Formula to calculate IDA rate for 3rd PRC or 2017 pay scale? Example:
- Average AICPIN (2001=100) for the last 3 quarters:
- Feb 2023 = 382.18
- Jan 2023 = 382.46
- Dec 2022 = 381.02
- Average of the quarter = 381.89
- Link point = 277.33 (as on 01.01.2017)
- Increase over Link point = 104.56 = [381.89 – 277.33]
- DA rate effective from 01.04.2023 = 37.7 = [(104.56 / 277.33) x 100]

Disclaimer: Kindly refer dpe.gov.in for any inconsistencies in rules, understandings and clarification.
gov is very garib hai g that is why not giving settled/announced da
What would be the reason to fix lower DA
Govt may club this not-included-da in the next increment..
why fixed 23.2% insteado f 24.6% from 01.07.2021 for 3rd PRC employees
Govt. is giving us IDA rate of 1st April, not of 1st July. Like they gave 28% (DA of 1st Jan) to Central Govt. Employees instead of 31% (DA of 1st July).
Correct, but fixing to one quarter below DA
Well-structured, comprehensive data analysis
thank you..
Because no one is there to question the Government. Further, Govt is unable to provide the logical answer to the question. Probably, this is to avoid increase of HRA for CPSU employees.
Ya, u may be right, but HRA will certainly increase from 1st Oct’21, as DA is crossing 25% at that time..
