How to Calculate Margin in Forex
Understanding Margin in Forex
Margin is not a cost—it is a deposit that your broker holds as collateral while your trade is open. The required margin depends on three factors: trade size (lot size), contract size (usually 100,000 units for standard lot), and leverage. For example, with 1:100 leverage, you only need 1% of the total trade value as margin.
Margin Calculation Formula
The formula is simple: Required Margin = (Lot Size × Contract Size) / Leverage. If you trade 0.1 lots (10,000 units) of EUR/USD with 1:200 leverage, the margin is $50. For 1 standard lot with 1:50 leverage, margin is $2,000. Always use the base currency (USD) for calculations.
Real Example for Mali Traders
Suppose you deposit $500 via Skrill into your forex account and use 1:100 leverage. You want to trade 0.5 lots of USD/JPY. Lot size = 50,000 units. Margin = 50,000 / 100 = $500. This means your entire balance is used as margin, leaving no free margin—risky. For safety, use only 1-2% of your account per trade.
Free Margin and Margin Level
Free margin is the amount available to open new trades. Margin level = (Equity / Used Margin) × 100%. If your margin level falls below 100%, you get a margin call. Brokers serving Mali traders often set stop out at 50%. Always keep margin level above 200% to avoid liquidation.
