What is the Equity Capital Gains Tax Calculator?
An Equity Capital Gains Tax Calculator estimates the income tax you owe when you sell shares or equity mutual fund units at a profit. Since the Finance Act 2024 overhauled capital gains taxation effective 23 July 2024, the rules changed meaningfully for Indian equity investors — a higher LTCG rate, a larger exemption threshold, and a higher STCG rate than before — and many investors are still calculating their tax liability using outdated pre-2024 figures.
For listed equity shares and equity-oriented mutual funds, the tax treatment depends entirely on one variable: how long you held the investment before selling. Hold for more than 12 months and you qualify for Long-Term Capital Gains (LTCG) treatment, taxed at a flat 12.5% on gains exceeding a ₹1.25 lakh exemption per financial year. Sell within 12 months and the gain is Short-Term Capital Gains (STCG), taxed at a flat 20% with no exemption threshold at all — a rate roughly 60% higher than the previous 15% STCG rate that applied before July 2024.
This calculator focuses specifically on listed equity shares and equity mutual funds (not debt funds, real estate, or unlisted shares, which follow different rules), giving Indian retail investors a fast, accurate way to estimate the tax bite on a specific trade before deciding whether to sell now, wait past the 12-month mark, or harvest losses to offset gains elsewhere in their portfolio.
How does it work?
The calculator first computes your capital gain as sale value minus purchase value. It then checks the holding period: if you held the shares or mutual fund units for 12 months or less, the gain is classified as short-term and taxed at a flat 20% (revised upward from 15% by the Finance Act 2024, effective for transfers on or after 23 July 2024) — this rate applies to the entire gain, with no basic exemption.
If you held for more than 12 months, the gain is long-term. Long-term capital gains on listed equity and equity mutual funds enjoy an annual exemption of ₹1.25 lakh per financial year (raised from ₹1 lakh in the same Finance Act 2024 amendment) — meaning only gains above this threshold, aggregated across all your equity LTCG for the year, are taxed, at a flat 12.5% (up from 10% previously). If you have already booked other LTCG earlier in the same financial year, this calculator lets you enter that amount so it correctly reduces your remaining exemption for the current sale, since the ₹1.25 lakh threshold applies once per financial year across all equity LTCG combined, not per transaction.
Note that Securities Transaction Tax (STT) must have been paid on the transaction for these concessional rates to apply — true for virtually all trades executed on recognised stock exchanges like the NSE and BSE, and for mutual fund redemptions, but not for off-market transfers. Also note that these rates apply specifically to equity shares and equity-oriented mutual funds (funds with at least 65% allocation to Indian equities); debt mutual funds, international equity funds, and gold ETFs purchased after April 2023 are taxed entirely differently, at your income tax slab rate regardless of holding period.
Worked example
Consider Ananya, 31, a marketing manager in Chennai who bought ₹5,00,000 worth of a Nifty 50 index fund in March 2024 and sold the entire holding for ₹7,00,000 in November 2025 — a holding period of about 20 months, comfortably past the 12-month long-term threshold. Her capital gain is ₹2,00,000. She has not booked any other equity LTCG earlier in FY 2025-26, so her full ₹1,25,000 exemption is available. Taxable gain = ₹2,00,000 − ₹1,25,000 = ₹75,000, taxed at 12.5% = ₹9,375. Her net proceeds after tax come to ₹6,90,625, and her effective tax rate on the total ₹2,00,000 gain works out to just 4.7%, since most of it fell within the exemption.
Now compare this to her colleague Vikram, who bought a similar ₹5,00,000 position but sold it after only 8 months for the same ₹7,00,000, booking the identical ₹2,00,000 gain as short-term. With no exemption available and the flat 20% STCG rate, Vikram owes ₹40,000 in tax — more than four times Ananya's liability, purely because he sold four months earlier than the 12-month mark. This stark difference is precisely why many equity investors deliberately hold a position slightly longer, if their investment thesis allows it, to cross into long-term treatment before booking profits.
When to use this calculator
- 1Deciding whether to sell a profitable equity position now or wait until it crosses the 12-month long-term holding threshold, since the tax difference between STCG (20% flat) and LTCG (12.5% above ₹1.25 lakh exemption) can be substantial, as shown in the worked example above.
- 2Tax planning near the end of a financial year (January–March) to decide how much LTCG to book this year versus next, spreading gains across financial years to make full use of the ₹1.25 lakh exemption each year rather than triggering a large one-time tax hit.
- 3Estimating advance tax liability if you have booked or plan to book significant equity gains during the year, since capital gains are subject to advance tax rules and a shortfall can attract interest under Sections 234B and 234C of the Income Tax Act.
- 4Comparing the after-tax return of an equity investment against a debt instrument or fixed deposit, where interest is taxed at your full slab rate — equity's concessional LTCG/STCG rates often make it more tax-efficient even before considering its typically higher pre-tax returns.
- 5Deciding whether to harvest a loss-making position to offset gains elsewhere in your portfolio (tax-loss harvesting) — short-term capital losses can be set off against both STCG and LTCG, while long-term capital losses can only be set off against LTCG, under Section 70 of the Income Tax Act.
Common mistakes to avoid
- ✕Using the pre-July-2024 rates (15% STCG, 10% LTCG, ₹1 lakh exemption) that many investors still remember — the Finance Act 2024 raised these to 20% STCG, 12.5% LTCG, and a ₹1.25 lakh exemption for transfers made on or after 23 July 2024, a change that materially affects tax planning done using outdated figures.
- ✕Forgetting that the ₹1.25 lakh LTCG exemption applies once per financial year across all equity and equity mutual fund gains combined, not per stock or per transaction — an investor booking ₹80,000 LTCG from one stock and ₹90,000 from another has ₹1,70,000 total LTCG, of which only ₹45,000 is taxable, not zero.
- ✕Applying equity capital gains rates to debt mutual funds, international funds, or gold ETFs bought after April 2023 — these are taxed at your full income slab rate regardless of holding period under rules introduced by the Finance Act 2023, a completely different regime from listed equity.
- ✕Ignoring the holding period boundary precisely — 12 months and 1 day makes a transaction long-term, while exactly 12 months or less keeps it short-term; investors who sell a day or two early to "lock in profit" sometimes needlessly convert a lower-tax LTCG sale into a higher-tax STCG one.
- ✕Not netting short-term and long-term losses against gains before estimating tax owed — Indian tax law allows capital losses (short-term against both STCG and LTCG; long-term only against LTCG) to be carried forward for up to 8 assessment years if not fully absorbed in the current year, a valuable provision many investors forget to use.
Frequently asked questions
- What is the current LTCG tax rate on shares and equity mutual funds in India?
- As of the Finance Act 2024, effective for transfers on or after 23 July 2024, long-term capital gains (holding period over 12 months) on listed equity shares and equity-oriented mutual funds are taxed at a flat 12.5%, applicable only on gains exceeding ₹1.25 lakh in a financial year. Gains up to ₹1.25 lakh in a financial year, aggregated across all your equity LTCG, are entirely exempt from tax.
- What is the STCG tax rate on shares in India?
- Short-term capital gains (holding period of 12 months or less) on listed equity shares and equity mutual funds are taxed at a flat 20%, effective for transfers on or after 23 July 2024 under the Finance Act 2024 — up from 15% previously. This rate applies to the entire gain with no exemption threshold, and is charged regardless of your income tax slab.
- Do I need to pay STT for these concessional capital gains rates to apply?
- Yes. The concessional 20% STCG and 12.5% LTCG rates apply only where Securities Transaction Tax (STT) has been paid on the transaction. This is automatically true for essentially all trades executed through recognised stock exchanges (NSE, BSE) and for redemption of equity mutual fund units through a fund house or registrar. Off-market transfers of shares, such as gifting or transferring between demat accounts without a market sale, do not attract STT and are governed by different tax provisions.
- Can I set off capital losses from shares against my salary income?
- No. Capital losses — short-term or long-term — cannot be set off against salary, business, or other heads of income under the Income Tax Act. Short-term capital losses can be set off against both short-term and long-term capital gains in the same year. Long-term capital losses can only be set off against long-term capital gains. Any unabsorbed loss can be carried forward for up to 8 assessment years, provided you file your income tax return before the due date in the year the loss arises.
- Does this calculator account for grandfathering rules for shares bought before 2018?
- No. This calculator computes tax on the straightforward gain (sale value minus purchase value) under the current Finance Act 2024 rules. If you acquired equity shares or equity mutual fund units on or before 31 January 2018, special grandfathering provisions under Section 112A may let you use the higher of the actual cost or the fair market value as of 31 January 2018 as your effective purchase price, which can reduce your taxable gain. If your holdings predate 2018, consult a chartered accountant or use your broker's capital gains statement, which typically applies grandfathering automatically for such trades.
