Time Clock Calculator

How to use the time clock calculator

Use the time clock calculator to convert daily punches into paid hours. Enter the start and end of each shift, subtract unpaid breaks and optionally enter an hourly rate for an estimated gross amount.

From time-clock punches to hours worked

A time-clock calculation starts with the clock-in and clock-out punches for each shift. WorkTimeCheck converts them to elapsed minutes, subtracts the entered unpaid break and converts the remaining duration into daily and weekly work-hour totals.

For example, clocking in at 7:45 AM and out at 4:15 PM creates an 8-hour-30-minute elapsed period. Subtract a 30-minute unpaid break and the calculated paid duration is 8 hours.

Calculating weekly time-clock totals

The daily results are summed across the displayed workweek. This avoids manually adding mixed hour-and-minute values and also provides a decimal-hour representation where useful. If an hourly rate is entered, the calculator uses the resulting hours for its optional estimated-pay display.

Check the entries against the original punches before using the total elsewhere. A calculator cannot identify a forgotten punch, an incorrectly entered time or an employer-specific rounding rule.

Time clock calculator versus a timekeeping system

WorkTimeCheck is intended for checking and estimating hours from times you provide. It does not record attendance, authenticate employees, preserve an audit trail, approve timesheets or send data to payroll.

For shifts crossing midnight, an end time earlier than the start is treated as the following day. Unpaid break minutes are deducted after the elapsed shift duration is determined.
