Position Size Calculator
Calculate the ideal position size for any trade based on your account balance, risk tolerance and stop-loss distance.
Position sizing determines how much of your account you risk on each trade. Proper sizing ensures no single loss can significantly damage your account. It is the cornerstone of professional trading — correct position sizing lets you survive losing streaks and stay in the game.
Position Size = Risk Amount / (SL Distance × Pip Value). First determine how much you can afford to lose (e.g., 1% of account). Then divide by the monetary risk of your stop-loss. This gives you the number of lots or units.
Conservative: 0.5–1% per trade. Moderate: 1–2%. Aggressive: 2–3%. Never risk more than 3–5% on a single trade. With 1% risk, you can handle 20 consecutive losses before losing 20% of your account, keeping you in the game long enough to recover.
