Sir, The details of my Service as under please send the calculation of Pension as per EPS 95.:
Date of Birth - 28.6.1957
Date of join in Service - 21.3.1984
Salary on 16.11.95 - Rs. 2000
Contribution of Deduction before 1.9.2014 Rs.541/- on salary Rs. 6500/-(Statutory Ceiling)

My Pension entitlement from 1.7.2015
Past Service - 11 yr 6 m (approx) from 21.3.1984 to 16.11.95.
The Service from 16.11.95 to 30.6.2015 - 19 years and 7 months rounded 20 years.

Dear friend,
Your past service benefit = 95 x 4.485 = 426 - (1)
Pensionable amount upto 31.8.2014 = 6500 x 18.7863/70 = 1744 - (2)
Pensionable amount from 1.9.2014 to 27.6.2015 = 7775 x 0.8276/70 = 92 - (3)
Pensionable amount without weightage = (2) + (3) = 1836
Pensionable amount with 2 yr weightage = 1836 x 21.6139/19.6139 = 2023 - (4)
Total pension (1) + (4) - 426 + 2023 = 2449.
Abbas.P.S
