About the Cost Inflation Index (CII) Calculator
The Cost Inflation Index (CII) lifts the cost of an asset to today’s prices, so you are taxed on the real gain rather than on inflation. This page has the official CII table from 2001-02 (100) to 2026-27 (384) — the 2026-27 figure was notified under section 72(8)(a) of the Income-tax Act, 2025 — and a calculator for the indexed cost of acquisition and of each improvement.
Enter when you bought (or when the previous owner bought, if you inherited), when you sold, the cost and any improvements. You get the indexed cost, the gain with and without indexation and the flat tax both ways, and a plain answer to the question that matters since 23 July 2024: can you still use indexation for this sale? Everything is calculated in your browser.
How to use it
- Choose what you sold and who is selling. The 20%-with-indexation choice is only for land or buildings sold by a resident individual or HUF.
- Pick Bought or built, or Inherited or gift. For an inherited asset, enter the date and cost of the previous owner, and the date you received it.
- Enter the date bought, the date sold and the cost. If it was bought before 1 April 2001, you can enter its fair market value on that date (and, for land or buildings, the stamp duty value that caps it).
- Add any improvements — capital work such as an extension — with the financial year the work was done.
- Optionally enter the sale price and transfer expenses to compare the gain and tax with and without indexation. Copy the summary or download the breakdown as CSV; the full CII table can be copied or downloaded too.
Examples
Improvement ₹3 lakh in 2015-16 · transfer expenses ₹50,000 · resident individual
Indexed cost ₹57,48,503 (₹25,00,000 × 384 ÷ 167) · indexed improvement ₹4,53,543 · gain with indexation ₹32,47,954, without ₹66,50,000
20% of the indexed gain is ₹6,49,591; 12.5% of the plain gain is ₹8,31,250. The lower one applies, saving ₹1,81,659 before surcharge and cess.
Cost ₹4 lakh · stamp duty value on 1 April 2001 ₹7 lakh
Cost taken as ₹7,00,000 (the value on 1 April 2001, capped at the stamp duty value) · indexed cost for a 2026-27 sale ₹26,88,000
Transfer expenses ₹50,000 · no improvements
12.5% without indexation (₹3,68,750) is lower than 20% with it (₹4,65,862) — with only three years of inflation, indexation does not help
How indexation works
Indexed cost of acquisition = cost × CII of the year of sale ÷ CII of the base year. The base year is the first financial year in which the asset was held, or 2001-02 if it was bought earlier (section 72(8)(b) of the Income-tax Act, 2025; Explanation (iii) to section 48 of the 1961 Act). Each improvement is indexed from the year the work was done (section 72(8)(c)).
For an asset held since before 1 April 2001 you may use its fair market value on 1 April 2001 instead of the cost (section 90(9)); for land or buildings that value cannot exceed the stamp duty value on that date (section 90(10)), and improvement work done before 1 April 2001 does not count (section 90(1)(b)). The Central Government notifies the index for each year having regard to 75% of the average rise in the Consumer Price Index (urban) for the year before (section 72(8)(a)).
When indexation still applies
From 23 July 2024, long-term capital gains are taxed at 12.5% without indexation. One exception remains: a resident individual or HUF selling land or a building acquired before 23 July 2024 pays the lower of 12.5% of the gain without indexation and 20% of the gain with indexation — section 197(3) of the Income-tax Act, 2025 for sales from 1 April 2026, and the second proviso to section 112(1)(a) of the 1961 Act for sales from 23 July 2024 to 31 March 2026.
Non-residents, companies and firms, and anyone selling other assets — gold, jewellery, unlisted shares, debt funds bought before 1 April 2023 — no longer get indexation. For sales before 23 July 2024, long-term gains on these assets were taxed at 20% after indexation (a non-resident’s unlisted shares at 10% without it), so the indexed cost is still the figure for those returns. Land or buildings are long-term after 24 months (36 months for sales before 1 April 2017).
Inherited and gifted property
If you inherited or were gifted an asset, its cost is what the previous owner paid (section 73), and their holding period counts as yours. Indexation then runs from the year the previous owner first held it, as the Bombay High Court held in CIT v. Manjula J. Shah; the calculator also shows the figure from the year you received it, because the Act’s words — “the first year in which the asset was held by the assessee” — can be read that way too. If you received the property on or after 23 July 2024, it is not settled whether it counts as “acquired before 23 July 2024” for the 20% option — the page flags this case.
The official sources
CII 2026-27 = 384: Notification S.O. 3889(E), which applies from tax year 2026-27. CII 2001-02 to 2025-26: the table in the CBDT’s ITR-2 utility for assessment year 2026-27. Rules: the Income-tax Act, 2025, sections 72, 73, 90 and 197.
Limitations
- The tax shown is the flat 12.5% or 20% on the gain — before surcharge, the 4% cess, any unused basic exemption limit and reinvestment exemptions (sections 82, 85 and 86; 54, 54EC and 54F of the 1961 Act). Use the capital gains tax calculator for the full tax for the year.
- Holding periods are checked for land or buildings, and for other assets sold from 23 July 2024. For older sales of other assets the calculator only knows that up to 12 months was short-term and more than 36 months long-term; in between, the rule depended on the asset and the year.
- Bonds and debentures never had indexation (except capital indexed bonds and Sovereign Gold Bonds), and debt mutual fund units bought from 1 April 2023, market-linked debentures and unlisted bonds sold from 23 July 2024 give short-term gains whatever the holding period (section 76; 50AA of the 1961 Act). This calculator is not for them.
- Assets acquired by the special modes in section 73 other than inheritance and gift (for example on a partition or a company’s liquidation) can have different cost rules.
- Indexation needs the year of each cost. If you do not know when a payment was made, use the year the asset was bought for the cost and the year of the work for improvements.

Frequently asked questions
What is the cost inflation index for 2026-27?
384, notified by the CBDT (S.O. 3889(E)) under section 72(8)(a) of the Income-tax Act, 2025. It was 376 for 2025-26 and 363 for 2024-25; the base year 2001-02 is 100.
Is indexation still allowed after the 2024 Budget?
Only in one case: land or buildings acquired before 23 July 2024 and sold by a resident individual or HUF. Such a seller pays the lower of 12.5% without indexation and 20% with indexation. Everyone else pays 12.5% on the gain without indexation for sales from 23 July 2024.
How do I calculate the indexed cost of acquisition?
Multiply the cost by the CII of the year of sale and divide by the CII of the year you bought it (or of 2001-02 if you bought it earlier). For a flat bought in 2010-11 for ₹25 lakh and sold in 2026-27: ₹25,00,000 × 384 ÷ 167 = ₹57,48,503.
What if I bought the property before 2001?
You can take its fair market value on 1 April 2001 as the cost, if that is higher than what you paid. For land or buildings that value cannot be more than the stamp duty value on 1 April 2001. Indexation then starts from 2001-02, with an index of 100.
Which year do I use for an improvement?
The financial year in which the work was done and paid for. Each improvement is indexed separately: amount × CII of the year of sale ÷ CII of that year. Repairs and routine maintenance are not improvements.
Is 20% with indexation always better than 12.5% without it?
No. Indexation helps most when the asset was held for a long time. For a recent purchase the indexed cost rises only a little, and 12.5% of the larger plain gain can be the lower tax. The calculator compares both and picks the lower one when you have the choice.
