The hours calculator adds or subtracts time values to find total hours worked, elapsed time, or accumulated durations. Enter start and end times, or a list of time intervals, and get the total instantly. It handles multiple shifts, overnight work, and decimal-to-hours-minutes conversion for payroll and scheduling.
How to Calculate Hours Worked
For a single shift, subtract start time from end time. For overnight shifts, add 24 hours to the end time before subtracting. For multiple entries, calculate each interval and add them. Convert minutes to decimal fractions of an hour for payroll systems that use decimal hours.
Hours Worked = End Time - Start Time Overnight: Hours = (End Time + 24:00) - Start Time Minutes to Decimal: Minutes / 60 Example: 7 hours 45 minutes = 7 + (45/60) = 7.75 hours
15 min = 0.25 hr, 30 min = 0.50 hr, 45 min = 0.75 hr.

Frequently Asked Questions
How do I add hours and minutes together?⌄
Add the minutes first. If total minutes exceed 60, convert the excess to hours. Then add the hours. Example: 3h 45m + 2h 30m. Minutes: 45+30=75. 75-60=15 minutes and 1 extra hour. Hours: 3+2+1=6. Total = 6 hours 15 minutes.
How do I calculate pay for partial hours?⌄
Convert hours and minutes to decimal hours by dividing minutes by 60. Then multiply decimal hours by hourly rate. 7 hours 45 minutes = 7.75 hours. At $20/hour: 7.75 × $20 = $155. Most payroll systems use this decimal method.
How do I handle overnight shifts in hours calculation?⌄
If the shift ends the next day, add 24 hours to the end time before subtracting. Example: Start 10:30 PM, End 6:30 AM. Convert end time: 6:30 AM + 24h = 30:30. Subtract: 30:30 - 22:30 = 8:00 hours. The same logic applies when calculating with clock time.
What is the difference between work hours and billable hours?⌄
Work hours count all time at work, including breaks, administrative tasks, and non-billable activities. Billable hours count only time spent on client work that can be invoiced. Professionals like lawyers, consultants, and freelancers track both. Most employers pay for all scheduled work hours. Freelancers typically only invoice billable hours.
