Unpaid break
Provide the unpaid break used for this specific estimate. Use the same period and unit as the other inputs.
Hours worked

How this calculator works
Worked minutes = clock-out − clock-in − unpaid break.
Worked example
8:30 AM to 5:00 PM with 30 unpaid minutes equals 8.00 hours.
How to interpret the result
Use the displayed result as a planning figure, not as an official payroll determination. A materially unexpected result usually means the entered period, rate, threshold, break, accrual rule, or conversion basis should be checked.
Rounding policy
Worked duration
Calculated to the nearest whole minute.
Decimal hours
Displayed to two decimal places.
Assumptions and limitations
- One continuous shift.
- The entered break is unpaid.
Frequently asked questions
Can the shift cross midnight?
Yes. An earlier clock-out is treated as the next day.
Are breaks deducted?
Yes, enter the total unpaid break minutes.
When should I recalculate with the Hours Worked Calculator?
Recalculate whenever the hours, rates, schedule, pay period, policy assumptions, or planned usage changes. Saving the exact inputs makes comparisons more reliable.
How accurate is the Hours Worked Calculator?
The arithmetic follows the formula shown on the page. Real payroll or policy outcomes can still differ because of contracts, jurisdictional rules, employer systems, taxes, deductions, caps, and rounding practices.
