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

  1. Enter the gross wage amount and select the pay frequency it represents.
  2. The calculator projects an annual gross wage from that frequency.
  3. It applies 6.2% Social Security tax up to the annual wage base, stopping once the base is reached.
  4. It applies 1.45% Medicare tax to all wages, with no cap.
  5. Wages above $200,000 in the year get an extra 0.9% Additional Medicare Tax on the amount over that threshold.
  6. 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.
