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)

Practical Calculation Example

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
Capital Gains (Without Indexation)	₹70,00,000
