A work hours calculator estimates the total time worked during a shift using the start and end times and, the break duration (if applicable). It helps employers and small business owners review shift lengths and understand how much time is scheduled or recorded as working time.
For small businesses, consistent work-hour calculations can simplify timesheet reviews, support staffing decisions, and assist with payroll preparation. However, the calculation alone does not verify employee attendance or determine all payable hours, which may depend on overtime rules, workplace policies, and applicable labor laws.
Calculate the time between the shift start and end, then subtract any unpaid break included in the calculation. For shifts that cross midnight, the calculation must account for the change of day.
General Formula: Total work hours = Shift end time − Shift start time − Unpaid break duration
Daily Formula: Daily work hours = Ending time − Starting time − Unpaid break duration
Weekly Formula: Weekly work hours = Sum of daily work hours for the week
Use the calculator’s daily rows to enter work times for each day of the week.
Starting Time: Enter the time the employee’s shift begins.
Ending Time: Enter the time the employee’s shift ends.
Break Deduction: Enter the amount of break time to subtract from that day’s shift.
Total In Hours: Shows the daily working time in hours and minutes after the break deduction.
Weekly Total: Show the total working-time for the week in hours and minutes.
Total Decimals: Show the total decimal-hours.
Suppose an employee works from 9:00 AM to 5:30 PM and takes a 30-minute unpaid break.
| Work detail | Time |
|---|---|
| Shift start | 9:00 AM |
| Shift end | 5:30 PM |
| Elapsed shift duration | 8 hours 30 minutes |
| Unpaid break | 30 minutes |
| Estimated work time | 8 hours |
The employee’s estimated working time is 8 hours after subtracting the unpaid break. Compare the estimate with actual time records and apply workplace policies and applicable laws before using the figure for payroll.
Yes. Enter each day's start time, end time, and break duration, and the calculator will total them to determine weekly work hours, subtracting unpaid breaks where applicable.
Hours and minutes express time as 8 hours and 30 minutes, while decimal hours express the same duration as 8.5 hours. Divide the minutes by 60 and add the result to the whole hours. For example, 7 hours and 30 minutes equals 7.5 hours. Decimal hours can be useful in spreadsheets and payroll software.
Yes. Enter the correct start times, end times, and break durations to estimate working time for part-time, full-time, or flexible schedules.
Not always. Paid hours may depend on break treatment, overtime rules, rounding policies, leave, and other employment conditions.
No. It calculates an estimate from the times entered and does not independently record or verify when employees arrive or leave.
