Considering the living cost and all, wage revision is being done once in five years or ten years. However, inflation will go up day by day, and subsequently, the money value will decrease. To compensate for this, we have to wait until the next wage revision, which is not practical. That is why the Dearness Allowance (DA) is introduced.
The devaluation of money can be assessed through the Wholesale Price Index, All India Consumer Price Index, etc. The difference between these two is that the price variation of all commodities is taken into account for the Wholesale Price Index.
However, for the All India Consumer Price Index, there are some differences/limitations:
1. There is a particular consumer, namely the Industrial Worker.
2. Some specified goods and services are defined, called the "basket of goods."
3. Along with the price variation of commodities, the consumable quantity will also be considered.
4. All over India, 78 centers are selected to take an average.
Based on the All India Consumer Price Index, Industrial DA is being paid, variable in quarters commencing from January, April, July, and October. For example, for January, the AICPI will be the average of the previous September, October, and November. Similarly, for April, it will be December, January, and February; for July, it will be March, April, and May; and for October, it will be June, July, and August, respectively.
When the money devaluation is fully compensated, it is called full DA neutralization. The formula for full DA neutralization = (Total points - Base points)/Base points (in percentage). The AICPI was introduced in India in 1960 and revised in 1982 and 2001. By multiplying the AICPI of 2001 by 4.63, we get the AICPI of 1982, and multiplying the AICPI of 1982 by 4.93, we get the AICPI of 1960. For DA calculation, the AICPI of 1960 is accepted as the base.
In India, mainly two terms of wage settlements exist; the Wage Settlements of 1.1.1997 and 1.1.2007. The base point in 1.1.1997 is 1708, and in 1.1.2007 is 2884.
An example calculation of AICPI for July '10 is as follows: This is equivalent to the average of the previous March, April, and May; which is recorded as 170, 170, and 172 (Base year 2001). Multiply by 4.63 and round, we get 787, 787, and 796 (Base year 1982). Multiply by 4.93 and round, we get 3880, 3880, and 3924 (Base year 1960). Find the average of these 3 and round, we get 3895.
DA for 1.1.1997 scale: Total points - 3895, Base points - 1708, Total - Base = 2187. The percentage 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. The percentage is 1011/2884 x 100 = 35.1 (Correct to one decimal).
I shall insert an Excel sheet for IDA calculation effective 1.10.2008. You may extend the rows further as necessary and just enter the 3 indexes towards the year 2001 in green color columns. The results will appear in yellow, and red is used for static information.
