Calculating Work Hours for Timesheets
Work-hour calculations usually start with the elapsed time between clock-in and clock-out, then subtract unpaid breaks. For example, 08:00 to 16:30 is 8.5 elapsed hours; subtracting a 30-minute unpaid break leaves 8 paid hours. When several shifts are combined, calculate each shift consistently before totaling the week. Overnight work needs special handling because the end time falls on the next day. Employers may also use rounding rules, paid breaks, overtime thresholds or different definitions of compensable time, so a mathematical total may not exactly match payroll. Decimal hours are convenient for payroll systems: 15 minutes equals 0.25 hour, 30 minutes equals 0.5 and 45 minutes equals 0.75. For official pay calculations, apply the workplace policy and local employment rules that govern the actual timesheet.
