Hours and minutes to decimal hours
Payroll systems use decimal hours: divide the minutes by 60. 7 hours 30 minutes is 7.5 hours; 7 hours 45 minutes is 7.75; 20 minutes is 0.33 of an hour.
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 | 60 | 1.00 |
Overtime rules
Under the US Fair Labor Standards Act, non-exempt employees must be paid at least one and a half times their regular rate for hours over 40 in a workweek. A few states go further: California also requires overtime for more than 8 hours in a day, and double time over 12. Exempt salaried employees are not covered. Since 2025, up to $12,500 a year of the overtime premium can be deducted from federal income tax; see the income tax calculator.
Military time
The 24-hour clock runs from 00:00 (midnight) to 23:59. Afternoon hours add 12: 1:00 PM is 13:00, 5:30 PM is 17:30. Time fields above accept either format depending on your device settings.
