Who we are
A free, independent set of work-hours and overtime calculators. Every rule passes three steps before it reaches a result.
1 Read the law first
Each rule comes from the statute or the agency that enforces it, never from another calculator.
2 Test against it
898 automated tests run on every build, last on November 1, 2026. One is the Department of Labor's own example below.
3 Show the math
Pay results list each line of the sum, the rule used and the date it was last checked.
Reading the stub
The Department of Labor's own case in 29 CFR 778.110: 46 hours at $12.00.
- 6.00 hours are over 40 in the workweek, so they are overtime (29 U.S.C. 207).
- $18.00 is the overtime rate: $12.00 × 1.5.
- $588.00 is $480.00 + $108.00, the same total as the calculator at the top of the page.
Where the rules come from
Each rule is read from the law or the agency that enforces it.

Decimal hours, hours, time duration and 24-hour time work anywhere.

If a result and your pay stub disagree, ask your employer or your state labor department.
