About the Medicare Tax Calculator
The Medicare Tax Calculator gives you an instant answer from just a few inputs — annual wages, filing status. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
Unlike Social Security tax, Medicare tax has no wage cap — the 1.45% applies to every dollar you earn. High earners face an extra layer: an Additional Medicare Tax of 0.9% kicks in above $200,000 ($250,000 for joint filers), which employers withhold but don't match. This surtax is calculated on your return, so if you have multiple jobs, too little may be withheld and you could owe the difference at filing.
