While calculating my pension amount under the Employees' Pension Scheme 1995, instead of using the last 60 months' average salary, they have applied a formula to calculate the pension amount, with part of it at Rs. 6500 and the remaining part at Rs. 15000. Since my superannuation date was in December 2018 and a major portion of my contribution was under the Rs. 6500 regime, I am receiving a reduced pension. Can I write to the pension authorities to revisit my pension calculations? Can anyone provide advice on this matter?
