How to Calculate Total Work Hours (Step-by-Step)
Accurate work hours calculation is essential for fair employee compensation, accurate project invoicing, and labor compliance. Follow these standard steps to compute work hours manually or use our free calculator above:
Convert to 24-Hour Time
Convert standard 12-hour clock times to military / 24-hour format (e.g. 5:30 PM becomes 17:30) to eliminate AM/PM ambiguity.
Subtract Start from End Time
Subtract your start time from end time to determine gross duration. For overnight shifts, add 24 hours to the end time before subtracting.
Deduct Unpaid Breaks & Convert
Deduct unpaid lunch and break intervals, then divide remaining minutes by 60 to obtain decimal hours (e.g. 45 mins ÷ 60 = 0.75 hrs).

Frequently Asked Questions
How does the Work Hours Calculator calculate daily and decimal hours?
It computes the exact duration between your Start Time (Clock In) and End Time (Clock Out), subtracts your unpaid lunch or break minutes, and converts the resulting time into both standard Hours:Minutes format (e.g. 7h 45m) and Decimal Hours (e.g. 7.75 hrs) for payroll entry.
Does this calculator support overnight or night shifts?
Yes. If your shift starts in the evening (e.g. 9:00 PM) and finishes the next morning (e.g. 5:30 AM), the calculator automatically detects the overnight rollover and computes the exact elapsed work duration accurately.
Why convert work hours to decimal format?
Payroll software and hourly paychecks require decimal hours to multiply by your hourly wage. For example, 30 minutes equals 0.50 hours, and 15 minutes equals 0.25 hours.
