Understanding Dearness Allowance (DA) Calculation
Considering the living cost and all, wage revision is typically conducted once every five or ten years. However, inflation continues to rise daily, leading to a decrease in the value of money. Waiting until the next wage revision to compensate for this is often impractical, which is why the concept of Dearness Allowance (DA) was introduced.
The devaluation of money can be assessed through indices such as the Wholesale Price Index and the All India Consumer Price Index. The key distinction between these two indices lies in the fact that the Wholesale Price Index considers price variations of all commodities, whereas the All India Consumer Price Index focuses on a specific consumer group, such as industrial workers, and a designated set of goods and services known as the "Basket of goods."
Calculation and Adjustment of Industrial Dearness Allowance (DA)
Based on the All India Consumer Price Index, Industrial Dearness Allowance (DA) is paid and adjusted quarterly starting from January, April, July, and October. For instance, the AICPI for January is calculated as the average of the previous September, October, and November figures. Similarly, the April calculation considers December, January, and February; July considers March, April, and May; and October considers June, July, and August.
When full compensation for money devaluation is achieved, 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 All India Consumer Price Index was introduced in India in 1960 and subsequently revised in 1982 and 2001. By multiplying the AICPI of 2001 by 4.63, we obtain the AICPI of 1982, and by multiplying the AICPI of 1982 by 4.93, we derive the AICPI of 1960. The AICPI of 1960 serves as the base for DA calculation.
Wage Settlement Terms and DA Calculation Example
In India, there are primarily two wage settlement terms in existence: Wage Settlements of 1.1.1997 and 1.1.2007. The base point for 1.1.1997 is 1708, while for 1.1.2007, it is 2884.
For instance, let's consider the calculation of AICPI for July '10. This involves averaging the figures from the previous March, April, and May, which are recorded as 170, 170, and 172 (Base year 2001). Multiplying these figures by 4.63 and rounding, we obtain 787, 787, and 796 (Base year 1982). Further multiplying by 4.93 and rounding, we get 3880, 3880, and 3924 (Base year 1960). Averaging these three results and rounding yields 3895.
For the DA calculation for the 1.1.1997 scale, the total points are 3895, the base points are 1708, and the difference is 2187. The percentage is calculated as 2187/1708 x 100 = 128.0 (correct to one decimal).
Regarding the DA calculation for the 1.1.2007 scale, the total points are 3895, the base points are 2884, and the difference is 1011. The percentage is calculated as 1011/2884 x 100 = 35.1 (correct to one decimal).
I will include an Excel sheet for IDA calculation effective from 1.10.2008. You may extend the rows as needed and input the three indexes towards the year 2001 in green columns. The results will be displayed in yellow, while red is reserved for static information.
