Time card calculator with lunch, breaks and overtime

Enter a clock-in and clock-out time for each day worked. The calculator subtracts the unpaid break, shows each day’s paid hours, totals the week in hours and minutes and decimal hours, and estimates overtime and gross pay.

How paid hours are calculated

Paid time = clock-out − clock-in − unpaid break

If a clock-out time is earlier than the clock-in time, the shift is treated as crossing midnight. Saturday and Sunday are optional.

Overtime

The default threshold is 40 hours with a 1.5× multiplier, but both fields can be changed. This is a general estimate; actual overtime rules can vary by worker and jurisdiction.

See how lunch deductions affect a weekly time card

For a five-day schedule of 8:00 AM to 5:00 PM, each day has 9 elapsed hours. If lunch is an unpaid 30 minutes every day, the daily total is 8.50 paid hours and the five-day total is 42.50 paid hours. With a 60-minute unpaid lunch, the same shifts total 40.00 paid hours instead.

Verify your inputs: include all applicable breaks, distinguish unpaid from paid breaks, and review any overnight shift entries. Overtime pay rules and rounding practices vary; a computed weekly hours total alone does not determine legal wages owed.

Frequently asked questions
