Frequently Asked Questions
Quick answers to common questions
Why do payroll systems use decimal hours?
Payroll systems use decimal hours because it makes it much easier to multiply time by an hourly rate (e.g. 7.5 hours × $20/hr is easier to compute than 7 hours and 30 minutes × $20/hr).
Is 7.30 the same as 7 hours and 30 minutes?
No. 7.30 in decimal hours means 7 and 3/10ths of an hour (which is 7 hours and 18 minutes). 7 hours and 30 minutes is 7.50 decimal hours.
