XAUUSD Lot Size Calculator for Gold

How the XAUUSD lot size calculator works

On gold, every USD 1 move in the price changes the value of one standard lot by USD 100, because a standard lot is usually 100 ounces. So the XAUUSD lot size calculator does this:

1. Amount at risk = balance × risk % ÷ 100
2. Loss per lot = stop distance in dollars × 100
3. Lot size = amount at risk ÷ loss per lot, rounded down to 0.01

“Stop distance in dollars” is the gap between your entry price and your stop price. An entry at 3,000.00 with a stop at 2,995.00 (example prices) is a USD 5.00 distance.

Worked examples

Example 1. Balance USD 1,000, risk 1%, stop USD 5.00.

• Amount at risk: USD 10
• Loss per lot: 5 × 100 = USD 500
• Lot size: 10 ÷ 500 = 0.02 lots

Example 2. Balance USD 2,500, risk 0.5%, stop USD 8.00.

• Amount at risk: USD 12.50
• Loss per lot: 8 × 100 = USD 800
• Lot size: 12.50 ÷ 800 = 0.0156, rounded down to 0.01 lots

Rounding down means your real risk is a little below what you entered, never above it. The examples use small percentages to keep the arithmetic simple; the figure you use is your decision.

Why “pips” on gold confuse people

Websites and platforms don’t agree on what a gold pip is. Some call a 0.01 move a pip; others call a 0.10 move a pip. That is why “how much is a pip on gold” gets different answers. The dollar values themselves are not in dispute:

Price move	Value per standard lot (100 oz)	Value per 0.01 lot (1 oz)
0.01	USD 1	USD 0.01
0.10	USD 10	USD 0.10
1.00	USD 100	USD 1

This calculator avoids the problem by asking for the stop distance in dollars, which reads straight off your chart. Our gold pip value guide sets the definitions side by side with a full worked example.

How to read the result

• Position size is in standard lots. It goes in the volume field of your order.
• Amount at risk is what you lose if your stop is hit at exactly that price. Spread and slippage can add to it, gold’s price can move quickly, and it can gap past your stop over a weekend or on news.
• A result below 0.01 lots means even the smallest standard position risks more than you chose. See the cent account note below.

The calculator tells you what size fits your stop. It can’t tell you whether the stop is in a sensible place.

Gold contract details to check

• Contract size: one standard lot is usually 100 ounces. Check the contract size in your platform’s symbol specification; if it differs, replace 100 in the formula with your contract size.
• Symbol name: gold usually appears as XAUUSD, sometimes with a suffix or as GOLD. See what is XAUUSD.
• Cent accounts: where one cent lot equals 0.01 standard lots, a cent lot is 1 ounce, and balances show in US cents (USD 5 = 500 USC). Enter your balance in dollars (USC ÷ 100) and multiply the result by 100 to get cent lots. With USD 50, 1% risk and a USD 5 stop, the result is 0.001 standard lots, which is 0.1 cent lots. Check the smallest volume your platform accepts.
• Margin: leverage changes how much margin a gold position ties up, not the loss per dollar of movement. See the margin calculator.

On Exness accounts

• On Standard accounts gold appears as XAUUSDm. The “m” is a suffix Exness adds to symbols on that account type.
• On Standard Cent, one cent lot equals 0.01 standard lots, which is 1 ounce.
• Check the contract size in the symbol specification before your first gold trade.
