Forex Profit Calculator
One trade has five different profit figures and they are all correct: the number of pips, the money in the pair's quote currency, the money in your account currency, the share of your balance, and the multiple of what you risked. This page works out all five from your lot size, then takes the three costs off — spread, commission and overnight financing — and tells you how far price has to travel before the trade earns anything at all. Nothing about your account is assumed: every number it needs is a field. The fourth tool is the third cost on its own: what one night of holding a position costs, how fast that adds up over a hold, and how many nights it takes before the financing has spent the trade's own target.
Single trade inputs
Switch this if you know the move in pips and not the prices.
Positive in the direction of the trade. A loss is a negative number.
A standard lot is 100,000 units, a mini 10,000 and a micro 1,000. Read it off the symbol specification on your platform rather than assuming it.
0.0001 for most pairs, 0.01 for the yen pairs.
What you pay to get in. The trade is down by this much the moment it is filled.
In your account currency, both sides together. Zero on a spread-only account.
In your account currency, all the nights you held it. Nights held x the per-night figure. Negative if you were paid.
The rate the profit is converted at when the trade is closed. 1 if the quote currency is your account currency.
Only used to express the result as a share of the account.
Only used to express the result in R — the multiple of what you risked. Leave it out and the R row stays blank.
Single trade results
A run of trades, under four sizing rules
Run of trades inputs
Percent of the balance. It sets the size of trade one, which is the size the fixed-lot rules then keep.
1 R means you lost exactly what you risked, which is what a stop is for.
This changes the deepest drawdown, not the ending balance. Both are shown.
Run of trades results
| Rule | Ending balance | Change | Deepest drawdown | Lowest balance |

What costs do to the win rate you need
Cost inputs
Spread plus commission plus financing, per round turn.
Percent. Only used for the expectancy rows, not for the break-even figure.
Cost results
What a held position pays overnight
Financing inputs
Both are in use, and the specification sheet for your symbol uses one or the other.
In your account currency. On a four-decimal pair at one standard lot, one pip is 10 of the quote currency.
This page divides the year by 365 to reach one night. Some firms divide by 360.
What the position is exposed to, not what you deposited. Needed for the yearly rate and for the share rows.
Not always the same number. On many platforms one night of the week is billed three times to carry the weekend, so a five-night hold through it is billed seven.
Financing results
Four rules, three orders, one hundred trades
Starting balance 10,000, risk 1 percent on the first trade, one hundred trades, fifty of them winners, the average winner 2 R and the average loser 1 R. No costs in this table — it is only about sizing. The drawdown column is the deepest fall from the highest balance reached.
| Rule and order | Ending balance | Change | Deepest drawdown |
|---|---|---|---|
| Fixed lots, winners first | 15,000.00 | +50.00% | 25.00% |
| Fixed lots, losers first | 15,000.00 | +50.00% | 50.00% |
| Fixed lots, alternating | 15,000.00 | +50.00% | 0.98% |
| Fixed percent, winners first | 16,284.27 | +62.84% | 39.50% |
| Fixed percent, losers first | 16,284.27 | +62.84% | 39.50% |
| Fixed percent, alternating | 16,284.27 | +62.84% | 1.00% |
| Fixed money, any order | 15,000.00 | +50.00% | same as fixed lots |
| Fixed percent of the starting balance, any order | 15,000.00 | +50.00% | same as fixed lots |
Read down the ending balance column: two numbers, not four. Read across the drawdown column and the orders separate completely — the same run of trades, finishing in exactly the same place, went through a 50 percent hole or a 1 percent hole depending on nothing but the order they arrived in.
One lot, three financing rates, four holds
One standard lot, one point worth 10.00 in the account currency, billed for every night held. The three rates are inputs, not anybody's schedule: 0.50, 2.50 and 5.00 points per lot per night.
| Nights held | At 0.50 a night | At 2.50 a night | At 5.00 a night |
|---|---|---|---|
| 1 | 5.00 | 25.00 | 50.00 |
| 5 | 25.00 | 125.00 | 250.00 |
| 20 | 100.00 | 500.00 | 1,000.00 |
| 60 | 300.00 | 1,500.00 | 3,000.00 |
| Share of the position, over 60 nights | 0.27% | 1.36% | 2.73% |
| Nights before it costs a 500.00 target | 100.00 | 20.00 | 10.00 |
Read the last row before the rest of it. At 5.00 a night the trade has 10.00 nights to reach a 500.00 target before the financing has eaten all of it; at 0.50 a night it has 100.00. The size of the trade decides how much a night costs and the length of the hold decides how many of them there are, and neither of them is in the chart you took the trade from.
The same position at three leverages
Exposure 110,000.00 in every row, financing 25.00 a night in every row. Only the deposit changes.
| Leverage | Deposit held | Financing, per night | Share of the deposit, per night | Nights until it costs the deposit |
|---|---|---|---|---|
| 1:30 | 3,666.67 | 25.00 | 0.68% | 146.67 |
| 1:100 | 1,100.00 | 25.00 | 2.27% | 44.00 |
| 1:500 | 220.00 | 25.00 | 11.36% | 8.80 |
The deposit column falls by a factor of sixteen and two thirds between the first row and the last. The financing column does not move, because it is charged on the exposure and not on the deposit. What moves is everything to its right: at 1:500 the carrying cost has passed the whole deposit after 8.80 nights.
One trade, five correct answers
Take a long on a major pair from 1.1000 to 1.1050 at one standard lot, contract size 100,000, pip size 0.0001, account in the same currency as the quote. That is 50 pips, and 50 pips at 10 a pip is 500. On a 10,000 balance that is 5 percent. With a stop 20 pips away the risk was 200, so the gross is 2.5 R. Take the costs off — 1.2 pips of spread is 12, a 7 commission and 5 of financing is 24 in total — and the net is 476, which is 4.76 percent of the balance and 2.38 R.
None of those five is the "real" one and none of them is wrong. Pips are what the chart shows. The quote currency figure is what the platform computes. The account currency figure is what lands in your balance. The percentage is what it means to you. The R figure is the only one you can compare across trades of different sizes, because it is a ratio and the other four are not. A page that gives you one of them is not lying to you; it is just answering a different question from the one you had.
The trade starts at a loss
You buy at the ask and the mark is the bid, so the instant a long is filled it is down by the spread. Add the commission and any financing and the trade has to travel before it earns anything. In the example above that distance is 2.40 pips: 1.2 pips of spread plus 1.2 pips to cover the 12 of commission and financing at 10 a pip. Against a 50 pip target the costs are 4.8 percent of the move. Against a 10 pip target they are 24 percent of it.
That is the whole argument for putting costs in the same calculation as the profit. A target measured in pips does not know what it costs to reach, and the shorter the target the larger the share of it that goes out again. It is also why the losers are worse than they look: the costs are charged on the losing trades too, so a trade that lost exactly 1 R actually lost 1 R plus whatever the round trip cost.
Leverage is not in the formula
Profit is pips x pip size x contract size x lots. Leverage appears nowhere in it, and no page can put it there. What leverage changes is the size of the lot you are allowed to open, and through that the size of the profit — but the same lot on a 30:1 account and on a 500:1 account earns exactly the same money. Search for a profit calculator with leverage in it and you are usually looking at a margin calculator wearing the wrong label.
The one place leverage reaches the outcome is indirect and it is not in the profit line: it decides how far price can travel before the platform takes the position away from you. That is a different calculation and it lives on the forex margin calculator.
The conversion happens when you close, not when you open
A long on a yen pair from 150.00 to 151.00 at one standard lot wins 100 pips, and with a pip size of 0.01 and a contract size of 100,000 that is 1,000 yen per pip, so 100,000 yen. If your account is in pounds, that is not a fixed number of pounds. It is 100,000 divided by whatever the pound-yen rate is when the trade is closed: 526.32 at 190.00, 531.91 at 188.00. Same pips, same yen, 5.60 more in your pocket, entirely because a rate you were not trading moved by just over 1 percent.
The consequence people miss is on the open position. Floating profit is converted at the current rate, not at the rate when you entered, so an open trade's profit figure in your account currency keeps moving even when the price of the pair does not. If you are measuring a position against a target written in your own currency, the target is not a fixed number of pips.
A long has a floor. A short does not.
The profit formula looks symmetric and the risk behind it is not. A long on EURUSD at 1.1000 has a worst case: the price falls to zero, which is 11,000 pips against you, and there is nothing below that. A short on the same pair at the same price has no worst case at all — 11,000 pips against it puts the price at 2.2000, and the price can keep going. Both directions are leveraged, and only one of them is bounded.
It is the same asymmetry that shows up on the deposit side: a short's required margin rises as the price rises, so a short runs out of room sooner than the long does. That one is measured on the forex margin calculator, where the distance to the stop-out is the answer rather than the profit.
Four sizing rules, two machines
Fixed lots, fixed money at risk, fixed percent of the current balance, fixed percent of the starting balance. People argue about these four as if they were four different things, and when the stop distance is the same on every trade they are two. Fixed money is fixed lots: a fixed sum of money at a fixed number of pips is a fixed number of units, so the lot size is the same each time. Fixed percent of the starting balance is also fixed money, because the starting balance does not move. Only the first and the third behave differently, and the difference is one word: fixed lots adds, fixed percent multiplies.
Adding and multiplying only pull apart over a long run. Over one hundred trades with fifty winners at 2 R and fifty losers at 1 R, starting from 10,000 with 1 percent risked on the first trade, fixed lots ends at 15,000 and fixed percent ends at 16,284.27 — about 8.6 percent more, from the same trades in the same order. That gap is not a better strategy. It is the difference between taking your risk as a fixed sum and taking it as a share of what is left, and it is the only thing on this page that compounding does. The rest of it — how often you work the size out again, and what that interval does to the order your results arrive in — is on the forex compounding calculator.
Order does not change where you end up. It changes the hole on the way.
Run the same hundred trades with all fifty losers first and you finish at exactly the same 15,000, or exactly the same 16,284.27. That is not a coincidence and it is not a rounding artefact: adding is commutative and so is multiplying, so a fixed run of results lands in the same place whatever order it arrives in. Both rules are order-blind on the ending balance.
The drawdown is not. Fifty losers in a row on fixed lots takes a 10,000 balance down to 5,000 before it recovers to 15,000 — a 50 percent drawdown. The identical trades alternating produce a 0.98 percent drawdown. On the percentage rule the same two orderings are 39.50 percent and 1.00 percent. Same trades, same ending balance, and one of them is a run you would have quit in week three.
The practical reading is uncomfortable and worth stating plainly: the ending balance is the least informative number in a track record. Two traders can show you the same curve endpoint and one of them went through a hole that would have ended the account at half its size. Whether you survive the path is a different question from whether the arithmetic pays.
What overnight financing does while you hold
Three costs come off a trade on this page and two of them are charged once. The spread is paid the moment you are filled and the commission is paid with it. The third one is charged again every night the position is still open, which makes it the only cost here that grows while you wait, and the only one whose total depends on how long the trade takes rather than on how it ends.
What is swap in forex?
Swap, the rollover, the overnight financing — the same thing under three names, and it is the cost of holding a leveraged position through the platform's rollover moment, which is conventionally 17:00 New York time. What that moment lands at on your own clock, and why it moves twice a year, is worked out on the forex market hours page. Because the position is leveraged, holding it overnight is borrowing: the interest on the side you are long of against the interest on the side you are short of, plus whatever the firm adds on top. Firms publish it two ways — as a number of points per lot per night, or as a yearly percentage — and the fourth tool above takes either.
How do I calculate swap charges in forex?
In points: the points per lot per night, multiplied by what one point is worth, multiplied by the number of lots, multiplied by the nights you are billed for. As a yearly rate: the position value, multiplied by the rate, divided by 100 to get a year and divided by 365 to get one night, multiplied by the nights billed. The tool does both and takes the rate as a field, because the rate is not a figure this page has: it belongs to the firm and the symbol, it is different in each direction, and it changes daily.
The two tables above are those two formulas on one position. The first one is the part the chart does not show: a rate that looks like nothing per night is 3,000.00 over a two-month hold at the top of the range, and 100.00 nights is not the same trade as 10.00 nights even when the entry, the stop and the target are identical. The point of the tool is not the total. It is the last two rows: what the financing is as a share of the position, and how many nights it takes before the trade's own target has been spent on holding it.
Is swap always a charge?
No, and calling it a fee is where most explanations go wrong. It is a difference between two interest rates with a firm's markup on it, and the sign goes either way. Long of the side that yields more and short of the side that yields less and the position can be paid to be held — which is why the tool has a field for which way it runs instead of assuming a minus, and why the two "nights until" rows go blank when you switch it. The direction is decided by the pair, not by whether the trade is winning, and the same symbol on the same platform on the same night can be a cost one way and a credit the other.
Does leverage reduce the financing?
No, and this is the one place where the two numbers on this page come apart. Financing is charged on the exposure, not on the deposit. Leverage changes the deposit and leaves the exposure alone, so it changes what the carrying cost is measured against and not what the carrying cost is. The second table above is that in three rows: the deposit falls by a factor of sixteen and two thirds from the top row to the bottom, the financing does not move at all, and the last column goes from 146.67 nights to 8.80. Higher leverage does not make a held position cheaper to carry. It makes the same carrying cost a larger share of a smaller deposit. What the deposit is, and how far price can run before it is gone, is measured on the forex margin calculator.
What does swap free mean?
That the overnight financing line is zero, and not that carrying a position costs nothing. Accounts are offered swap free for religious reasons in the main, and the cost does not disappear when it is removed — it moves. Wider spreads, a flat fee per night after a set number of days, a higher commission: the money comes out somewhere, and the only honest comparison is the round turn rather than the financing line. The third tool measures it either way, because it asks what a cost per trade does to the win rate you need and does not care what the cost is called.
How is it different from the spread and the commission?
Those two are charged once, and together they are why a trade starts at a loss — the break-even distance this page reports. Financing joins them in that same distance and then keeps adding to it. Run the example at the top of this page with no financing and the break-even move is 1.90 pips; put one night of 25.00 on it and it is 4.40 pips, because 25.00 at 10.00 a pip is 2.50 pips the trade has to travel before it earns anything. The net figure moves with it: 481.00 becomes 456.00. A target is not a profit until the cost of waiting for it has come off.
What this section does not assume
No financing rate. Firms set their own, they differ by symbol and by direction, and they change daily. Every rate in the tool and in both tables is a field, and the figures they produce are arithmetic on what you put in — not a rate anybody charges.
No assumption about which night is billed more than once, or that any night is. Billing one night three times to carry the weekend is common enough to be worth a field for it and not universal enough to be built in. Which night carries it, and whether it does at all, is your firm's setting.
No year length. This page divides the yearly rate by 365. Firms differ, and some use 360. The difference is small and it is not this page's to choose.
No direction. Whether a position is paid or charged to be held is a field. The two "nights until" rows stay blank on a credit, because nothing is being eaten.
No statement about what any firm does charge, and no recommendation about holding. The tables say what a given rate over a given number of nights costs. Whether a trade worth holding for that long is a trade worth taking is not arithmetic, and this page does not say.
What this page does not assume
No commission, no spread and no financing figure. Every one is a field, because every one of them is a property of an account and a symbol that this page cannot see. Nothing here is averaged, typical or assumed.
No conversion rate. The rate the profit is converted at is a field too, because it is set at the moment the trade is closed and not before. This page does not forecast it and does not fill in a plausible one.
No win rate, no average winner, no average loser. Those are the two middle tools' inputs, and they are yours to enter, not figures this page has an opinion about.
No tax. Whether a profit is taxed, at what rate and in which year depends on where you live and how you are set up, and none of that is arithmetic this page can do. The figures above are gross of any of it.
No slippage and no gaps. Every price here is the price you say you got. A stop is an order that fills where it can, and a gap fills it at a price that never traded — the difference belongs to the market, not to this calculation.
And no recommendation between the sizing rules. The table above shows what each one does to the same trades. Which one you can hold through is not something a calculator can tell you, and this page does not pick one for you.
Frequently asked questions
How do you calculate profit in forex?
Pips x pip size x contract size x number of lots, which gives the profit in the pair's quote currency. Convert it into your account currency at the rate that applies when the trade is closed, then take off the spread, the commission and any overnight financing. The first tool on this page does all four steps and shows each one separately.
How much profit is 50 pips?
It depends entirely on the size. On EURUSD at one standard lot, 50 pips is 500, because a pip is worth 10 at that size. On a micro lot of 0.01 the same 50 pips is 5. On a yen pair the pip size is 0.01 instead of 0.0001, so 50 pips on one standard lot of USDJPY is 50,000 yen. The pips do not carry the money — the lot size and the contract size do.
How do I calculate forex profit with lot size?
That is what the first tool takes as its input. Enter the lot size, the contract size for the symbol and the pip size, then either the entry and exit prices or the move in pips, and it returns the profit in pips, in the quote currency, in your account currency, as a share of your balance and in R. The same fields cover the two things people usually add to that question: the spread goes in its own field rather than being ignored, and the account size is what the share-of-balance row is measured against.
How do I calculate forex profit in pips?
Pips are the distance, not the money: on a four-decimal pair one pip is 0.0001 of the price, and on a yen pair it is 0.01. Set "You have" to "The pips already" and the tool works from the distance alone, which is enough to get the money figure as long as you know the lot size and the contract size. If what you have is a pip count and nothing else, the pips to dollars tables on the pip calculator show what the same count comes to on a micro, a mini and a standard lot — and why the answer on a yen pair changes as the pair moves.
Does leverage change my profit?
Not directly. Profit is pips x pip size x contract size x lots, and leverage is not one of those four. Leverage decides the largest lot you can open, so it changes the profit by changing the size — but a given lot earns the same money on a 30:1 account as on a 500:1 one. What leverage does change is how far price can travel before the platform closes the position, and that is measured on the forex margin calculator.
Is this a forex profit and loss calculator?
Yes — it is the same arithmetic read in both directions. A profit and a loss are the same calculation with the sign the other way: enter a negative number of pips, or put the exit price on the losing side of the entry, and the result comes back negative with the costs still coming off. The costs are why the two directions are not mirror images — on a losing trade they are added to the loss rather than taken off a gain, so a trade that lost exactly what you risked lost slightly more than that.
Why is my broker's profit figure different from my pip count?
Three reasons, and all three are in the first tool. Costs come off: the spread is charged the moment you are filled and the commission and financing come off the top. The conversion is done at the rate when you closed, not the rate when you opened, so the account currency figure is not the quote currency figure divided by anything you saw when you entered. And if the trade is still open, the floating figure is converted continuously, so it moves when the cross moves even if the pair does not.
What is break-even in pips?
How far price has to travel in your favour before the trade is worth more than it cost to put on: the spread in pips, plus the commission and financing divided by the money one pip is worth. In the example at the top of this page it is 2.40 pips. On a wide-spread symbol, a small lot or a trade held for weeks it can be several pips, and every one of those pips is a pip you have to earn before the trade earns anything.
What does R mean?
R is the amount you risked on the trade, and a result in R is the profit divided by it. Risking 200 and making 500 is 2.5 R. It is the only one of the five figures that compares across trades of different sizes, because it is a ratio: 2.5 R on a micro lot and 2.5 R on a standard lot are the same trade. The R row on this page uses the stop distance you enter as the risk, and it reports the net figure, so costs shave a little off the R you would have got on a costs-free calculation.
What is a good R multiple?
The arithmetic side of that question has an answer and the rest of it does not. A result of 2 R on a third of your trades and minus 1 R on the other two thirds comes out level before costs, and costs push the win rate you need above a third. A result of 5 R needs a fifth of them. What the multiple does not tell you is how often a target that far away is reached, and that is the half of the question no calculator can answer — which is why this page reports the multiple and stops there rather than naming one to aim for.
Can this tell me where to put my take profit?
No, and nothing on this page tries to. What it does is the other half: give it a distance and it tells you what that distance earns in money, as a share of your account and in R, after costs. Where the level belongs is a read of the chart and of the trade — the figure this page gives you is what the level is worth once you have chosen it. The risk reward calculator is the page that compares a chosen target against a chosen stop.
How do I calculate profit on gold, XAUUSD?
The same four numbers, with gold's own contract size and pip size in place of the pair's — and those are not standard across brokers, which is why the gold page asks you to read them off your platform rather than filling them in for you. To calculate profit in XAUUSD on this page, put the gold contract size and pip size into the first tool exactly as they appear on your platform. The XAUUSD pip calculator handles the gold specification and the same profit arithmetic on it.
How do I calculate profit in my own currency?
Work it out in the pair's quote currency first, then convert at the rate that applies when the trade is closed. That rate is the "quote currency to your currency" field on this page — an INR account on a dollar pair puts the USD to INR rate there, a GBP account on a yen pair puts the JPY to GBP rate there. If your account is already in the quote currency it is 1 and the two figures are the same. It is not the rate from when you opened the trade, and it is not a rate this page guesses.
What win rate do I need to break even?
Without costs, the average loser divided by the average winner plus the average loser: a 200 winner and a 100 loser needs 33.33 percent. Costs move that line up, because every trade pays them whether it wins or not. At 6 a trade against a 200 winner and a 100 loser it becomes 35.33 percent. The third tool works it out both ways and shows the gap between them. Clearing that line is what makes a strategy worth sizing at all: how much of the account each trade should carry is the Kelly fraction, and what the same edge does to the odds of emptying the account over a long run is on the drawdown calculator.
Does a winning trade always make money?
No. A trade can be right about the direction and still close at a net loss if it did not travel further than its break-even distance. On a 50 pip target with 2.40 pips of costs that needs a move of 2.40 pips; on a 3 pip scalp the same costs make most winners into small losers. This is the main reason a high win rate on very short targets and a modest win rate on long ones can end up in the same place.
Do I need my broker's own profit calculator instead?
For the exact figure that will land in your account, yes. A broker's calculator knows that firm's contract size, its commission schedule, its financing rates and the rate it will convert at, and none of those are things this page can see.
What this page adds is the parts a single figure does not show: the five ways of saying the same result, the break-even distance before the trade earns anything, the fact that the conversion happens at close, and what a run of trades does to a balance under rules that are usually presented as four and are really two. Those are the parts a single number hides.
What is swap in forex?
The cost of holding a leveraged position past the platform's rollover moment, which is conventionally 17:00 New York time. It is the interest difference between the two currencies in the pair, plus the firm's own markup, charged once per night the position stays open. It goes under three names — swap, rollover and overnight financing — and the fourth tool on this page works it out whichever of them you arrived with.
How do I calculate swap charges in forex?
Multiply the financing rate by the size and then by the nights you are billed for. Quoted in points, that is points per lot per night times what one point is worth times the number of lots times the nights. Quoted as a yearly percentage, it is the position value times the rate, divided by 100 and divided by 365, times the nights. The tool takes both forms, and takes the rate itself as a field because it is set by your firm and changes daily.
What is a swap rate?
The number your platform publishes for a symbol — either in points per lot per night or as a yearly percentage. There are two of them, not one: a long rate and a short rate, and they are frequently different in size and sometimes different in sign. The rate moves day to day, it is not the same on every symbol, and it is not a figure this page can look up for you, which is why it is an input here rather than a dropdown.
Is swap charged at the weekend?
No trading happens on Saturday or Sunday, but the financing for those two nights is usually collected anyway, by billing one weeknight three times instead of once. That is a convention rather than a rule: whether your firm does it, and which night carries it, is its own setting, and this page takes the billed nights as a separate field from the nights held so you can put either number in. The bigger weekend cost is not the financing — it is that the market reopens at a price that never traded, which is why a stop does not fill at the level it was set at.
What does swap free mean in forex?
That the overnight financing line on the account is zero. It does not mean carrying a position is free: on a swap-free account the same cost is usually collected somewhere else, as a wider spread, a flat fee per night after a set number of days, or a higher commission. Compare the whole round turn rather than the financing line, which is what the third tool above does when you put the total cost per trade into it.
Does leverage change how much swap I pay?
No. The financing is charged on the exposure, and leverage does not change the exposure — it changes the deposit held against it. On 110,000.00 of exposure at 25.00 a night, the deposit is 3,666.67 at 1:30 and 220.00 at 1:500 and the financing is 25.00 at both. What changes is the share: 0.68 percent of the deposit a night at 1:30, and 11.36 percent at 1:500, where the financing has cost the entire deposit after 8.80 nights.
Is this a swap calculator, a swap fee calculator or a swap rate calculator?
All three names get typed for the same thing, and this is that thing, with one difference: it does not carry a rate table, because a rate that is not yours is worse than no rate at all. Put your own in and it returns the total over the hold, the cost per night, the financing as a share of the position and of the deposit, and how many nights it takes before the cost has passed the deposit or the target. The names that end in "rate calculator" usually mean a page that looks a rate up for you; this one asks you for it.
What is a commission in a forex profit calculation?
A commission is a fixed fee the broker charges on the trade, applied once on the way in and once on the way out (or once for a round trip, depending on the broker's pricing). It is added to the spread cost and to any swap that has accrued, and the three are taken off the gross profit in the order the platform applies them. The page treats the commission as a single number on the round trip; whether the broker splits it between entry and exit is a question of the broker's pricing model, not of the arithmetic.
What is a forex commission calculator?
It is the part of a profit calculation that turns a flat fee per lot into a per-trade cost. The formula is the commission per lot times the lot size, on the way in and on the way out, and the result is taken off the gross profit. The first tool on this page takes the commission as one of the cost lines; enter it there and the page returns the net figure that includes it. A separate page that does only the commission arithmetic is the same calculation, just without the trade attached.
How is commission different from spread?
The spread is the difference between the bid and the ask at the moment the trade fills, measured in pips and converted to money by the lot size. The commission is a fixed fee per lot, set by the broker, independent of the price. Some brokers charge only the spread and no commission; some charge only the commission and a tighter spread; some charge both. The page takes both as inputs and reports them as separate lines on the cost, because they are different things measured in different units.
Knowing what a trade earns is half the question; the other half is what it risks. The forex stop loss calculator turns your entry and stop prices into the size of the position, and the risk reward calculator works out the win rate a given ratio needs before it pays. The size of the trade itself, from the stop and the risk budget, is what the lot size calculator is for.
