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.

Important Difference
Paid Breaks vs Unpaid Breaks
This calculator is designed to subtract unpaid break time from your shift. Paid breaks are usually counted as time worked, while unpaid breaks are usually deducted from total work hours.
Unpaid Breaks
Unpaid breaks are not normally counted as working time. A common example is an unpaid lunch or meal break. If your lunch break is unpaid, enter those minutes into the calculator.
Paid Breaks
Paid breaks are usually included in your working time. If a rest break is paid, you usually should not subtract it from your work hours in this calculator.
