How hours worked are calculated
hours = finish time − start time − unpaid break
Each day is worked out in minutes, then added up for the week. If a shift finishes earlier on the clock than it started, it crossed midnight, so 24 hours are added to the finish time before subtracting.
Converting to decimal hours
Payroll systems usually want hours as decimals. Divide the minutes by 60:

Overtime
With overtime switched on, hours over 40 in the week are paid at 1.5 times your rate — the US federal standard for most hourly workers. Daily overtime, double time and rules in other countries vary, so treat the pay figure as an estimate before tax.
Subtract the start time from the end time, then subtract unpaid breaks. 9:00 am to 5:30 pm is 8 hours 30 minutes; minus a 30-minute lunch, that's 8 hours.
How do I convert minutes to decimal hours?+
Divide the minutes by 60. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. Payroll usually needs decimal hours, so the calculator shows both.
What about shifts that go past midnight?+
Enter the times as they are. If the end time is earlier than the start time, the calculator assumes the shift finished the next day: 10:00 pm to 6:00 am is 8 hours.
When does overtime start?+
In the US, the federal rule for most hourly workers is time-and-a-half for hours over 40 in a week. Some states (such as California) also count daily overtime, and rules differ in other countries, so check your contract or local law.
