How the shift calculator works

Start and end time:
Enter when the shift starts and ends.

Break time:
Enter unpaid break minutes to subtract from the shift length.

Overnight shifts:
If the end time is earlier than the start time, the calculator can treat the end time as the next day.

Weekly estimate:
The calculator multiplies one shift length by the number of shifts per week and estimates regular and overtime pay.
