The Index Cost of Acquisition Calculator is a financial tool used primarily for capital gains tax calculations. It helps individuals determine the inflation-adjusted cost of a long-term capital asset. This is particularly relevant in countries like India, where indexation benefit is allowed to account for inflation when calculating capital gains on the sale of assets like property, gold, or other investments held for more than two years.
When assets are held over time, inflation can erode their value. The income tax authorities allow adjusting the cost of acquisition based on inflation to ensure a fair and accurate gain calculation. This adjusted cost is called the indexed cost of acquisition, and calculating it manually can be tedious—especially when index values vary every year.
The Index Cost of Acquisition Calculator automates this process, saving you time and ensuring precision in your tax computation.
How to Use the Index Cost of Acquisition Calculator
Using this calculator is simple and requires only three inputs:
- Actual Purchase Price (Cost of Acquisition)
- Financial Year of Purchase
- Financial Year of Sale
Based on these inputs, the calculator will compute the Indexed Cost of Acquisition, which is used in capital gains tax calculations.
Step-by-Step Instructions:
- Enter the actual purchase price of the asset.
- Select or input the financial year when the asset was purchased.
- Select or input the financial year in which the asset is sold.
- Click Calculate to get the indexed cost of acquisition.
Index Cost of Acquisition Formula (in simple text)
To calculate the Indexed Cost of Acquisition, use this formula:
Indexed Cost = (Purchase Price × CII of Sale Year) / CII of Purchase Year
Where:
- CII stands for Cost Inflation Index
- CII values are released by the Income Tax Department every financial year
- Purchase Price is the original cost of acquiring the asset
The indexed cost is then used in this capital gain formula:
Long-Term Capital Gain = Sale Price – Indexed Cost of Acquisition
Example Calculation
Let’s assume the following scenario:
- You bought a property in Financial Year 2005-06 for ₹10,00,000
- You sold it in Financial Year 2023-24
- The CII for 2005-06 is 117
- The CII for 2023-24 is 348
Step 1: Use the formula
Indexed Cost = (10,00,000 × 348) / 117
Indexed Cost = 34,80,000 / 117 = ₹29,74,359
So, the inflation-adjusted cost of your property is ₹29,74,359.
If you sold the property for ₹60,00,000, your long-term capital gain is:
Capital Gain = 60,00,000 – 29,74,359 = ₹30,25,641
This is the amount on which tax is payable, subject to exemptions if applicable.
Why Use an Index Cost of Acquisition Calculator?

Additional Information
What is CII (Cost Inflation Index)?
The Cost Inflation Index is a measure of inflation released by the Income Tax Department annually. It is used to adjust the purchase price of an asset to account for inflation, which then helps in calculating accurate long-term capital gains.
Recent CII Values:
- FY 2023-24: 348
- FY 2022-23: 331
- FY 2021-22: 317
- FY 2020-21: 301
- FY 2019-20: 289
(These values change every year.)

Anyone selling a long-term asset like property, gold, or mutual funds.
3. What is the benefit of indexation?
Indexation reduces your taxable capital gain by increasing your asset’s cost based on inflation.
4. What is the Cost Inflation Index (CII)?

8. How is capital gain calculated using indexed cost?
Capital Gain = Sale Price – Indexed Cost of Acquisition
9. Do I pay less tax using indexation?
Yes. Since the gain amount reduces, your tax liability is also lower.
10. Can NRIs use indexation?
Yes, in many cases. But rules may differ; consult a tax advisor.

You may need to estimate or obtain historical records to compute accurately.
16. Is indexation automatic when filing taxes?
No, you must calculate and report it manually or using software/tools.
17. What if the CII is not declared for the latest year yet?
Use the latest available CII or wait until it is published.
18. What if the asset was improved or renovated?
Cost of improvement can also be indexed using the same principle.
19. Is indexation different for different asset types?
No, the concept is the same, though holding periods and tax rates may differ.
20. Can I use indexation for multiple assets at once?
Yes, you can calculate separately for each asset based on their individual purchase and sale years.
