How to use this calculator
- Enter the requested values for clock-in time, clock-out time, unpaid break (minutes).
- Review each input for the correct unit, pay period, and policy assumption.
- Calculate the result and read the explanation shown with each output.
- Compare the estimate with your time records, agreement, payroll system, or employer policy before relying on it.
Input guide
Clock-in time
Provide the clock-in time used for this specific estimate. Use the same period and unit as the other inputs.
Clock-out time
Provide the clock-out time used for this specific estimate. Use the same period and unit as the other inputs.
Unpaid break (minutes)
Provide the unpaid break (minutes) used for this specific estimate. Use the same period and unit as the other inputs.
Elapsed shift
Provide the elapsed shift used for this specific estimate. Use the same period and unit as the other inputs.
Paid time
Provide the paid time used for this specific estimate. Use the same period and unit as the other inputs.
Payroll decimal
Provide the payroll decimal used for this specific estimate. Use the same period and unit as the other inputs.
How this calculator works
Paid minutes = clock-out − clock-in − unpaid break. Overnight shifts automatically roll into the next day.
Worked example
9:00 AM to 5:30 PM with a 30-minute unpaid break equals 8.00 paid 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
Duration display
Elapsed and paid durations are rounded to the nearest whole minute.
Payroll decimal
Decimal hours are rounded to two decimal places using standard half-up display rounding.
Assumptions and limitations
- Times describe one continuous shift.
- Break time is unpaid.
- Results are planning estimates, not payroll records.
Frequently asked questions
Does it handle overnight shifts?
Yes. A clock-out earlier than clock-in is treated as the following day.
How are decimal hours rounded?
The displayed payroll decimal is rounded to two decimal places.
When should I recalculate with the Time Card 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 Time Card 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.
