How US take-home pay is calculated
Your federal take-home pay is your gross salary minus federal income tax and FICA (Social Security and Medicare). This calculator uses the 2026 federal brackets, standard deduction and wage bases.
Federal income tax
Tax is charged on your taxable income — gross pay minus the standard deduction ($16,100 Single, $32,200 Married Filing Jointly for 2026). The seven progressive brackets run from 10% to 37%, so only the income inside each bracket is taxed at that rate.
FICA: Social Security & Medicare
FICA is charged on your gross wages, not your taxable income. Social Security is 6.2% on the first $184,500 of wages; Medicare is 1.45% with no cap. Together they make up 7.65% for most workers.
State income tax, pre-tax 401(k)/HSA contributions and the 0.9% Additional Medicare surtax on high earners are not modeled.
