How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a cost but a security deposit held by your broker to cover potential losses. In Afghanistan, margin is always quoted in USD when using a USD-denominated account. For instance, if you open a trade worth $10,000 with 1:200 leverage, your required margin is $50 ($10,000 ÷ 200).
Margin Formula
The standard formula is: Required Margin = (Trade Size × Contract Size × Market Price) ÷ Leverage. Trade size is in lots (standard lot = 100,000 units), contract size is 100,000 for most pairs, market price is the current exchange rate, and leverage is your broker's offer (e.g., 1:100, 1:200).
Example for Afghanistan Traders
Assume you trade 0.1 lot (10,000 units) of USD/JPY at 150.00 with 1:100 leverage. Required margin = (0.1 × 100,000 × 150.00) ÷ 100 = $1,500. If your account is in USD, you need $1,500 available as margin. Always use a margin calculator or check your broker's platform for exact numbers.
Margin Level and Margin Call
Margin level = (Equity ÷ Used Margin) × 100%. If it falls below the broker's threshold (e.g., 80%), you get a margin call. In Afghanistan, brokers may require additional funds via Bank Transfer or USDT within 24 hours. If ignored, your trades are automatically closed at a loss.
