Capital Gains Tax Calculator Comparison 2026: Which Free Tool Wins for Indian Users?

The actual decision: which capital gains calculator handles post-Budget 2024 rates correctly?

If you sold equity shares, redeemed mutual fund units, exited a property, or liquidated gold this financial year, you're trying to answer one specific question: how much tax do I owe on these gains for FY 2025-26? The answer changed materially after Budget 2024 — STCG on equity jumped to 20% under Section 111A, LTCG under Section 112A is now 12.5% with a ₹1.25 lakh exemption, and property sellers got a choice between 12.5% without indexation or 20% with indexation (for assets acquired before 23 July 2024).

Quick verdict: For a fast, browser-only calculation across asset types with the new rates already baked in, SabTools' Capital Gains Tax Calculator is the cleanest choice — no signup, no upsell pop-up, instant results. Quicko is the strongest competitor for active equity traders who want gains tied to broker imports. ClearTax wins if you need a deeply explained walkthrough but expect signup gates and filing-tier prompts. Tax2win sits in the middle, useful but pushes CA-assisted filing.

The rest of this post gets specific: same scenario fed into each calculator, where each one wins, and where the trade-offs hide.

What "capital gains tax calculator" actually needs to handle in 2026

A capital gains calculator is only useful if it knows the rules for your asset class. Post-Budget 2024, the rule set looks like this:

• Listed equity & equity mutual funds (Section 111A / 112A): STCG (held ≤12 months) taxed at 20%. LTCG (held >12 months) taxed at 12.5% on gains above the ₹1,25,000 annual exemption.
• Debt mutual funds (purchased after 1 April 2023): Taxed at slab rate regardless of holding period — no indexation, no LTCG benefit.
• Property / real estate (Section 112): LTCG threshold is 24 months. Tax is 12.5% without indexation. For properties acquired before 23 July 2024, sellers can choose 20% with indexation if it produces lower tax.
• Gold, unlisted shares, debentures: 24-month threshold, LTCG at 12.5% without indexation.
• Surcharge & cess: 4% Health & Education cess applies on top, plus surcharge if total income crosses ₹50L / ₹1Cr / ₹2Cr / ₹5Cr brackets.

If a calculator doesn't ask which asset class, when you bought, when you sold, and (for old property) which method you want to compare — it's giving you a guess. That filter alone eliminates a lot of generic tools.

Side-by-side: same scenarios across SabTools, ClearTax, Tax2win and Quicko

Let's run three real scenarios through each.

Scenario 1: Riya's equity portfolio (LTCG, Section 112A)

Riya, a Bangalore SaaS engineer, sold listed equity in October 2025 — bought for ₹4,00,000 in 2022, sold for ₹7,50,000. Holding period: 38 months → LTCG.

• Gain: ₹3,50,000
• Less ₹1,25,000 exemption (Section 112A): Taxable LTCG = ₹2,25,000
• Tax @ 12.5%: ₹28,125
• Plus 4% cess: ₹1,125 → Total ₹29,250

SabTools' Capital Gains Tax Calculator returns this in one screen — pick "Listed Equity / Equity MF", enter dates and amounts, see the exemption applied. Quicko's calculator arrives at the same ₹29,250 and additionally lets you import broker statements (useful if you have 50+ trades). ClearTax handles it correctly inside its filing flow but the standalone calculator nudges you toward signing up to "save your computation".

Scenario 2: Arjun's Pune flat (property LTCG, choice of methods)

Arjun bought a 2BHK in Hinjewadi in March 2018 for ₹62,00,000 (stamp duty + registration: ₹3,72,000, total cost ₹65,72,000). He sold in July 2025 for ₹1,05,00,000. Brokerage: ₹1,05,000.

Because the asset was acquired before 23 July 2024, Arjun gets to compare:

• Method A — 12.5% without indexation: Net gain ≈ ₹38,23,000 → tax ≈ ₹4,77,875 (+ cess)
• Method B — 20% with indexation: Indexed cost (CII 2024-25 = 363, CII 2017-18 = 272) ≈ ₹87,69,000 → indexed gain ≈ ₹16,26,000 → tax ≈ ₹3,25,200 (+ cess)

Method B saves Arjun ~₹1.5L. SabTools shows both methods side-by-side and highlights which produces lower tax — exactly the comparison the law gives you the right to make. Quicko handles property LTCG well but its primary UX is built for stocks; the property module asks for the same inputs but doesn't always foreground the dual-method comparison. ClearTax's main tax site has good explainer content on the choice but the standalone property gains calculator is buried inside their filing product.

Scenario 3: Meera's gold sale

Meera sold 80g of 22K gold in February 2026 that she'd inherited (cost basis = FMV on date of inheritance, March 2019: ₹2,40,000). Sale value: ₹6,40,000.

• Holding period: >24 months → LTCG
• Gain: ₹4,00,000
• Tax @ 12.5% (no indexation, post-23 July 2024): ₹50,000 + 4% cess = ₹52,000

SabTools handles this in the "Gold / Other LTCG" path. None of the competitor calculators got this materially wrong, but Tax2win and ClearTax kept prompting "Want a CA to file this for you?" mid-calculation, which is irritating when you just want a number. If you cross-reference the gold value, SabTools' Gold Price Calculator can sanity-check the sale figure against current 22K/24K rates before you compute the tax.

Where each calculator genuinely wins

ClearTax wins on regulatory depth

ClearTax is the most authoritative tax brand in India and it shows in their explainer content. If you're trying to understand Section 111A vs 112A vs 112 — not just compute — their long-form articles next to the calculator are well-edited and updated. Their Income Tax Calculator integrates capital gains into your overall tax position, which is genuinely useful at filing time. The trade-off is the constant push toward their paid filing tiers and the email gate when you want to save or download a computation.

Quicko wins on trader workflows

Quicko was built around stocks and F&O traders. Their Capital Gains Tax Calculator handles per-trade granularity, Zerodha/Upstox tax P&L imports, and intraday vs delivery treatment. If you have a few hundred trades a year and need to reconcile broker P&L statements, Quicko is a strong specialist tool. For a single sale or a handful of transactions, it's overkill.

Tax2win wins on assisted filing pipeline

Tax2win's strength isn't really the calculator — their Income Tax Calculator is competent but not differentiated. Where they help is the handoff: compute → talk to a CA → get returns filed. If you actually want a paid expert in the loop, their funnel is smoother than ClearTax's.

SabTools wins on speed, privacy and zero friction

The SabTools Capital Gains Tax Calculator is built for one job: enter your transaction details, get the right number under FY 2025-26 rules, move on. Specifically:

• Browser-only computation — your purchase/sale figures never leave your device. Useful when the numbers are sensitive (a property sale, a big equity exit) and you'd rather not paste them into a logged-in account.
• No signup, no email gate — no "create an account to save your result" wall.
• Indian formatting — lakhs and crores, ₹ symbol, Indian comma grouping. ₹1,05,00,000 displays correctly, not as 10,500,000.
• Dual-method property comparison — for pre-23-July-2024 assets, both 12.5% and 20%+indexation are shown in one view.
• No ad walls on the tool itself — guide articles carry ads, the calculator doesn't.

None of this means ClearTax or Quicko are bad. It means SabTools is optimised for a different reader: someone who wants a fast, accurate number without a tax-platform relationship.

Pricing, signups, and the friction tax

All four calculators are technically free to use. The differences are in what each platform asks of you.

Tool	Signup required?	Upsell during use?	Save/export
SabTools	No	None	Free download/print
ClearTax	For saving results	Filing tiers prompted	Behind email gate
Tax2win	For saving / CA chat	CA-assisted filing	Behind email gate
Quicko	For broker import	Filing/advisory plans	Account-bound

For a one-off computation — say, you sold one property this year and want to know your tax outflow before you file — SabTools' zero-friction model is the lowest-effort path. For ongoing portfolio reconciliation across hundreds of equity trades, Quicko's account-bound import is worth the signup.

Privacy and how your data is handled

Capital gains data is sensitive — sale proceeds reveal net worth, property exits reveal addresses, equity P&L reveals positions. The four tools handle this differently:

• SabTools: Calculations run client-side in JavaScript. The numbers you enter aren't transmitted to a server, aren't stored against an account, and aren't tied to a profile.
• ClearTax, Tax2win, Quicko: All three are full tax-filing platforms. Even when you use only the calculator, you're on their domain with analytics, and any "save" action ties data to an account. This isn't sinister — it's how SaaS works — but it's worth knowing.

If you're computing capital gains on, say, a ₹3Cr property sale, the privacy difference is meaningful. If you're working out tax on a ₹40,000 mutual fund redemption, less so.

The Section 54 / 54F angle most calculators skip

If you sold a property or other long-term asset, your tax bill isn't final until you've considered Section 54 (reinvest in another residential house) or Section 54F (sell other LTCG asset and buy a residential house). Post-Budget 2024, both exemptions are capped at ₹10 crore.

Most generic capital gains calculators stop at "here's your LTCG tax". SabTools pairs the capital gains tool with a dedicated Section 54 / 54F Exemption Calculator so Arjun (from Scenario 2) can model what happens if he reinvests ₹40L of his ₹38L gain into a new flat — exempting the entire gain. ClearTax discusses Sections 54/54F in articles, but doesn't have a focused interactive calculator at the same depth.

Common mistakes the calculators won't catch for you

Even the best calculator computes what you give it. A few things to verify yourself:

1. Holding period start date: For inherited assets, holding period runs from the original purchaser's date, not the inheritance date — but the cost basis becomes the FMV the previous owner paid.
2. Cost of improvement: For property, you can add genuine capital improvements (not repairs) to cost basis. Calculators give you a field; whether you use it correctly is on you.
3. Brokerage and STT: Brokerage is deductible from sale value. STT is not deductible for equity LTCG/STCG under 111A/112A — different rule from regular capital gains.
4. Set-off of losses: STCL can offset both STCG and LTCG; LTCL only offsets LTCG. A single-transaction calculator won't set this off — you do it at filing.
5. Surcharge cliffs: If your total income (including LTCG) tips over ₹50L, ₹1Cr, ₹2Cr, surcharge applies. Capital gains calculators usually compute the headline rate; surcharge is best handled in a full income-tax calculator.

Bottom line: when to pick which

• Pick SabTools' Capital Gains Tax Calculator if you want a fast, accurate FY 2025-26 number across asset classes without creating an account, especially for property's dual-method comparison. Pair it with the Section 54/54F calculator if reinvesting.
• Pick Quicko if you're an active trader with broker statements to reconcile and you're already going to file through them.
• Pick ClearTax if you want long-form regulatory explainers alongside the math and you don't mind the signup for saved results.
• Pick Tax2win if you intend to engage a CA for assisted filing and want a smooth handoff from calculation to consultation.

For most people computing one or two transactions before they file ITR-2, the friction-free path wins. While you're at it, the related SIP Calculator, EPF Calculator and RBI Bank Holidays 2026 Calendar are useful for tax-planning the rest of FY 2025-26 — when's the last working day to invest before 31 March, what's your projected EPF maturity, what does a fresh SIP do to your tax saving.
