Expected IDA from October 2026 for PSU – Calculator & AICPI Data
Based on the latest AICPI-IW data, view the projected Industrial Dearness Allowance for CPSE employees from October 1, 2026.
Quick Answer: What is the Expected IDA from October 2026?
The expected IDA from October 2026 for PSU employees is currently projected to be approximately 56.7% for the 2017 Pay Scale and 243.9% for the 2007 Pay Scale.
This projection is based on the All India Consumer Price Index (AICPI-IW) data up to June 2026. The final official rate will be confirmed by the Department of Public Enterprises (DPE) after the July and August 2026 indices are officially released.
For employees of Central Public Sector Enterprises (CPSEs) and Public Sector Undertakings (PSUs), the Industrial Dearness Allowance (IDA) is a crucial salary component that is revised quarterly. Following the July 2026 hike, the next revision will take effect from October 1, 2026. Because this rate depends heavily on inflation trends measured by the AICPI-IW index for June, July, and August, many employees closely track the expected IDA calculation before the official DPE order is released.

How Is IDA for PSU Employees Calculated?
The Department of Public Enterprises (DPE) uses a fixed formula to calculate the Industrial Dearness Allowance. It relies on the 12-month average of the All India Consumer Price Index for Industrial Workers (AICPI-IW) (Base Year 2016=100 for the 2017 pay scale).
[(12 Monthly Average of AICPI - Base Index) / Base Index] × 100
The quarterly calculations are tied to specific months of the AICPI index:
- Expected IDA from Jan 2026: Based on September, October, and November indices.
- Expected IDA from April 2026: Based on December, January, and February indices.
- Expected IDA from July 2026: Based on March, April, and May indices.
- Expected IDA from October 2026: Based on June, July, and August indices.
When Will the Official IDA from October 2026 Be Announced?
The official Office Memorandum (OM) from the DPE detailing the exact IDA rates is typically published in the month the revision takes effect. Therefore, the confirmed rate for October 2026 is expected to be announced in early to mid-October 2026. However, the final AICPI data required for the calculation (the August index) is usually released at the end of September, allowing employees to know the exact percentage shortly before the official order.
