Summary
Enter a gross wage and pay frequency to see your Social Security, Medicare, and Additional Medicare Tax withholding for the year.
How it works
- Enter the gross wage amount and select the pay frequency it represents.
- The calculator projects an annual gross wage from that frequency.
- It applies 6.2% Social Security tax up to the annual wage base, stopping once the base is reached.
- It applies 1.45% Medicare tax to all wages, with no cap.
- Wages above $200,000 in the year get an extra 0.9% Additional Medicare Tax on the amount over that threshold.
- Results show both the per-period withholding and the full-year totals.
Use cases
- Estimate take-home pay after Social Security and Medicare withholding.
- Check whether a raise pushes you into the Additional Medicare Tax range.
- Verify a pay stub's FICA line items against an independent calculation.
- Compare FICA withholding across different pay frequencies.
- Estimate the employer's matching FICA cost for a given salary.
- Plan year-end income once the Social Security wage base has been reached.
