How to use these numbers
Each calculator gives a fair estimate from the official tables. Your real figure depends on your full tax return, so treat the result as a starting point for a conversation, not a decision.
- They work together. A required withdrawal adds to your income, which can raise your Medicare premiums and the tax on your Social Security. Each result links to the next calculator.
- Private. Your figures stay on your screen. Nothing is stored or sent.
- General information, not advice. Estimates use 2026 figures from the IRS and Medicare.
Estimates for general information only, not tax advice.
