How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a cost or fee—it is a security deposit that your broker holds to cover potential losses. In Armenia, margin is typically denominated in USD, the most common account currency. The formula for calculating margin is: Margin = (Lot Size × Contract Size × Current Price) ÷ Leverage.
Example Calculation for Armenia Traders
Suppose you want to trade 1 standard lot (100,000 units) of EUR/USD at a current price of 1.1000, with leverage of 1:30 (the maximum allowed by the local financial authority for retail traders). The calculation is:
Margin = (1 × 100,000 × 1.1000) ÷ 30 = 110,000 ÷ 30 = 3,666.67 USD.
This means you need at least 3,666.67 USD in your account to open this trade. If you use leverage of 1:100 (available from some brokers), margin drops to 1,100 USD.
How Leverage Affects Margin
Higher leverage reduces margin but increases risk. For Armenia traders, the local financial authority limits leverage to 1:30 for major pairs and 1:20 for minors and gold. Some offshore brokers may offer 1:500 or higher, but this is not recommended due to high risk and lack of local protection. Always calculate margin before entering a trade using the broker's margin calculator or the formula above.
Margin Level and Margin Call
Margin level = (Equity ÷ Used Margin) × 100%. If it falls below 100%, your broker may issue a margin call. In Armenia, brokers registered with the local financial authority must notify you clearly. To avoid this, maintain a healthy margin level above 200% and use stop-loss orders.
