The short answer: what you’ll actually pay on an options trade
Here’s the headline number: buying and selling one NIFTY option lot (premium ₹100, one lot of 65 shares) costs roughly ₹63 in total charges — ₹26.49 on the buy leg and ₹36.04 on the sell leg. That’s about ₹0.96 per share just to get in and out. The option has to move in your favour by that much before you’ve made a single rupee of profit.
This article breaks down every charge line by line, shows the exact maths for both buying and selling an option, and explains why most traders underestimate what they’re really paying.
Charge figures verified as of September 2026. Broker fee schedules change — always confirm with your broker’s latest schedule before trading.
Why options traders underestimate their costs
Most traders look at one number: brokerage. A discount broker advertises “₹20 per order” (the Zerodha-style flat fee, verified September 2026 — the norm, though not universal; full-service brokers charge differently), and the trader files it away as “my cost is ₹20.”
That is the advertised-brokerage trap. On a typical options round trip, brokerage is the single biggest line item — but it’s only about 60% of the total bill. The rest comes from four charges the broker doesn’t set and can’t waive: Securities Transaction Tax (STT), exchange transaction charges, SEBI turnover fee, and stamp duty, plus GST on some of them. None of these show up in the broker’s marketing. All of them come out of your P&L.
The other trap is assuming these are negligible. On a small option premium they are not. Paying ₹62.53 on ₹13,000 of round-trip premium turnover is roughly 0.48% of the trade — paid in full whether you win or lose.
The six options trading charges, explained one by one
Every options trade in India carries some combination of these six charges. Here’s the full picture:
| # | Charge | Rate | Who pays | Which leg |
|---|---|---|---|---|
| 1 | Brokerage | Flat ~₹20 per executed order (discount-broker norm) | Both buyer and seller | Both legs |
| 2 | STT (Securities Transaction Tax) | 0.15% of premium on sale; 0.15% of intrinsic value on exercise | Seller (sale) / purchaser (exercise) | Sale leg only |
| 3 | Exchange transaction charges | NSE: ₹35.03 per lakh (0.03503%); BSE Sensex/Bankex: ₹3,250 per crore (Oct-2024 figure) | Both | Both legs |
| 4 | SEBI turnover fee | ₹10 per crore (0.0001%) | Both | Both legs |
| 5 | Stamp duty | 0.003% of premium turnover | Both | Buy side only |
| 6 | GST | 18% on (brokerage + exchange transaction charges) | Both | Both legs |
Two rules underpin everything: all charges are computed on premium turnover, never on notional value, and there are no DP (depository) charges in F&O — that’s an equity-delivery concept that doesn’t apply here.
Brokerage — the advertised number
Brokerage is what your broker charges per executed order. The discount-broker norm is a flat ₹20 per executed order (Zerodha, verified September 2026), so a round trip — buy and sell, two orders — costs ₹40 in brokerage. Full-service brokers may charge a percentage instead, and even discount brokers’ plans can vary by segment, so check your broker’s schedule rather than assuming ₹20.
STT — the one most traders get wrong
STT has two different treatments for options, and mixing them up is the most common costing mistake:
- On the sale of an option: 0.15% of the premium, paid by the seller. This rate is effective 1 April 2026 (it was 0.10% before). There is no STT on buying an option.
- On an exercised option: 0.15% of the intrinsic value, paid by the purchaser. If the option expires worthless, there is no exercise STT.
So STT follows whoever is selling premium or exercising — not whoever opens the trade. Keep this in mind — it’s what creates the buyer/writer asymmetry explained below.
Exchange transaction charges (NSE and BSE)
The exchanges charge a percentage of premium turnover on both the buy and sell sides:
- NSE: ₹35.03 per lakh of premium turnover — that’s 0.03503%.
- BSE (Sensex/Bankex options): ₹3,250 per crore of premium turnover — the last verified figure is from October 2024. A cut to this rate has been reported for 2026 but is unverified, so use the Oct-2024 figure and check the current BSE circular before trading.
SEBI turnover fee, stamp duty, and GST
- SEBI turnover fee: ₹10 per crore of premium turnover (0.0001%), on both sides. Tiny, but always there.
- Stamp duty: 0.003% of premium turnover, on the buy side only. This is the mirror image of STT: where STT hits the sale, stamp duty hits the purchase.
- GST: 18%, charged only on brokerage + exchange transaction charges. STT and stamp duty sit outside GST — you do not pay GST on either.
Option buyers vs option sellers: what differs and why
The charge schedule is identical for everyone — what differs is which side of each trade you’re on. Since STT applies to the sale leg and stamp duty applies to the buy leg, a round trip distributes the two charges differently depending on your role:
| Round trip | Entry leg | Exit leg |
|---|---|---|
| Buyer (buy first, sell later) | Stamp duty, no STT | STT, no stamp duty |
| Writer/seller (sell first, buy back later) | STT, no stamp duty | Stamp duty, no STT |
Brokerage, exchange transaction charges, and the SEBI fee apply to both legs for both roles. The asymmetry means a buyer’s cheapest leg is the entry and the seller’s cheapest leg is the exit — and it means you cannot reuse one “options cost” number for both roles. Now, the actual maths.
Worked example 1: buying a NIFTY option, rupee by rupee
Setup: You buy 1 lot of a NIFTY call option at a premium of ₹100 (NIFTY lot size: 65 shares, effective January 2026). Premium turnover per leg = 100 × 65 = ₹6,500. You sell it later at the same ₹100 premium, so this example shows pure cost — how much you must overcome just to break even.
Buy leg (entry)
| Charge | Calculation | Amount |
|---|---|---|
| Brokerage | Flat per order | ₹20.00 |
| NSE transaction charge | 0.03503% × ₹6,500 | ₹2.28 |
| SEBI turnover fee | 0.0001% × ₹6,500 | ₹0.01 |
| Stamp duty (buy side) | 0.003% × ₹6,500 | ₹0.20 |
| STT | None on purchase | ₹0.00 |
| GST | 18% × (₹20.00 + ₹2.28) | ₹4.01 |
| Buy leg total | ₹26.49 |
Sell leg (exit)
| Charge | Calculation | Amount |
|---|---|---|
| Brokerage | Flat per order | ₹20.00 |
| NSE transaction charge | 0.03503% × ₹6,500 | ₹2.28 |
| SEBI turnover fee | 0.0001% × ₹6,500 | ₹0.01 |
| Stamp duty | None on sale | ₹0.00 |
| STT on sale of option | 0.15% × ₹6,500 | ₹9.75 |
| GST | 18% × (₹20.00 + ₹2.28) | ₹4.01 |
| Sell leg total | ₹36.04 |
Round-trip total
| Amount | |
|---|---|
| Buy leg | ₹26.49 |
| Sell leg | ₹36.04 |
| Total cost of the round trip | ₹62.53 |
There it is: ₹62.53 — the headline figure from the top of this article. STT on the sale leg (₹9.75) is the single biggest non-brokerage charge. Spread across 65 shares, your cost is ₹62.53 ÷ 65 = ₹0.96 per share. The option must move at least ₹0.96 in your favour before you break even.
Figures rounded to paise; totals may differ by a paisa either way.
Worked example 2: selling an option, rupee by rupee
Setup: You sell (write) 1 lot of a NIFTY put at a premium of ₹150 (65 shares per lot). Premium turnover per leg = 150 × 65 = ₹9,750. You buy it back later at the same ₹150 to close. Notice how the STT and stamp-duty positions flip versus the buyer example.
Sell leg (entry for the writer)
| Charge | Calculation | Amount |
|---|---|---|
| Brokerage | Flat per order | ₹20.00 |
| NSE transaction charge | 0.03503% × ₹9,750 | ₹3.42 |
| SEBI turnover fee | 0.0001% × ₹9,750 | ₹0.01 |
| STT on sale of option | 0.15% × ₹9,750 | ₹14.63 |
| Stamp duty | None on sale | ₹0.00 |
| GST | 18% × (₹20.00 + ₹3.42) | ₹4.22 |
| Sell leg total | ₹42.26 |
Buy-back leg (exit for the writer)
| Charge | Calculation | Amount |
|---|---|---|
| Brokerage | Flat per order | ₹20.00 |
| NSE transaction charge | 0.03503% × ₹9,750 | ₹3.42 |
| SEBI turnover fee | 0.0001% × ₹9,750 | ₹0.01 |
| Stamp duty (buy side) | 0.003% × ₹9,750 | ₹0.29 |
| STT | None on purchase | ₹0.00 |
| GST | 18% × (₹20.00 + ₹3.42) | ₹4.22 |
| Buy-back leg total | ₹27.93 |
Round-trip total: ₹70.20
| Amount | |
|---|---|
| Sell leg | ₹42.26 |
| Buy-back leg | ₹27.93 |
| Total cost of the round trip | ₹70.20 |
That’s ₹70.20 ÷ 65 = ₹1.08 per share. The writer breaks even only if the buy-back premium is at least ₹1.08 below the sale premium (₹148.92 or lower against a ₹150 sale). Two lessons here: the writer pays STT up front on entry (₹14.63 — the biggest single non-brokerage charge in this trade), and because charges scale with premium, a higher-premium option costs more in absolute rupees than the ₹100 example — even though the structure is identical.
True breakeven: how costs change which trades are worth taking
Breakeven on an options trade is not the strike price, and it’s not the premium you paid. True breakeven is your entry premium plus (for a buyer) or minus (for a seller) the per-share cost of the round trip. Everything between gross P&L and net P&L is charges, and ignoring them means taking trades that can’t win.
From the two worked examples:
| Buyer (₹100 premium) | Writer (₹150 premium) | |
|---|---|---|
| Round-trip charges | ₹62.53 | ₹70.20 |
| Cost per share | ₹0.96 | ₹1.08 |
| Breakeven premium move | +₹0.96 (exit ≥ ₹100.96) | −₹1.08 (buy-back ≤ ₹148.92) |
Put it in profit terms: if the buyer sells the ₹100 option at ₹120, the gross profit is (120 − 100) × 65 = ₹1,300, but the net profit is ₹1,300 − ₹62.53 = ₹1,237.47. The smaller the move, the more that gap matters — a ₹0.50 favourable move shows a “profit” on the screen but is a loss after charges.
This is where an options breakeven calculator earns its keep: plug in the premium, lot size, and exchange before you trade, and it tells you the real number the trade has to beat. Anything that can’t clear that number isn’t a trade — it’s a donation.
Estimate charges before you trade — and re-check what changes
Costs are knowable before you enter — treat the estimate as part of the trade plan, not an afterthought:
- Estimate the round trip before entering. You know the premium, the lot size, and the exchange. That’s everything needed to compute all six charges. If your broker’s calculator is clunky, build the formula yourself — the rates in the table above are all you need.
- Know which exchange you’re trading on. NSE and BSE charge different transaction fees; the BSE Sensex/Bankex figure in this article is the Oct-2024 verified one, and a reported 2026 cut is unverified — check the current circular.
- Watch what you do near expiry. If an in-the-money option is exercised instead of squared off, STT applies at 0.15% of intrinsic value, paid by the purchaser. On a deep-ITM option, intrinsic-value STT can dwarf every other charge. Squaring off before expiry is usually cheaper — verify the maths for your position.
- Count the conditional costs. Auto square-off charges and call-and-trade fees (around ₹50 + GST per order) are not always-on costs, but if your broker squares you off or you phone in an order, they land on the bill. Add them to the estimate when they apply.
- Re-check rates periodically. SEBI and exchanges revise fee schedules; STT itself changed in April 2026. A calculation from last year’s rates is a guess, not an estimate.
Risks and limitations you must accept
Costs are only half the story. The other half is that most options traders lose money — a SEBI study found that roughly 9 out of 10 individual F&O traders lose money (figures covering approximately the three years to FY24; treat the headline carefully, but the direction is unambiguous). Understanding charges does not change those odds by itself.
What understanding charges does change is your trade selection: it stops you from taking trades that can’t win, and it forces honest P&L accounting. It does not guarantee profit, it does not make a strategy safe, and breakeven maths is not a trading signal.
Also note the framework limits: SEBI’s F&O framework sets minimum contract sizes in the ₹15–20 lakh range and one weekly expiry per exchange — options are leveraged instruments by construction, and leverage amplifies losses as readily as gains. This article is educational content, not financial advice, and nothing here should be read as a recommendation to trade.
Key takeaways: the risk-first mindset
- A typical one-lot NIFTY option round trip costs ~₹63 in charges (₹26.49 to buy, ₹36.04 to sell at ₹100 premium) — know this number before you trade, not after.
- Brokerage is the advertised cost; STT, exchange charges, SEBI fee, stamp duty, and GST make up the rest. The broker’s headline number is not your cost.
- STT hits the sale leg (0.15% of premium); stamp duty hits the buy leg (0.003%). Buyers and writers therefore pay different totals for the same premium.
- All charges are computed on premium turnover, never notional. There are no DP charges in F&O.
- True breakeven = entry premium ± per-share round-trip cost. A trade that can’t clear it is a loss by design.
- Around 9 in 10 individual F&O traders lose money (SEBI study, ~3 years to FY24). Estimate your costs, size for the worst case, and treat every trade as risk first.
