CII Calculator (India) – Indexed Cost & LTCG
Use this cost inflation index calculator to estimate indexed cost of acquisition, indexed improvement cost, long-term capital gain (LTCG), and indicative tax.
What is a CII Calculator?
A CII calculator (Cost Inflation Index calculator) helps you adjust historical purchase and improvement costs for inflation when computing long-term capital gains in India. Instead of comparing old rupee values with current sale prices directly, the indexation method brings costs to present value using notified CII numbers.
This gives a more realistic taxable gain, especially for assets held over many years. In practical terms, a cost inflation index calculator can reduce taxable LTCG when inflation has been significant.
Why Cost Inflation Index Matters
- Fair taxation: You are taxed on real gains, not purely inflation-driven price changes.
- Lower taxable LTCG: Indexed acquisition and improvement costs generally increase with time.
- Better planning: Useful for estimating taxes before selling property or certain long-term assets.
- Compliance: Helps prepare numbers used in return filing and discussions with your CA.
Formula Used in This CII Calculator
Once LTCG is calculated, this tool also shows an indicative tax estimate at 20% plus 4% cess. Actual tax can differ based on exemptions, set-offs, and law changes.
Quick Example
| Input | Value |
|---|---|
| Purchase Cost | ₹30,00,000 (FY 2009-10, CII 148) |
| Sale Consideration | ₹95,00,000 (FY 2025-26, CII 376) |
| Transfer Expenses | ₹75,000 |
| Improvement Cost | ₹4,50,000 (FY 2016-17, CII 264) |
Using indexation, purchase and improvement costs increase materially. The resulting taxable long-term capital gain is usually much lower than a simple sale minus purchase comparison.
How to Use This LTCG & Indexed Cost Calculator
1) Enter your sale details
Add total sale consideration and deductible transfer expenses such as brokerage and legal fees.
2) Enter cost of acquisition
Provide original purchase value (or eligible fair market value for older assets, where applicable) and select purchase FY.
3) Add improvement details (if any)
If you made capital improvements, enter the amount and corresponding financial year.
4) Select sale FY and calculate
The calculator fetches CII values and displays indexed costs, net sale value, LTCG or long-term capital loss, and indicative tax.
Important Notes Before Filing
- CII values are notified by the Income Tax Department and can change with updates for future years.
- Different asset classes may have different LTCG rules and holding periods.
- Exemptions (such as reinvestment routes under eligible sections) are not auto-applied here.
- For assets acquired before the current base year framework, valuation rules may apply.
- Always verify final numbers with a chartered accountant before return filing.

No. This tool shows a simple estimate at 20% plus 4% cess. Surcharge and other specific adjustments are not included.
Is this a replacement for professional advice?
No. Treat this as an educational planning tool for cii calculator, indexed cost calculator, and long-term capital gain estimation. Use a professional review for final tax filing.
