A measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food and medical care. The CPI is calculated by taking price changes for each item in the predetermined basket of goods and averaging them; the goods are weighted according to their importance. Changes in CPI are used to assess price changes associated with the cost of living.
RBI is releasing the CPI index every month. See RBI site for details.

Dear keerthikeyanm,
I shall make a brief on Consumer Price Index, its compilation,
its necessity or how it is related with DA etc. Hence I start with DA.
Considering the living cost and all, Wage Revision is being done once in five years or ten years. But inflation will go up day by day and subsequently the money value will come down. To compensate this we have to wait till the next Wage Revision, which is not practical. That is why the DA is introduced.
The devaluation of money can be assessed through Whole Sale Price Index, All India Cosumer Price Index etc. The difference between these two is that, price variation of all commodities are taken into account for Whole Sale Price Index.
But for AICPI there are some differences/ limitations.
1. There is a particular Consumer viz. Industrial Worker.
2. Some specified goods & services are defined, called "basket of goods".
3. Along with the price variation of commodities, its consumable quantity will also be considered.
4. All over India 78 Centres are selected to take average
In India, the All India Consumer Price Index was 1st taken in the year 1960. Percentage of average price is taken as Consumer Price Index. As 1960 being the base year, CPI will be 100 on that year. To calculate the variations there after, I shall quote one example.
A family needs 20kgs of rice, 5Kgs of sugar & 30Ltrs of milk in a month. In a particular interval the price hiked from Rs. 20 from Rs. 25 per Kg for rice, Rs. 20 to Rs. 30 per Kg for Sugar & Rs. 10 to Rs. 13 per Ltr for milk. Then the price at base stage is 20x20+5x20+30x10 = 800 (Base points 100). After price hike it will be 20x25+5x30+30x13 = 1040. Revised point is 1040 / 800 x100 = 130. Here new cosumer price index is 130 and variation in points is 30.
In 1982 October the AICPI is 493. Means Average prices increased by 4.93 times comparing that of 1960.
Based on All India Consumer Price, Industrial DA being paid; variable in quarters commencing from January, April, July & October. I.e. for January the AICPI will be the average of previous September, October & November. Similarly for April it will be December, January & February, for July it will be March, April & May and for October it will be June, July & August respectively.
When the money devaluation is fully compensated it is called as full DA neutralisation. The formula for full DA neutralisation = (Total points - Base points)/ Base points (in percentage). The AICPI is introduced in India in 1960 and revised in 1982 & 2001. AICPI of 2001 x 4.63, we get AICPI of 1982 and AICPI of 1982 x 4.93, we get AICPI of 1960. For DA calculation AICPI of 1960 is accepted as the base.
Now in India mainly two term's wage settlements are in exist; Wage Settlements of 1.1.1997 & 1.1.2007. The base point in 1.1.1997 is 1708 & in 1.1.2007 is 2884.
I shall quote one example,i.e. calculation of AICPI for July '10. This is equalent to average of previous March, April & May; which recorded as 170, 170 & 172 (Base year 2001). Multiply with 4.63 and round, we get 787,787 & 796 (Base year 1982). Multiply with 4.93 and round, we get 3880,3880 & 3924 (Base year 1960). Find average of these 3 and round, we get 3895.
DA for 1.1.97 scale. Total points - 3895, Base points - 1708, Total - Base = 2187. % is 2187/1708 x 100 = 128.0 ( Correct to one decimal).
DA for 1.1.2007 scale. Total points - 3895, Base points - 2884, Total - Base = 1011. % is 1011/2884 x 100 = 35.1 ( Correct to one decimal).
I shall insert Excel sheet for IDA calculation w.e.f 1.10.2008. You may extent the rows further (as necessary) and just enter the 3 indexes towards the year 2001 in green colour columns. The results will appear in yellow and red is used for static informations.
