📘 About the RMD Calculator

Required minimum distributions (RMDs) are the smallest amounts you must withdraw each year from traditional IRAs, 401(k)s and similar accounts. They start in the year you turn 73 if you were born from 1951 to 1959, and at 75 if born in 1960 or later.

Each year's RMD is last 31 December's balance divided by the factor for your age in the IRS Uniform Lifetime Table — 26.5 at 73, 24.6 at 75 and 12.2 at 90. RMDs are taxed as ordinary income; missing one costs a 25% excise tax.

❓ Frequently asked questions

At what age do RMDs start?

73 for people born 1951–1959 and 75 for people born in 1960 or later. Your first RMD can be delayed to 1 April of the next year.

How is an RMD calculated?

Divide the account balance on 31 December of the previous year by the IRS life-expectancy factor for your age. At 74 that is 25.5, so $500,000 ÷ 25.5 = $19,608.

What if I miss an RMD?

The penalty is 25% of the amount not taken, cut to 10% if you correct it within two years.

Can I give my RMD to charity?

Yes, from age 70½ a qualified charitable distribution from an IRA counts towards the RMD and is not taxed.
