How it works
The margin calculator divides the notional value of your gold position by the leverage ratio. Notional value is lot size × contract size × current price. The result is the margin required in the account currency, typically USD for gold.

What This Calculator Answers and When an Australian Trader Needs It
This calculator answers how much free margin you need to open and hold a gold trade. Australian traders need it to avoid a margin call when volatility spikes, especially with leveraged products offered by brokers like FxPro.
It tells you the minimum deposit for a given lot size and leverage. For example, at 1:500 leverage, a 0.10-lot gold position needs about $85.50 margin (as given). That is a fraction of the notional value.
Use it before entering a trade to see if your account balance can support the position. Also check how much margin remains for other trades, because gold can move sharply during Sydney and London sessions.
The Formula in Plain Words
The formula is: margin = (lot size × contract size × current price) ÷ leverage. For XAU/USD, contract size is 100 oz per lot and price is in USD. So 1.00 lot at 4275.0 has a notional value of $427,500.
You need three inputs: lot size, leverage (e.g., 1:100, 1:500), and the current gold price. The calculator divides the notional value by the leverage to get margin in USD.
If your account currency is not USD, the margin is converted at the current exchange rate. FxPro may apply different leverage caps for gold, so check your account settings.
Worked Example on Gold
Using the given figure: at 1:500 leverage, a 0.10-lot gold position needs about $85.50 margin. Let's verify with the reference price 4275.0. Notional value = 0.10 × 100 oz × 4275.0 = $42,750.
Divide by leverage 500: $42,750 ÷ 500 = $85.50. That matches the given margin. If you traded 1.00 lot, the margin would be $427,500 ÷ 500 = $855.00.
For a 0.50 lot at 1:100 leverage, notional is $213,750, margin is $2,137.50. The calculator performs this instantly, but you should always confirm with your broker's margin requirements.
Common Mistakes and How to Read the Result Correctly
A common mistake is confusing margin with the total amount you can lose. Margin is only a deposit held by the broker, not your maximum loss. A 0.10 lot at 1:500 requires $85.50, but a 10-pip adverse move loses $10.
Another error is using the wrong leverage. If your broker offers different leverage for gold than for forex, enter the correct ratio. FxPro's leverage may vary by entity and instrument.
Read the margin as the minimum required to open the position. If your free margin falls below this level, the broker may close your trade. Always keep a buffer above the margin amount to withstand normal price fluctuations.
Common questions
How much margin do I need for 0.10 lots of gold at 1:500 leverage?
Using the reference price of 4275.0, the margin is approximately $85.50. This is calculated as 0.10 × 100 oz × 4275.0 ÷ 500. If the price changes, the margin changes proportionally.
Does FxPro allow 1:500 leverage on gold for Australian clients?
Leverage depends on the regulatory entity and your account settings. FxPro is licensed by the FCA (UK) and CySEC, not ASIC, so Australian residents deal with an offshore entity. Check the maximum leverage for gold on your specific account before trading.
What happens if my margin level drops too low?
If your equity falls below the required margin, the broker may issue a margin call or automatically close your position. To avoid this, use the margin calculator to ensure you have sufficient free margin, and consider using stop-loss orders.
Is margin the same as the amount I can lose?
No, margin is a deposit, not a loss limit. You can lose more than the margin if the market moves against you. For example, a 0.10 lot with $85.50 margin can lose $100 if gold falls 100 pips. Always calculate your risk separately.
How do I convert the margin to AUD?
If your account is in AUD, divide the USD margin by the AUD/USD rate. For example, $85.50 ÷ 0.6500 = A$131.54. Some brokers may use a different conversion rate, so check your platform's displayed margin.
