Paycheck Calculator — Gross pay minus federal income tax, Social Security, Medicare, and state income tax equals your take-home pay. The federal calculation uses the 2024 percentage-method brackets from IRS Publication 15-T, annualised and divided by your pay periods, with the standard deduction subtracted. FICA (Social Security + Medicare) is calculated exactly as payroll systems do it: 6.2% on gross up to the $168,600 wage base for Social Security, 1.45% on all gross for Medicare, plus 0.9% on amounts above $200,000 (single) or $250,000 (married) for the additional Medicare tax.
All tax math runs locally. No salary data leaves your device.
Estimates are simplified for education only — not payroll, legal, or tax advice. Real withholdings vary by jurisdiction, benefits, and personal situation. Check your actual payslip.

State tax is approximated with a flat marginal rate. Real state brackets vary (some are progressive like the federal system, some are flat, some states have no income tax at all), but a flat rate gives a reasonable estimate for planning purposes. For a more accurate number for your state, look up your state's withholding tables or use the IRS Tax Withholding Estimator at irs.gov/W4app.
