Minutes to decimal hours
Payroll systems record time in decimal hours. Divide minutes by 60, or use this table.

How the time card adds up
- Daily hours. End time minus start time, minus unpaid break minutes. Overnight shifts are handled automatically.
- Weekly overtime. Hours over 40 in the week are paid at 1.5 times your rate, the federal rule for non-exempt employees.
- California daily overtime. If you choose it, hours over 8 in a day are paid at 1.5 times and hours over 12 at double time, and regular hours over 40 in the week also become overtime. California's seventh-day rule is not included.
Common questions
How do I calculate hours worked?
For each day, subtract your start time from your end time and then subtract any unpaid break. For example, 9:00 AM to 5:30 PM with a 30-minute unpaid lunch is 8 hours. Add the days together for your weekly total.
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.5 and 45 minutes is 0.75, so 7 hours 45 minutes is 7.75 hours. Payroll uses decimal hours to work out your pay.
When do I get overtime?
Under federal law, non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. A few states, most notably California, also require overtime for long days: 1.5 times after 8 hours and double time after 12 hours in a day.
Do breaks count as hours worked?
Under federal rules, short breaks of about 5 to 20 minutes count as paid working time. Meal breaks of 30 minutes or more usually do not, as long as you are fully relieved of duty. Some states have their own break rules.
How do I calculate time and a half?
Multiply your hourly rate by 1.5 to get your overtime rate, then multiply by your overtime hours. At $20 an hour, overtime pays $30 an hour, so 5 overtime hours add $150 before tax.
