Work Hours Estimate

Calculate hours worked between a start time and end time after subtracting break minutes.

How this work hours calculator works

The calculator finds the time between start and end, then subtracts unpaid break minutes. If the end time is earlier than the start time, it treats the shift as crossing midnight.

Use it for a single shift. Use the time card calculator if you need Monday through Sunday totals.

Example work hours calculation

If you start at 9:00 AM, end at 5:30 PM, and take a 30-minute unpaid break, the estimate is 8.00 worked hours.

If you start at 10:00 PM and end at 6:00 AM with a 30-minute break, the estimate is 7.50 worked hours.

When to verify the result

Your employer rounds clock punches.
Meal breaks are paid or partially paid.
You worked an overnight shift.
Time records include travel, on-call, or training time.
Payroll uses a different timekeeping system.
