Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Sales Tax Calculator
Calculate the sales tax owed on a purchase given the pre-tax price and the applicable tax rate — useful for budgeting US purchases (where sales tax is added at the register and varies state-by-state) and for working out the tax portion of any receipt where it is shown separately. Enter the price before tax and the combined state+local tax rate as a percentage, and the calculator returns the dollar amount of tax. To get the total amount payable, add this tax to the original price. This calculator does not handle the reverse direction (gross-to-net) or true European-style VAT, which is usually quoted inclusive of tax rather than added on top.
Income Tax Calculator
Estimate your US federal income tax liability by entering your annual gross income, filing status, and standard deduction — the calculator subtracts the deduction and applies a simplified single rate per filing status. A back-of-envelope tool; for accurate progressive bracket math use the full bracket calculator.
