Net Pay = Gross Pay - (Federal Tax + FICA + State Tax + Pre-Tax + Post-Tax Deductions)Calculates periodic take-home pay by subtracting mandatory federal income taxes, FICA (6.2% Social Security + 1.45% Medicare), state income taxes, and optional payroll benefits from gross earnings.

$75,000 Annual Salary Paid Bi-Weekly in California
Calculating bi-weekly net take-home pay for a single filer with $250/check pre-tax 401(k).
- Gross pay per check: $75,000 / 26 = $2,884.62.
- Pre-tax deduction (401k): $250.00 -> Taxable gross: $2,634.62.
- Estimated federal income tax: ~$268.30 per check.
- FICA: Social Security (6.2%) = $178.85, Medicare (1.45%) = $41.83.
- State tax estimate (CA ~6.5% effective): ~$171.25 per check.
- Total deductions per paycheck: $268.30 + $178.85 + $41.83 + $171.25 + $250.00 = $910.23.
- Net take-home pay: $2,884.62 - $910.23 = $1,974.39.

What is the difference between gross pay and net pay?
Gross pay is your total earned income before any withholdings, while net pay (take-home pay) is the actual amount deposited into your bank account after all taxes and benefits are deducted.
How do pre-tax deductions save money on taxes?
Pre-tax deductions (such as traditional 401(k) and health insurance premiums) reduce your taxable income before federal and state taxes are calculated, lowering your overall tax liability.
