Taxes
Tax Withholding Calculator
Calculate the tax withheld from a single paycheck given gross pay and a withholding rate. Use it to estimate what a flat withholding rate produces — for example, a state's flat income-tax rate or the bonus-flat-rate (22% supplemental wage withholding) used by US employers on certain payments.

Taxes
Income Tax Calculator
Calculate income tax owed by applying a flat tax rate to total income — a simplified shortcut for estimating tax burden in flat-rate jurisdictions or for back-of-envelope marginal-rate math. Use it for quick gut-checks; for real US federal tax which uses progressive brackets, use a dedicated tax-bracket calculator instead.
