In forex trading, a pip is the standard unit for measuring how much a currency pair’s price has moved. For most pairs it sits in the fourth decimal place, so a shift in EUR/USD from 1.0500 to 1.0501 is one pip. The name stands for “percentage in point” or “price interest point,” and every spread, stop-loss, and profit target you’ll see in forex is counted in these small increments.
Where the Pip Sits on a Price Quote
For nearly all currency pairs, a pip is 0.0001, or one ten-thousandth of a unit of the quote currency. A quote of 1.1050 that ticks up to 1.1051 has moved one pip. A drop from 1.1050 to 1.1035 is fifteen pips. The rule holds across major pairs like EUR/USD, GBP/USD, and AUD/USD, and across most minors and exotics.
Yen Pairs Are the Exception
Currency pairs that include the Japanese yen are quoted to two decimal places rather than four, because a single yen is worth far less than a dollar or euro. A pip on a yen pair lives in the second decimal spot. A move in USD/JPY from 150.00 to 150.01 is one pip, equal to 0.01 yen. Apply the four-decimal framework to a yen pair by mistake and your position sizing and risk math will be off by a factor of 100.
Pipettes and the Fifth Decimal
Most modern brokers quote one digit past the standard pip: a fifth decimal for regular pairs and a third for yen pairs. That extra digit is a pipette, worth one-tenth of a pip. A EUR/USD quote of 1.10505 shows five pipettes past the last full pip. Brokers usually display the pipette in a smaller font so the pip digits stay visually distinct. The practical benefit is finer pricing. A broker can quote a 1.2-pip spread instead of rounding up to 2, which adds up over hundreds of trades.
Calculating What a Pip Is Worth
The formula is direct: multiply the pip increment by your position size. For most pairs the increment is 0.0001; for yen pairs it’s 0.01.
For a standard lot of 100,000 units of EUR/USD:
0.0001 × 100,000 = $10 per pip
That $10 figure applies to any pair where the U.S. dollar is the quote currency (the second currency listed), because the pip is already measured in dollars. A ten-pip gain on one standard lot of GBP/USD earns $100; a ten-pip loss costs $100.
When the Quote Currency Isn’t the Dollar
Pairs like EUR/GBP or AUD/CAD give you a pip value in the quote currency, not in dollars, so you need one more step. First, calculate the pip value using the same formula. For a mini lot (10,000 units) of EUR/GBP, one pip equals 1 GBP. Then convert that into your account currency using the current exchange rate. If GBP/USD is trading at 1.2700, that 1 GBP pip is worth $1.27 in a dollar-denominated account. Missing this conversion is a common source of position-sizing errors.
How Lot Size Multiplies Every Pip
The size of your position acts as a multiplier on every pip of movement. Brokers typically offer four tiers:
- Standard lot, 100,000 units: $10 per pip on USD-quoted pairs.
- Mini lot, 10,000 units: $1 per pip.
- Micro lot, 1,000 units: $0.10 per pip.
- Nano lot, 100 units: $0.01 per pip, offered by some brokers.
The pip itself never changes; it’s still 0.0001. But moving from a micro lot to a standard lot multiplies the financial impact of each pip by a hundred. That’s where risk management actually happens: picking a lot size so that a 30-pip stop-loss translates into a dollar loss you can absorb.
Spreads Are Measured in Pips Too
The bid-ask spread on a pair is quoted in pips and is your primary trading cost. If GBP/USD shows 1.3089 bid and 1.3091 ask, the spread is 2 pips. You start every trade 2 pips behind, because you buy at the ask and could only immediately sell at the bid. Major pairs like EUR/USD often trade under 1.5 pips during peak hours; exotic pairs can widen to 10 pips or more.
Spreads also widen during low-liquidity periods (overnight in the pair’s home time zone, weekends, holidays) and around major economic releases like central bank rate decisions or employment reports. A trade entered just before a high-impact news event can face a spread two or three times wider than normal.
A Worked Example
Say you buy two mini lots of EUR/USD at 1.10250 and price rises to 1.10400. The move is 15 pips: 1.10400 minus 1.10250 is 0.00150, and 0.00150 divided by 0.0001 is 15. Each mini lot pays $1 per pip, and you hold two, so the gross profit is 15 × $1 × 2 = $30. If the spread on entry was 1.3 pips, that entry cost $1 × 2 × 1.3 = $2.60, leaving $27.40 before any separate commissions.
The same 15-pip move on two standard lots would produce $300; on two micro lots, $3. The pip count is identical in each case; lot size drives the outcome. Once the arithmetic is familiar, you can work backward from risk: decide the dollar amount you’re willing to lose, divide by the pip value per lot, and that gives you how many lots to trade for a given stop-loss distance.
