How Punch Card Hours Are Calculated

Punch card hours are calculated by:

Formula

Total Hours = (Punch Out Time - Punch In Time) - Break Time

Overtime Hours = Total Hours - Regular Hours (if applicable)

For example, if you punch in at 8:00 AM and punch out at 5:00 PM with a 30-minute lunch break, your total hours would be:

Example Calculation

(5:00 PM - 8:00 AM) = 9 hours

9 hours - 0.5 hours (break) = 8.5 hours
