EPF Pension Calculation - EPF Pension = Pensionable Salary * Number of Years of Service/70?

As per details of "PPO Enquiry Sheet" received by my colleague on attaining the age of 58 (Superannuation) on 15th March 2018, pension details are as below:

- Pension amount: Rs. 2967/-
- Past Service Up to 15-11-1995: 5 Years, 7 Months, and 15 Days
- Date of Joining: 01-04-1990
- Date of Exit: 15-03-2018
- Reason for Exit: Superannuation
- Eligible Service: 28 Years
- Wage on 15-11-1995: Rs. 1200/-
- Wage on Date of Exit: Rs. 15000/-
- Actual Service After 15-11-1995: 22 Years, 3 Months, and 27 Days
- Pensionable Service: 22 Years, 1 Month, and 27 Days
- NCP Days: 61 Days
- Pensionable Salary: Rs. 12144/-
- Weightage Service: 2 Years

As per our understanding, PF Pension will be calculated based on the following formula:
EPF Pension = Pensionable Salary * Number of Years of Service / 70

If we calculate the pension based on the above formula, he should get Rs. 4163/- (12144 * 24 / 70). There is a difference of Rs. 1196/- in the pension amount as per our workings and the PPO sheet.

Request members to enlighten us on the PF Pension calculation.

The calculation appears alright. Please verify from the local RPFC how the pension amount was fixed.

Dear Kalaparam,
You worked prior to 15.12.1995. Also you worked after 15.12.1995. To you the pension calculation formula is different.
Following formula is applicable to you:
Past Service benefit (plus) Pensionable service benefit (less) Proportionate reduction subject to minimum pension specified for each group.
What you need to do is as under:
1. For past service benefit you have to calculate pension amount for the period before the 16/11/1995.
2. For pensionable service benefit you have to calculate the pension for the period after 16/11/1995 as per the formula mentioned by you.
3. You need to check the proportionate reduction subject to minimum period depending on when the pension started or date of commencement of pension.
Calculation of pension amount for the period before the 16/11/1995 is very complex subject which one need to study. I had given presentations on this calculation but right now I have forgotten it. Till last year I had the presentation material which I discarded it in 5S carried out by me.

I started working under PF Act from 16.04.2013. When should I be applicable for pension and how much?

How is the pensionable salary calculated?
