Hours and Minutes Calculator
Payroll uses decimal hours: divide the minutes by 60, so 20 minutes is 0.33 hours.
How the hours and minutes calculation works
Enter each time as hours and minutes
Type 3 and 45 for 3 h 45 min. Minutes over 59 are fine: 90 minutes counts as 1 h 30 min.
Choose add or subtract for each line
Subtract an unpaid break or time already paid. Blank lines are skipped.
Add the minutes, then carry every 60 into an hour
45 + 30 + 50 − 45 = 80 minutes, which is 1 h 20 min. Add that to 3 + 2 + 1 = 6 hours: 7 h 20 min.
Divide by 60 for decimal hours
7 h 20 min is 440 minutes, and 440 ÷ 60 = 7.33 hours. That is the number to multiply by an hourly rate.
Worked example. A worker logs three jobs: 3 h 45 min, 2 h 30 min and 1 h 50 min, and 45 minutes of that was an unpaid break. The total is 440 minutes, or 7 h 20 min, which is 7.33 decimal hours.
Hours and Minutes FAQ
How do I add hours and minutes?
Add the hours and the minutes separately, then turn every 60 minutes into an hour. 3 h 45 min + 2 h 30 min is 5 h 75 min, which is 6 h 15 min.
How do I subtract hours and minutes?
Convert both times to minutes, subtract, then convert back. 7 h 15 min − 2 h 40 min is 435 − 160 = 275 minutes, which is 4 h 35 min.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60 and add them to the hours. 7 h 20 min is 7 + 20 ÷ 60 = 7.33 hours. 15 minutes is 0.25, 30 is 0.5 and 45 is 0.75.
Why does my total look wrong when I add times on a normal calculator?
A normal calculator counts in hundreds, but an hour has 60 minutes. 1.45 + 1.30 gives 2.75, but 1 h 45 min + 1 h 30 min is 3 h 15 min. Convert to minutes or decimal hours first.
How do I calculate pay from hours and minutes?
Convert the time to decimal hours, then multiply by the hourly rate. 7 h 20 min is 7.33 hours; at $20 an hour that is $146.67.
Is this the same as the hours worked calculator?
No. This page adds up durations you already know. The hours worked calculator finds the time between a start and an end time, and the time card calculator totals a week of shifts.
