Position size calculator
Gold lot size calculator.
Size an XAUUSD trade from your balance, the risk you accept, and your stop loss. The lot size rounds down to your broker's lot step, so the risk never exceeds your budget.

Almost every MT4/MT5 broker uses 100 oz with a 0.10 pip and a 0.01 lot step. Leave these alone unless your broker's symbol specification says otherwise.

How the lot size is worked out
Your risk budget is your balance multiplied by the percentage you choose to risk. On a standard gold contract (100 oz, quoted to two decimals) one pip is a $0.10 move in price, which is worth $10 on one lot. The lot size is the risk budget divided by the stop loss in pips multiplied by that $10.
Brokers only accept sizes in fixed steps, usually 0.01 lots. The calculator rounds down to that step rather than to the nearest one, so $200 on a 30 pip stop gives 0.66 lots and $198 of risk, never 0.67 lots and $201. Risk and reward are shown at the size you can actually place.
Margin is the lot size times the contract size times the gold price, divided by your leverage. The calculator fills in the live spot price and shows when it was quoted. Your broker's price can differ by a few cents, so type the price your platform shows if you want margin to match it exactly.
