Time Card Overtime Calculator
Standard Formula
Daily Duration = Clock Out - Clock In - Break Duration
Converts daily punch clock timestamps into net compensable work hours and daily overtime.
How Time Card Overtime Calculator Works?
The Time Card Overtime Calculator works by subtracting clock-in time and unpaid break minutes from clock-out time, then splitting the net hours into regular hours (up to 8) and daily overtime.
1Enter the hourly rate
Type the base wage, $25.00 by default.
2Enter clock-in and clock-out
Use 24-hour decimal time: 8.0 = 8:00 AM, 18.5 = 6:30 PM.
3Enter the unpaid break
Add unpaid meal minutes, 30 by default.
4Read shift pay
10.5 elapsed hours − 0.5 break = 10.00 net hours: 8 regular hours plus 2 overtime hours returns $275.00.
Time Card Overtime Calculator Formula
The Time Card Overtime Calculator formula is Net Hours = Clock Out − Clock In − (Break Minutes ÷ 60).
Net hours
Net = Out − In − Break ÷ 60
Daily overtime
Daily OT = Max(0, Net − 8)
Shift pay
Pay = Min(Net, 8) × Rate + Daily OT × Rate × 1.5
- In, Out
- Punch times in decimal 24-hour format.
- Break
- Unpaid meal break in minutes.
- Net
- Compensable hours for the shift.
Worked example: 7:15 AM to 4:45 PM
In = 7.25, Out = 16.75, Break = 45 minutes (0.75 hours).
Net = 16.75 − 7.25 − 0.75 = 8.75 hours (8h 45m), with 0.75 hours of daily overtime.
Time Card Overtime Calculator Conversion Table
The Time Card Overtime Calculator conversion table converts 8 punch pairs with a 30-minute unpaid break into net hours and pay at $25.00 per hour.

What is Time Card Overtime Calculator?
A Time Card Overtime Calculator is a tool that turns punch-in and punch-out times into net paid hours and overtime for one shift.
The FLSA requires employers to keep records of hours worked each workday and workweek under 29 CFR Part 516. Paper time cards, punch clocks and mobile apps all produce the same 3 inputs: in, out and break.
The tool flags overtime after 8 hours in a day, which matches daily-overtime states. Workers in weekly-only states add daily totals across the week to find overtime.
