Risk
1% ($50.00)
Stop loss
200 pips

Risk per lot

200 pips × $1.00 per pip

= Risk / 1.00 lot

$200.00

Position size

$50.00 risk ÷ $200.00 per lot

≈ Lots

0.25 lots

Note: The pip value is already in US dollars, so a USD account gets exactly 0.25 lots. In another account currency the calculator converts the pip value with live rates first.
XAU/USD FAQ

XAU/USD lot size FAQs

How do I calculate the lot size for XAU/USD?

Enter your account balance and currency, choose XAU/USD, set your risk per trade as a percentage (for example 1%), and enter your stop loss. The calculator multiplies balance by risk% to get the money at risk, then divides that by your stop distance times the XAU/USD pip value per lot. When your account currency differs from US Dollar (USD), the pip value is converted with live exchange rates before the lot size is worked out.

What is one pip of XAU/USD worth?

One pip of XAU/USD moves the value of a 1.00 lot by $1.00. This is the contract size (100 oz) multiplied by the pip size (0.01). Because the pair is quoted in US dollars, that pip value is already in dollars.

What is 1 lot of XAU/USD?

A standard 1.00 lot of XAU/USD represents 100 oz. A 0.10 lot is a tenth of that and a 0.01 lot (a micro lot) is a hundredth. Brokers can define contract sizes differently, so confirm the specification in your MT4/MT5 symbol details before sizing a live trade.

Why does the calculator show an exact size and a broker-ready size?

The exact size is the pure mathematical answer, for example 0.0167 lots. Most brokers only accept volumes on a grid set by a minimum lot and lot step (often 0.01), so the broker-ready size is the largest valid volume at or below the exact size. It never rounds up, so your actual risk on XAU/USD never exceeds the risk you set.

Does the XAU/USD lot size depend on my account currency?

XAU/USD is quoted in US dollars, so a USD account needs no conversion. For any other account currency, the calculator converts the pip value with live rates, which can make the same trade look slightly larger or smaller.
