Overtime Hours Calculator

Overtime Hours Calculator is a free suite of browser-based payroll and time calculators built for hourly employees, small-business owners, and HR or payroll admins who need fast, accurate answers without spreadsheets or paid software. The core time and a half calculator instantly converts a regular hourly wage and hours worked into blended pay, correctly applying federal FLSA overtime rules for any hours worked beyond 40 in a week. A time to decimal converter turns clock times such as 7:45 into decimal hours so they drop straight into payroll systems without manual conversion errors. A time card totals tool adds up multiple daily clock-in and clock-out entries into an accurate weekly total automatically, removing the tedious arithmetic that payroll admins usually redo by hand or in a spreadsheet every single pay period.

Every calculation on the site runs entirely client-side in the browser. There is no sign-up, no account creation, no ads, and no data of any kind is ever sent to a server or stored anywhere outside the user's own device, which matters for anyone handling sensitive payroll or wage information. Results update live as the user types, and each calculator shows its underlying math step by step so people can verify exactly how the number was produced rather than trust an opaque black box. The goal of the project is simply to save hourly workers, small business owners, and lean payroll teams the handful of minutes they would otherwise spend on manual overtime arithmetic, time conversion, or time card totalling, packaged as a fast, free, no-friction browser tool that anyone can bookmark and reuse every pay period without ever creating an account.
