How it is worked out
- For each line: end − start − break (a shift that ends before it starts runs past midnight).
- Add the shifts: 2,190 minutes = 36.5 hours. Gross pay ignores overtime rules and tax.

| One shift per line: start end break: 09:00 17:30 30 09:00 17:00 30 08:30 16:30 30 09:00 17:00 30 09:00 15:00 0; Hourly rate: 20 | 5 shifts add up to 36 h 30 min (36.5 hours), or $730.00 at $20.00 an hour. |
| One shift per line: start end break: 22:00 06:00 30 22:00 06:00 30; Hourly rate: 18 | 2 shifts add up to 15 h 00 min (15 hours), or $270.00 at $18.00 an hour. |

How to use it
Write each shift as start end break, for example 09:00 17:30 30 for 9 am to 5:30 pm with a 30-minute break. The calculator subtracts the break from each shift, adds the shifts and shows the total in hours and minutes and in decimal hours. Enter an hourly rate to see the gross pay.
Shifts that end before they start run past midnight. Overtime rules, rounding policies and tax differ by employer and place, so the pay shown is simple gross pay.
