Employer share of Social Security and Medicarehigh confidence
- Observed range
- 0.0145 — 0.0765 (typical 0.0765)share of wages
- Why this value
- 6.2% Social Security up to the annual wage base plus 1.45% Medicare with no cap, which is the employer half. Included in total compensation because it is a genuine cost of employment and is essential when comparing an employee role against contract work, where the worker pays both halves.
- Applies to
- Federal, so uniform. State unemployment insurance is an additional employer cost that varies by state and by the employer's claims history, and is not modeled.
- Known limits
- The wage base is indexed annually and needs checking each January. Federal and state unemployment insurance, and workers compensation, are real employer costs not included here.
