NSE transaction charges are fees the exchange levies on every trade: 0.03553% of premium on options and 0.00183% of contract value on futures.
NSE exchange transaction charges are fees the National Stock Exchange levies on every executed trade for running the trading platform and matching engine. Unlike brokerage, which your broker sets and keeps, this charge is set by NSE. Your broker collects it from you and passes it on to the exchange, and it shows up as its own line on your contract note.
NSE transaction charges = traded value × rate. For options, the traded value is the premium, not the contract size.
The charge applies to both the buy and the sell side of every trade, whether the trade made money or not.
You buy one lot of a Nifty call (65 units) at ₹120 and sell it at ₹150.
You buy one lot of Nifty futures at 22,776.10 and sell at the same price.
The futures rate is about 19 times lower than the options rate, but it applies to the full contract value instead of a small premium. That is why a futures round trip costs more in exchange charges than an options round trip.
You buy 100 shares at ₹1,000 and later sell them at ₹1,050.
Together with brokerage, STT, SEBI fees and stamp duty, transaction charges make up the gap between gross P&L vs net P&L. To see what a setup nets after charges before you take it, run the numbers through Stolo’s scalping calculator.
