How to Calculate Margin in Forex
What is Margin in Forex?
Margin is a deposit required by your broker to cover potential losses. It is not a fee but a portion of your trading capital set aside. For example, if you want to trade 10,000 units of EUR/USD with 1:50 leverage, the margin is 2% of the trade size, or $200 (assuming EUR/USD at 1.10). In San Marino, brokers often offer leverage from 1:10 to 1:500, but the local financial authority may cap it for retail clients.
Margin Calculation Formula
The basic formula is: Required Margin = (Trade Size in units) / (Leverage) x (Exchange Rate). For USD pairs, the exchange rate is 1. For example, a $10,000 trade on USD/JPY with 1:100 leverage requires $100 margin. For cross pairs like GBP/JPY, you must convert the base currency to USD.
Example for San Marino Traders
Assume you deposit $5,000 via Skrill to your broker account. You want to trade 1 standard lot (100,000 units) of EUR/USD at 1.10 with 1:50 leverage. Margin = 100,000 / 50 x 1.10 = $2,200. This means you need $2,200 as margin, leaving $2,800 as free margin. If the trade moves against you, your margin level (Equity / Used Margin x 100) must stay above the broker's threshold, typically 100%.
Types of Margin
Used Margin: Total margin locked in open positions. Free Margin: Available funds to open new trades. Margin Level: Percentage of equity to used margin. If it falls below 100%, you get a margin call. In San Marino, brokers regulated by the local financial authority must inform you before liquidation.
