So, what happens is that suppose you are going to buy something. After all, you paid 500 rupees. Suppose you bought rice, milk, and peanut butter. This is in the month of January 2025. But after the next month, you buy the same things—rice, milk, and peanut butter—but this time you have to pay 550 rupees. It’s the same items, but the prices increased. So, 50 rupees have increased, and now even government employees have to pay this extra 50 rupees.
This is where Dearness Allowance (DA) comes into play.
Now, the question is: how does the government calculate how much percentage DA should be increased in seventh Pay Commission? What data does the government use to increase DA, and what role does the CPI index play in calculating DA? All these are the questions.
How to Calculate DA in the 7th Pay Commission using the Consumer Price Index?
Before calculating DA, first understand two things, and then you will know how DA is calculated:
- Base Year (2001 Base)
- CPI (Consumer Price Index)
First, understand the base year—this refers to how much prices have increased since that year. The base year is 2001, which means we refer to the price levels from 2001 as the reference point.
The process starts by taking the CPI values for the last 12 months. These values are then added together and divided by 12 to get the average. This gives the average CPI for the last 12 months.
The second important concept is the CPI. The CPI tracks how much prices are increasing over time.
So, the first step is to calculate the average CPI for the last 12 months. Then, this value is converted to the 2001 base using the factor 2.88. Finally, the DA formula is applied.
Okay, let’s understand how DA is calculated ?
How DA is Calculated – Step-by-Step
| Step | Description | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Step 1: Calculate Average CPI for the Last 12 Months | • The Average CPI is calculated by adding up the CPI values of the last 12 months and dividing the total by 12. | |||||||||||||
| Step 2: Convert CPI to the 2001 Base |
• The average CPI (suppose 145.67) of the last 12 months is then converted to the 2001 base by multiplying it by the conversion factor of 2.88. 145.67 × 2.88 = 419.54 |

| Step 3: Calculate the Base CPI |
• The Base CPI represents the CPI value in the 2001 base year. The government sets this value at 261.42, which reflects the CPI for the base year (2001) adjusted for inflation. • In other words, this value is used as the reference to measure price changes. Base CPI = 261.42 (fixed value, set by the government) |

| Step 4: Apply the DA Formula |
• So, now that we have the Converted CPI (419.54) and the Base CPI (261.42), we can apply the formula to calculate DA. Formula:
Substitute the values:

| Step 5: Round to the Nearest Whole Number |
• Finally, we round the DA percentage to the nearest whole number. 60.49% → 60% |
