What Intraday Profit and Loss Really Looks Like
Intraday trading, buying and selling the same stock within a single trading session, promises quick profits, and the numbers on your screen during a good day can look thrilling. But the profit you see before charges is not the profit you keep, and the percentage return you brag about is often measured against the wrong base. To trade intraday sensibly, you need to see your net profit or loss after every charge, and to understand your return on the margin you actually put up rather than on the full value of the position, because leverage makes those two numbers very different.
Your gross profit or loss is simple: for a long trade, it is the exit price minus the entry price, times the quantity; for a short trade, where you sell first and buy back later, it is the entry price minus the exit price, times the quantity. But from that gross figure, a stack of charges is deducted: brokerage, the Securities Transaction Tax, exchange transaction charges, GST, the SEBI fee, and stamp duty. Together these are small in percentage terms but they matter, especially on frequent trading and on small moves, because they set a breakeven the stock must clear before you make a single rupee. This calculator computes all of them for your trade and shows your true net result.
The bigger revelation for most traders is leverage. Intraday brokers let you take a position far larger than your capital by putting up only a fraction as margin. Under the current rules, this is capped at around five times for liquid stocks. So with one lakh of margin, you can hold a five lakh position. If the stock moves 2 per cent in your favour, you make about ten thousand, which is 2 per cent of the five lakh position but a striking 10 per cent of your one lakh margin. That amplification, five times the percentage return, is exactly why intraday trading with leverage is so seductive.
What that seductive maths hides is that the amplification is perfectly symmetric. The same five times multiplier applies to your losses. A 2 per cent move against you does not cost you 2 per cent, it costs you 10 per cent of your margin. And a move of just 20 per cent against a five times position, or correspondingly less for higher leverage, would wipe out your entire margin. This calculator shows you both edges of the sword together: your return on margin if the trade wins, and the loss on margin if the same-sized move goes against you, so you never see the upside of leverage without its matching downside.
Leverage, Margin, and Why the Base You Measure Against Matters
The single most important idea in leveraged intraday trading is that leverage does not change your rupee profit or loss at all. If your five lakh position gains ten thousand, it gains ten thousand whether you funded it fully or with one lakh of margin at five times leverage. What leverage changes is the percentage return on the capital you actually risked. Funded fully, ten thousand on five lakh is a 2 per cent return. Funded with one lakh of margin, the same ten thousand is a 10 per cent return on your margin. The profit is identical; the return depends entirely on which base you measure it against.
This is why measuring your return on margin, rather than on the full position value, is both the honest way to judge a leveraged trade and the reason leverage is dangerous. On the upside, it flatters your returns: a run of modest price moves can look like spectacular percentage gains on your small margin. On the downside, it is brutal: the same small adverse moves become large percentage losses on that margin, and because your margin is a fraction of the position, it takes only a modest move against you to erase it entirely.
A five times position wiped out by a 20 per cent move sounds far off, but with charges and the way losses compound across trades, real damage happens well before that. This calculator always shows your return on margin alongside your return on the position, so you see the leverage effect explicitly.
Charges deserve special attention in intraday because they are levied on the full position value, not on your margin. On a five lakh leveraged position, the STT, brokerage, exchange charges and the rest are computed on the five lakh, even though you only put up one lakh, so relative to your capital the charge burden is effectively multiplied by the leverage too. The good news is that intraday charges are lower than delivery: the Securities Transaction Tax is just 0.025 per cent and only on the sell side, a quarter of the delivery rate, and there is no DP charge because no shares are delivered to your demat. The bad news is that they still set a breakeven the stock must clear, and on a leveraged position that breakeven, measured against your margin, is meaningfully higher.
One more thing intraday traders must not forget is tax. Profit from intraday equity trading is not a capital gain; it is treated as speculative business income under Section 43(5) of the Income Tax Act, and taxed at your normal income tax slab rate, which for a higher earner can be 30 per cent plus cess. This also means you must file ITR-3, and that speculative losses can only be set off against speculative gains, not against your salary or other income, though they can be carried forward for four years. So the net profit this calculator shows is before that slab-rate tax, which will reduce your take-home further. Combine leverage, charges and slab-rate tax, and the honest picture of intraday trading is far more demanding than the thrilling screen numbers suggest.
How the Calculation Works
The tool computes your levered intraday result in four steps.
Step one: gross P&L
It computes your gross profit or loss from the entry and exit prices and quantity, correctly for the direction: a long trade profits when the price rises, a short trade profits when the price falls. This is your result before any charges.
Step two: the charge stack
It applies the full intraday charge stack on the position value: brokerage per your broker, the 0.025 per cent STT on the sell side, exchange transaction charges, GST on the brokerage and exchange charges, the SEBI fee, and stamp duty on the buy side. There is no DP charge for intraday. It subtracts these from your gross to give your net profit or loss.
Step three: margin and return on margin
It computes the full position value and, from your leverage, the margin you actually put up, position value divided by leverage. It then expresses your net result as a percentage of that margin, which is your true return on the capital you risked, and separately as a percentage of the full position, so you can see exactly how much leverage amplified the return.
Step four: the symmetric downside and breakeven
Finally it shows the other edge of the sword: what a move of the same size against you would have done to your margin, so the downside of leverage is always visible next to the upside. It also computes the breakeven, the price move needed just to cover charges, so you know how far the stock had to travel before you earned anything at all.
Three Worked Examples From Real Traders
Here are three intraday traders seeing the real, levered picture.
Karan sees the double edge in Mumbai
Karan, in Mumbai, went long 100 shares at five hundred rupees using five times leverage, putting up ten thousand of margin on a fifty thousand position, and closed at five hundred and ten, a 2 per cent move. On the tool, his net profit after charges came to a little under a thousand rupees, which was a modest 2 per cent on the position but a thrilling 10 per cent on his ten thousand margin.
Then the tool showed him the other edge: had the stock instead fallen 2 per cent, he would have lost about the same 10 per cent of his margin. Karan understood for the first time that his exciting 10 per cent gains and his frightening 10 per cent losses were the same coin, and he resolved to size his positions and set his stop-losses with that symmetry firmly in mind.
Meera shorts a falling stock in Bengaluru
Meera, in Bengaluru, expected a stock to fall, so she took a short position, selling 200 shares at eight hundred rupees intraday, and bought them back at seven hundred and ninety when the price dropped. On the tool, entering the trade as a short, she saw her gross profit of two thousand from the ten rupee fall, her charges, and her net profit, correctly computed for a short where profit comes from a falling price. The tool also reminded her that her intraday profit, long or short, is speculative business income taxed at her slab rate, not a capital gain, so she would need to file ITR-3 and could not offset a speculative loss against her salary. Meera had been unaware of the speculative-income treatment and was glad to learn it before filing season.
Arjun learns the breakeven lesson in Pune
Arjun, in Pune, liked to scalp tiny moves, entering and exiting for gains of a fraction of a per cent, many times a day. On the tool, he saw that his breakeven, the move needed just to cover charges, was a real hurdle: on his small, frequent trades the charges consumed much of the tiny moves he was capturing, and on his leveraged positions those charges, levied on the full position, were a larger bite relative to his margin than he had realised. Combined with the slab-rate tax on any profit and the fact that most of his trades barely cleared breakeven, Arjun concluded that his high-frequency scalping was enriching mainly the exchange and the taxman. He shifted to fewer, higher-conviction trades with clearer targets, and his net results improved.
Frequently Asked Questions on Intraday P&L
How do I calculate intraday profit or loss?
Your intraday profit or loss is your gross result from the trade, minus all the charges. The gross result depends on your direction: for a long trade, where you buy first and sell later, it is the exit price minus the entry price, multiplied by the quantity; for a short trade, where you sell first and buy back later, it is the entry price minus the exit price, times the quantity, so a short profits when the price falls. From this gross figure you subtract the charges: brokerage, the Securities Transaction Tax, exchange transaction charges, GST, the SEBI fee, and stamp duty, which together set a small but real cost. What remains is your net profit or loss. If you traded with leverage, you should then express that net result as a percentage of the margin you actually put up, not the full position value, to see your true return on the capital you risked. This calculator does all of this: it computes your gross P&L for long or short, subtracts the full charge stack, and shows your net result both in rupees and as a return on your margin and on the position, so you see the honest, complete picture rather than just the price difference.
What is return on margin, and why does it matter?
Return on margin is your net profit or loss expressed as a percentage of the margin you actually put up, rather than of the full value of the position you controlled. It matters because it is the true measure of how well the capital you risked performed. When you trade with leverage, you control a large position with a small margin, so a given rupee profit is a small percentage of the big position but a much larger percentage of your small margin. For example, a ten thousand rupee profit on a five lakh position is only 2 per cent of the position, but if you funded that position with one lakh of margin at five times leverage, it is a 10 per cent return on your margin. That 10 per cent is what your capital actually earned, and it is the number you should judge the trade by. The same logic applies, painfully, to losses: a small percentage move against a leveraged position is a large percentage loss on your margin. This calculator shows your return on margin prominently, alongside the return on the full position, precisely because return on margin is the honest measure of a leveraged trade, capturing both the amplified reward and the amplified risk that leverage brings.
How does leverage affect my intraday trade?
Leverage lets you take a position larger than your capital by putting up only a fraction of the value as margin. Under the current SEBI peak-margin rules, intraday equity leverage is capped at around five times for liquid stocks, so with one lakh of margin you can hold a five lakh position. The crucial thing to understand is that leverage does not change your rupee profit or loss; it changes the percentage return on the capital you risked. If your five lakh position gains ten thousand, that ten thousand is the same whether you funded it fully or with one lakh of margin, but as a return it is 2 per cent of the full position and 10 per cent of your one lakh margin. Leverage has multiplied your percentage return by five. This is why leverage is so attractive: it turns modest price moves into large percentage gains on your margin. But it is perfectly symmetric, so the same five times multiplier applies to losses, and a move of just 20 per cent against a five times position, or less for higher leverage, would wipe out your entire margin. This calculator shows both the amplified upside and the amplified downside, so you never see leverage’s reward without its matching risk.
Can leverage wipe out my capital?
Yes, and understanding how is essential before you trade with leverage. Because leverage means your margin is only a fraction of the position, it takes only a proportionally small move against you to erase that margin entirely. With five times leverage, your margin is 20 per cent of the position, so a 20 per cent adverse move in the stock wipes out 100 per cent of your margin. With higher leverage, an even smaller move does it. In practice, damage happens well before a full wipe-out, because charges add to your losses and because a string of leveraged losing trades compounds quickly, eroding your capital faster than unlevered trading would. This is the core danger of leverage: it magnifies losses just as much as gains, and a few bad trades on high leverage can do lasting harm to your account. It is why disciplined intraday traders use strict stop-losses to cap the loss on any single trade, size their positions so that no one trade can cripple their capital, and treat leverage as a tool to be used sparingly rather than maxed out. This calculator shows you the loss on margin from an adverse move alongside the gain, precisely so you can see how quickly leverage can turn against you and size your risk accordingly.
What charges apply to intraday trading?
Intraday equity trading carries a stack of charges, most of them statutory and the same across brokers. First, brokerage, the broker’s own fee, which at discount brokers is typically a flat twenty rupees per order or a small percentage if lower, and at full-service brokers a percentage of turnover. Second, the Securities Transaction Tax, or STT, at 0.025 per cent, charged only on the sell side for intraday, which is a quarter of the delivery rate. Third, exchange transaction charges, a small percentage of turnover levied by the NSE or BSE. Fourth, GST at 18 per cent, charged only on the brokerage and exchange charges, not on the trade value or the STT. Fifth, the SEBI turnover fee, a tiny ten rupees per crore. Sixth, stamp duty on the buy side, at 0.003 per cent for intraday. Crucially, there is no DP charge for intraday, because no shares are delivered to your demat account. Total charges on an intraday round trip typically run around 0.05 to 0.10 per cent of turnover, which sets a breakeven the stock must clear before you profit. Importantly, these charges are computed on the full position value, not on your margin, so on a leveraged trade the charge burden relative to your capital is effectively larger. This calculator itemises every charge for your trade.
What is the breakeven on an intraday trade?
The breakeven is the price move your stock must make just to cover all the charges, before you make a single rupee of profit. Because every intraday trade incurs brokerage, STT, exchange charges, GST, the SEBI fee and stamp duty, the stock has to move by enough to offset all of these before your position is genuinely in profit. For a typical liquid stock, intraday charges are low, so the breakeven is small, often well under a tenth of a per cent of the trade value. But it is not zero, and it matters enormously for traders who scalp very small moves many times a day, because if you are trying to capture moves of only a fraction of a per cent, the charges can consume most or all of your gain, leaving little or nothing after costs. On a leveraged position, while the breakeven as a percentage of the position value is the same, the charges are a larger bite relative to your smaller margin, so the effective hurdle on your capital is higher. Knowing your breakeven before you trade tells you the minimum move you need just to not lose money, which helps you judge whether a setup is worth taking. This calculator computes your breakeven as both a price move per share and a percentage.
How is intraday trading profit taxed?
Profit from intraday equity trading is not treated as a capital gain; it is classified as speculative business income under Section 43(5) of the Income Tax Act, and taxed at your normal income tax slab rate, which for a higher earner can be 30 per cent plus cess. This is quite different from delivery-based equity, where gains are capital gains taxed at concessional rates. Because intraday profit is business income, you must file ITR-3 rather than the simpler forms, and you may be able to deduct trading-related expenses against it. Intraday losses are speculative losses, and they come with a restriction: a speculative loss can only be set off against speculative gains, not against your salary, capital gains or other income, though it can be carried forward for up to four years to offset future speculative gains. This treatment means the net profit this calculator shows is a pre-tax figure; your actual take-home will be reduced by tax at your slab rate. Many intraday traders overlook the speculative-income classification and are surprised at filing time, so it is important to account for it in your expectations and to maintain proper records of all your trades. For your specific tax position, especially if intraday is a significant activity, consult a chartered accountant, who can also advise on deductible expenses and the business-income treatment.
What is the difference between a long and a short trade?
A long trade and a short trade are opposite bets on the direction of a stock’s price. In a long trade, you buy the stock first, expecting the price to rise, and sell it later at, you hope, a higher price; your profit is the exit price minus the entry price, so you make money when the price goes up. In a short trade, you do the reverse: you sell the stock first, without owning it, expecting the price to fall, and buy it back later at, you hope, a lower price to close the position; your profit is the entry price minus the exit price, so you make money when the price goes down. Intraday trading allows both, because positions are opened and closed within the same session, so you can short a stock for the day without needing to borrow it long-term. The charges are the same either way, applied to the buy and sell legs regardless of order, and the tax treatment is identical, both are speculative business income. The key difference is simply the direction you profit from: long for a rise, short for a fall. This calculator lets you select long or short and computes the profit or loss correctly for each, so a short position correctly shows a profit when your exit price is below your entry.
Why do most intraday traders lose money?
A widely cited study by SEBI found that around 7 in 10 individual intraday traders in the equity segment lose money, and for younger traders the loss rate is even higher. The reasons are structural and behavioural. Structurally, charges and the breakeven mean every trade starts slightly negative and must overcome costs before profiting, which is hard when capturing small moves; and leverage, while it amplifies gains, amplifies losses just as much, so a few bad trades on high leverage can do serious damage. Behaviourally, many traders overtrade, take positions too large for their capital, fail to use stop-losses, chase losses with bigger bets, and let emotion override discipline. The market is also highly competitive, with professionals and algorithms on the other side of many trades. None of this means intraday trading cannot be done profitably, some do it well, but it means it is genuinely difficult and unforgiving, and that the casual trader hoping for easy money is very likely to be among the majority who lose. The lesson is not necessarily to avoid intraday trading entirely, but to approach it with realistic expectations, strict risk management, disciplined position sizing, and the humility to recognise that the odds are against the underprepared. This calculator’s honest view of charges, leverage and the downside is offered in that spirit.
Should I use maximum leverage on intraday trades?
No, using maximum leverage is one of the most common and dangerous mistakes intraday traders make. While leverage is capped at around five times for liquid stocks under the current rules, using the full amount available multiplies your risk to the same degree it multiplies your potential reward. At five times leverage, a 20 per cent adverse move wipes out your entire margin, and in practice, with charges and the tendency of losses to compound, serious damage happens well before that. Experienced traders generally use far less than the maximum leverage available, often trading close to unlevered or at low multiples, precisely to survive the inevitable losing trades and stay in the game long enough for their edge, if they have one, to play out. The right amount of leverage depends on your strategy, your win rate, and above all your risk management, but the guiding principle is to size every position so that a single adverse move, even one larger than you expect, cannot cripple your capital. Maximum leverage does the opposite: it ensures that a modest adverse move is catastrophic. This calculator shows you the loss on margin from an adverse move at your chosen leverage, so you can see directly how much more dangerous higher leverage makes each trade, and choose a level you can genuinely afford.
How do intraday charges compare to delivery charges?
Intraday charges are generally lower than delivery charges per rupee traded, chiefly because of the Securities Transaction Tax and the DP charge. For intraday, STT is 0.025 per cent and charged only on the sell side, whereas for delivery it is 0.1 per cent charged on both the buy and the sell, so intraday STT is a small fraction of delivery STT. In addition, intraday has no DP charge, because no shares are delivered to your demat account, whereas delivery incurs a DP charge on the sell. Stamp duty is also lower for intraday, at 0.003 per cent versus 0.015 per cent for delivery, both on the buy side. Brokerage is the same flat fee at discount brokers, and the exchange transaction charge, GST and SEBI fee are broadly similar. So on a single trade, intraday is cheaper in charges than delivery. However, this per-trade saving can be misleading, because intraday traders typically make many trades, each incurring the full charge stack again, and often use leverage, which raises the charge burden relative to their capital. So while intraday is cheaper per trade, an active intraday trader can end up paying far more in total charges than a buy-and-hold delivery investor. This calculator focuses on intraday charges; for a direct comparison of the two, a brokerage calculator that shows both side by side is useful.
Does the tool account for the tax on my profit?
The net profit or loss this calculator shows is after all trading charges, brokerage, STT, exchange charges, GST, the SEBI fee and stamp duty, but it is before income tax on your profit. This is an important distinction. Your intraday profit is speculative business income taxed at your income tax slab rate, so if the tool shows a net profit of, say, ten thousand rupees, and you are in the 30 per cent bracket, your after-tax take-home would be roughly seven thousand, before considering any deductible expenses. The tool does not apply this slab-rate tax because it depends on your total income for the year, your other income, deductions and slab, which are outside the scope of a single-trade calculator, and because intraday profits and losses are aggregated across the year for taxation rather than taxed trade by trade. So treat the tool’s net figure as your pre-tax trading result, the amount your trade actually earned after market costs, and remember that your final take-home will be lower once slab-rate tax is applied on your net annual speculative income. For your overall tax, aggregate your yearly intraday results and apply your slab rate, or use an income tax calculator, and consult a chartered accountant given the business-income treatment and the ability to deduct trading expenses.
What is auto square-off in intraday trading?
Auto square-off is the automatic closing of your intraday positions by your broker near the end of the trading session if you have not closed them yourself. Because intraday, or MIS, positions must be settled within the same day and cannot be carried to the next, brokers automatically square off any open intraday positions, typically between around 3:15 and 3:20 PM, shortly before the market closes at 3:30 PM. This is done at the prevailing market price at that moment, whatever it is, which means you have no control over the exit price on an auto-squared position. This can be costly, especially on illiquid stocks where the price at square-off time may be unfavourable due to low liquidity, causing slippage, the difference between the price you might have wanted and the price you actually got. It can also mean crystallising a loss you were hoping would recover, or missing a better exit. To avoid auto square-off, you should close your intraday positions yourself before the broker’s cut-off time, on your own terms, or convert them to delivery if you have the funds and wish to hold, subject to your broker’s rules and margin. The lesson is to manage your exits actively rather than relying on the broker’s automatic square-off, which prioritises settling the position over getting you a good price.
Can I convert an intraday position to delivery?
Yes, most brokers allow you to convert an intraday, or MIS, position to a delivery, or CNC, position during the trading day, provided you have the full funds to pay for the shares, since delivery requires 100 per cent of the trade value rather than the fraction needed as intraday margin. This can be useful if a trade you intended to close the same day goes against you and you decide you would rather hold the shares and wait for a recovery, rather than book the loss at intraday square-off. By converting to delivery, you take actual delivery of the shares into your demat account and can hold them for as long as you wish. However, there are important considerations: you must have the full purchase amount available, since the leverage that made the intraday position affordable disappears on conversion; converting incurs the delivery charge structure, including the higher STT and the DP charge on eventual sale; and holding a losing position hoping for recovery, rather than accepting a planned loss, is a well-known behavioural trap that can turn a small intraday loss into a large delivery loss. So while conversion is possible and sometimes sensible, it should be a deliberate decision based on your view of the stock and your funds, not a reflex to avoid booking a loss. This calculator computes intraday charges; a converted position would follow delivery rules instead.
Are the results from this tool accurate?
Yes, the calculations are accurate for the inputs you provide, applying the correct gross P&L for long or short positions, the full intraday charge stack at current statutory rates, and the correct treatment of leverage and margin. The tool computes your net profit or loss after charges, your return on both your margin and the full position, the breakeven move, and the symmetric downside of an adverse move at your leverage. The main things to ensure are that your entry and exit prices, quantity and leverage are accurate, and that you select the correct side, long or short. A few caveats: the net figure is before income tax on your profit, which is speculative business income taxed at your slab rate; the exchange transaction charge varies slightly between the NSE and BSE and is revised periodically, so the tool uses a representative rate; brokerage varies by broker and plan, so the presets are typical rather than exact for your account; and the leverage available on a specific stock depends on its volatility and your broker’s risk framework, so the maximum may be less than five times. The tool also does not account for slippage, the difference between expected and actual execution prices, which can be significant on illiquid stocks or at auto square-off. So treat the result as an accurate computation of your intraday trade’s market P&L and leverage effect, verify charges against your broker’s contract note, and account for slab-rate tax separately.
How can I manage risk in intraday trading?
Risk management is what separates intraday traders who survive from those who blow up their accounts, and it matters more than any strategy or stock pick. The foundations are these. First, always use a stop-loss: decide before you enter the maximum you are willing to lose on the trade, and set an order to exit automatically if the price hits that level, so a single trade can never do outsized damage. Second, size your positions by risk, not by greed: a common rule is to risk no more than 1 to 2 per cent of your trading capital on any single trade, which, combined with your stop-loss distance, determines how many shares you should buy, rather than taking the largest position your leverage allows. Third, use leverage sparingly: because it magnifies losses as much as gains, keeping leverage low, or trading close to unlevered, dramatically improves your odds of surviving losing streaks, which are inevitable. Fourth, avoid overtrading: each trade has charges and a breakeven, and taking too many marginal trades bleeds your capital on costs; fewer, higher-conviction setups are usually better. Fifth, never chase losses by increasing your bet size to win back what you lost, a behaviour that turns a bad day into a disaster. And keep records, review your trades, and be honest about whether you have a genuine edge. This calculator helps by showing the real downside of leverage at your chosen level, so you can size positions with the loss, not just the hoped-for gain, firmly in view.
Disclaimer and editorial transparency
This intraday net profit and loss calculator is a free, independent tool from CalcWise.Finance. It computes your gross profit or loss for a long or short intraday equity trade, subtracts the full intraday charge stack, brokerage, the 0.025 per cent sell-side STT, exchange transaction charges, GST on brokerage and exchange charges, the SEBI fee and buy-side stamp duty, with no DP charge, and shows your net result. It expresses that result as a return on the margin you put up and on the full position, computes the breakeven move, and shows the symmetric downside of an adverse move at your leverage, so both edges of leverage are visible.
The calculations are accurate for the inputs you provide, but several figures vary: exchange transaction charges differ slightly between the NSE and BSE and are revised periodically, so the tool uses a representative rate; brokerage varies by broker and plan; and the leverage available on a stock depends on its volatility and your broker, so the maximum may be below five times.
The net figure is before income tax: intraday profit is speculative business income taxed at your slab rate, not a capital gain, filed on ITR-3, with speculative losses offsetting only speculative gains. The tool does not model slippage or auto square-off pricing. It is for informational and educational use, not investment or tax advice. SEBI has found that most individual intraday traders lose money; trade with strict risk management. Verify charges against your broker’s contract note and consult a qualified adviser. Nothing here is financial advice.
