how to calculate the over time ?

Hi,

To calculate OT, you have to determine the OT multiplier first. Normally OT is calculated at 1.5 times the normal rate, but it would be 2 times during public holidays.

To calculate the hourly rate for the purpose of OT, you may consider:

case 1:
assuming in a year, No of Public Holidays = 16, No of Non Work Days (i.e. weekend for 5-day week) = 104
Total no of work days = 365 - 16 - 104 = 245
Average work days per month = 245 / 12 = 20.42

Then for OT base rate = Salary / 20.42 / 8

case 2:
Calculate work day on a monthly basis, assuming in a particular month, No of Public Holidays = 1, No Of Non Work Days = 9
Total no of work days for current month = 31 - 1 - 9 = 21

Then for OT base rate = Salary / 21 / 8
