Stock Profit Calculator
Calculate stock profit, loss and net returns after charges.
What Is the Stock Profit Calculator?
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. The headline price difference between what you paid and what you sold for — the "gross profit" — is rarely what actually lands in your account.
Every trade on an Indian stock exchange picks up several small charges along the way: Securities Transaction Tax, exchange transaction charges, SEBI turnover charges, GST on some of those charges, and stamp duty, plus brokerage on intraday trades. Individually each charge looks tiny, but together they can meaningfully eat into the profit on a small or short-term trade, which is exactly the kind of gap this calculator is built to surface.
If you built your position gradually across several purchases rather than one buy order, work out your true average cost basis first with the Stock Average Calculator, then use that average as the buy price here for an accurate profit calculation.
Stock Profit Calculator Formula
Gross Profit = (Sell Price − Buy Price) × Quantity
Net Profit = Gross Profit − Total Charges
How Is the Stock Profit Calculator Calculated?
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.
STT in particular is charged differently depending on trade type: delivery trades attract STT on both the buy and sell side, while typical intraday trades attract it only on the sell side, but usually at a different rate. These structural differences mean the same gross profit can translate into a noticeably different net profit depending purely on which trade type you select, which is why this calculator asks for it explicitly rather than applying one flat charge estimate to every trade.
Stock Profit Calculator Example
Example 1 (delivery, profit): Buying 100 shares at $100 and selling at $120 (delivery trade) gives a gross profit of $2,000, but after about $24 in estimated charges, the net profit is about $1,976 — a 19.76% return.
Example 2 (intraday, smaller margin): Buying 200 shares at $100 and selling the same day at $105 gives a gross profit of $1,000, but intraday brokerage and charges of about $55 bring the net profit down to about $945 — a 4.73% return, illustrating how charges eat up a much bigger share of a thinner margin.
Example 3 (delivery, loss): Buying 50 shares at $500 and selling at $480 gives a gross loss of $1,000, and after about $55 in charges, the net loss widens slightly to about $1,055 — a reminder that charges apply on losing trades too, not just winning ones.
How to Use the Stock Profit Calculator
Step 1
Enter the buy price and sell price per share.
Step 2
Enter the quantity of shares traded.
Step 3
Select the trade type — Delivery or Intraday (charges differ between the two).
Step 4
Click Calculate Profit to view gross profit, estimated charges, and net profit after charges.
Step 5
Check the return percentage to compare this trade's efficiency against others regardless of trade size.
Step 6
Re-run the calculation with your actual broker's fee schedule in mind if it differs meaningfully from these estimates.
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.
- Makes the true cost of frequent small trades visible, which is easy to underestimate.
- Breaks charges out explicitly so you can see exactly how much they reduced your gross profit.
- Helps set realistic profit-taking targets that already account for round-trip trading costs.
Common Stock Profit Calculator Scenarios
Scenario 1
Checking the real profit or loss on a completed stock trade.
Scenario 2
Comparing whether a delivery or intraday approach nets more after charges.
Scenario 3
Understanding how much charges eat into small or short-term trades.
Scenario 4
Deciding whether a thin-margin intraday trade is even worth placing after estimated costs.
Scenario 5
Reviewing a trading journal to see true, charge-adjusted performance rather than headline gross figures.
Scenario 6
Estimating whether frequent small trades are quietly eroding your overall returns through repeated charges.
Understanding Your Result
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.
The return percentage is calculated on your buy value (investment), not on the profit itself, so it's directly comparable across trades of very different sizes — a 4.73% return on a small trade and a 4.73% return on a much larger one represent the same relative efficiency, even though the absolute rupee profit differs substantially.
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.
- Compare the return percentage, not just the rupee profit, when deciding which of several trades performed best.
- Remember charges apply whether the trade wins or loses — factor them into your stop-loss and target planning too.
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.
- Underestimating how much charges compound across many small, frequent trades over time.
- Comparing rupee profit across trades of very different sizes instead of comparing return percentage.
Frequently Asked Questions
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.
What's the difference between intraday and delivery trading charges?
Intraday trades (bought and sold the same day) typically have lower brokerage but different tax treatment, while delivery trades usually have higher charges like STT but may qualify for different capital gains tax rates — enter the trade type that matches your actual transaction.
Does this calculator account for capital gains tax?
No — it calculates net profit after estimated trading charges only; capital gains tax would further reduce your actual take-home profit depending on your holding period and jurisdiction.
Are the charge estimates the same across all brokers?
No — brokerage rates, STT, and other fees vary by broker and plan; treat this calculator's estimates as approximate and check your specific broker's actual fee schedule for precise figures.
What is STT?
Securities Transaction Tax — a tax levied on the value of securities transactions on Indian stock exchanges, charged automatically on both buy and sell sides for delivery trades.
Can I share my stock trade result as an image?
Yes — tap Share and, on supported devices, your net profit is shared as a branded image card, not just a text link.
Why does the same rupee amount of charges make a bigger dent in the intraday example than the delivery example?
Because intraday trades in this calculator include brokerage, which delivery trades typically don't, and intraday margins tend to be thinner in the first place — so a similar or even smaller absolute charge amount represents a much larger share of a smaller gross profit.
Do charges apply if I sell at a loss?
Yes — transaction charges like STT, exchange fees, and stamp duty are charged based on the value of the trade, not on whether it was profitable, so a losing trade's net loss is typically slightly worse than its gross loss once charges are included.
Why is my broker's actual charge breakdown slightly different from this calculator's estimate?
Brokerage plans, STT rates, and other charges can vary by broker, account type, and the specific exchange (NSE or BSE) — this calculator uses commonly cited approximate rates, so treat it as a close estimate rather than an exact reconciliation of your contract note.
Should I use this calculator before or after placing a trade?
Both are useful — before a trade, it helps you judge whether a thin expected margin is even worth the charges; after a trade, it helps you understand your true realized profit or loss beyond the headline price difference.
