Work Hours Calculator - Calculate Hours Worked

This work hours calculator helps employees, managers, and small business owners calculate hours worked from real shift times. Add start time, end time, and unpaid break minutes for each day, then review total work hours, regular hours, overtime hours, and optional gross pay.

Use it after the week has happened, when you need to total actual hours worked. If you are planning a future schedule instead, use the work schedule maker. If you need a broader tool for any type of elapsed time, use the hours calculator.

How to Calculate Work Hours

Work Hours Formula

Work hours = End time - Start time - Unpaid breaks
Weekly work hours = Sum of daily work hours
Overtime hours = Weekly work hours - Overtime threshold

If weekly work hours are below the overtime threshold, overtime hours are zero.

Work Hours Example

This week totals exactly 40 work hours. If the employee works another three-hour Saturday shift and the overtime threshold is 40 hours, the extra three hours are overtime in many weekly overtime setups.

Best Uses

• Employee self-checks before submitting a timesheet.
• Manager payroll review when a time clock export needs a quick audit.
• Contractor billing when start and end times need to become billable hours.
• Shift coverage review when comparing actual hours to scheduled hours.
