Brokerage and STT Calculator (NSE Equity and F&O)

Work out brokerage, STT, exchange fees, stamp duty and GST on an NSE equity or F&O trade, with your net profit and breakeven price.

What you pay on every trade

A share or derivatives trade in India carries two kinds of cost. Brokerage is set by your broker. The rest are statutory and exchange charges that every broker collects at the same rates and passes on. The calculator treats one buy order and one sell order as a round trip:

• Brokerage: either a flat fee per executed order, or a percentage of the order value with a cap per order (for example 0.03% or ₹20, whichever is lower). Many brokers charge nothing on delivery trades; set the fee to 0 if that applies to you.
• STT (securities transaction tax): a tax on the trade value, at rates set by the Finance Act. On delivery trades it is charged on both the buy and the sell; on intraday, futures and options it is charged on the sell side only.
• Exchange transaction charges: NSE’s fee per crore of turnover, which includes a small contribution to the NSE Investor Protection Fund Trust (IPFT).
• SEBI turnover fee: ₹10 per crore of turnover.
• Stamp duty: charged on the buyer only, at rates fixed under the Indian Stamp Act and collected by the exchange’s clearing corporation.
• GST: 18% on brokerage, exchange transaction charges and the SEBI fee. GST is not charged on STT or stamp duty.
• DP charge: on delivery sales only, your depository participant charges a fee per scrip per day when shares leave your demat account. It varies by broker (often about ₹10 to ₹20 plus GST), so the field is editable.

The formulas

With buy value B = buy price × quantity, sell value S = sell price × quantity and turnover T = B + S:

• STT = B × buy rate + S × sell rate
• Exchange charges = T × NSE rate
• SEBI fee = T × 0.0001%
• Stamp duty = B × stamp rate
• GST = 18% × (brokerage + exchange charges + SEBI fee)
• Net P&L = S − B − all charges

The breakeven sell price is the price at which net P&L is exactly zero. Because some charges grow with the sell price, the calculator finds it by trial (bisection) rather than simply adding charges ÷ quantity to the buy price. “Points to break even” shows total charges ÷ quantity as a quick guide.

Rates used

For options, every percentage applies to the premium (price × quantity), not to the contract’s notional value. The STT figures above are the rates from 1 April 2026, when the Finance Act, 2026 raised STT on futures from 0.02% to 0.05% and on options from 0.1% to 0.15% of the premium. Those rates had last been raised from 1 October 2024 by the Finance (No. 2) Act, 2024. Delivery and intraday STT did not change.

Worked example

A delivery trade: buy 100 shares at ₹1,500 and sell them later at ₹1,560, with flat brokerage of ₹20 per order and a DP charge of ₹13.50.

• B = ₹1,50,000, S = ₹1,56,000, T = ₹3,06,000. Gross profit = ₹6,000.
• Brokerage = 2 × ₹20 = ₹40.
• STT = 0.1% × ₹3,06,000 = ₹306.
• NSE charges = 0.00307% × ₹3,06,000 ≈ ₹9.39. SEBI fee ≈ ₹0.31.
• GST = 18% × (40 + 9.39 + 0.31) ≈ ₹8.95.
• Stamp duty = 0.015% × ₹1,50,000 = ₹22.50. DP charge = ₹13.50 + 18% GST = ₹15.93.
• Total charges ≈ ₹403.08, net profit ≈ ₹5,596.92, and the breakeven sell price is about ₹1,503.97.

An options trade with the same flat brokerage: buy 300 units at a premium of ₹120 and sell at ₹135. Here STT is 0.15% of the ₹40,500 sell premium (₹60.75) and total charges come to about ₹141.19, against a gross profit of ₹4,500.

Assumptions and limits

• Rates are for NSE. BSE’s transaction charges differ, and the SEBI fee, STT and stamp duty are the same on both exchanges.
• Brokers round some items on the contract note (STT, for example, is usually rounded per contract), so your note can differ by a few rupees.
• Options are assumed to be squared off before expiry. If an option is exercised, STT of 0.15% is charged on the settlement price (intrinsic value) and is paid by the buyer, which this calculator does not model.
• Not included: income tax on profits, interest on margin, call-and-trade or auto square-off fees, and charges on pledging.

Frequently asked questions

Is STT charged on both the buy and the sell side?

Only for delivery trades in shares, where 0.1% applies on each side. For intraday equity trades, futures and options, STT is charged on the sell side only.

Why are charges a larger share of the trade in options?

Options charges are worked out on the premium, which is small next to the contract’s size, while the flat brokerage stays the same. NSE’s transaction charge on options premium is also much higher in percentage terms than on cash trades.

Does intraday trading have a DP charge?

No. A DP charge applies when delivered shares are debited from your demat account. Intraday trades are squared off the same day, so no shares leave your demat account.

Where can I check the charges on my own trades?

Your broker’s contract note lists every item for each trading day. Compare it with this calculator to see how your broker’s brokerage and DP fees affect your costs.
