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% ā 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 ā a 20% tax on gains, plus surcharge and cess, can erode a substantial portion of short-term profits.
The calculator shows:
- Capital Gain ā gross short-term profit
- STCG Tax ā 20% on the entire gain
- Surcharge ā based on total income (not capped for STCG, unlike LTCG)
- Cess ā 4% Health and Education Cess
- Total Tax Payable ā 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.

Formula & Methodology
Applicable law: Section 111A, Income Tax Act ā FY 2025-26 rates (Budget 2024) | Component | Rule | |---|---| | STCG rate | 20% (flat, on full gain ā no exemption) | | Surcharge | 10% (50Lā1Cr) / 15% (1ā2Cr) / 25% (2ā5Cr) / 37% (>5Cr) | | Cess | 4% on (tax + surcharge) | Calculation steps: 1.Capital Gain = Sale Value ā Purchase Value2.STCG Tax = Capital Gain Ć 20%3.Surcharge = STCG Tax Ć Surcharge Rate(based on total income) 4.Cess = (STCG Tax + Surcharge) Ć 4%5.Total Tax = STCG Tax + Surcharge + CessWorked example: Purchase ā¹5,00,000 ā Sale ā¹6,20,000 ā Gain ā¹1,20,000; annual income ā¹10 lakh. 1. 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 ā 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.
