The calculation
How XAUUSD position sizing works
Risk budget = account balance × risk percentage.
Ounces = risk budget ÷ stop distance per ounce, after converting USD into the account currency.
Lots = ounces ÷ the broker's contract size. A standard gold lot is often 100 oz, but the field is editable because contracts vary.
Estimated initial margin = notional exposure ÷ leverage. This is only an estimate; the broker's own margin schedule controls the order.
Important distinction
Leverage changes margin, not the stop distance
At the same position size, entry and stop, switching from 1:10 to 1:100 leverage does not reduce the price loss between entry and stop. It reduces the margin reserved for the trade, which can make a much larger exposure look affordable. That is why the result shows both selected leverage and effective exposure relative to the account.
The calculator does not estimate a liquidation price. Maintenance margin, mark price, negative-balance protection, cross-margin treatment and close-out thresholds differ by broker and account.
Questions
XAUUSD calculator FAQ
How do I set entry and stop on the chart?
Select Set entry, click the desired price on the chart, then click again to place the stop. The chart writes both prices into the calculator. You can still type exact values in the fields below.
Does leverage change the loss at my XAUUSD stop?
Not if position size, entry and stop stay the same. Leverage changes the margin required to hold the position. Higher leverage can increase margin pressure and the chance that a broker closes a position before its stop is reached.
What contract size should I use for XAUUSD?
One standard XAUUSD lot commonly represents 100 troy ounces, but mini, micro and broker-specific contracts differ. Check the contract specification in your own trading platform and replace the default when necessary.
Is the planned loss my maximum possible loss?
No. It is the price-distance calculation for the inputs entered. Spread, slippage, commissions, financing, price gaps, currency conversion and broker close-out rules can make the actual loss larger.
What does stop distance in ATR mean?
It compares the distance between entry and stop with the latest available 14-period hourly Average True Range. It describes the stop in units of recent volatility; it does not say that the stop is safe or likely to work.
Does Ampeld store the numbers I enter?
No. The calculator runs in the browser. Account balance, risk, entry, stop, leverage and result values are not sent to Ampeld and are not included in analytics events.
