Position Size Calculator

Position size = (Account balance × Risk %) ÷ (Stop loss in pips × Pip value per lot). For a $10,000 account risking 1% ($100) with a 20-pip stop on EURUSD (pip value $10/lot), you get $100 ÷ (20 × $10) = 0.5 lots. This calculator handles the full calculation including pip values for all instruments automatically.

For prop firm challenges, most experienced traders recommend risking 0.5–1% per trade. This gives you enough resilience to survive a losing streak (10–20 consecutive losses) without hitting the daily or max drawdown limit. Use this calculator to find the exact lot size for your account size and stop loss before every trade.

A standard lot = 100,000 units of the base currency (1.0 lot). A mini lot = 10,000 units (0.1 lot). A micro lot = 1,000 units (0.01 lot). For EURUSD, the pip value per standard lot is ~$10. For mini lots it's ~$1. For micro lots it's ~$0.10. This calculator shows your lot size in all three formats.

Gold (XAUUSD) is quoted in USD per troy ounce. One standard lot = 100 oz. The "pip" for Gold is typically $0.01 (one cent per ounce), but Gold moves in much larger price increments than Forex pairs — commonly $1–$5+ moves in a session. Stop losses for Gold are usually set in dollar amounts or price distances rather than pips.

Most risk management frameworks recommend no more than 1–2% risk per trade for experienced traders. For beginners, 0.5% is a safer starting point. Higher risk levels (3%+) require very high win rates and consistent execution to avoid large drawdowns and are generally not recommended for prop firm challenges.
