DA with effect from 1st July 2016

As the 7th Pay commission recommendations will be implemented with effect from 1.1.2016, the AICPIN average of 2015 will be the Base Index for calculation of DA for 7th Pay Commission

So formula for Calculation of DA in 7th Pay Commission is
= (12 months Average of AICPIN -261.4) divided by 261.4 multiply by 100
=[(263+264+266+269+270+269+269+267+268+271+275+277)/12]- (261.4)X100/261.4
= 2.91 %
