Calculate your RMD
Estimates use 2026 IRS brackets, standard and senior deductions, the Social Security worksheet and the 2026 Medicare Part B premium of $202.90 with IRMAA tiers. Medicare sets IRMAA from your return two years back, so use this as a planning guide. It excludes capital gains rates, state tax, Part D surcharges, credits and itemized deductions. Not tax advice.

How your retirement income is taxed and what Medicare adds

Short answer: your Social Security, pension and IRA withdrawals feed one tax calculation. The same income also decides whether you pay extra for Medicare Part B. Seeing both at once shows what you really keep.

When Social Security becomes taxable

The IRS adds half of your Social Security to all your other income, including tax-exempt interest. That total is called combined income. Compare it to these thresholds.

Combined incomeSingleMarried filing jointlyShare of benefits taxable
Below the first thresholdUnder $25,000Under $32,0000%
Between thresholds$25,000 to $34,000$32,000 to $44,000Up to 50%
Above the second thresholdOver $34,000Over $44,000Up to 85%

These thresholds are not adjusted for inflation, so more retirees cross them every year. See our Social Security taxability guide for the full worksheet.

The income used is your adjusted gross income plus tax-exempt interest, taken from your return two years earlier. Part D drug plans add their own surcharge, which this tool does not include. If your income dropped because of retirement, you can appeal. See our IRMAA appeal guide.

What this calculator leaves out

It estimates federal income tax and the Medicare Part B premium only. State tax, capital gains rates, Part D surcharges, the net investment income tax, itemized deductions and credits are not included. For state rules see our state retirement tax guide. For federal tax alone, use the retirement tax estimator.

Frequently asked questions

How much of my retirement income do I keep after taxes and Medicare?
Add your Social Security, pension, IRA withdrawals and other income to the calculator. It subtracts 2026 federal income tax and your Medicare Part B premium, including any IRMAA surcharge, and shows what is left each month.
What is the IRMAA surcharge?
IRMAA is an extra charge on Medicare Part B and Part D premiums for higher earners. For 2026 it starts above $109,000 of income for a single filer and $218,000 for a married couple. Medicare looks at your tax return from two years earlier.
Does my IRA withdrawal raise my Medicare premium?
It can. IRA withdrawals and RMDs count as income. If they push your income past an IRMAA threshold, you pay the full surcharge for that tier, so one extra dollar can cost hundreds or thousands.
Is Social Security counted in the IRMAA income?
Only the taxable part. IRMAA uses your adjusted gross income plus tax-exempt interest, so the untaxed share of your Social Security is left out.
Does this calculator include state tax?
No. It covers federal tax and Medicare Part B only. If you pick a state with no income tax, it tells you so. Other states vary a lot, so see our state retirement tax guide.
