Hours Worked Calculator
Add up shift hours and subtract unpaid breaks
Payroll rules last updated: July 2026. Sources & methodology.
Shift inputs
net time after breaks
This calculator totals a single shift. If the end time is earlier than the start time, it is treated as an overnight shift crossing midnight.
How this is calculated
Enter a start time, end time, and unpaid break minutes. The calculator finds elapsed time between the two clock times, subtracts breaks, and returns decimal hours plus hours-and-minutes format.
If end time is earlier than start time on the clock, the shift is treated as crossing midnight — useful for overnight work. Paid meal breaks should not be subtracted; only enter unpaid break minutes.
To total a full week and estimate gross pay with overtime, use the time card calculator.
Hours worked = (end time - start time, with midnight rollover) - unpaid break minutes
