What this number actually does
When you sell a property you pay tax on the profit. But some of that profit is not real gain, it is just inflation. A rupee in 2001 bought far more than a rupee today.
The government accepts this, so it publishes an index that lets you scale up your original cost. Your cost goes up on paper, your profit goes down, and you pay tax on the real gain rather than on inflation.
The sum, with a real example
The base year 2001 to 2002 is set at 100. Every later year is higher.
Adjusted cost = your cost × (index for the year you sell ÷ index for the year you bought)
So if a property cost you ten lakh rupees in 2001 and you sell it in 2026-27:
Ten lakh × (384 ÷ 100). The third column in the table above gives you that multiplier directly.

When the index is updated
The government announces the figure for each financial year, usually part way through it. We update this page and every calculator on the site as soon as it is published, so what you see here is the current number.
Questions people ask us
- Why is 2001 the base year?
The government reset the base to 2001 and set it at 100. It also allows anyone who bought before April 2001 to use the property's 2001 value as their cost. The two things go together.
- Does this apply to everything I sell?
It applies to long term capital assets such as property held for a qualifying period. Different rules apply to shares and mutual funds, and the rules changed recently for some assets. Ask your accountant about anything other than property.
- What if I bought in a year not shown?
Anything before April 2001 uses the base of 100, and you use the 1 April 2001 value as your cost. That is why the table starts there.
