How Much Margin Does an XAUUSD Trade Need?
The margin for a gold trade is the position's value divided by the leverage your account gets on gold — and the second half of that sentence is the part no public page can tell you, because leverage is set per account group, not per symbol. So this guide does what can honestly be done: it works the exposure from the published contract, shows the margin at three assumed leverage ratios so you can see the shape of it, and then makes the point that matters more than any of those numbers. Margin is not the most you can lose.
Step one: exposure, from the published contract
Ultimo's contract specifications (31 August 2026 export) list XAUUSD with a contract size of 100 — one lot is 100 troy ounces — quoted to two decimals, with orders from 0.01 to 20 lots. Use a round gold price of USD 3,000 per ounce for the arithmetic; it is a teaching number, not a quote.
Exposure = lots × 100 oz × price
| Lots | Ounces | Exposure at USD 3,000 |
|---|---|---|
| 0.01 | 1 | USD 3,000 |
| 0.10 | 10 | USD 30,000 |
| 1.00 | 100 | USD 300,000 |
Exposure is what moves with the gold price. It is the number your P&L is calculated on, regardless of how much margin the broker reserves.
Step two: margin, at an assumed leverage
For a straightforward USD account with no fixed-margin override:
Margin = exposure / leverage
| Lots | Exposure | at 20:1 | at 50:1 | at 100:1 |
|---|---|---|---|---|
| 0.01 | USD 3,000 | USD 150 | USD 60 | USD 30 |
| 0.10 | USD 30,000 | USD 1,500 | USD 600 | USD 300 |
| 1.00 | USD 300,000 | USD 15,000 | USD 6,000 | USD 3,000 |
Every ratio in that table is an assumption. Your account's gold leverage is in the platform (Specification window → margin) and in your account terms; a dropdown in a calculator is not evidence of it. MetaQuotes also documents several margin calculation modes — fixed margin, percentage, multipliers for hedged positions — that can change the simple formula. The margin calculator uses the simple formula and says so.
Step three: the point that matters
Take the 0.10-lot position: 10 ounces. Gold moves USD 10 an ounce against you; you are down USD 100. Moves USD 50; down USD 500.
| Adverse move | Loss on 0.10 lot |
|---|---|
| USD 10 / oz | USD 100 |
| USD 30 / oz | USD 300 |
| USD 50 / oz | USD 500 |
Those losses are identical whether the position needed USD 300, USD 600 or USD 1,500 of margin to open. Leverage decides how much of your money is reserved; it does not decide how many ounces you hold or how much they can lose. A USD 300 margin on a position that can lose USD 500 in an afternoon is the whole story of leveraged gold, and Ultimo does not offer negative-balance protection — a large enough gap can leave an account owing.
Sizing from the stop, not from the margin
The professional way round: decide the loss you accept, decide the stop distance, and let those two produce the size.
Accept USD 100 of loss; stop USD 20 an ounce away.
Lots = 100 / (20 × 100) = 0.05 lot
Five ounces, USD 15,000 of exposure at USD 3,000. At an assumed 50:1 that is USD 300 of margin. The USD 100 is the planned loss if the stop fills at its level; a gap through it costs more, and spread and swap sit on top. The position-size calculator does this sum; the margin calculator does the other one. They answer different questions and both are worth running before a gold trade.
Points and pips on gold
XAUUSD is quoted to two decimals, so one point is USD 0.01 an ounce — USD 1 on one lot, USD 0.10 on 0.10 lot. "Pip" means different things in different gold tools (some call USD 0.10 a pip, some USD 1); say "dollars per ounce" and nobody is confused. The same export lists a minimum stop distance of 50 points, which is USD 0.50 an ounce — an order-placement rule, not a suggestion for where to put a stop.
Before you rely on any estimate
Check the live symbol's contract size and margin mode, your account's actual leverage or margin rate, and what you already have open: MetaQuotes' OrderCalcMargin — the function behind most calculators — explicitly ignores existing positions and pending orders. A second gold position does not necessarily cost the same margin as the first.
Frequently asked questions
What is the margin for 0.01 lot of gold? At USD 3,000 and an assumed 50:1, USD 60. Yours depends on your account's leverage.
I deposited USD 100 — can I open a gold trade? Possibly, at high leverage, in tiny size. Whether you should is a sizing question, not a deposit question.
Does higher leverage make the position lose faster? No. Same ounces, same loss per dollar move. It lets you hold more ounces for the same money, which is where the risk comes from.
Can I use the calculator's default leverage? Only if it matches your account. Change it to your real figure first.
