How is brokerage calculated in stock trading?

It comes down to which pricing plan is linked to your account. Under a flat-fee model, the broker charges a fixed amount per executed order, say ₹20, whether you trade 10 shares or 1,000. Under a percentage model, brokerage is calculated as a percentage of turnover, often with a minimum and maximum cap per order, so a ₹1 lakh trade at 0.03% works out to ₹30, but a ₹2,000 trade at the same rate might hit the minimum floor instead. Segment matters too: equity delivery, equity intraday, and F&O usually sit on separate rate cards, and options brokerage is frequently a flat fee per lot rather than a percentage. You calculate the expected brokerage before placing a large order using the broker’s calculator, then cross-check it against the contract note once the trade settles.
