NSE Exchange Transaction Charges

NSE exchange transaction charges are fees levied by the National Stock Exchange itself for providing the trading infrastructure and matching engine that executes every order. Unlike brokerage, which the broker sets and keeps, this charge is set by the exchange and passed through to the trader via the broker, appearing as a distinct line item on the contract note for every F&O trade. It applies separately to the equity, futures, and options segments, and the rate structure differs across segments since options premiums and futures contract values are priced very differently.

Because this charge is levied on every executed trade regardless of outcome, it behaves like STT and SEBI regulatory fees in that it is unavoidable friction baked into simply participating in the market, a trader pays it on both the entry and the exit of a position, and it is charged whether the trade made money or lost money. For a trader running frequent intraday option trades around Nifty or Bank Nifty weekly expiries, this per-trade charge compounds across dozens of executions a week in a way that is easy to overlook if only the price movement of each trade is tracked.

Exchange transaction charges are typically calculated as a small percentage of the total turnover (premium value traded) for options, and of contract value for futures. Because rates are revised periodically by NSE notification, traders should not anchor to a specific number from memory, the mechanism (a turnover-based fee charged by the exchange on every trade) is what stays constant, not the rate.

This charge, along with GST on brokerage and the other statutory levies, is exactly what makes a trade’s gross P&L vs net P&L diverge, a strategy that appears to break even on raw premium movement can still post a net loss once exchange charges are subtracted from every leg.
