How it works
An hours calculator totals time worked from clock-in and clock-out times, subtracting breaks. It converts each shift to hours and minutes (or decimal hours for payroll) and sums them across the period.
Hours worked
Worked = (clock out − clock in) − breaks Decimal hours = minutes ÷ 60
- clock in/out
- shift start and end times
- breaks
- unpaid break time
Worked example
- In 8:00 AM, out 4:30 PM
- 30-minute unpaid lunch
- Gross = 8.5 hours
- Minus 0.5 break
8 hours worked.
Good to know
- Convert minutes to decimal (15 min = 0.25 h) for pay calculations.
- Hours over 40 in a week may qualify for overtime at 1.5×.
- Round consistently — many employers round to the nearest quarter hour.

Frequently Asked Questions
How do I calculate hours worked between two times?
Subtract the start time from the end time, then subtract unpaid breaks. A 9:00 AM to 5:30 PM shift with a 30-minute unpaid lunch is 8.5 − 0.5 = 8 hours. For overnight shifts, the calculator handles crossing midnight automatically.
How do I convert minutes to decimal hours?
Divide the minutes by 60: 7 hours 45 minutes = 7 + 45/60 = 7.75 hours. Payroll systems use decimal hours, so 15 minutes = 0.25, 30 minutes = 0.50, and 45 minutes = 0.75.
Do breaks count as paid time?
Under US federal rules, short breaks of roughly 5-20 minutes are normally paid work time, while bona fide meal periods of 30+ minutes where you're fully relieved of duties can be unpaid. Subtract only the unpaid breaks when totaling hours.
How do I total a weekly timesheet?
Compute each day's hours (end − start − unpaid breaks), convert to decimal, and sum the days. For non-exempt US employees, hours beyond 40 in the workweek are overtime paid at time-and-a-half.
What's the difference between hh:mm format and decimal hours?
7:30 in hours-and-minutes equals 7.5 decimal hours — the minutes are out of 60, not 100. Mixing the two is a common payroll error: writing 7.30 for 7 hours 30 minutes underpays by 12 minutes.
