Brokerage & Transaction Charges Calculator

Estimate total trading costs — brokerage, STT, GST, and stamp duty — on a stock trade (India-style).

How it works

Beyond broker commission, Indian equity trades typically attract Securities Transaction Tax (STT) on the sell side, 18% GST on brokerage, and stamp duty on the buy side. This is a simplified illustrative model, not any specific broker's exact charge sheet.

Why the sticker brokerage rate is never the whole story

A brokerage's advertised commission or fee is only one layer of the real cost of executing a trade — exchange transaction charges, regulatory fees, and in applicable markets, transaction taxes (such as India's Securities Transaction Tax) stack on top of the headline brokerage rate, and every one of these charges typically applies on both the buy and the sell leg of a completed trade, not just once. For a frequent trader making many smaller trades, this combined charge structure can quietly consume a meaningful share of gross profit — a percentage-based fee structure that looks negligible on one large trade becomes proportionally far more expensive across many small, frequent trades, since the fixed or minimum-fee components don't shrink with trade size.

This is exactly why comparing brokers on headline commission rate alone is incomplete — the full cost stack (brokerage + exchange charges + regulatory fees + applicable taxes, on both legs of the trade) is what actually determines net profitability, and two brokers with identical advertised commission rates can have meaningfully different total costs once the rest of the fee stack is accounted for. For active or frequent traders specifically, total transaction cost as a percentage of typical trade size is a far more useful comparison metric than the advertised commission rate in isolation, since it's the number that actually determines how much of a winning trade's gross profit survives to become real, bankable profit.

Frequently asked questions

Is the advertised brokerage commission the total cost of a trade?

No — exchange transaction charges, regulatory fees, and applicable transaction taxes stack on top of the headline brokerage rate, and these typically apply on both the buy and sell side of a completed trade. The full cost stack is usually meaningfully higher than the advertised commission rate alone.

Why do transaction costs matter more for frequent traders than occasional investors?

Because charges apply on every single trade, and fixed or minimum-fee components don't shrink proportionally with smaller trade sizes. A cost structure that's negligible on one large trade can consume a much bigger share of profit across many smaller, frequent trades, making total cost awareness especially important for active traders.

How should I actually compare brokers if headline commission rates aren't enough?

Compare total transaction cost (brokerage plus exchange charges, regulatory fees, and applicable taxes, on both trade legs) as a percentage of a typical trade size you'd actually place — not just the advertised commission figure. This gives a realistic picture of how much of a trade's gross profit actually survives as net, bankable profit.

Do transaction charges apply differently to different asset classes (stocks, options, futures)?

Yes — fee structures, exchange charges, and applicable regulatory or transaction taxes often differ by asset class and even by specific exchange or contract type. It's worth checking the specific charge structure for the particular instrument being traded rather than assuming a single rate applies universally across a broker's entire product range.
