Overview
Calculate the actual extra time in a shift after breaks. Useful for employees and employers, and for comparing summer or overnight schedules.
Formula
Find the shift length, deduct the break, then compare with standard hours. The excess is overtime and the deficit is unfinished time.
How it works
Enter start and end
Overnight shifts are supported.
Deduct the break
Enter the total break minutes.
Set standard hours
Usually 8, then read the overtime.
Worked examples
An 8-to-6 shift
10 hours before the break, 9 after a one-hour break, so one hour over 8.
A night shift
From 22:00 to 07:00 with a 45-minute break gives 8 hours and 15 minutes.
