What is a STCG?
An STCG Tax Calculator computes the Income Tax liability on Short Term Capital Gains from equity shares and equity-oriented mutual funds under Section 111A of the Income Tax Act. For FY 2025-26, STCG on equity is taxed at a flat 20%, no exemption, no indexation, no slab rate benefit.
The Finance Act 2024 (Budget 2024) increased the STCG rate from 15% to 20% effective 23 July 2024. This makes short-term equity trading significantly more expensive from a tax standpoint, a 20% tax on gains, plus surcharge and cess, can erode a substantial portion of short-term profits.
The calculator shows:
- Capital Gain, gross short-term profit
- STCG Tax, 20% on the entire gain
- Surcharge, based on total income (not capped for STCG, unlike LTCG)
- Cess, 4% Health and Education Cess
- Total Tax Payable, the complete liability including all components
For equity held over 12 months, use the LTCG Tax Calculator. For overall income tax planning, use the Income Tax Calculator.
Why Use an STCG Tax Calculator?
Short-term equity profits look attractive until the tax bill arrives. A ā¹1,20,000 gain on a ā¹5,00,000 investment (24% return over 8 months) becomes just ā¹93,312 after tax for a person in the ā¹50Lāā¹1Cr income bracket (20% + 10% surcharge + 4% cess = 22.88%). The real return drops to 18.7%.
This calculator makes those post-tax numbers visible before selling, helping you decide whether it is worth waiting for LTCG treatment.
Who Should Use This Calculator?
Active equity traders, calculating quarterly advance tax obligations on short-term profits from delivery-based equity trades.
Mutual fund investors switching or redeeming early, understanding the tax cost of exiting equity funds within 12 months.
Investors comparing strategies, quantifying the benefit of waiting from STCG treatment to LTCG treatment (12.5% vs 20%, plus the ā¹1.25 lakh LTCG exemption).
Tax filers, ensuring the correct STCG amount is reported in Schedule CG of the ITR.
What Insights Does the STCG Tax Calculator Give You?
Capital Gain, the gross short-term profit from the equity transaction.
STCG Tax (20%), the base tax before surcharge and cess. Note: this applies to the entire gain, with no exemption.
Surcharge, for high-income taxpayers, the surcharge can add significantly, 25% surcharge on 20% STCG tax effectively raises the rate to 25%, plus cess.
Effective Tax Rate on Gain, the total tax as a percentage of the capital gain. Comparing this with the LTCG effective rate (often 7ā8% after exemption) quantifies the holding-period benefit.

Gain: ā¹1,20,000 2. STCG Tax: ā¹1,20,000 Ć 20% = ā¹24,000 3. Surcharge: 0% (income below ā¹50 lakh) 4. Cess: ā¹24,000 Ć 4% = ā¹960 5. Total tax: ā¹24,960, effective rate: 20.8% on gain Comparison with LTCG (same gain, held >12 months): Taxable LTCG = ā¹1,20,000 ā ā¹1,20,000 exemption = ā¹0 ā Zero tax. The 12-month holding difference saves the entire ā¹24,960 tax bill in this case.
