Hours calculator FAQ
How do I convert minutes to decimal hours?
Divide the minutes by 60. 30 minutes is 0.50 hours, 45 minutes is 0.75 and 20 minutes is 0.33. So 7 hours 45 minutes is 7.75 hours. The chart on this page lists every minute from 1 to 60.
How do I calculate hours worked between two times?
Subtract the start time from the end time, then take off unpaid breaks. From 9:00 AM to 5:30 PM with a 30-minute lunch is 8 hours 30 minutes minus 30 minutes, or 8.00 hours.
What if the shift goes past midnight?
Type the end time as it is, for example 10:00 PM to 6:00 AM. When the end is earlier than the start, the calculator adds a day and shows 8:00 hours, marked overnight.
Is 7.30 hours the same as 7 hours 30 minutes?
No. 7.30 decimal hours is 7 hours 18 minutes. 7 hours 30 minutes is 7.50 decimal hours. Mixing the two is a common payroll mistake, so check which one your time card or pay system uses.
Which formats can I type?
7:30, 7.5, 7h 30m, 7 hrs 30 mins, 450m and 45 min all work. A plain number such as 8 or 7.5 is read as hours.
How do I work out pay from hours and minutes?
Convert the time to decimal hours first, then multiply by the hourly rate. 37 hours 45 minutes at 20.00 an hour is 37.75 × 20 = 755.00. Type a rate under Hours between times to see it worked out.
