        ஜூலை 2012 முதல்   DA  உயர்வு 7% ஆக இருக்கும் என எதிர்பார்க்கப்படுகிறது .DA வானது All India Consumer Price Index ஐ அடிப்படையாக கொண்டு நிர்ணயிக்கப்படுகிறது.

DA rate from 01.07.2012 to be fixed at 72 % which is a increase of 7 % from previous rate of 65 % 
DA(dearness allowance rates are fixed on the basic of All India Consumer Price Index for industrial workers.Base year has been taken as 2001. This new DA rate system is adopted by Central and State Govts and public sector Under takings from 01.01.2006 with new pay scale as declared by the Pay commission .

Price Index for Last 12 month

How to calculate Dearness Allowance from the year 2006:It is very simple ,suppose if you want to calculate Dearness Allowance with effect from Jan-12, get the average of monthly All India Consumer Price Index for industrial workers with the base year 2001=100 for the preceding 12 months and apply the same in the following formula

Dearness Allowance = (Avg of AICPI for the past 12 months - 115.76)*100/115.76
(ignore fractions)
Here 115.76 means average of price index from Jan 2005 to Dec 2005.
So to calculate July 2012 DA rate (to be announced) we need Price index average from July 2011 to June 2012.As per Labour Bureau, Department Statistics, Government of India website index for July 2011 to  May 2011 has already been declared ,But for May,2012 and June,2012 yet to be declared.
AICPI data for July 2011 to June ,2012( May & June 2012 estimated basis)

Jul-11	Aug-11	Sep-11	Oct-11	Nov-11	Dec-11	Jan-12	Feb-12	Mar-12	Apr-12	May-12	Jun-12	total	AVG
193	194	197	198	199	197	198	199	201	205	206	209	2396	199.67

We have assumed AICPI for June 2012 to 209. Further even if June2012 Index declared  in between 203-216 . Calculation of Dearness rate Increase from July 2012 remains the same i.e 7 % and new dearness allowance from 01.07.2012 will be declared at 72 %.(100% sure) 
On the Basis of The assumption the calculation is given as under.
Dearness allowance (01.07.2012)=(199.67-115.76)*100/115.76=72.48 (ignore fraction)=72 %
so  DA rate from 01.07.2012 to be fixed at 72 % which is a increase of 7 % from previous rate of 65 % .
