All US paychecks are subject to FICA taxes: Social Security (6.2%) and Medicare (1.45%), totaling 7.65%, plus federal income tax withholding and state/local income taxes.

How is bi-weekly pay calculated from an annual salary?

How Take-Home Pay is Calculated

Net pay equals gross pay minus pre-tax deductions (401k, health insurance), mandatory FICA payroll taxes (6.2% Social Security + 1.45% Medicare = 7.65%), and federal and state income tax withholdings.

Paycheck Formulas:

1. FICA Withholding = Gross Pay × 7.65%

2. Taxable Wage = Gross Pay - Pre-Tax Deductions

3. Income Tax Withholding = Taxable Wage × Income Tax Rate

4. Net Pay = Gross Pay - FICA - Pre-Tax Deductions - Income Tax
