Dear Mr. Sanjeev ji,
As per PF Act the pension calculation goes as below:
Pensionable Salary * Pensionable Service / 70 (What ever the gross earnings of the employee pension slab will be same)
Now the Pensionable Salary is 6500...
You have worked for around 18 yrs 6 months...
70 is stands for the maximum Age limit of a person..
So, as per my knowledge it is goes like this:
6500 * 19 / 70 = Rs. 1,764/- approximately..
Apart from that you will get PF Accumulations amount for the service (Both employee and Employer), Gratuity for your service in the Organization etc..
You will be eligible for Pension after attaining 58 years of Age.., you need to apply for Scheme Certificate by putting 'YES' mark in Form 10-C. After attaining you may apply for pension.
Note: PF authorities are willing to increase the the slab for pensionable salary from Rs. 6500/- to 15,000/- but it is not yet been finalized.
