Understanding XAUUSD risk and margin
What is XAUUSD?
XAUUSD is the market symbol commonly used for Gold priced in U.S. dollars. A quoted price normally represents the USD price of one troy ounce, while the tradable contract is defined by the broker.
What is risk percentage?
Risk percentage is the share of account balance allocated to the planned loss between entry and stop. It sets a sizing budget; it does not guarantee the order will exit at the exact stop price.
How is Gold lot size calculated?
The calculator converts the price gap to a one-lot stop value using contract size, then divides the risk amount by that value. It does not invent a pip convention.
What is contract size?
Contract size is the quantity of Gold represented by one lot. It directly affects both risk per price move and notional value, so the editable value should match the broker's symbol specification.
Why do broker specifications differ?
XAUUSD contract size, minimum lot, lot step, leverage, margin method, and symbol currency can vary by broker, account type, and jurisdiction. Platform settings must be checked before placing a trade.
How does leverage affect margin?
In the basic estimate, higher leverage reduces margin required for the same position. It does not reduce the planned loss between entry and stop or protect against losses beyond the stop.
Risk amount versus margin
Risk amount is the planned loss at the stop based on position size. Margin is collateral reserved to open the position. They measure different things and may be very different amounts.
Why this remains an estimate
The formulas cannot reproduce every broker's live margin engine or predict gaps, slippage, fees, execution, and currency conversion. Treat the platform's current order details as execution truth.
Frequently asked questions
XAUUSD calculator FAQ
How do I calculate lot size for XAUUSD?
Divide the amount you plan to risk by the value of the stop distance for one lot. Here, one-lot stop value equals stop distance multiplied by contract size and the USD-to-account-currency rate.
How much margin does 1 lot of Gold require?
There is no universal figure. A basic estimate is contract size multiplied by the Gold price, divided by leverage, then converted into the account currency. Broker margin rules can override that estimate.
Does leverage change risk?
Leverage changes estimated margin, not the loss implied by a fixed entry, stop, contract size, and lot size. Higher leverage can nevertheless make it easier to take a larger position, which can increase actual exposure.
Why does my broker show a different margin?
Brokers may apply symbol-specific leverage, tiered margin, currency conversion, markups, or different contract specifications. Your platform's live symbol specification is authoritative for that account.
Is XAUUSD contract size always 100 ounces?
No. One hundred ounces is common, but contract size and symbol settings vary. Check your broker and edit the calculator field before relying on the estimate.
Can this calculator predict losses exactly?
No. Gaps, slippage, fees, execution, currency conversion, and broker rules can make the realized outcome differ from the plan.
