Time Card Calculator
Weekly work hours, overtime, and pay from clock-in times.
Quick answer
How do you calculate hours worked?
Subtract clock-in from clock-out, then subtract unpaid breaks. 9:00 AM to 5:30 PM is 8.5 hours; minus a 30-minute lunch is 8 hours. Five days like that is 40 hours — at $20/hour, $800 gross pay.
Daily hours = (clock out − clock in) − break. Weekly pay = regular hours × rate + overtime hours × rate × 1.5.

- Each day: (clock out − clock in) − break minutes. If clock out is earlier, the shift crosses midnight.
- Add every day: 40h 00m = 40 decimal hours (minutes ÷ 60).
- Pay = 40 × $20.00 = $800.00 before taxes.
Enter clock-in, clock-out, and unpaid breaks for each day to total your weekly hours, overtime, and gross pay. Overnight shifts are handled.
