How to read decimal hours
Decimal hours express minutes as a fraction of an hour. 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75. So 8 hours 30 minutes becomes 8.50 — the format most payroll and invoicing tools expect.

Turn a clock-in and clock-out into hours worked. Enter your start and end times, subtract any unpaid break, and get the shift length in hours-and-minutes and in payroll-ready decimal hours — overnight shifts included.
Hours for one shift
Figures update as you type. Times are 24-hour; an end time before the start is treated as overnight.

Paid vs unpaid breaks
Only unpaid breaks should be subtracted from worked time. A paid coffee break stays in the total; an unpaid lunch comes out. Enter just the unpaid minutes in the break field.
Overnight shifts
If you clock in at 22:00 and out at 06:00, the calculator assumes the shift crossed midnight and counts 8 hours rather than a negative number. No need to add a date.
Tracking a whole week?
This tool handles a single shift. To add up Monday through Sunday with automatic overtime over 40 hours, use the Weekly Timesheet Calculator.
FAQ
Common questions about this calculator.
How do I calculate hours from clock-in and clock-out?
Subtract the clock-in time from the clock-out time, then subtract any unpaid break. For example, 9:00 to 17:30 is 8.5 hours; take off a 30-minute lunch and you have 8.0 paid hours.
What are decimal hours?
Decimal hours express minutes as a fraction of an hour: 15 minutes is 0.25, 30 is 0.50, 45 is 0.75. Payroll systems use decimals, so 8 hours 30 minutes is entered as 8.50.
Does it handle overnight (graveyard) shifts?
Yes. If the clock-out time is earlier than the clock-in time, the shift is treated as crossing midnight, so 22:00 to 06:00 correctly returns 8 hours.
Should I subtract paid breaks?
No. Only enter unpaid break minutes. Paid breaks stay part of your worked time, so leave them out of the break field.
