Payroll Calculator

FICA includes Social Security tax at 6.2% of gross pay (up to the annual wage cap) and Medicare tax at 1.45%. Together they reduce your paycheck by 7.65%. An additional 0.9% Medicare surtax applies to earnings above $200,000 annually.

Pre-tax deductions like 401(k) contributions and health insurance premiums reduce your taxable income before income tax is calculated, lowering your tax bill. Post-tax deductions like Roth 401(k) or union dues are subtracted after taxes are applied.

The calculator supports 5 frequencies: weekly (52 paychecks/year), biweekly (26), semi-monthly (24), monthly (12), and annual (1). Changing the frequency recalculates FICA and all deductions proportionally for each pay period.
