RMD on $2.5 million at 78

The 2026 required minimum distribution on a $2.5 million IRA or 401(k) at age 78 is $113,636.36. Below: how it is worked out, when it is due, the next ten years, the federal tax it adds and a calculator set to $2.5 million at 78.

Short answer: $113,636.36 for 2026, or about $9,470 a month: the December 31 balance of $2,500,000 divided by the IRS divisor for age 78, 22.0. That is 4.55% of the account.

The RMD on $2.5 million at 78

Divide the balance on December 31 of last year by the IRS Uniform Lifetime divisor for the age you reach this year: $2,500,000 ÷ 22.0 = $113,636.36, which is 4.55% of the account. You turn 78 in 2026 (born 1948), and your RMDs started at 70½, so the 2026 amount is due by December 31, 2026.

The total only has to be out by the deadline; how often you take it is up to you and the custodian. Withholding federal tax from the RMD counts as paying it, and tax withheld late in the year is treated as paid evenly through it.

The next ten years from 78

Starting with $2.5 million at 78 and a 5% return after each RMD comes out. The share you must take rises every year, from 4.55% now to 6.94% at 87.

What the return changes

The RMD is a share of whatever the account holds, so the return decides how much comes out over the decade and what is left at 87.

Tax on an RMD of $113,636

An RMD from a traditional IRA or 401(k) is ordinary income, and it can make more of your Social Security taxable. Estimated federal tax it adds at 78 on 2026 brackets, with the standard deduction, the 65-and-older amount and the senior deduction. Most states add their own tax; the retirement tax calculator includes it.

Giving it to charity instead

Up to $111,000 can go from an IRA straight to a charity in 2026 as a qualified charitable distribution, counted toward this RMD and kept out of taxable income. That covers 98% of the $113,636 RMD; the other $2,636 stays taxable. QCDs are open from 70½, come only from IRAs (not 401(k)s), and have to be paid to the charity directly. A Roth conversion done before RMDs begin is the other way to shrink them: see the Roth conversion calculator.
