Time Card Calculator
Enter your clock-in and clock-out times to calculate your total hours worked for the day. The calculator subtracts your lunch break, shows the result in both standard and decimal format, and flags any overtime beyond 8 hours.
This time card calculator converts your 12-hour AM/PM times to 24-hour format, computes the total gross hours, subtracts the lunch break, and presents the net working hours. It also handles overnight shifts (clocking in PM and out AM the next day).
The decimal-hours output is the format most payroll systems use. For example, 8 hours 15 minutes equals 8.25 decimal hours. Multiply by your hourly rate to get gross pay. Overtime (any net hours beyond 8) is flagged separately for easy tracking.
For weekly totals, run the calculator for each day and sum the decimal hours. Under the Fair Labor Standards Act, overtime is paid at 1.5x the regular rate for hours exceeding 40 per week, though some states (like California) also require daily overtime after 8 hours.
