Cost Inflation Index (CII) Calculator with Improvement Indexation
Compute indexed cost of acquisition and improvement for capital gains — FY 2024-25 CII = 363
How it works
The calculator applies the CII for the acquisition year and, separately, the CII for the improvement year. It then compares the configured post-23 July 2024 options where the property grandfathering condition is selected.
FAQs
What is the CII formula?
Indexed Cost = Actual Cost × CII(sale year) / CII(purchase year or 2001-02, whichever is later)
How is improvement indexed?
Improvement cost is indexed using CII of the year in which the improvement was made (not the year of original purchase). Indexed improvement = Improvement Cost × CII(sale year) / CII(improvement year)
What is the FY 2024-25 CII?
CBDT Notification 44/2024-IT dated 24 May 2024 (F.No. 370142/17/2024-TPL) — CII for FY 2024-25 = 363
When does the grandfathering option apply?
For land or building (or both) acquired BEFORE 23 July 2024: taxpayer may compute tax under BOTH methods — (a) 12.5% without indexation OR (b) 20% with indexation — and pay whichever results in LOWER tax
How are inherited assets handled?
For inherited assets: period of holding of original owner is included. Cost of original owner is the cost of acquisition. CII is applied from the year of original acquisition (or 2001-02 if earlier).
