How to Use the Capital Gains Tax Calculator
Add each asset sale as a separate transaction — select the asset type (equity shares, equity mutual funds, debt funds, property, gold, or VDA/crypto), enter the purchase date, sale date, purchase price and sale price. The calculator automatically classifies each transaction as short-term (STCG) or long-term (LTCG) based on the holding period, applies the correct Budget 2024 tax rate for each category, computes indexation benefit where eligible, and nets off any capital losses against gains before showing your total capital gains tax liability and the option to apply Section 54/54EC/54F exemptions.
Capital Gains Tax Formula (FY 2025-26)
STCG (Equity, ≤12 months) = 20% × (Sale Value − Cost)
LTCG (Property, pre-Jul-2024 purchase) = min[ 20% × (Sale − Indexed Cost), 12.5% × (Sale − Cost) ]
LTCG (Property, post-Jul-2024 purchase) = 12.5% × (Sale Value − Cost), no indexation
Indexed Cost = Cost of Acquisition × (CII of Sale Year ÷ CII of Purchase Year)
Estimated CG Tax = (STCG Tax + LTCG Tax) × (1 + Surcharge%) × 1.04 (Cess)
Rates reflect Budget 2024 changes effective July 23, 2024. Indexation (CII) benefit is available ONLY for qualifying land/building (property) under the Finance Act 2024 grandfathering provision — individual/HUF, acquired before 23 July 2024 and transferred on or after that date, who may choose the lower of 12.5% without indexation or 20% with indexation. Gold has NO indexation: gold LTCG (holding > 24 months) is taxed at 12.5% with no indexation benefit from AY 2025-26. Unlisted shares have NO indexation: unlisted equity LTCG is taxed at 12.5% from AY 2025-26. Equity STCG/LTCG never qualifies for indexation. Section 54/54EC/54F exemptions can reduce taxable LTCG on property to zero if proceeds are reinvested as per the holding rules — see our Capital Gains Tax guide for worked examples.

Methodology, assumptions and sources
Scope: Computes short-term and long-term capital gains tax on the sale of equity shares, equity mutual funds, debt funds, real estate, gold and other capital assets, applying the holding-period test and (where applicable) indexation or grandfathering.
Calculation logic
- Determine the holding period (purchase date to sale date) and compare it against the asset-specific short/long-term threshold (e.g., 12 months for listed equity/equity MF, 24 months for immovable property and unlisted shares).
- For long-term equity/equity-MF gains, apply the Section 112A grandfathering rule: cost of acquisition is the higher of actual cost or the fair market value as of 31 January 2018 (capped at the actual sale value).
- For long-term gains on property/gold/other non-equity assets, apply Cost Inflation Index (CII) indexation where the asset qualifies, per current CBDT indexation rules.
- Apply the applicable tax rate for the asset class and holding-period bucket (STCG/LTCG) and compute tax payable, including cess and surcharge where relevant.
Inputs and assumptions
- Holding period, indexation eligibility and applicable rates follow the law in force for the assessment year selected.
- Indexation is not available for all asset classes post the Finance Act 2024 changes — the calculator applies the current, asset-specific rule rather than a single blanket rate.
Exclusions and edge cases
- Does not compute set-off/carry-forward of capital losses across years — that requires the full ITR schedule.
- Slump sale, business reorganisation and specific exemption computations (Sections 54/54F/54EC) are handled by the dedicated Capital Gains Exemption calculator, not here.
