How this works

Once you reach your required beginning age, the IRS makes you withdraw a minimum amount from pre-tax retirement accounts each year. Your RMD equals your prior year-end balance divided by a life-expectancy factor from the IRS Uniform Lifetime Table — the factor shrinks as you age, so RMDs claim a larger slice of the balance over time.

Under SECURE 2.0, RMDs now begin at age 73 if you were born between 1951 and 1959, and age 75 if you were born in 1960 or later. (Those born in 1950 or earlier began at 72.) This tool grows your balance to that age, then projects each year’s RMD and the tax at your marginal rate.

Important details & exceptions

Roth IRAs have no RMDs during the owner’s lifetime, and beginning in 2024 neither do Roth 401(k)s. A still-working exception can delay 401(k) RMDs (not IRAs) if you don’t own 5%+ of the company. If your sole beneficiary is a spouse more than 10 years younger, you use the more favorable Joint Life table (lower RMDs) — this tool uses the standard Uniform Lifetime table. Qualified Charitable Distributions let those 70½+ send a six-figure amount per year (indexed) straight to charity to satisfy RMDs tax-free. Missing an RMD triggers a 25% penalty (10% if corrected promptly).

Want to soften future RMDs?

Roth conversions in your early retirement years can shrink the pre-tax balance that drives RMDs. An advisor can help you plan the timing.
