1. What is Net Pay Calculation?

The net pay calculation determines take-home salary after deducting all mandatory taxes and contributions from gross pay. In California, this includes federal tax, state tax, and FICA (Social Security and Medicare) contributions.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Gross\ Pay \) — Total earnings before deductions (USD/year)
