How It Works
Required Minimum Distributions (RMDs) are mandatory annual withdrawals from tax-deferred retirement accounts. This calculator uses the IRS Uniform Lifetime Table to determine your distribution amount: RMD = Account Balance / Life Expectancy Factor.
The basic rule:
- RMD = Prior year-end account balance ÷ IRS life expectancy factor for your age
- RMDs begin at age 73 (for those born 1951-1959) or age 75 (born 1960+) under SECURE 2.0
- If your sole beneficiary is a spouse 10+ years younger, use the Joint Life Expectancy Table for a smaller RMD
- Failure to take your full RMD results in a 25% penalty (reduced from 50% by SECURE 2.0) on the shortfall
RMDs are taxed as ordinary income. Strategic planning — including Roth conversions before RMD age, qualified charitable distributions (QCDs), and timing withdrawals across tax years — can significantly reduce the lifetime tax impact of RMDs.
Tips & Considerations
- Double-check your account balance as of dec 31 before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both required minimum distribution and life expectancy factor — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to get accurate results.
- If you're unsure about your estimated tax bracket, start with a conservative estimate and adjust from there.
Frequently Asked Questions
When do I have to start taking RMDs?
Under SECURE 2.0: if born 1951-1959, RMDs begin at age 73. If born 1960 or later, RMDs begin at age 75. Your first RMD can be delayed until April 1 of the year after you reach the applicable age, but you will then need to take two RMDs that year (the delayed first one plus the current year's). Roth IRAs have no RMDs during the owner's lifetime.
How is the RMD calculated?
RMD = December 31 account balance of the prior year ÷ IRS life expectancy factor. For example, at age 75 the Uniform Lifetime Table factor is 24.6. If your account balance was $500,000, your RMD would be $500,000 / 24.6 = $20,325. The factor decreases each year, so RMDs as a percentage of your account grow over time.
What is the penalty for missing an RMD?
SECURE 2.0 reduced the penalty from 50% to 25% of the shortfall (the amount you should have withdrawn but did not). If you correct the error in a timely manner, the penalty drops to 10%. If you miss an RMD, file Form 5329 with your tax return and request a penalty waiver — the IRS frequently grants waivers for reasonable cause.
Can I reduce my RMDs?
Several strategies: (1) Roth conversions before RMD age reduce the traditional IRA balance. (2) Qualified Charitable Distributions (QCDs) satisfy your RMD while excluding up to $105,000 from taxable income. (3) If still working, 401(k) funds at your current employer may be exempt from RMDs. (4) Consider the timing of large Roth conversions to manage the tax impact.
