How to Calculate Cost Inflation Index
How to calculate cost inflation index involves a straightforward mathematical formula:
Step 1: Gather Required Information
- Identify the original purchase cost of your asset
- Note down the financial year when you purchased the asset
- Determine the financial year when you’re selling the asset
Step 2: Find CII Values
- Locate the CII value for your purchase year from the official CBDT table
- Find the CII value for your sale year from the same table
- Ensure you’re using the correct financial year values, not assessment year
Step 3: Apply the Indexation Formula
- Use the formula: Indexed Cost = Original Cost × (Sale Year CII ÷ Purchase Year CII)
- This calculation will give you the inflation-adjusted purchase cost
- The indexed cost will always be higher than your original purchase cost
Step 4: Calculate Capital Gains
- Subtract the indexed cost from your sale price
- This gives you the taxable capital gains after indexation benefit
- Compare this with gains without indexation to see your tax savings
Step 5: Verify Your Calculation
- Double-check your CII values from official sources
- Ensure you’ve used the correct financial years
- Consider consulting a tax professional for complex cases
Formula: Indexed Cost = Original Cost × (Sale Year CII ÷ Purchase Year CII)

| Particulars | Amount/Value |
| Property Purchase Cost (2015-16) | ₹50,00,000 |
| Sale Price (2023-24) | ₹1,20,00,000 |
| Purchase Year CII | 254 |
| Sale Year CII | 348 |
| Indexed Cost | ₹68,50,394 |
