A pip is the unit forex traders use to measure price movement. Lot sizes tell you how many units of the base currency you are trading. Together, they tell you what each move is worth in money. If you cannot calculate pip value, you cannot size a trade safely, so this is the first skill to learn.
What a pip is
For most currency pairs, a pip is the fourth decimal place. EUR/USD moving from 1.0850 to 1.0851 has moved one pip. For pairs quoted in Japanese yen, such as USD/JPY, a pip is the second decimal place, so 150.00 to 150.01 is one pip.
Some brokers quote a fifth decimal place, called a pipette or fractional pip. A price of 1.08505 means half a pip beyond 1.0850. Pipettes make prices more precise, but the pip is still the unit you should use to plan trades.
Lot sizes
A lot is a standard quantity of the base currency. The base currency is the first currency in the pair. In EUR/USD, the base is the euro.
- Standard lot: 100,000 units of the base currency.
- Mini lot: 10,000 units.
- Micro lot: 1,000 units.
- Nano lot: 100 units, offered by some brokers only.
Lot names and sizes vary between brokers, so check your account specification before you trade.
Calculating pip value for a USD pair
When the quote currency is US dollars, as in EUR/USD, the pip value is simple. One pip on a standard lot is worth $10. On a mini lot it is $1. On a micro lot it is $0.10.
The formula is: pip value = lot size × pip size. For a standard EUR/USD lot, that is 100,000 × 0.0001 = $10.
Calculating pip value for other pairs
When the dollar is not the quote currency, the pip value must be converted. For USD/JPY, one pip on a standard lot is 1,000 yen, because 100,000 × 0.01 = 1,000 yen. To convert that to dollars, divide by the current USD/JPY rate. At 150, that is about $6.67 per pip.
Because the rate changes, the dollar value of a pip changes too. Your broker’s platform usually shows the pip value for your position, and you should check it before you enter.
Worked example: how much is a move worth?
Suppose you buy one mini lot of EUR/USD at 1.0850 and the price rises to 1.0880. That is a 30-pip move. On a mini lot, each pip is worth $1, so your profit is about $30 before costs.
If the price falls to 1.0820 instead, that is a 30-pip loss, or about $30 before costs.
Now compare the same move on a standard lot. Thirty pips on a standard lot is $300. The price moved the same amount, but the outcome is ten times larger. This is why lot size matters more than the price move.
Position sizing from a stop-loss
Most traders decide the money they are willing to lose first, then work out the lot size. This is called position sizing.
Worked example: you have a $2,000 account and risk 1% per trade, which is $20. Your stop-loss is 40 pips away on EUR/USD. Risk per pip must be $20 ÷ 40 = $0.50. On EUR/USD, a micro lot is $0.10 per pip, so you would trade five micro lots, or 0.05 of a standard lot.
Working backwards from the money you can lose makes sure a single stop-loss hit does not damage the account. It also means a wider stop requires a smaller lot size.
Common mistakes
- Trading too large. Choosing lot size first, then placing the stop, instead of the other way round.
- Ignoring the quote currency. Assuming $10 per pip applies to every pair.
- Forgetting costs. The spread is a cost on top of the pip move. See our guide to bid, ask and spread.
- Confusing pips with points. Indices and some CFDs use points, and their values differ. Check the contract specification.
Practice exercise
On a demo account, pick one pair and calculate the pip value for a micro, mini and standard lot. Then choose a stop-loss distance and work out the lot size that risks exactly 1% of the demo balance. Place the trade and check that your platform shows the same pip value.

Pip values for common pairs
For a standard lot, the pip value depends on which currency is the quote currency. The table below shows approximate values at typical rates. Your broker’s platform gives the exact figure for your account.
- EUR/USD: about $10 per pip on a standard lot, because the quote is in dollars.
- GBP/USD: about $10 per pip on a standard lot, for the same reason.
- AUD/USD: about $10 per pip on a standard lot.
- USD/JPY: about 1,000 yen per pip, or roughly $6 to $7 at rates near 150.
- EUR/GBP: the quote is in pounds, so one pip is about £10 on a standard lot. Converting that to dollars depends on the current GBP/USD rate.
Pairs where the dollar is the base currency, such as USD/CHF or USD/CAD, are converted in the same way. The rule is to find the pip value in the quote currency first, then convert it to your account currency.
Worked example: a cross pair
Suppose you trade EUR/GBP with one mini lot, and the rate is 0.8600. One pip on a mini lot is 10,000 × 0.0001 = 1 pound. If GBP/USD is 1.2700, one pip is worth about $1.27 in dollars. A 25-pip move would be worth about $32 in a dollar account.
This is why cross pairs catch beginners out. The pip value looks similar on paper, but the dollar value moves with a second exchange rate.
Pips and other instruments
Pips are a forex convention. Gold, indices and some CFDs use different units, often called points or ticks, and each has its own contract size. Gold quoted in dollars per ounce may move in cents, and a one-dollar move on a standard gold contract can be worth a large amount per point. Always read the contract specification for an instrument before you trade it.
Common questions
Why do some brokers quote five decimal places? The extra decimal gives a more precise price, usually called a pipette. The pip value is still based on the fourth decimal for most pairs, so a price of 1.08505 is 0.5 pips above 1.0850.
Does pip value change during the day? For dollar-quoted pairs it stays the same. For cross pairs and yen pairs, it changes with the exchange rate used for conversion.
Is a bigger pip move always a bigger profit? Only if your lot size is the same. The money result is pips multiplied by pip value, so the same 30-pip move on two lot sizes gives two different results.
Worked example: three account sizes
Compare three traders who each risk 1% per trade with a 50-pip stop-loss on EUR/USD. Risk per trade is $100 on a $10,000 account, $500 on a $50,000 account, and $1,000 on a $100,000 account.
For each account, the lot size is risk ÷ (stop-loss pips × pip value per lot). For the $10,000 account: $100 ÷ (50 × $1 per mini lot) = 2 mini lots, or 0.2 standard lots. The $50,000 account trades 10 mini lots. The $100,000 account trades 20 mini lots.
Notice that the trader with the largest account does not trade a larger percentage of their balance. The risk is the same 1% in every case. The size of the position changes, but the decision logic does not.
Calculating the pip value you need
Use this sequence before every trade. First, decide the maximum money you will lose. Second, set the stop-loss in pips, based on the chart. Third, find the pip value per lot for your pair and account currency. Fourth, divide the money at risk by the stop-loss in pips, then by the pip value per lot, to get the lot size.
If the answer is not a size your broker allows, round down. Rounding up increases the risk above your plan.
Pip mistakes that cost money
- Forgetting the spread. A 40-pip stop with a 2-pip spread gives you 38 pips of room before a stop is hit. Check whether your stop is measured from the bid or the ask.
- Using the wrong pair for the lot size. A standard lot of USD/JPY is not worth the same per pip as a standard lot of EUR/USD.
- Ignoring slippage. A stop-loss fills at the next available price, which can be a few pips worse in fast markets.
How this connects to the rest of the learning path
Once you can calculate pip value, the next steps are understanding how leverage sets the margin you need, and how the spread changes the break-even point. Read our guide to naked forex trading to see pips used in a real trading plan, or our demo account guide to practise the calculations safely.
