Time Card Calculator
Enter your punches the way the clock recorded them — in, out for lunch, back in, out for the day. We convert everything to decimal hours, apply the rounding rule your employer uses, and split regular from overtime week by week.

Time Card Red Flags
Identical punches every day. Real punches vary. A card that reads 8:00–4:30 for six months usually means someone typed the schedule instead of the clock.
Auto-deducted meals. If the system removes 30 minutes whether or not you took lunch, the working lunches are unpaid work.
Edits without notice. Supervisor edits are legal, but you should be told and the original punch should remain in the audit trail.
Averaged weeks. 46 hours plus 34 hours is 6 overtime hours, not zero. Overtime is per workweek.
