Leverage & Margin Calculator

This forex margin calculator shows exactly how much collateral every trade consumes at different leverage ratios, so you know your free margin before clicking buy or sell. Select your account balance, lot size, and broker leverage to see required margin, margin level, and breathing room for multiple positions.

Use it alongside the position size calculator to plan how aggressive you can be without triggering a margin call. Keeping margin usage below 50%—as we teach in the risk management module—helps you survive volatility spikes and news events.
