Understanding the Cost Inflation Index

The Cost Inflation Index (CII) is a number published by the Central Board of Direct Taxes (CBDT) for every financial year that is used to calculate capital gains on selling a capital asset like real estate, mutual funds, stocks or bonds.

The CII figure is published at the beginning of every financial year. It is used to rebase the purchase price of a capital asset, utilising the concept of indexation. The CII figure may be taken as a proxy for inflation. To understand how CII models inflation, have a look at how the value of ₹1,000 has changed over the years as per CII changes.

The incometax website has CII data from 1981 onwards. In this article we have shown the CII values since 1981 so that you can calculate the capital gains tax for assets purchased before 2001. Please note that the formal guidance, as per income tax laws, is to use the fair market value of the asset in 2001, as per the report from an approved assessor for capital gain tax purpose.

What is the value of something today that was ₹1000 in 1981?

The value of something that cost ₹1000 in FY 1981-82 would be around ₹ 15470 today.

Since the index started in FY 1981-82, we can think that the value of the Rupee has steadily decreased as per the change in the CII index. If the value of something was ₹100 when CII was 200, then that item should cost around ₹150 when CII rises to 300 (150 = 100 * 300/200). This is of course an approximation. The actual increase would depend on the product and the time period considered.

This result shows the impact of inflation very prominently. If the same trends continue for the next 40 years, then a ₹1 lakh/month lifestyle will jump to ₹15 lakhs per month. Our retirement corpus has to fund that lifestyle: Low-stress retirement planning calculations: worked out example.
