How to Calculate Forex Profit: Pips, Lots and Pip Value
If you have ever closed a trade and wondered whether the number in your account made sense, you are not alone. Working out forex profit is simple once you know the three pieces that go into it: how far the price moved (pips), how big your trade was (lot size), and what each pip is worth in your own currency (pip value). This guide walks through the method step by step, shows two fully worked examples with the numbers written out line by line, and explains how spreads and overnight fees quietly change the total.
The three numbers you need
Every forex profit calculation comes down to a single formula:
Profit = pips gained × pip value per lot × number of lots
Get those three numbers right and the rest is arithmetic. Here is what each one means.
Pips. A pip is the standard unit of price movement. For most currency pairs it is the fourth decimal place, so 0.0001. If EUR/USD moves from 1.0850 to 1.0851, that is one pip. Japanese yen pairs are the main exception: because the yen trades in much larger numbers, a pip is the second decimal place, or 0.01. So USD/JPY moving from 150.00 to 150.01 is also one pip. Many brokers now quote a fifth decimal (or third for yen), called a pipette or fractional pip, worth one tenth of a pip.
Lot size. A lot is simply the number of currency units you are trading. A standard lot is 100,000 units, a mini lot is 10,000, a micro lot is 1,000, and a nano lot is 100. Most retail traders use micro or mini lots because they keep the money at risk manageable.
Pip value. This is how much money one pip is worth for your position, expressed in your account currency. For any pair where the US dollar is the quote currency (the second one shown), such as EUR/USD or GBP/USD, the pip value is a tidy round number: 10 dollars per pip for a standard lot, 1 dollar for a mini lot, and 10 cents for a micro lot. When the dollar is not the quote currency, you have one extra conversion step, covered in the yen example below.
How to calculate forex profit, step by step
Whatever the pair, the same five steps apply.
Step 1 — Find the price difference. Subtract your entry price from your exit price. If you were buying (going long), you want the exit to be higher; if you were selling (going short), you want it lower.
Step 2 — Convert the difference into pips. Divide the price difference by the pip size for that pair: 0.0001 for most pairs, 0.01 for yen pairs.
Step 3 — Work out the pip value for one lot. Multiply the pip size by the lot size. That gives the pip value in the quote currency.
Step 4 — Convert the pip value into your account currency if the quote currency is not the same as your account currency.
Step 5 — Multiply it all together. Pips gained × pip value per lot × number of lots. A positive answer is a profit; a negative one is a loss.
A fully worked example: buying EUR/USD
Imagine you buy one standard lot of EUR/USD at 1.0850 because you expect the euro to strengthen. A few days later you close the trade at 1.0900. Here is the calculation line by line.
Price difference: 1.0900 − 1.0850 = 0.0050
Pips gained: 0.0050 ÷ 0.0001 = 50 pips
Pip value (standard lot): 0.0001 × 100,000 = 10 US dollars per pip
Profit: 50 pips × 10 dollars × 1 lot = 500 US dollars
Because EUR/USD is quoted in dollars, the answer is already in dollars. If your account is held in pounds or euros, convert at the current rate. At a GBP/USD rate of about 1.27, that 500 dollars is roughly £394; at a EUR/USD rate of 1.09 it is about €459. The same move on a mini lot would earn one tenth of that (50 dollars), and on a micro lot one hundredth (5 dollars) — which is exactly why position size matters so much.
The yen twist: buying USD/JPY
Yen pairs need one more step because the dollar is the base currency, not the quote. Suppose you buy one standard lot of USD/JPY at 150.00 and close at 150.50.
Price difference: 150.50 − 150.00 = 0.50
Pips gained: 0.50 ÷ 0.01 = 50 pips
Pip value in yen (standard lot): 0.01 × 100,000 = 1,000 yen per pip
Gross profit in yen: 50 pips × 1,000 yen = 50,000 yen
Convert to dollars at 150.50: 50,000 ÷ 150.50 = about 332 US dollars
The pip move looks identical to the EUR/USD trade — 50 pips — but the profit is smaller because a yen pip is worth less once converted back to dollars. This is the single most common reason two trades of the same size and the same pip gain end up paying out different amounts.
Turning risk into a lot size
Professional traders usually work the formula backwards. Instead of asking how much they might make, they decide how much they are willing to lose, then let that decide the lot size. This is the heart of position sizing.
Say you have a 5,000 dollar account and you never risk more than 2 percent on a single trade. That is 100 dollars. You plan to trade EUR/USD with a 20-pip stop-loss, meaning the trade will close automatically if price moves 20 pips against you.
Maximum loss per micro lot: 20 pips × 0.10 dollars = 2 dollars
Lots you can afford: 100 dollars ÷ 2 dollars = 50 micro lots
That equals 50,000 units, or half a standard lot.
Check it: half a standard lot is worth 5 dollars per pip, and 20 pips × 5 dollars = 100 dollars, exactly your risk limit. The same logic works in pounds or euros — swap the account currency in and keep the pip value in that currency.

What eats into your profit
The formula gives your gross result. Three costs sit between that and the money you actually keep.
The spread is the gap between the buy and sell price. If EUR/USD shows 1.0850 to buy and 1.0849 to sell, you start every trade one pip down. On a standard lot that is 10 dollars gone before the market moves.
Commission is a flat fee some brokers charge per lot instead of, or as well as, a wider spread. It is usually a few dollars per standard lot per side.
Swap, or overnight financing, is charged or paid when you hold a position past the daily rollover. Depending on the interest-rate difference between the two currencies, it can be a small credit or a steady drip of cost that matters a lot for trades held over several days.
Here is how the lot sizes and pip values compare at a glance, for any pair quoted in your account currency.
| Lot type | Units | Pip value per pip | Value of a 50-pip move |
|---|---|---|---|
| Standard | 100,000 | 10.00 | 500 |
| Mini | 10,000 | 1.00 | 50 |
| Micro | 1,000 | 0.10 | 5 |
| Nano | 100 | 0.01 | 0.50 |
A quick word on leverage. In the UK the Financial Conduct Authority caps leverage for retail traders at 30:1 on major currency pairs, and in the US the CFTC and NFA cap it at 50:1 on majors. Leverage multiplies both gains and losses, and the large majority of retail trading accounts lose money over time, so treat the profit figure as only half the picture — the potential loss is calculated in exactly the same way.
Frequently asked questions
What is the difference between a pip and a point?
A pip is the standard fourth-decimal move (0.0001) on most pairs, or the second decimal (0.01) on yen pairs. A point, or pipette, is one tenth of a pip — the fifth decimal your broker may display. Some platforms also use point to mean a full one-unit move in the price, so always check what your broker means before sizing a trade.
Do I calculate profit differently for JPY pairs?
The formula is the same, but two things change. The pip size is 0.01 instead of 0.0001, and because the yen is the quote currency you must convert the pip value back into your account currency using the current exchange rate. That extra step is why a 50-pip yen move usually pays less than a 50-pip move on a dollar-quoted pair.
Why is my real profit smaller than the calculator says?
Almost always because of costs. The spread means you enter slightly out of the money, commission is deducted per lot, and any position held overnight is charged or paid swap. A pure pip calculation shows the gross move; subtract those three costs to see what you actually keep.
