1. What is Net Pay Calculation?

The net pay calculation determines an employee's take-home pay after deducting all required taxes and contributions from their gross pay. This calculator specifically calculates net pay for Illinois employees.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

Explanation: The calculation subtracts all mandatory deductions from the gross pay to determine the actual amount the employee will receive.

3. Importance of Accurate Salary Calculation

Details: Accurate net pay calculation is essential for both employers and employees to understand take-home pay, budget effectively, and ensure proper tax withholding.
