Hours worked
Hours = (clock-out − clock-in) − unpaid break · Pay = hours × rate

Convert times to a 24-hour clock first, subtract, then take off any unpaid break. Overtime in the US is typically 1.5× the regular rate for hours beyond 40 in a week. Minutes convert to decimals for payroll: 15 min = 0.25 h, 30 min = 0.5 h, 45 min = 0.75 h.

Calculating paid hours

Enter when you clocked in and out and how long your unpaid break was. The calculator subtracts the break and shows your worked time in HH:MM and in decimal hours — the format payroll uses to multiply by your rate. Add an hourly rate to see gross pay.

Overnight shifts are supported: if the end time is before the start time, it's counted as the following day.

Frequently Asked Questions

How are worked hours calculated? +

We take the difference between the end and start time, subtract the unpaid break minutes, and express the result in both HH:MM and decimal hours (which payroll systems use).

Does it handle overnight shifts? +

Yes. If the end time is earlier than the start time, it is treated as the next day, so overnight shifts calculate correctly.

What are decimal hours? +

Decimal hours express minutes as a fraction of an hour — for example 8:30 is 8.5 decimal hours. Payroll typically multiplies decimal hours by the pay rate.
