Dear Akhila & Riya,
I shall provide some information on the All India Consumer Price Index and Industrial DA as follows.
Considering the cost of living and other factors, Wage Revision is typically done every five or ten years. However, with inflation rising daily and the value of money subsequently decreasing, waiting until the next Wage Revision is not practical. This is why Dearness Allowance (DA) is introduced.
The devaluation of money can be assessed through the Wholesale Price Index, All India Consumer Price Index, etc. The key difference between these indices is that the Wholesale Price Index considers the price variation of all commodities.
On the other hand, the All India Consumer Price Index has certain differences and limitations:
1. It focuses on a specific consumer group, namely Industrial Workers.
2. It defines a set of specified goods and services known as the "basket of goods."
3. It considers not only the price variation of commodities but also their consumable quantity.
4. A total of 78 centers are selected nationwide to calculate the average.
Based on the All India Consumer Price Index, Industrial DA is paid variably in quarters starting from January, April, July, and October. For example, the AICPI for January is the average of the previous September, October, and November figures. Similarly, for April, it is the average of December, January, and February, for July it is March, April, and May, and for October it is June, July, and August respectively.
When the devaluation of money is fully compensated, it is referred to as full DA neutralization. The formula for full DA neutralization is calculated as (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 by multiplying the AICPI of 1982 by 4.93, we get the AICPI of 1960. The AICPI of 1960 is accepted as the base for DA calculation.
In India, there are primarily two wage settlements in existence: the Wage Settlements of 1.1.1997 and 1.1.2007. The base points are 1708 for 1.1.1997 and 2884 for 1.1.2007.
I will provide an example calculation for AICPI for July '10: The average of the previous March, April, and May figures is taken as 170, 170, and 172 (base year 2001). After applying the relevant multipliers and rounding, we arrive at the AICPI figures for the base years 1982 and 1960, followed by the final average calculation.
For the 1.1.97 scale, the DA calculation is based on the total points minus the base points, resulting in a percentage. Similarly, for the 1.1.2007 scale, the calculation is done based on the respective points.
I will insert an Excel sheet for IDA calculation effective from 1.10.2008. Feel free to extend the rows as necessary and enter the three indexes towards the year 2001 in the green columns. The results will be displayed in yellow, while red is used for static information.
