How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or a cost; it is a security deposit required by your broker to cover potential losses. It is expressed as a percentage of the full trade value. For example, with 1:100 leverage, you only need 1% of the trade value as margin. For Fiji traders, margin is calculated in USD, regardless of your base currency.
The Margin Formula
The standard formula is: Margin = (Lot Size × Contract Size × Market Price) ÷ Leverage. Lot size refers to the number of lots (standard = 100,000 units, mini = 10,000, micro = 1,000). Contract size is usually 100,000 for standard lots. Market price is the current price of the currency pair. Leverage is the ratio provided by your broker.
Example for Fiji Traders
Suppose you are a Fiji trader and you want to buy 1 standard lot of EUR/USD at a market price of 1.1000 with 1:100 leverage. Your margin calculation: (1 × 100,000 × 1.1000) ÷ 100 = $1,100 USD. If you deposit $5,000 via Skrill, your used margin is $1,100, and your free margin is $3,900. This free margin acts as a buffer against losses.
How Leverage Affects Margin
Higher leverage reduces margin requirements. For the same trade with 1:500 leverage, margin is only $220 USD. However, higher leverage also increases risk. Local financial authority may limit maximum leverage to 1:200 for retail Fiji traders to protect against excessive losses. Always check your broker's leverage options.
Margin Call and Stop Out
If your account equity falls below the required margin, you receive a margin call. For example, if your equity drops to $1,100 (the used margin), the broker may close positions. Fiji traders using Bank Transfer should maintain extra funds to avoid liquidation, as bank transfers take time. USDT and Skrill deposits are faster for emergency top-ups.
