What This Calculator Does
The Work Hours Calculator computes the exact hours worked between a start and end time after subtracting breaks. Freelancers tracking time and employees checking pay stubs use it for accurate totals.
How It Works
Start and end times convert to total minutes since midnight, the break is subtracted, and the remainder is divided by 60 for decimal hours. The tool also reports the figure in minutes.
Example
Working 9:00 AM to 5:30 PM with a 30-minute lunch yields 8.0 hours: (1050 - 540 - 30) = 480 minutes, divided by 60.
Formula
Hours = (End − Start − Break) minutes / 60Reading the Results
Hours Worked
The total paid time in decimal hours between start and end, after subtracting unpaid breaks.
Minutes Worked
The same total expressed in minutes, useful for payroll systems that track exact minutes.
Frequently Asked Questions
How do I calculate hours worked by hand?
Convert both times to minutes since midnight, subtract the break, then divide by 60. For example, 9 to 5:30 with a 30-minute lunch is 8 hours.
Does it handle overnight shifts?
Yes. If the end time is earlier than the start time, the calculator treats the shift as ending the next day.
Should breaks be included?
Only unpaid breaks should be subtracted. Paid 15-minute breaks stay within working hours.
