What your trading charges actually include
Illustrative anatomy of an options trade cost. Exact figures depend on your broker and turnover; the calculator above sums them live.
The total is six charges, not one
Traders think of “brokerage” as the cost of a trade, but brokerage is often the smallest slice. Six separate charges make up what actually leaves your account:
- Brokerage: your broker’s own fee per executed order. Discount brokers charge a flat amount (often ₹15 to ₹20) or a small per-lot fee.
- STT (Securities Transaction Tax): a government tax charged on the sell side of options on the premium, and on both sides for delivery equity.
- Exchange transaction charges: a small percentage of turnover set by the exchange.
- GST: 18% charged on brokerage plus exchange charges, not on the whole trade.
- SEBI turnover fee: a tiny regulator levy on turnover.
- Stamp duty: a state charge on the buy side.
How they stack up
On a typical options trade through a discount broker, the split looks roughly like this. Notice how little of it is the brokerage itself.
Because STT and exchange charges are percentages of turnover, your cost rises with trade size even when a flat brokerage stays the same.
Why your broker’s bill can differ
- Plan: a flat ₹15 plan and a percentage plan produce very different totals at different trade sizes.
- Segment: options, futures, intraday equity and delivery each carry different STT and exchange rates.
- Extras this tool does not model: demat (DP) charges on delivery sells, call-and-trade fees, auto square-off charges and payment-gateway fees can all appear on a real contract note.
- Rounding: brokers round GST and other charges slightly differently.
Mistakes people make
- Assuming zero brokerage means zero cost. Even with free brokerage, STT, exchange charges, GST and stamp duty remain, and on options they are the bulk.
- Forgetting STT is on the sell side. For options it is charged on the premium when you sell, which quietly raises the cost of exiting.
- Ignoring the breakeven impact on small trades. On a one-lot trade, charges can be a real fraction of a modest profit, so the move has to cover them first.
- Overlooking DP charges. Delivery sells attract a per-scrip demat charge regardless of brokerage, which surprises new investors.
