What Is a Pip in Forex?
A plain-English explanation of what a pip is, how it is calculated, and why it is the basic unit every forex trader needs to understand.
LEARN
A pip is the standard unit used to measure a price movement in forex. The word is short for “percentage in point” (or sometimes “price interest point”), and it represents the smallest conventional increment that most currency pairs move in. If EUR/USD moves from 1.1000 to 1.1001, that is a one-pip move.
Where the pip sits in the price
For most currency pairs, a pip is the fourth decimal place in the quoted price (0.0001). So if GBP/USD goes from 1.2650 to 1.2680, that is a 30-pip move. The main exception is pairs that include the Japanese yen, which are quoted to two decimal places instead of four — for those pairs, a pip is the second decimal place (0.01). If USD/JPY moves from 149.50 to 149.80, that is also a 30-pip move, just measured at a different decimal position because of how the pair is quoted.
Pipettes: the decimal place beyond a pip
Many brokers now quote prices with an extra decimal place beyond the standard pip, called a pipette or “fractional pip.” On a non-yen pair, this is the fifth decimal place (0.00001); on a yen pair, it is the third (0.001). So EUR/USD might be quoted as 1.10005 rather than simply 1.1000, with that final digit representing a tenth of a pip. Pipettes allow for more precise pricing, particularly on very tight spreads, but the whole pip remains the standard unit traders use when discussing price movement and profit or loss in round terms.
Why pips matter: converting them into money
A pip only becomes meaningful once you know what it is worth in your account currency, which depends entirely on the size of your position. In very simplified terms, pip value is calculated from the size of a single pip movement (0.0001 for most pairs) multiplied by the number of units of base currency you are trading, then adjusted for the current exchange rate. In practice, you do not need to do this math by hand — every trading platform displays the pip value for your chosen position size before and after you open a trade. What matters is understanding the relationship: a larger position size means each pip of movement is worth proportionally more money, which is exactly why position sizing, covered in a separate article in this series, is such an important part of managing risk.
A simple example
Say you open a trade on EUR/USD with a position size where each pip is worth $10, and the price moves 25 pips in your favor before you close the trade. Your gain is $250, before accounting for any spread or commission cost. If the price had moved 25 pips against you instead, your loss would be the same $250. The pip is simply the ruler; your position size determines how much each mark on that ruler is actually worth to your account.
Why traders talk in pips instead of percentages
You might wonder why forex traders talk in pips rather than simple percentage moves, the way price changes are often described in other markets. Part of the answer is precision: currency pairs typically move in very small increments compared to their overall price, so a percentage figure would often be an inconveniently small decimal. Pips give traders a consistent, whole-number way to describe and compare price movement across different currency pairs, regardless of how each pair happens to be priced. It also makes it easier to standardize concepts like stop-loss distance and risk-to-reward ratios in a way that works the same whether you are trading EUR/USD or USD/JPY.
Getting comfortable reading pip movements is one of the first practical skills in forex trading, because almost every other concept covered in this series — spread, slippage, risk-to-reward, stop-loss placement — is ultimately expressed in pips.
