1. What is the ADP Payroll Calculator?

The ADP Payroll Calculator helps estimate net pay after deductions including federal tax, state tax, and FICA contributions. It provides a quick way to understand take-home pay from gross salary.

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)
• \( State\ Tax \) — State income tax withholding (USD)
• \( FICA \) — Social Security and Medicare taxes (USD)

Explanation: The equation subtracts all mandatory deductions from gross pay to determine the employee's take-home pay.

3. Importance of Payroll Calculation

Details: Accurate payroll calculation ensures proper tax withholding, compliance with labor laws, and correct employee compensation.

4. Using the Calculator

Tips: Enter all amounts in USD. Values must be positive numbers. For annual calculations, use yearly figures for all inputs.
