The RMD on $450,000 at 83
Divide the balance on December 31 of last year by the IRS Uniform Lifetime divisor for the age you reach this year: $450,000 ÷ 17.7 = $25,423.73, which is 5.65% of the account. You turn 83 in 2026 (born 1943), and your RMDs started at 70½, so the 2026 amount is due by December 31, 2026.
| Taken | Each payment | Payments |
|---|---|---|
| Once a year | $25,423.73 | 1 |
| Quarterly | $6,355.93 | 4 |
| Monthly | $2,118.64 | 12 |
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 83
Starting with $450,000 at 83 and a 5% return after each RMD comes out. The share you must take rises every year, from 5.65% now to 9.26% at 92.

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 92.
| Return | RMDs paid over ten years | RMD at 92 | Balance after ten years |
|---|---|---|---|
| 0% | $238,332 | $21,599 | $211,668 |
| 3% | $272,017 | $28,181 | $284,463 |
| 5% | $297,588 | $33,507 | $344,784 |
| 7% | $325,964 | $39,708 | $416,382 |
Tax on an RMD of $25,424
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 83 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.
| Household | Tax the RMD adds | Share of the RMD | RMD after that tax |
|---|---|---|---|
| Single, $24,000 of Social Security | $868 | 3% | $24,556 |
| Married, $42,000 of Social Security | $0 | 0% | $25,424 |
Giving it to charity instead
A qualified charitable distribution of the full $25,424 from an IRA straight to a charity satisfies this RMD and keeps it out of taxable income, because it is under the 2026 limit of $111,000. Giving half, $12,712, leaves $12,712 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.

The calculator, set to $450,000 at 83
Set to someone born in 1943, who turns 83 in 2026, with $450,000 on December 31. Change the balance, the birth year or a planned QCD; the tax part takes your Social Security, other income and state.
Born in 1943, you are 83 in 2026, so the IRS divisor is 17.7. Your 2026 required minimum distribution from a $450,000 balance is $25,423.73, due by December 31, 2026.
An RMD is income, so it can move your Medicare premium two years later. Add this RMD in the IRMAA calculator.
With $24,000 of Social Security and $20,000 of other income, filing single, your $25,424 taxable RMD adds about $4,753 of federal tax, 18.7% of it. That is the difference between your tax with and without the RMD, on 2026 brackets.
