1. What is Post-Tax Salary Calculation?

The post-tax salary calculation determines your actual take-home pay after deducting all mandatory taxes and contributions. In California, this includes federal tax, state tax, and FICA contributions.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Gross\ Pay \) — Total earnings before any deductions
• \( Federal\ Tax \) — Federal income tax withholdings
• \( California\ State\ Tax \) — State income tax withholdings
• \( FICA \) — Social Security and Medicare taxes

Explanation: The equation subtracts all mandatory deductions from your gross salary to determine your actual take-home pay.

3. Importance of Net Pay Calculation

Details: Understanding your net pay helps with budgeting, financial planning, and comparing job offers. California has some of the highest state taxes in the US, making accurate calculations particularly important.

4. Using the Calculator

Tips: Enter your gross annual salary and estimated tax amounts. For ADP users, these values can typically be found on your pay stub or in the ADP portal.
