How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or cost – it is a security deposit held by your broker while your trade is open. It allows you to control a larger position with a smaller amount of capital. For example, with 1:100 leverage, you only need 1% of the trade size as margin.
Margin Formula
Margin = (Contract Size × Number of Lots × Price of Instrument) ÷ Leverage. For USD-denominated accounts, if you trade EUR/USD at 1.1000 with 1 lot (100,000 units) and 1:50 leverage, margin = (100,000 × 1 × 1.1000) ÷ 50 = 2,200 USD.
Example for Seychelles Traders
Suppose you want to trade 0.5 lots of GBP/USD at 1.2500 with 1:30 leverage. Margin = (100,000 × 0.5 × 1.2500) ÷ 30 = 2,083.33 USD. You must have at least this amount in your account, funded via Bank Transfer or USDT, to open the trade.
Important Terms
Used Margin – the total margin currently used for open positions. Free Margin – the amount available to open new trades. Margin Level = (Equity ÷ Used Margin) × 100%. If margin level falls below 100%, you risk a margin call.
