What is a pip on gold (XAU/USD)?
With most forex brokers, spot gold (XAU/USD) is quoted to two decimal places, so one pip is a price move of 0.01 - for example, from 2400.00 to 2400.01. That means a full one-dollar move in the gold price, say from 2400.00 to 2401.00, is 100 pips. This trips up traders who assume a pip on gold behaves like the 0.0001 pip on EUR/USD; on gold the pip is far larger in price terms because gold itself is a high-priced instrument.
There is one important caveat: conventions vary between brokers. A minority quote gold to one decimal place, and some traders and platforms informally call a whole one-dollar move a pip. Because of this ambiguity, the safest habit is to check how your broker quotes XAU/USD and to think in terms of the actual price move and the money it represents, rather than arguing about the label.
The pip value formula for gold
Pip value on gold depends on two things: the pip size (0.01 for a two-decimal quote) and your contract size, measured in troy ounces. A standard lot of XAU/USD is 100 troy ounces. The core formula is: pip value = pip size multiplied by the number of ounces you are trading.
For one standard lot (100 oz): 0.01 multiplied by 100 equals 1 USD per pip. So each 0.01 move is worth about 1 USD, and a full one-dollar move in gold (100 pips) is worth about 100 USD on a standard lot. These are illustrative figures.
Scaling down: a mini lot is 10 ounces, giving roughly 0.10 USD per pip, and a micro lot is 1 ounce, giving roughly 0.01 USD per pip. Because XAU/USD is quoted in US dollars, the pip value is already in USD - if your account is in another currency, convert it at the current rate, or let our pip value calculator do it for your exact lot size and account currency.
Worked example: sizing a gold trade
Suppose gold is trading at 2400.00 and you want to place a stop-loss 300 pips away, at 2397.00 (a 3.00 move in price). You are willing to risk a fixed cash amount on the trade.
First fix your pip value. On one mini lot (10 oz) that is about 0.10 USD per pip. With a 300-pip stop, your risk is 300 multiplied by 0.10, which is about 30 USD. On one standard lot (about 1 USD per pip) the same 300-pip stop would put roughly 300 USD at risk. Both numbers are illustrative.
Notice the pip distance to the stop stayed the same - only the lot size, and therefore the money at risk, changed. That is the whole point of calculating pip value first: you keep your trade idea and stop constant, then choose a lot size so the distance to your stop multiplied by pip value equals the amount you are prepared to lose.
Why gold pip value matters more than on FX majors
Gold is far more volatile than most currency pairs. It is common for XAU/USD to move several dollars - hundreds of pips - in a single session, and much more around US data releases. Because each pip already carries meaningful value, a position size that feels reasonable on EUR/USD can put a dangerous amount at risk on gold.
The practical rule is to size gold positions down. Work out your pip value, decide your stop distance in pips (gold usually needs a wider stop than a major pair to survive normal noise), and then pick a lot size that keeps the total risk to a small, fixed percentage of your account. Our position size calculator does this backwards from a pip-based stop for you.
Leveraged trading in gold carries a high risk of loss, and its speed is exactly why knowing your pip value in advance - rather than discovering it after a fast move - is one of the few protections genuinely within your control.
