Frequently Asked Questions about the RMD Calculator
What is a Required Minimum Distribution (RMD)?
An RMD is the minimum amount the IRS requires you to withdraw each year from most tax-deferred retirement accounts once you reach a set age. The rule applies to Traditional IRAs, SEP and SIMPLE IRAs, 401(k)s, 403(b)s, and most other employer-sponsored plans. Roth IRAs do not require lifetime RMDs from the original owner. The formula is the prior year-end account balance divided by a life expectancy factor from an IRS table.
At what age do RMDs start?
Under SECURE 2.0, RMDs now start the year you turn 73, up from age 72 before 2023. Starting in 2033 the age moves again to 75. Your first RMD has a one-time deadline of April 1 of the year after you turn 73; every later RMD must be taken by December 31. Delaying the first RMD into the following April means taking two RMDs in one tax year, which can push you into a higher bracket.
How is the RMD calculated?
RMD equals your prior year-end account balance divided by the life expectancy factor for your age from the IRS Uniform Lifetime Table. For example, at age 75 the factor is 24.6, so a $400,000 prior year-end balance yields a $400,000 / 24.6 = $16,260 RMD. The factor shrinks each year, so the required withdrawal grows as a percentage of the account over time.
Which IRS table does this calculator use?
It uses the Uniform Lifetime Table from IRS Publication 590-B, which applies to most account owners: anyone unmarried, anyone whose spouse is not more than ten years younger, and anyone whose spouse is not the sole beneficiary. If your spouse is the sole beneficiary and more than ten years younger, the IRS Joint Life Table produces a slightly larger factor and a smaller RMD; this calculator will overstate your RMD in that case.
What happens if I miss an RMD?
Missing an RMD or taking less than required triggers an IRS excise tax. SECURE 2.0 lowered the penalty from 50 percent to 25 percent of the shortfall, and it drops to 10 percent if you correct the missed withdrawal within a defined window and file Form 5329. Even with the lower penalty, the cheapest path is to take the full RMD on time. If you hold multiple IRAs, you can total the RMD across them and withdraw from any one; 401(k) and 403(b) RMDs must be calculated and taken from each plan separately.
