Free Time Card Calculator
Calculate total work hours from punch-in and punch-out times for payroll.
Quick answer
Hours for a day = punch-out time − punch-in time − unpaid breaks. Add up the days for the week, then pay = regular hours × hourly rate + overtime hours × overtime rate. Example: 9:00 to 18:30 with a 30-minute lunch break is 9 hours.

Frequently asked questions
How do I convert minutes to decimal hours for payroll?
Divide the minutes by 60. 8 hours 45 minutes = 8 + 45 ÷ 60 = 8.75 hours.
Can punch times be collected automatically?
Yes. Staff Khata records punches from Realtime biometric machines, a rotating QR code or selfie + GPS, and works out hours and late marks for each day.
