Brokerage Calculator — Know Your Real Trading Costs Before Every Trade

Every trade on NSE or BSE involves far more than just the broker's commission. Securities Transaction Tax, exchange transaction charges, SEBI regulatory fees, GST on services, and stamp duty all stack up — and for frequent intraday or F&O traders, these costs can easily exceed the brokerage itself. This calculator computes every charge accurately so you know your true net P&L before you hit the buy or sell button.

How to use this calculator

Select your trading segment — equity delivery, intraday, futures, or options — then enter the buy price, sell price, and quantity. The calculator instantly shows the gross P&L, itemised charges (brokerage, STT, exchange charges, SEBI levy, GST, and stamp duty), total charges, and net P&L after all deductions. For options, enter the premium instead of the stock price. Choose "Discount broker" (the default, based on Zerodha's published charges: ₹0 on delivery, lower of 0.03% or ₹20 per order on intraday and futures, ₹20 flat per order on options) or "Full-service" to apply your own brokerage percentage per side. The delivery result also includes the flat DP charge of ₹15.34 per scrip that applies when you sell.

Worked example: equity delivery on a discount broker

Buy 100 shares at ₹500 and sell at ₹520 (turnover ₹1,02,000). Brokerage ₹0, STT ₹102.00 (0.1% on buy and sell), NSE exchange charges ₹3.13, SEBI fee ₹0.10, GST ₹0.58, stamp duty ₹7.50 (0.015% of the ₹50,000 buy value) and DP charge ₹15.34. Total charges are about ₹128.66, so a gross profit of ₹2,000 becomes a net profit of about ₹1,871.34.

Understanding STT and other statutory charges

Securities Transaction Tax (STT), introduced under Chapter VII of the Finance (No. 2) Act, 2004, is the largest statutory cost for most traders. For equity delivery, STT is 0.1% on both buy and sell sides. For intraday, it drops to 0.025% on the sell side only. F&O traders pay STT only on the sell side: since 1 April 2026 (Finance Act 2026) that is 0.05% for futures and 0.15% of the premium for options, up from 0.02% and 0.10%. SEBI charges ₹10 per crore of turnover, while exchange transaction charges differ between NSE and BSE (this calculator uses NSE rates, which include the exchange's investor protection fund contribution). Stamp duty is charged only on the buy side at uniform national rates: 0.015% for delivery, 0.003% for intraday, 0.002% for futures and 0.003% of premium for options.

Who uses this tool

Retail equity investors use it to verify whether a short-term trade is worth the round-trip cost before execution. Intraday traders use it to calculate breakeven points — the minimum price movement needed just to cover all charges. F&O traders use it to compare the cost difference between buying options versus selling them, since STT treatment differs significantly. Beginners use it to understand why their realized P&L on the broker's statement is lower than expected.
