A pip is the standard unit used to describe the smallest conventional price move in a currency pair. Forex rates move in tiny fractions, so traders need a shared vocabulary for discussing price changes, profit and loss, and trading costs. Without it, every conversation about how much a market moved would turn into a debate about decimal places. The pip solves this: it is market convention, not an official standard set by any regulator.

What a pip is

For most major currency pairs, exchange rates are quoted to four decimal places, and a pip is a change in the fourth decimal place. For dollar-based quotes, one pip is one hundredth of a cent. If EUR/USD moves from 1.3000 to 1.3010, the euro has risen by ten pips. If it moves from 1.2500 to 1.2490, the euro has weakened by ten pips against the dollar.

The Japanese yen is the well-known exception. Because the yen trades at a much smaller value per unit than the dollar or euro, yen-quoted pairs such as USD/JPY use two decimal places, and one pip is a change in the second decimal place. So USD/JPY moving from 150.00 to 150.05 is a five-pip move.

Notably, there is no standards body that rules on quoting conventions. The euro takes base-currency precedence by convention dating from its introduction in 1999, and the priority ordering of currencies in pair names is likewise market custom rather than regulation.

Fractional pips and tick size

Most modern platforms quote a fifth decimal place (or a third for yen pairs). That extra digit is a fractional pip, often called a "pipette" — one tenth of a pip. EUR/USD quoted at 1.30005 has moved half a pip from 1.3000.

Do not confuse pips with tick size. A pip is the conventional unit of description; the tick is the smallest increment a specific market or instrument actually moves in. Some instruments tick in half-pips or five-pip increments. The distinction matters when you compare pricing across platforms: two brokers can both display five decimals while quoting different minimum increments.

Calculating pip value

A pip is a price change; a pip value is what that change is worth in money, and it depends on the pair, the position size and, for some pairs, the current rate.

Illustrative example. For a pair quoted in US dollars, one pip on one standard lot (100,000 units) is worth:

0.0001 × 100,000 = 10 USD per pip

A ten-pip move on one standard lot of EUR/USD is therefore 100 USD. On a 0.1-lot (mini) position, the same move is 10 USD; on 0.01 lots, 1 USD. The pip does not change — the money does, because position size scales pip value directly.

Yen quotes. For USD/JPY, one pip is 0.01 JPY per unit of base currency, so one standard lot moves 1,000 JPY per pip. What that is worth in dollars depends on the exchange rate itself:

• At an illustrative USD/JPY of 150.00: 1,000 JPY ÷ 150.00 ≈ 6.67 USD per pip on a standard lot.

• At USD/JPY of 155.00: 1,000 JPY ÷ 155.00 ≈ 6.45 USD per pip.

The pip value of yen-quoted pairs therefore drifts with the rate, unlike the fixed 10 USD figure for dollar-quoted pairs. These figures are illustrative calculations, not quoted values from any broker.

Crosses. For a cross such as EUR/JPY, the pip value in your account currency typically involves two conversions — the pair's quote currency (JPY) and your account currency (say USD) — so pip-value arithmetic generally runs through the USD/JPY rate. At an illustrative USD/JPY of 150.00, one pip on a standard lot of EUR/JPY is again roughly 6.67 USD. Most platforms compute this for you, but knowing the mechanism tells you why displayed pip values change over time.

Pips, position size and risk

Because pip value scales with position size, the same price move produces very different outcomes depending on lot size. A 50-pip adverse move costs 50 USD on one standard lot of a dollar-quoted pair, 5 USD on a mini lot and 0.5 USD on a micro lot. This is why risk management is usually expressed in pips — for example, "stop 30 pips away" — and then translated into money by multiplying by pip value for your actual position size.

That translation is where account currency matters. A trader with a USD account trading USD-quoted pairs enjoys a fixed, easy-to-verify pip value. Traders using other account currencies, or trading crosses and yen pairs, should expect pip values to move and should re-check them rather than assuming yesterday's number still applies.

Leverage changes how much margin a position requires, not the pip value itself. A leveraged position and an unleveraged one of the same size gain and lose the same money per pip; leverage only changes the capital tied up and, with it, how quickly losses can consume the account. Margin mechanics and the point at which a position is force-closed are covered separately in our margin call and stop-out explainer.

Pips and trading costs

Spreads — the gap between a broker's buy and sell prices — are conventionally quoted in pips. A EUR/USD spread of 1.0 pip on a standard lot is effectively a 10 USD round-trip cost, using the same illustrative arithmetic as above: 0.0001 × 100,000 = 10 USD.

This is why spread comparisons should be read together with pip values. A "half-pip" spread on a yen cross is not automatically cheaper than a "1-pip" spread on EUR/USD, because the pip value and the typical position size differ. It also explains the economics of account types: raw-spread accounts quote very low spreads but charge a separate commission, which is usually expressed in currency per lot rather than pips — the same cost, in a different unit.

Forward-market pricing extends the same vocabulary: the time-value adjustment applied to a spot rate in forward FX contracts is quoted in pips (also called FX points or forward points). You will rarely need it as a retail spot trader, but seeing "forward points" on rate sheets now reads as what it is — pip-denominated adjustments, not a separate fee.

Key points to carry away

• A pip is convention, not regulation: fourth decimal for most pairs, second decimal for yen pairs.

• Pip value depends on position size and, for yen and cross pairs, the current exchange rate.

• The same pip move is worth 10x more on a standard lot than a mini lot — always convert pips to your own money.

• Spreads are quoted in pips; compare cost in currency terms, not pip terms alone.

• Platform pip-value displays recalculate as rates move; re-check rather than assume.
