Margin Calculator — Forex & CFD Trading
Margin is collateral required to open and maintain a leveraged position. It is different from the loss planned at a stop and can change with broker rules, prices or volatility. This tool estimates required margin, not the exact number of pips until forced closure. Cross pairs, tiered margins and different account currencies need conversion or additional rules. Percentage-based stop sizing does not automatically ensure sufficient free margin. Losses consume equity even though margin itself is not a transaction fee.

Why Use the Margin Calculator?
Margin is collateral required to open and maintain a leveraged position. It is different from the loss planned at a stop and can change with broker rules, prices or volatility. Compare the displayed result with the worked example and confirm the assumptions before using it.
Formula Used
USD notional = lots × units per lot × USD price; margin = notional / leverageWorked Example
One standard EUR/USD lot at 1.1000 has $110,000 notional. At 10:1 leverage the required margin is $11,000. An account with $15,000 equity has a $4,000 buffer above used margin. At $10 per pip, that corresponds to 400 adverse pips under constant-margin, no-cost assumptions—not 36 pips.
