The employer must keep an overtime register, and pay slips should show overtime hours and the overtime rate separately.
How is overtime pay calculated?
The tool divides monthly basic plus DA by the working days in the month to get daily wages, then by normal daily hours to get the hourly rate. It doubles the hourly rate and multiplies it by the overtime hours worked. For example, Rs 30,000 over 26 days of 8 hours gives about Rs 144.23 an hour, or Rs 288.46 an hour for overtime.
