What Indexation Does

Indexation adjusts your purchase cost for inflation using the government's Cost Inflation Index, so you pay long-term capital gains tax on the real gain rather than the inflation. The formula is simple: indexed cost = purchase cost × CII of the sale year ÷ CII of the purchase year. A ₹10 lakh purchase in FY 2014-15 (CII 240) sold in FY 2026-27 (CII 384) has an indexed cost of ₹16 lakh — ₹6 lakh of your paper gain is recognised as inflation and never taxed.

Where Indexation Still Applies

Budget 2024 removed indexation from most assets: since 23 July 2024, long-term gains are generally taxed at a flat 12.5% on the plain gain. The one live exception is land or a building bought before 23 July 2024 by a resident individual or HUF, who may choose 20% tax with indexation if that comes out lower. The capital gains calculator runs both methods side by side; this page is the reference for the index itself and the indexed-cost arithmetic.

Reading the Table

The base year is 2001-02 = 100, and the CBDT notifies one value each year — FY 2026-27 is 384, notified on 15 July 2026 (Notification No. 85/2026). For anything bought before 1 April 2001, use its fair market value on that date as the cost, with FY 2001-02 as the purchase year. Improvement costs index separately, each from the year it was spent.

FAQs about Indexation Calculator

384, notified by CBDT Notification No. 85/2026 dated 15 July 2026, applicable from 1 April 2026. The base year is 2001-02 = 100; FY 2025-26 was 376.
Indexed cost = purchase cost × CII of the sale year ÷ CII of the purchase year. Example: ₹10,00,000 bought in FY 2014-15 (CII 240), sold in FY 2026-27 (CII 384) → ₹10,00,000 × 384/240 = ₹16,00,000.
Only in one case: land/building bought before 23 July 2024, sold by a resident individual or HUF, who may choose 20% tax on the indexed gain over 12.5% on the plain gain. All other assets are taxed without indexation now.
Use its fair market value as on 1 April 2001 as the cost, and index from FY 2001-02 (CII 100). Keep a registered valuer's report for that FMV — it is what an assessing officer will ask for.
Yes, when the indexation route applies — each improvement indexes from the financial year it was actually spent, not the purchase year. The capital gains calculator takes improvement rows with their years for exactly this reason.
