Pension Calculation of EPS 95 - after 20 years service

Sir, the details of my service are as follows. Please send the calculation of Pension as per EPS 95:

Date of Birth - 28.6.1957
Date of joining 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)
Deduction of Contribution from 1.9.2014 to 30.6.2015 (Completion 58 years) - Rs. 1250/- on salary Rs. 15000/- (Statutory Ceiling)
My Pension entitlement from 1.7.2015
Past Service - 11 years 6 months (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 to 20 years.

Dear friend,

Your past service benefit = 95 x 4.485 = 426 - (1)

Pensionable amount up to 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

By virtue of completion of 20 years of EPS membership, 2 years of bonus membership will be added to pensionable service.
