1. What is Net Pay Calculation?

The net pay calculation determines your take-home pay after all deductions including federal tax, state tax, FICA (Social Security and Medicare), and 401k contributions. This is especially important for California residents due to the state's specific tax rates.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Gross\ Pay \) — Total annual salary before deductions
• \( Federal\ Tax \) — Estimated federal income tax
• \( California\ State\ Tax \) — California state income tax
• \( FICA \) — Social Security and Medicare taxes (7.65% of gross pay typically)
• \( 401k \) — Retirement contribution (percentage of gross pay)

Explanation: The equation accounts for all major deductions from your gross salary to determine your actual take-home pay.

3. Importance of Salary Calculation

Details: Accurate net pay calculation helps in financial planning, budgeting, and understanding how different retirement contributions affect your take-home pay.
