Hours Inside a Window Calculator

How much of a shift falls inside a window you define, and pay at a rate and a per-hour amount you type.

What it does

the overlap between the shift and the window you set, in hours, and pay from the rate and extra-per-hour you type. The window is your own choice, not a rule.

The page is arithmetic: it reads the numbers you type and returns hours and, where a rate is involved, a gross figure from your own numbers. It is not a payroll system, it decides nothing, and no rate, threshold, break length or rule is stored in the tool. A box you leave empty is treated as zero.

Where the rules live

The state rule text on this site is restated from the US Department of Labor Wage and Hour Division tables on the state pages, and the authority for every rule is the Department of Labor and your state labor office. This page does not interpret any of it.
