Pip

A pip is the standard unit of price movement in a forex pair — the smallest increment a quote conventionally ticks, which for most pairs is the fourth decimal place, 0.0001. For pairs quoted against the Japanese yen it's the second decimal, 0.01, because yen prices carry fewer digits. Many brokers now quote one extra digit past the pip, a fractional pip called a pipette (a tenth of a pip), so EUR/USD showing 1.08453 has priced to the half-pipette. Pips are the common language of forex: spreads, stops, and targets are all measured in them.

How it's calculated

A pip's value in money depends on the pair, the exchange rate, and how large your position is. Price movement alone means nothing until you convert it to your account currency.

Work EUR/USD first. One standard lot is 100,000 EUR, pip size is 0.0001, and the quote currency is USD. Because USD is already the currency you're measuring in, the exchange-rate term drops out: pip value = 0.0001 × 100,000 = $10 per pip. A 20-pip move on one lot is $200. On a mini lot (10,000 units) it's $1 per pip; on a micro lot (1,000 units) it's $0.10.

USD/JPY is where the formula earns its keep. Pip size is 0.01, contract size 100,000, and say the rate is 145.00. Pip value in USD = (0.01 ÷ 145.00) × 100,000 = $6.90 per pip on a standard lot. Notice you divide by the exchange rate here because the pip's value lands in JPY (the quote currency) and has to be converted back to USD. As USD/JPY drifts, so does the per-pip value — it isn't a fixed $10 the way a USD-quoted pair is.

Why it matters

Pips normalize price moves so you can compare and act on them regardless of the instrument. A 30-pip range on EUR/USD and a 30-pip range on GBP/JPY are the same distance in pips but very different amounts of money — and only by converting each to money do you know what you're actually risking. That conversion is the hinge of every risk decision you make.

Once you can price a pip, position sizing becomes arithmetic instead of guesswork. Decide the money you'll risk, measure your stop distance in pips, and the pip value tells you how many lots that stop can support. Risk $200 with a 20-pip stop on EUR/USD and you can hold one standard lot ($10 × 20 = $200); halve the stop to 10 pips and the same $200 supports two lots. Stop placement and size are two ends of the same pip calculation, which is why traders quote their stops in pips first and money second. A position size calculator runs the conversion for any pair once you enter your account risk, stop distance, and lot size.

Pips connect directly to how much you're actually trading: your lot size sets the multiplier that turns pips into dollars, and leverage determines how large a position — and therefore how many dollars per pip — your capital can control. Both feed into margin, the collateral your broker holds against the position you've sized in pips.

Where pips pay off is in the record. Logging every stop and target in pips alongside the realized money outcome in the Tradeways journal shows whether your real per-trade risk matches the plan — the pip is the unit that makes those numbers comparable across pairs, dates, and position sizes.
