This XAUUSD lot size calculator estimates volume from your risk, stop distance and pip value per lot. Broker contract size, pip convention, minimum volume and volume step can differ, so confirm your symbol specification in MT4/MT5 before trading.
XAUUSD Lot Size Calculator is part of the free Aurex Trader calculator suite — 23 browser-based tools for gold (XAUUSD) and forex traders. Nothing is installed, no account is required, and every calculation runs locally in your browser.
Formula: XAUUSD Lots = Risk Amount ÷ (Stop-Loss Pips × Broker pip value per 1.00 lot) Example: $10,000 balance × 1% = $100 risk. On a 100-ounce contract, a $10 price stop risks $1,000 per 1.00 lot, so the estimated size is 0.10 lot. That stop is 100 pips at $0.10/pip or 1,000 pips at $0.01/pip; use your broker's matching pip value.
Pip conventions vary by broker and platform. This calculator requires you to enter your broker's pip value per 1.00 lot; confirm tick size, tick value, contract size and minimum volume in MT4/MT5 symbol specifications.
Pip value depends on the broker's contract size, quoted pip convention and account currency. Use your broker's symbol specification rather than assuming one universal value.
There is no universal safe lot size. Calculate volume from your risk limit, stop distance, broker pip value, contract size and minimum lot; if the result is below minimum, do not round up beyond your risk budget.
Gold contract size and pip value can differ from FX pairs and vary by broker, so use the broker-specific inputs rather than a universal assumption.
No universal contract specification applies to every XAUUSD symbol. Verify contract size, tick/pip value, minimum volume and lot step with your own broker before placing an order.
