Stock Profit Calculator

Calculate stock profit, loss and net returns after charges.

What is it?

A Stock Profit Calculator helps investors and traders work out the actual profit or loss from a stock transaction after accounting for estimated trading charges like brokerage, STT, exchange fees, and GST.

Formula

Gross Profit = (Sell Price − Buy Price) × Quantity

Net Profit = Gross Profit − Total Charges

Formula Explanation

Gross profit is the raw price difference multiplied by quantity — the number most people think of as "profit." But real trades incur several small charges: Securities Transaction Tax (STT), exchange transaction charges, SEBI charges, GST on those charges, and stamp duty. Delivery and intraday trades have different charge structures, most notably that intraday trades pay brokerage while typical delivery trades often don't.

Example Calculation

Buying 100 shares at $100 and selling at $120 (delivery trade) gives a gross profit of $2,000, but after roughly $24 in estimated charges, the net profit is about $1,976 — a 19.76% return.

How to Use

  1. Enter the buy price and sell price per share.
  2. Enter the quantity of shares traded.
  3. Select the trade type — Delivery or Intraday (charges differ between the two).
  4. View gross profit, estimated charges, and net profit after charges.

Benefits

  • Shows your realistic take-home profit, not just the headline price difference.
  • Distinguishes delivery and intraday charge structures, which differ meaningfully.
  • Useful for evaluating whether a trade was actually worthwhile after costs.

Use Cases

  • Checking the real profit or loss on a completed stock trade.
  • Comparing whether a delivery or intraday approach nets more after charges.
  • Understanding how much charges eat into small or short-term trades.

What Your Result Means

Net profit is your actual take-home gain (or loss) after all estimated charges are subtracted from the gross profit. Charges matter proportionally more on smaller trades, so the return percentage can differ noticeably from a naive gross-profit calculation.

Tips

  • Charges eat into small trades proportionally more than large ones — factor this in for frequent small trades.
  • Intraday trades typically incur brokerage that delivery trades often don't, changing the charge structure meaningfully.
  • Always check your actual broker's fee schedule, since exact charges vary by broker and plan.

Common Mistakes

  • Judging trade profitability by gross profit alone, ignoring charges entirely.
  • Assuming delivery and intraday trades have identical charge structures — they don't.
  • Not accounting for capital gains tax separately from these transaction charges.

FAQs

Does this include trading charges?

Yes, estimated brokerage, STT (Securities Transaction Tax), GST, exchange charges, and stamp duty are all factored into the net profit.

Can I calculate intraday profit?

Yes, select Intraday as the trade type — charges differ from delivery trades since intraday attracts brokerage and different STT rates.

Can I calculate delivery profit?

Yes, select Delivery to estimate returns for trades where you hold the shares beyond the trading day.

Are these charge estimates exact?

No, they are reasonable approximations based on common Indian equity market charge structures — your actual broker may charge slightly different rates.

Does this include capital gains tax?

No, this calculator estimates transaction charges only, not capital gains tax, which depends on your holding period and applicable tax rules.

Charge estimates are approximate and may vary by broker. This calculator provides estimates for informational purposes only.
