Capital Gains Calculator (Equity Shares & Mutual Funds)

A capital gain is the difference between what you receive for selling listed equity shares or equity-oriented mutual fund units and what you originally paid for them (their cost of acquisition). Indian tax law splits this gain into short-term (STCG) or long-term (LTCG) depending on how long the specific units were held, and taxes each category differently — a flat rate for STCG under section 111A, and a flat rate after a pooled annual exemption for LTCG under section 112A.

The Finance (No. 2) Act, 2024 raised the section 111A STCG rate to 20% and the section 112A LTCG rate to 12.5% (without indexation), and raised the section 112A annual exemption to ₹1,25,000, effective for transfers on or after 23 July 2024. Sources were reviewed on 2026-07-24 and confirm these figures unchanged through FY 2026-27.

1. Choose listed equity shares or equity-oriented mutual fund units — this only changes labeling; the tax treatment is identical.
2. Add one row per purchase lot: the purchase date, the number of units, and the cost per unit.
3. For any lot purchased before 2018-01-31, also enter the fair market value per unit as on that date — the calculator only asks for this when a lot's date requires it.
4. Enter the single sale event: the sale date, total units sold, and sale price per unit.
5. The calculator matches your sale against lots oldest-first automatically — you do not need to specify which lot is being sold.

The units sold are matched against your purchase lots in first-in-first-out (FIFO) order by purchase date, regardless of the order you entered them in. The oldest lot is consumed first; once it is fully used up, the next-oldest lot is consumed, and so on until the total units sold is reached.

1. Sort all lots by purchase date, oldest first.
2. Subtract matched units from each lot in turn until the units sold is fully accounted for; a lot may be matched only partially if it is the last one needed.
3. Classify each matched lot independently: a sale on or before the date exactly 12 months after that lot's purchase date is short-term (111A); any later sale is long-term (112A).
4. Apply grandfathering to a matched lot's cost basis if it qualifies (see below), then compute that lot's gain as matched units × (sale price − effective cost per unit).

For a lot acquired before 2018-01-31, the cost of acquisition used for its LTCG computation is not simply what you paid. It is the higher of (a) the actual cost, and (b) the lower of (i) the fair market value (FMV) as on 2018-01-31, and (ii) the sale price. This can only raise the cost basis relative to the actual cost — it can reduce or eliminate the taxable gain that had already accrued before section 112A began taxing equity LTCG, but it can never turn a real gain into a deductible loss.

The ₹1,25,000 exemption under section 112A applies once against the total of all your LTCG-classified gains in a financial year — not separately for each lot, and not separately for each sale. This calculator sums every matched lot's gain that is classified as long-term into a single pooled figure, applies the exemption against that pool, and taxes only the remainder at 12.5%. Short-term gains are pooled the same way but receive no exemption at all — the full section 111A rate applies to the entire pooled STCG total.

• See exactly which of your purchase lots the sale draws from under FIFO, before you place the trade.
• Understand how much of an older holding's gain is protected by grandfathering.
• Check whether a sale's pooled LTCG will exceed the annual exemption, and by how much.
• Compare a scenario with different mixes of short-term and long-term lots side by side.

• Assuming the ₹1,25,000 exemption resets for every sale, instead of once per financial year across all equity LTCG transactions.
• Entering a fair market value for a lot purchased on or after 31 January 2018, where grandfathering does not apply at all.
• Manually picking which lot to treat as 'sold' instead of letting FIFO (oldest lot first) decide, which is what the law requires regardless of broker statements.
• Treating the calculator's total tax as your complete tax bill, when surcharge, cess, and your slab-rate liability on other income are not included.
• Forgetting that a purchase date must be on or before the sale date for every lot — a future-dated lot cannot be matched against a past sale.

• Confirm STT was actually paid on the transaction — off-market transfers and certain overseas trades may not qualify for these sections at all.
• Get the exact fair market value as on 31 January 2018 from your broker, registrar, or fund house for any pre-2018 holding, rather than estimating it.
• Track your cumulative LTCG across every equity sale in the financial year, not just the one entered here, before assuming the exemption is fully available.
• Recheck the current STCG/LTCG rates and exemption against an official source close to your filing date, since a future Budget can change them.

This calculator does not compute surcharge, health-and-education cess, or Section 87A rebate interaction; does not model capital loss carry-forward or set-off against other income; does not verify STT payment or broker records; does not track LTCG used elsewhere in the same financial year against the pooled exemption; and does not cover debt mutual funds, real estate, gold, unlisted shares, or any other capital-gains asset class, all of which follow different provisions.
