How Many Hours Is a 10-Hour Shift With Breaks?
A 10-hour shift is a 10-hour span between start and finish. If unpaid breaks fall inside that span, subtract them to calculate net working time. The result depends on whether the stated shift length includes breaks.

If the scheduled span is 10 hours
A shift from 7 AM to 5 PM spans 10 hours. A 30-minute unpaid lunch leaves 9 hours 30 minutes of net work time; a 60-minute unpaid lunch leaves 9 hours.
This example assumes the 10 hours describes the time between clock-in and clock-out.
If the employer means 10 paid hours
Some schedules describe 10 hours of paid work, with unpaid lunch added on top. In that case, a 30-minute unpaid lunch may mean being at work for 10 hours 30 minutes. Confirm how the schedule is defined.
This distinction prevents the common mistake of treating a paid-hours target and a total shift span as the same thing.
Calculate multiple breaks
If you have a 30-minute unpaid lunch and a 15-minute unpaid break, total unpaid time is 45 minutes. Subtract 45 minutes from the full shift span. Count paid breaks according to the applicable policy.
Record each break accurately instead of using a generic assumption.
Check the net total
Use the work hours calculator to subtract unpaid break time. For long or overnight schedules, also confirm the start and end dates and any rules specific to your workplace.

Example: a 10-hour shift with a break
A shift from 7:00 AM to 5:00 PM spans 10 hours. If the worker takes a 30-minute unpaid break, paid work time is 9 hours and 30 minutes, or 9.50 decimal hours. Confirm whether any additional breaks are unpaid before recording the total.
