Quick answer

Stock trading in India isn't free — every trade pays brokerage, STT, exchange transaction charges, GST, SEBI fees, and stamp duty. The calculator computes all six for any equity, futures, or options trade so you know exactly what your net profit is, not just gross.

What is Brokerage?

Even with discount brokers offering ₹20 flat brokerage on intraday and zero on delivery, every trade still incurs five other charges that add up. STT (Securities Transaction Tax) and stamp duty go to the government. Exchange transaction charges go to NSE/BSE. SEBI fees fund the regulator. GST sits on top of brokerage, exchange, and SEBI charges.

For active intraday traders, these charges can swallow a meaningful percentage of profits. A ₹10,000 gross profit on a fast-moving trade might net ₹9,500 after charges. Knowing the math is essential for setting realistic profit targets.

The calculator uses the discount-broker rate card (Zerodha, Upstox, Groww, Angel One). Full-service brokers like ICICI Direct or HDFC Securities charge a percentage of trade value (0.3-0.5%), making their charges several times higher.

Six-component charge breakdown

Each component is a different rate, applied to different bases. Brokerage is flat ₹20/order on intraday and F&O. STT depends on trade type. Exchange and SEBI are turnover-based. GST is 18% of (brokerage + exchange + SEBI). Stamp duty is buy-side only.

Formula

Net P&L = (Sell − Buy) × Qty − Brokerage − STT − Exchange − SEBI − GST − Stamp Duty

STT: Securities Transaction Tax—0.1% delivery (both sides), 0.025% intraday (sell), 0.02% futures, 0.05% options on premium
Stamp Duty: State stamp duty—0.015% delivery, 0.003% intraday, 0.002% futures (buy side only)
Exchange: Exchange charges—~0.00345% equity, ~0.0503% options

Worked example

Trade typeIntraday equity

Buy price₹1,000

Sell price₹1,010

Quantity100

Gross P&L = ₹1,000

Brokerage = ₹40 (₹20 each side)

STT = 1,01,000 × 0.025% = ₹25.25

Exchange + SEBI + GST + Stamp ≈ ₹14

Total charges ≈ ₹79

➜ Net profit: ~₹921 (vs ₹1,000 gross)

How to use this calculator

Pick trade type, enter buy price, sell price, quantity. The calculator returns gross P&L, all charges, and net P&L.

Pick trade type
Intraday equity (MIS), delivery equity (CNC), equity futures, or equity options. Each has different charge rates.
Enter buy and sell prices
The actual prices at which you executed. Use the contract note for past trades or your planned levels for prospective trades.
Enter quantity
Total shares traded. Both buy and sell quantities should match (else you have an open position).
Read the breakdown
Net profit/loss is the headline. The charge table itemises every component — useful for comparing against your broker's contract note.

When this calculator is useful

Setting realistic intraday profit targets

On small price moves, charges can equal 30-40% of gross P&L. Know the break-even before placing the order.

Comparing brokers

Run the same trade through Zerodha-style discount rates vs full-service rates. The difference is dramatic for active traders.

Strategy backtesting

When testing a trading strategy on historical data, deduct charges per trade — without that, paper-profit strategies often turn unprofitable in real life.

Pre-trade checks

Especially for low-margin trades, calculate net profit before entering to make sure the move is worth it.

Common mistakes to avoid

Ignoring charges in profit calculations

Always compute net, not gross. Use this calculator before entering trades and verify with your broker's contract note after.

Using full-service broker for active trading

Full-service brokers charge 0.3-0.5% of turnover. For 50+ trades/month, switch to a discount broker — saves ₹50K-2L/year.

Forgetting GST and exchange charges

Many traders only count brokerage and STT. The other components add another 5-10% to total charges. Use the breakdown table to see the full picture.
