USA Calculators
The United States has a progressive federal income tax, payroll (FICA) taxes, and a patchwork of state rules — so estimating your real take-home pay or tax bill takes a few moving parts. These free tools use 2026 US figures to help you plan income tax, capital gains, mortgages, retirement, self-employment taxes and more, all running privately in your browser.
