How to add up a week of shifts
For each day you worked, take the end time minus the start time, then subtract any unpaid break. Add the days together. The total is shown two ways: hours and minutes (38:45), which is how people talk about time, and decimal hours (38.75), which is what most timesheets and payroll systems want.
| Day | Start | End | Unpaid break | Worked |
|---|---|---|---|---|
| Mon | 09:00 | 17:30 | 30 min | 8:00 |
| Tue | 08:15 | 16:45 | 45 min | 7:45 |
| Wed | 22:00 | 06:00 | 0 min | 8:00 (overnight) |
| Thu | 09:00 | 15:00 | 0 min | 6:00 |
| Fri | 09:00 | 18:00 | 60 min | 8:00 |
| Total | 37:45 = 37.75 h |
Minutes to decimal hours
| Minutes | Decimal |
|---|---|
| 15 | 0.25 |
| 20 | 0.33 |
| 30 | 0.50 |
| 40 | 0.67 |
| 45 | 0.75 |
Overtime
Under the federal Fair Labor Standards Act, non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. Some states, such as California, also count daily overtime. The calculator shows the total and how much of it is over 40, but it does not compute overtime pay, because the rules depend on your state and contract.

How we calculate
Shift = end − start − unpaid break. An end time at or before the start is the next day (overnight). Week = sum of worked days. Decimal hours = minutes ÷ 60.
- Overtime rules differ by state and contract; the total is shown, overtime pay is not computed.
