How to Use This Calculator
Delivery Trade tab
Enter your buy price, sell price, and quantity of shares. Select your broker (Zerodha, Angel One, Groww, or a traditional broker charging 0.3%). The calculator instantly shows all charges: brokerage, STT, transaction charges, GST, SEBI turnover fees, stamp duty, and DP charges. It also calculates your net profit after all charges and the breakeven sell price you need to cover costs.
Intraday Trade tab
Same inputs, but with intraday-specific rates: lower STT (0.025% sell side vs 0.1% delivery), lower stamp duty (0.003% vs 0.015%), and no DP charges. The calculator also shows how much you save compared to delivery for the same trade, helping you understand the cost advantage of intraday trading.
F&O Charges tab
Choose between Options or Futures, enter the premium/price, lot size, and number of contracts. For options, the calculator uses the post-Budget 2026 STT rate of 0.15% and shows the critical warning about ITM expiry. For futures, it uses 0.05% STT and lower transaction charges. It shows the points you need to recover to cover your trading costs.

How Stock Trading Charges Are Calculated
Every stock trade in India involves 6 types of charges beyond brokerage. These are regulatory and statutory charges that apply regardless of your broker:
1. Brokerage — Zerodha/Angel One: &rupee;0 delivery. Traditional: 0.3% both sides.
2. STT = 0.1% × (Buy Value + Sell Value) — split equally between buy and sell
3. Transaction Charges = 0.00345% × Turnover (NSE rate)
4. GST = 18% × (Brokerage + Transaction Charges)
5. SEBI Charges = 0.0001% × Turnover (&rupee;10 per crore)
6. Stamp Duty = 0.015% × Buy Value (buy side only)
7. DP Charges = &rupee;15.93 per scrip on sell (CDSL, delivery only)
Net P&L = (Sell Value − Buy Value) − Total Charges
For Intraday: STT = 0.025% sell side only. Stamp Duty = 0.003%. No DP charges.
For F&O Options: STT = 0.15% sell side (Budget 2026). Transaction = 0.0495%. Stamp = 0.003%.
For F&O Futures: STT = 0.05% sell side (Budget 2026). Transaction = 0.00180%. Stamp = 0.002%.
STT (Securities Transaction Tax) is typically the largest regulatory cost for delivery trades. For a &rupee;1 lakh delivery trade, STT alone is &rupee;100 (0.1%). On discount brokers with zero brokerage, STT often accounts for 60-70% of total trading costs.
Example
Priya buys 100 shares of Infosys at &rupee;1,500 and sells at &rupee;1,600 on Zerodha
Priya is a retail investor using Zerodha (zero delivery brokerage). She buys 100 shares of Infosys at &rupee;1,500 and sells them a month later at &rupee;1,600. Let us calculate her actual profit after all charges.
Step 1: Trade values
Step 2: All charges
Step 3: Net profit
Priya's charges are just &rupee;361 on a &rupee;3.1 lakh trade, thanks to Zerodha's zero delivery brokerage. On a traditional broker at 0.3%, brokerage alone would be &rupee;930, making total charges over &rupee;1,300. STT (&rupee;310) is by far the largest cost — it is a government tax and cannot be avoided.
