About Tallyclock

Tallyclock offers free calculators for time cards, hours and overtime. They run in your browser and need no account.

Why it exists

Time card math is simple until overtime rules come in. Some states count hours by the day, and others only by the week. These calculators apply the general rules and show the steps, so you can check them against your pay stub.

What we can and cannot tell you

The results are estimates. They do not replace payroll software, your employer or the state labor agency. The methodology page lists what is modeled, what is not, and where each rule comes from.
