Minutes as decimals
Payroll multiplies decimal hours by your rate, so 7 hours 30 minutes is entered as 7.5, not 7.30. Quarter hours are 0.25, 0.5 and 0.75; 10 minutes is 0.17 and 20 minutes is 0.33.
Questions people ask
How many hours is 9 to 5?
8 hours on the clock. With a 30-minute unpaid lunch it is 7.5 paid hours; with an hour’s lunch it is 7.
How do I calculate hours for a night shift?
Enter the times as they are. 10:00 pm to 6:00 am is counted as 8 hours because the end time is taken to be on the following day.
