DA Hike Update: A DA hike of up to 4% is possible! Understand the salary increase through calculations..
There is welcome news for the lakhs of central government employees and pensioners grappling with the impact of inflation. The picture regarding the Dearness Allowance (DA) and Dearness Relief (DR) applicable from July 2026 has become largely clear. The Labour Bureau under the Ministry of Labour and Employment has released the final figures for the All India Consumer Price Index for Industrial Workers (AICPI-IW) for June 2026. According to the latest data for June 2026, the index has surged by 1.1 points to reach the 151.9 mark, with the average AICPI-IW for this period standing at 148.65.
With the release of these figures, it is certain that government employees will see a significant hike in their salaries during the upcoming festive season. Employees often wonder how the government actually determines the Dearness Allowance. Some believe that the DA is calculated simply by finding the difference between the January and July index figures, but that is not the case at all. Let us understand in detail the mathematics behind this salary hike—what the AICPI index is and by how much your salary is set to increase in July 2026. To understand this, let us first look at the AICPI-IW figures for the past 12 months. AICPI-IW Index: Trend over the last 12 months

What is the AICPI-IW, and how does it determine salary?
Dearness Allowance is directly linked to rising inflation in the market. The metric used by the government to measure this is known as the AICPI-IW, or the 'All India Consumer Price Index for Industrial Workers'.
To put it simply, the Labour Bureau collects data on the prices of essential daily-use items (such as rations, clothing, fuel, medicines, rent, etc.) from various industrial centers across the country. If the market prices of these items rise, the index also moves upward. Based on this index, the government determines how much employees' salaries should be increased in proportion to inflation so that their standard of living is not adversely affected. These figures are released on the last day of every month, reflecting the inflation status of the preceding month. AICPI-IW (Index) Record (2024–2026)

January 2025 | January 2024 to December 2024 | 141.15
July 2025 | July 2024 to June 2025 | 143.54
January 2026 | January 2025 to December 2025 | 145.24
July 2026 | July 2025 to June 2026 | 148.65
**Why is a 12-month average used to calculate Dearness Allowance (DA)?**
A common misconception regarding DA calculation is that the DA percentage is determined simply by calculating the difference between the January AICPI index and the July index. This notion is entirely incorrect. Dearness Allowance is never derived from the difference in the index over just one or two months.
The government reviews the Dearness Allowance every six months. There is a prescribed formula under the 7th Pay Commission for this purpose, which always involves calculating the average of the index over the preceding 12 months.
**For January DA:** AICPI figures from January to December of the previous year (total 12 months) are aggregated, and the average is calculated by dividing the sum by 12.
**For July DA:** The average of the figures from July of the previous year to June of the current year (total 12 months) is taken. This is done to ensure that a sudden, sharp rise or fall in inflation during any single month does not cause a drastic fluctuation in the DA calculation. Calculating a 12-month average yields a balanced and accurate figure for the entire year, reflecting the true state of inflation.
How is the final DA percentage calculated?
Once the 12-month average index is determined, it is applied to a specific formula prescribed by the 7th Pay Commission. This formula works as follows:
Formula: [{(12-month average AICPI-IW × 2.88) − 261.41} ÷ 261.41] × 100
First, the 12-month average is multiplied by 2.88 (the linking factor). Next, 261.42 (the base year figure) is subtracted from the resulting number. Finally, the remaining figure is divided by 261.42 and multiplied by 100. The percentage derived from this mathematical process represents the total Dearness Allowance. A key rule in this process is that the government typically disregards the decimal values, applying only the whole number (integer) as the allowance.
