About
Take-home pay calculators for all 50 US states and Washington DC, built on the 2026 federal brackets, the FICA wage base and each state's own rules, including the states with no wage income tax and the ones with extra payroll levies such as California SDI and New York PFL.
Every calculator page shows the result, the formula behind it, a worked example you can redo by hand, the published source it was checked against with the date of that check, and a plain section on where the answer stops being right.
Next to the paycheck pages sit mortgage, amortization, HELOC, 401(k), Roth IRA, RMD, CD, APY and inflation calculators, plus calculators for health, math, construction, science and everyday sums: 243 in all.
Free, no account, no ad network. 847 golden-value tests pin the results, so a changed tax table or formula fails before it ships.
