About EarningsMath

EarningsMath is a free calculator site focused on work hours, pay and PTO arithmetic. The calculators are designed for quick checks around time cards, timesheets, hourly wages, salary conversions, overtime estimates, pay periods, shift differentials and paid time off.

Who it is for

The site can be useful for workers checking their own numbers, managers reviewing schedules, small teams estimating gross labor costs, and anyone comparing simple work and pay scenarios in the United States.

What the calculators do

Each tool uses visible formulas or straightforward arithmetic based on values entered by the user. Results are estimates and should be checked against the relevant employer policy, payroll record, agreement or applicable rule.

What EarningsMath does not do

EarningsMath does not provide legal, tax, payroll, employment or financial advice. It does not determine whether overtime, PTO payout, a specific wage, or any other employment outcome is legally required.
