Calculate Hours Worked After Breaks

A break time calculator helps you work out how many hours you actually worked after subtracting unpaid break time. This is useful for employees, hourly workers, freelancers, managers, and anyone who needs to calculate shift hours more accurately.

For example, if you work from 9:00 AM to 5:00 PM and take a 30-minute unpaid lunch break, your total shift length is 8 hours, but your actual paid work time may be 7.5 hours.

How It Works

How to Calculate Work Hours After Breaks

To calculate hours worked after breaks, first find the total time between your start and end time. Then subtract any unpaid break minutes.

Break Time Formula

Total hours worked = shift end time − shift start time − unpaid break time

If your shift crosses midnight, the calculator automatically treats the end time as the following day.

1. Enter Your Start Time

Add the time your shift began. This could be the time you clocked in, started work, or began a freelance work session.

2. Enter Your End Time

Add the time your shift ended. If the end time is earlier than the start time, the calculator treats it as an overnight shift.

3. Subtract Unpaid Breaks

Enter your total unpaid break time in minutes. The calculator subtracts this from your total shift length.
