When executing equity trades on Indian stock exchanges (NSE and BSE), the difference between your buying price and selling price does not represent your take-home profit. Every trade is subject to a mandatory sequence of regulatory, statutory, and broker fees that chip away at gross gains.
Even when using modern discount brokers that advertise zero brokerage on delivery orders, regulatory charges—most notably Securities Transaction Tax (STT), stamp duty, and exchange fees—must still be paid. This calculator itemizes every single charge on an equity trade, giving you your true net profit and exact break-even threshold.
What this calculator does
The Stock Brokerage Calculator computes your net profit or loss by aggregating all direct and indirect transaction costs:
- Brokerage: Flat-fee or percentage-based broker commission for delivery or intraday trades.
- Securities Transaction Tax (STT): Central government turnover tax levied on transaction value.
- Exchange transaction charges: Fees levied by NSE or BSE to process order matching.
- SEBI turnover charges: Regulatory fee paid to the Securities and Exchange Board of India (₹10 per crore).
- Stamp duty: State stamp duty levied on buy-side turnover under the Indian Stamp Act.
- GST: 18% Goods and Services Tax charged on brokerage, exchange fees, and SEBI charges.
- Break-even price move: The minimum price change per share required to clear all expenses.
How to use this calculator
- Buy price: Enter the executed purchase price per share.
- Sell price: Enter the target or executed sale price per share.
- Quantity: Enter the number of shares bought and sold.
- Segment: Choose Equity delivery (shares credited to Demat) or Equity intraday (positions squared off within the same trading session).
- Brokerage per order: Enter your broker's flat fee per executed order (typically ₹20 for discount brokers; enter ₹0 for free delivery brokers).
Verified calculation breakdown
Consider a delivery trade of 100 shares bought at ₹1,000 and sold at ₹1,100 through a standard discount broker:
| Charge / Component | Calculation Basis | Amount |
|---|---|---|
| Buy turnover (100 shares × ₹1,000) | Purchase value | ₹1,00,000 |
| Sell turnover (100 shares × ₹1,100) | Sale value | ₹1,10,000 |
| Total trade turnover | Buy + Sell | ₹2,10,000 |
| Gross trade profit | ₹1,10,000 − ₹1,00,000 | ₹10,000 |
| Brokerage | Discount broker delivery rate | ₹0 |
| Securities Transaction Tax (STT) | 0.1% on buy (₹100) + 0.1% on sell (₹110) | ₹210 |
| Exchange & SEBI turnover charges | NSE transaction fee + SEBI fee | ₹6.45 |
| Stamp duty | 0.015% on buy turnover only | ₹15.00 |
| GST @ 18% | 18% of (Brokerage + Exchange + SEBI fees) | ₹1.16 |
| Total statutory & trading charges | Sum of all fees | ₹233 |
| Net profit realized | Gross profit minus total charges | ₹9,767 |
| Break-even move required | Minimum price move to avoid loss | ₹2 per share |
In this trade, while the gross profit was ₹10,000, statutory charges reduced the realized profit to ₹9,767. More importantly, you needed the share price to rise past ₹1,002.33 just to cover trading friction.
Delivery vs Intraday charge structure
| Levy | Equity Delivery | Equity Intraday |
|---|---|---|
| Brokerage | ₹0 to ₹20 per order | Lower of ₹20 or 0.03% per executed order |
| STT | 0.1% on both Buy and Sell | 0.025% on Sell side only |
| Stamp Duty | 0.015% on Buy side | 0.003% on Buy side |
| GST | 18% on (Brokerage + Exchange + SEBI) | 18% on (Brokerage + Exchange + SEBI) |
| Depository (DP) Charges | ₹13.50 to ₹18.50 + GST on Sell leg | Nil (no demat movement) |
Frequently asked questions
Why do I still pay charges when my discount broker advertises zero brokerage?
Discount brokers offer ₹0 brokerage on equity delivery, but they cannot waive statutory government and regulatory levies. Every trade attracts Securities Transaction Tax (STT), state stamp duty, NSE/BSE exchange transaction fees, SEBI turnover charges, and 18% GST on non-STT fees.
How is STT calculated differently for delivery versus intraday trades?
For equity delivery trades, STT is charged on both buy and sell sides at 0.1% of turnover. For intraday equity trades, STT is charged only on the sell side at a reduced rate of 0.025% of sell turnover.
What is the break-even move indicated by this calculator?
The break-even move shows the exact minimum rupee increase per share required to cover all round-trip brokerage and statutory charges. If the stock does not rise by at least this amount, your trade results in a net financial loss even if the gross trade was positive.
Are stock trading charges tax-deductible against capital gains?
Brokerage, exchange transaction charges, and stamp duty can be added to your cost of acquisition or deducted from sale consideration when calculating capital gains. However, under Section 36(1)(xv) of the Income Tax Act, Securities Transaction Tax (STT) cannot be deducted from capital gains, though business traders declaring business income (speculative/non-speculative) can claim STT as an allowable business expense.
