The formula
weekly: overtime = total hours − threshold, if above zero daily: overtime = each day’s hours − threshold, if above zero, added up
On a weekly threshold, overtime is shown on the days after the running total passes it.
What to watch out for
Change the threshold to match how your overtime is defined, for example 40 hours per week or 8 hours per day. Breaks you enter are not counted as worked time.
Frequently Asked Questions
How do I work out overtime hours?
Total the hours, then take off the threshold. Five days of 09:00 to 18:30 with 30-minute breaks is 45 hours, so 5 hours are over a threshold of 40.
Can a weekly and a daily threshold give different answers?
Yes. Days of 10, 10, 10 and 6 hours total 36, so there is no overtime past 40 per week, but 6 hours past 8 per day.
