What is Margin in Forex and How to Calculate it?

Key Takeaways

• Margin in forex is collateral, not a fee. It is the deposit required to open and maintain leveraged trades; for example, 100 to 1 leverage means US$1,000 margin controls a US$100,000 position.

• Margin level in forex is calculated as (equity ÷ used margin) × 100 percent. As margin level falls toward about 100 percent, brokers may restrict new trades or trigger margin call and stop out rules.

• Free margin in forex equals equity minus used margin and shows your capacity for new trades and drawdowns. Used margin is tied up in open positions, so monitoring both is critical.

• Margin calls are risk controls in forex margin trading. When equity drops too low, brokers may warn, restrict new orders or automatically close positions based on their margin level thresholds.

• Understanding how margin works in forex, including margin, free margin, margin level and margin calls. Supports better position sizing, conservative leverage and long term risk management.

What is Margin in Forex? 

Margin in forex trading is the amount of capital a trader must deposit to open and maintain a leveraged position. It is not a fee but collateral set aside to cover potential losses. Margin is usually expressed as a percentage of the total trade size. For example, with 100 to 1 leverage, opening a US$100,000 position requires a US$1,000 margin deposit. This simple example shows how forex margin lets you control larger trades but also increases risk if the market moves against you.
