Paycheck Calculator
See your real take-home pay per paycheck after 401(k), HSA, health insurance, federal, state, local taxes, and W-4 adjustments — 2026 IRS rates.
Advanced: W-4 Adjustments
Withholds at the single-filer rate even if married. Increases federal withholding.
Dependent credit: $2,000 per qualifying child + $500 per other dependent. Step 4a-4c covers non-wage income, extra deductions, and additional per-paycheck withholding.
How the Paycheck Calculator Works
Your paycheck starts with gross pay per pay period (weekly, bi-weekly, semi-monthly, or monthly), then a sequence of deductions and taxes determine your net take-home. Bi-weekly (26 paychecks/year) and semi-monthly (24 paychecks/year) are not the same — they produce different per-paycheck amounts even at the same annual salary.
Pre-tax deductions are not all equal. Traditional 401(k) contributions reduce your federal and state income tax base, but do not reduce FICA (Social Security + Medicare). HSA contributions and Section 125 health insurance premiums reduce all three — federal, state, and FICA. Roth 401(k) contributions reduce none of them — they're post-tax. This calculator applies each rule correctly, so a $200/paycheck HSA contribution will save you more than a $200/paycheck 401(k) contribution at the same gross.
Federal withholding follows the IRS Publication 15-T Percentage Method, simplified to use the 2026 brackets and standard deduction directly. W-4 Step 2 (multiple jobs / spouse works) shifts withholding to the single-filer rate, increasing per-paycheck federal tax. Step 3 (dependent credits) reduces it. Steps 4a-4c handle non-wage income, extra deductions, and additional per-paycheck withholding.
FICA is 6.2% Social Security up to the wage base ($184,500 in 2026) and 1.45% Medicare on all income. An additional 0.9% Medicare tax kicks in above $200k (single / HOH), $250k (married), or $125k (married filing separately). State tax is calculated from your state's brackets; local tax is a flat rate you enter (e.g. NYC ~3.876%, Philadelphia ~3.79%).
