1. What is Payroll Calculation?

Payroll calculation determines an employee's net pay by subtracting various deductions (taxes, insurance, retirement contributions) from their gross pay. In California, this includes federal tax, state tax, and FICA contributions.

2. How Does the Calculator Work?

The calculator uses the payroll equation:

Where:

• \( Gross\ Pay \) — Total earnings before deductions (USD/year)
• \( Federal\ Tax \) — Federal income tax withholding (USD)
• \( California\ State\ Tax \) — State income tax withholding (USD)
• \( FICA \) — Social Security and Medicare taxes (USD)

Explanation: The equation accounts for all mandatory deductions to determine take-home pay.

3. Importance of Accurate Payroll Calculation

Details: Proper payroll calculation ensures compliance with tax laws, accurate employee compensation, and proper tax reporting. Errors can lead to penalties or employee dissatisfaction.

4. Using the Calculator

Tips: Enter all values in USD. Gross pay should be annual amount. Deductions should be the amounts withheld for each category.
