How to Calculate Margin in Forex
Understanding the Margin Formula
Margin = (Lot Size × Contract Size × Market Price) / Leverage. The contract size for standard lot is 100,000 units, mini lot is 10,000, and micro lot is 1,000. Leverage amplifies your buying power—common leverage in Egypt is 1:100 or 1:200, but EFSA may cap it for retail clients.
Step-by-Step Example for Egypt Traders
Suppose you want to buy 1 mini lot (10,000 units) of USD/EGP. The current exchange rate is 30.50 EGP per USD. Your broker offers 1:100 leverage. Margin = (10,000 × 30.50) / 100 = 3,050 EGP. This means you need 3,050 EGP in your account to open this trade.
Margin in EGP vs USD
If your account is denominated in EGP, the calculation is straightforward. If it's in USD, you must convert the margin to EGP using the current exchange rate. For example, a margin of 100 USD equals 3,050 EGP at 30.50 rate. Always check your broker's conversion policy.
How Leverage Affects Margin
Higher leverage reduces margin requirement but increases risk. At 1:50 leverage, margin for the same trade would be (10,000 × 30.50) / 50 = 6,100 EGP. At 1:200, it's only 1,525 EGP. Egypt traders should use lower leverage to avoid margin calls during EGP volatility.
Margin Call and Stop Out Levels
When your account equity falls below the margin requirement, you get a margin call. Brokers in Egypt typically set margin call at 100% and stop out at 50%. For example, if your used margin is 3,050 EGP, a margin call triggers when equity drops to 3,050 EGP. Always monitor your free margin.
