Stock Brokerage Calculator

Every equity trade in India carries charges beyond the screen price — brokerage, STT, exchange fees, stamp duty and GST all nibble at your profit. Many traders notice this only when a "profitable" trade barely breaks even.

The Stock Brokerage Calculator adds up every statutory and broker charge on a buy-sell pair so you know your real, net profit or loss before you place the order. It works for both delivery and intraday equity trades, which are taxed and charged differently.

Frequent and intraday traders feel this most, since even a broker's "zero brokerage" claim on delivery still leaves STT, stamp duty and GST on the table.

What is the Stock Brokerage Calculator?

It is a tool that computes all the costs attached to buying and selling shares on the NSE or BSE — brokerage, Securities Transaction Tax (STT), exchange transaction charges, SEBI turnover fees, stamp duty and GST — and nets them off against your gross profit or loss.

The output tells you the exact rupee amount you keep after every charge, and the minimum price move per share you need just to cover costs.

How the calculator works

You enter the buy price, sell price and quantity of shares, choose the segment (equity delivery or equity intraday), and specify the brokerage your broker charges per order. The calculator applies the applicable rate structure for each charge based on the segment you pick, since delivery and intraday trades are taxed differently under Indian exchange rules.

It then sums the charges, subtracts them from your gross profit, and shows a full breakdown so you can see which charge is the biggest drag on your returns.

Formula

Calculation method (step by step)

1. Enter the buy price, sell price and quantity of shares traded.
2. Select the segment — equity delivery or equity intraday.
3. Enter the brokerage your broker charges per executed order.
4. The calculator computes turnover, then applies STT, transaction charges, SEBI fee, stamp duty and GST for that segment.
5. It subtracts total charges from your gross profit to show net profit or loss, along with the break-even price move per share.

Real-life example

Suppose you buy 100 shares of a stock at ₹1,000 and sell them at ₹1,100 as a delivery trade, with a broker charging ₹20 per order (capped at 0.03% for intraday, but zero for delivery at most discount brokers).

The charges look small individually, but they still shave nearly 2.3% off the gross profit — worth knowing before you plan your exit target.

Benefits

• Shows your true, after-charges profit instead of the misleading gross figure.
• Helps intraday traders see whether frequent trading is actually cost-effective.
• Reveals the break-even price move needed just to cover charges.
• Useful for comparing brokers with different flat-fee or percentage-based pricing.

Limitations

• Uses standard discount-broker rates; full-service brokers charge higher percentage-based brokerage.
• Does not include demat AMC, call-and-trade fees or auto square-off penalties.
• Ignores capital gains tax, which is calculated separately based on your holding period.
• Figures are educational estimates and can vary slightly by broker and exchange.

Who should use it

Intraday and swing traders who want to know their real cost per trade, delivery investors curious about total statutory charges, and anyone comparing brokers before opening a trading account will find this useful.

Common mistakes to avoid

• Ignoring STT and stamp duty because they seem small on a single trade — they add up over dozens of trades.
• Assuming "zero brokerage" means zero cost; statutory charges still apply.
• Not accounting for GST on brokerage and transaction charges.
• Forgetting that intraday STT applies only on the sell side, while delivery STT applies on both legs.

Expert tips

• Track your break-even price move per trade; if it exceeds your typical target, the strategy may not be viable.
• Compare a few brokers' full charge structures, not just the advertised brokerage.
• Batch smaller trades into fewer, larger ones when possible to reduce the fixed-cost drag.
• Keep contract notes; charges shown here should match them closely.

Frequently asked questions

Is brokerage really zero for delivery trades?

Most discount brokers charge zero brokerage on equity delivery trades, but you still pay STT, exchange transaction charges, SEBI fees, stamp duty and GST. These statutory charges cannot be waived by any broker and apply on every trade.

Why is STT different for delivery and intraday?

STT for delivery trades is charged on both the buy and sell legs at 0.1% of turnover, while intraday STT is charged only on the sell side at 0.025%. This reflects the different tax treatment exchanges apply to speculative versus investment trades.

Does this calculator include income tax on my profit?

No, it only calculates trading charges like brokerage, STT and GST. Capital gains tax on your profit depends on your holding period and is calculated separately using the applicable short-term or long-term capital gains rules.

Why do charges differ slightly across brokers?

Statutory charges like STT, stamp duty and SEBI fees are fixed by regulation, but brokerage itself varies by broker — flat fee, percentage-based, or a hybrid cap. Always check your broker's exact charge structure for precise figures.

What is the break-even move it shows?

It is the minimum price rise per share needed to cover all charges before you start making an actual profit. If your target price gain is smaller than this figure, the trade will lose money even if the stock price technically moves in your favour.

Does stamp duty apply on both buy and sell?

No, stamp duty in Indian equity markets is charged only on the buy-side transaction value, at rates set by the state of the trading account holder, currently standardised at 0.015% for delivery and 0.003% for intraday trades nationally.
