About PayMath
Free pay calculators. Instant answers.
PayMath is a small set of pay calculators for common questions: what an hourly job pays per year, what a salary is worth per hour, how overtime adds up, and how long it takes to earn a dollar amount.
Every tool runs in your browser. There are no accounts, no backend math servers, and no need to sign in. Numbers stay on your device.
Results are estimates for education and planning. They are not tax, legal, or employment advice. Overtime rules and tax withholding vary by job, state, and filing status.
