How to Calculate IDA after 7th CPC?
Here is a step-by-step breakdown of the IDA calculation:
1. DA is paid for any increase in AICPIN (All India Consumer Price Index Numbers) above the quarterly index average of 1708, which is the reference point for the revised pay scales.
2. The percentage increase in the quarterly average of AICPIN for the periods ending in February, May, August, and November, compared to the base index of 1708, is calculated to one decimal point.
3. The rate of compensation for PSE employees above the basic pay at the index average of 1708 is expressed in whole numbers, with any fractions carried forward.
4. Quarterly averages are computed as follows:
– January IDA: September, October & November
– April IDA: December, January & February
– July IDA: March, April & May
– October IDA: June, July & August
IDA Calculation Method with Example
To determine the precise IDA percentage for CPSE employees, we need to consider three months of AICPIN data. However, at present, we only have data for two months: July and July 2024. The AICPIN for August has not yet been released by the Labour Bureau.
For this calculation, we will assume that the AICPIN for August will also be 139.7. Now, let’s proceed with the calculation method:
June 2024: 136.4 (Declared)
July 2024: 139.7 (Declared)
August 2024: 139.7 (Expected)
