but doing so can put two RMDs in one tax year. Source: IRS retirement topics — RMDs.

What happens if I miss an RMD?

The excise tax is generally 25% of the amount not taken. It can fall to 10% when the shortfall is corrected within the applicable correction window, so document the correction and consult a tax professional promptly. Source: IRS retirement topics — RMDs.

Do Roth IRAs have RMDs?

A Roth IRA has no lifetime RMD for its original owner. Designated Roth accounts in 401(k) and 403(b) plans have also been exempt from pre-death RMDs since the 2024 tax year, though beneficiary rules still apply after death. Source: IRS retirement topics — RMDs.

Can I convert my RMD to a Roth?

No. The full RMD must be satisfied first because an RMD is not eligible for rollover or Roth conversion. Only additional eligible dollars can be converted afterward. Source: IRS Publication 590-A.

What is IRMAA and why does my 2026 income matter in 2028?

IRMAA is an income-related surcharge added to Medicare Part B and Part D premiums. Social Security generally uses tax-return MAGI from two years earlier, so a threshold crossed with 2026 income can affect 2028 Medicare premiums. Source: Social Security — IRMAA.

Is my data stored?

No. Every calculation runs in your browser. This site has no account, login, email form, or server-side storage for what you enter. Source: RMD Compass methodology.
