About Paycheck Math

Paycheck Math builds free money calculators that show exactly where every number comes from.

We cover take-home pay, income tax, sales tax and VAT, mortgages, loans, retirement savings, end-of-service gratuity, zakat, gold prices and currency conversion for the United States, the United Kingdom, Canada, Australia, Germany and the Gulf. The site has 1703 pages, one for each calculator, country, state, province and common salary.

How we work

Every tax rate, bracket and threshold is stored with the official page it comes from and the date it was checked. Changes are approved by a person before they reach a page. Calculations run in your browser; we never see your salary.

Pages are reviewed by Soufyane S.. Found a wrong number? Tell us and we will check it against the source the same week.
