With the introduction of new series, a linking factor will be required to bridge old series of CPI and new consumer price index for calculating DA for Central Government Employees and pensioners.

As per Govt’s press release, the maiden index on new base for September, 2020 stands at the level of 118 and linking factor for the conversion of new series index to previous series on base 2001=100 is 2.88.

This linking factor will have to be used to convert CPI (IW) announced by Government from September 2020. For example, Consumer Price Index with base 2016=100 for the month of September 2020 is 118.1 can be converted to CPI with base 2001=100 as 118.1 X 2..88 = 340.13 (rounded as 340 to the nearest whole number). Like wise, consumer price index for the subsequent months i.e from October 2020 are also to be calculated.

This calculation is given below.

Consumer Price Index from July 2020 to Dec 2020 :

Month Actual AICPI-IW

Feb 2020 328
Mar 2020 326

Aug 2020 338
Sep 2020 340
Oct 2020 344
Nov 2020 345

Calculation of DA using the above data is as follows:

DA with effect from 1st January 2021 = [ (330+328+326+329+330+332+336+338+340+344+345+342)/12]-(261.4)X100/261.4
