Position Size Calculator

Calculate the correct lot size for any trade based on your account size and risk tolerance.

Why Position Sizing Matters

Position sizing is one of the most important — and most overlooked — aspects of forex risk management. Trading too large a position relative to your account balance is the primary reason retail traders blow up their accounts. The 1–2% rule (never risk more than 1–2% of your account on a single trade) is the industry-standard starting point for disciplined risk management.

How the Calculator Works

Enter your account balance, the percentage of your account you are willing to risk on this trade, your stop-loss distance in pips, and the current exchange rate. The calculator determines the maximum position size (in lots) that keeps your risk within the specified percentage of your account.
