Gold Margin Calculator
Work out how much margin you need to open a gold (XAUUSD) position at a given price, lot size, and leverage. It also shows the notional value and the margin requirement as a percentage.
Your inputs
In lots. 1 standard lot = 100 oz.
Enter the ratio, e.g. 100 for 1:100.
Advanced (contract size)
One standard XAUUSD lot = 100 oz.
Results
Margin as a percent of notional (1 / leverage).
About the gold margin calculator
How the formula works
Margin is the deposit your broker locks up to let you control a larger position. It equals the notional value divided by your leverage. The notional value is the gold price times your lot size times the contract size (100 oz per standard lot), so higher prices and larger positions both raise the margin you need.
The margin percentage is simply one divided by the leverage. At 1:100 you post 1% of the notional; at 1:20 you post 5%. Knowing this percentage helps you judge how much free margin a new trade will consume before you place it.
Worked example
Opening 0.10 lots of gold at $2,650 creates a notional of $2,650 × 0.10 × 100 = $26,500. At 1:100 leverage the required margin is $26,500 / 100 = $265, which is 1% of the notional. Drop the leverage to 1:20 and the same trade needs $1,325 (5%). The notional never changes with leverage — only the margin does.
Common mistakes
Margin is not your risk. It is the collateral to open the trade; your actual risk is set by your stop loss, which the position size calculator handles. Also remember that as gold rises, the margin to hold an existing position can grow, and leverage limits often differ between instruments and jurisdictions — always confirm your broker's current rate.
Frequently asked questions
How is margin calculated for gold?
Margin equals the notional value divided by leverage. Notional is price times lots times 100 oz. So 0.10 lots at $2,650 is a $26,500 notional, and at 1:100 leverage the margin is $265.
What does 1:100 leverage mean for gold?
1:100 leverage means you post 1% of the notional as margin. A $26,500 gold position needs $265. Higher leverage lowers the margin but does not change your dollar risk, which is governed by your stop.
Is margin the same as risk?
No. Margin is the collateral required to open a position; risk is how much you lose if the price hits your stop loss. You can post a small margin yet still risk a large or small amount depending on your stop distance and size.
Why did my required margin change?
Required margin moves with the gold price and your position size, and depends on your leverage. As the price rises, holding the same lots requires more margin. Confirm your current leverage with your broker.
