How are work hours calculated?
For a single shift, subtract the start time from the end time and then subtract unpaid breaks:
For a weekly total, add the paid hours from every day. The calculator then separates time above your chosen threshold:
- Breaks entered in Daily mode are treated as unpaid.
- Weekly fields should contain paid hours after breaks.
- An end time earlier than the start time is treated as an overnight shift.
- The result is not a payroll decision or legal determination.
Common payroll time conversions
Divide minutes by 60 to convert clock minutes into decimal hours.
Work hours calculator FAQs
How do I calculate hours worked between two times?
Subtract the start time from the end time, then subtract any unpaid break. For example, 9:00 AM to 5:30 PM is 8.5 elapsed hours. After a 30-minute unpaid break, the result is 8 paid hours.
Can this calculator subtract lunch and other breaks?
Yes. In Daily mode, enter the total unpaid break duration in minutes. The calculator deducts it from the elapsed shift. Do not subtract paid breaks.
How do I calculate weekly work hours?
Select Weekly and enter the paid hours worked on each day. The calculator adds the seven daily values and separates hours above the overtime threshold you enter.
Does the calculator support overnight shifts?
Yes. If the end time is earlier than the start time, the calculator treats the shift as ending the following day. For example, 10:00 PM to 6:00 AM is eight elapsed hours before breaks.
How are minutes converted into decimal hours?
Divide the minutes by 60. For example, 15 minutes is 0.25 hours, 30 minutes is 0.50 hours and 45 minutes is 0.75 hours. Seven hours and 30 minutes should be entered as 7.50, not 7.30.
Does this tool calculate overtime pay?
No. It separates hours above a threshold, but it does not multiply hours by an overtime rate or determine whether a worker legally qualifies for overtime. Rules vary by jurisdiction and employment arrangement.
Is my work-hour data saved?
No work-hour entries are sent to Backlsh by this calculator. The calculation runs in your browser. A PDF is generated only when you choose Export PDF.
What is the easiest way to track employee work hours?
A calculator is useful for checking an individual shift or week. For an ongoing team process, automatic time tracking can create consistent timesheets and reduce manual reconstruction at the end of the week.
