Minutes to decimal formula
Decimal Hours = Hours + (Minutes ÷ 60) Example: 7 hours 45 minutes 7 + (45 ÷ 60) = 7 + 0.75 = 7.75 decimal hours Most payroll and timesheet systems want time entered as a decimal, not as hours:minutes — this is why "7:45" on a time clock needs to become "7.75" on a pay stub before it can be multiplied by an hourly rate.

Frequently asked questions
How do I convert minutes to decimal hours for payroll?
Divide the minutes by 60 and add that to the whole hours. 7 hours and 45 minutes becomes 7 + (45÷60) = 7.75 decimal hours, which is the figure most payroll systems expect rather than "7:45."
What is 15 minutes in decimal hours?
15 minutes is 0.25 decimal hours — a quarter of an hour. 30 minutes is 0.5, and 45 minutes is 0.75.
Why doesn't my payroll system match this calculator exactly?
Some payroll systems round clock times to the nearest quarter-hour before converting, rather than using the exact minute count — so 7 hours 52 minutes might get entered as 7.75 (rounded to the nearest 15-minute mark) instead of the exact 7.87 this calculator shows. That rounding is a company timekeeping policy, not a universal rule, so check with your employer or payroll provider if the two don't match.
How do I convert decimal hours back to minutes?
Take the part after the decimal point and multiply it by 60. 7.75 hours has 0.75 remaining after the whole 7 hours; 0.75 × 60 = 45 minutes, so 7.75 decimal hours is 7 hours 45 minutes.
