What Are Decimal Hours?

Decimal hours express time as a decimal number of hours instead of hours and minutes, which makes it easy to multiply by an hourly rate. To convert, divide the minutes by 60: 30 minutes = 0.5 hours, 45 minutes = 0.75 hours, and 8 hours 20 minutes = 8.33 hours.

Why Payroll Uses It

Pay = decimal hours × hourly rate. 8.33 hours at 18 an hour equals 149.94.

Common Mistake

8:30 on a clock is 8.5 decimal hours, not 8.30.
