The charge stack: what a trade costs after brokerage, and why the headline number misleads
The advertised brokerage figure is the one item on a contract note that does not move with the size of the trade. Everything else does — and each charge is levied on a different base, on a different side of the trade, and in some cases only in one segment. Knowing which is which is what lets you read a contract note instead of trusting a summary line.
What you will take away
- Brokerage is flat per order; the statutory charges are proportional — so cost as a share of turnover falls as the ticket grows and never reaches zero.
- GST is not 18% of your total cost. It applies to a defined subset of the charges, and STT and stamp duty sit outside it.
- Intraday and delivery are charged on different bases, not just at different percentages.
- Every charge on an index option is levied on the premium, never on the contract's notional value.
The only flat number is the advertised one
Brokerage is charged per order. The calculator on this site defaults to ₹20 per order — a typical discount-broker flat fee, and editable, because it is the one figure on this list that a broker sets rather than a statute. Being flat is what makes it quotable: it is the same number in an advertisement whether the trade is ₹5,000 or ₹5 lakh.
That is also what makes it a poor guide to cost. Because the flat fee does not scale and almost everything else does, total cost expressed as a percentage of turnover starts high on a small ticket, falls as the ticket grows, and then flattens onto a floor set by the statutory items. Two people quoting the same brokerage plan can be paying very different effective rates.
The headline figure describes the part of the bill that stops mattering as the trade gets larger. The part that keeps mattering is never in the headline.
The stack, charge by charge
Here is the cash-equity delivery stack as this site stores it, resolved for 2026-09-04. Each row carries its own effective date and source document, which is why a rate change here is a data edit rather than a rewrite of this paragraph.
| Charge | Which side pays | How it is levied | Inside the GST base? |
|---|---|---|---|
| Securities Transaction Tax (STT) | Both sides | 0.1% of turnover | No |
| Stamp duty | Buy side only | 0.015% of buy value | No |
| Exchange transaction charge | Both sides | ₹306.99 per crore of turnover | Yes |
| Investor Protection Fund (IPFT) | Both sides | ₹0.01 per crore of turnover | Yes |
| SEBI turnover fee | Both sides | ₹10 per crore of turnover | Yes |
| GST (18%) | Both sides | 18% of brokerage + exchange transaction charge + IPFT + SEBI turnover fee | It is the GST |
Notice the third column. Some charges are a percentage of a value and some are a rupee amount per crore of it, and the exchange quotes them that way. Converting a per-crore figure into a percentage in your head is where most spreadsheet versions of this table go wrong.
GST does not apply to everything
This is the most commonly mis-stated item in the stack. GST at 18% applies to a defined base: brokerage, Exchange transaction charge, Investor Protection Fund (IPFT), SEBI turnover fee. It does not apply to Securities Transaction Tax (STT) or Stamp duty.
So GST is not 18% of what a trade cost. It is 18% of a subset, and on a delivery trade that subset is usually far smaller than the tax items sitting outside it. Anyone who tells you to add 18% to your total charges is overstating the bill.
Intraday and delivery are not the same trade
The same stock, bought and sold on the same day, costs a different amount depending on the product selected in the order window. That selection is a decision made by the person placing the order, not something the market does to them.
| Charge | Intraday | Delivery |
|---|---|---|
| Securities Transaction Tax (STT) | 0.025% of sell value | 0.1% of turnover |
| Stamp duty | 0.003% of buy value | 0.015% of buy value |
Two things move at once here: the rate, and the base it is applied to. A charge on turnover touches both legs of the round trip; a charge on the sell value touches one. Comparing the percentages alone gives the wrong ranking.
What a rate table still cannot tell you
A table of rates does not answer the question people actually have, which is: how far does this have to move before the round trip is level? That is one number, in the unit already on the screen — a share price, or index points — and it is what the calculators produce from the same rate rows shown above.
- The trade cost calculator turns the cash-equity stack into a total and a level-money sell price for your own quantity and prices.
- The options breakeven calculator does the same for an index option, and reports the textbook breakeven and the breakeven once the whole stack is paid — the gap between the two is the part most tables never show.
Charges do not change what a market does. They change where the level-money line sits, and that line is a fact about your own trade that can be calculated before it is placed.
Limits, honestly stated
- Brokerage varies by broker and plan; the flat default here is an assumption to replace with your own.
- Depository participant charges on a delivery sale are levied by the depository participant, vary between them, and are not in this table.
- Statutory and exchange rates change by circular. Each row carries its effective date; if you are reading this long after the dates shown, re-check before relying on it.
- This is arithmetic on published rates, not tax advice. Your own tax position is not a charge on a contract note.

Is GST charged on STT?
No. GST applies to brokerage, Exchange transaction charge, Investor Protection Fund (IPFT), SEBI turnover fee. STT and stamp duty sit outside the GST base.
Why is the cost percentage higher on a small trade?
Because brokerage is charged per order regardless of size. On a small ticket that flat fee is a large share of the total; on a larger one it is a small share, so the effective percentage falls toward the statutory floor.
Are option charges based on the strike?
No. Every charge shown here is levied on the premium — premium multiplied by quantity — not on the strike multiplied by quantity. The two differ by the ratio of strike to premium.
Does this tell me whether a trade is worth making?
No. NiftyScanner publishes arithmetic and the sources behind it. It does not assess trades, give advice, or say what anyone should do.
