Should Overtime Be Calculated From Gross Or Total Salary?

can someone help me the calculation of overtime with example? plz immediate reply needed..

Hi Mani
OT Salary to be caluculated
Gross salary/No of days/8*OT hrs*2=OT Amount-ESI 1.75%=Earned amount
Eg :- 5600/26(Days)/8(per day)*1(OT)*2(Double)=53-1(ESI)=52

dear all
OT has to be calculated as double of
BASIC + DA ( monthly/ 26 days/ hours)
and not on gross.

The exact calculation of overtime is as under
No. of working hours in a week is very important for calculating overtime:
For example in a factory the weekly working hours is 48 hrs hence the calculation of vertime will be
BASIC+ DA / 198
198 = 48 *52/12 This factor 198 is derived as follows : In a week 48 hrs in 52 weeks its 8*52 and then diveided by 12.
