How to Calculate Margin in Forex
What is Margin in Forex?
Margin is the collateral required by a broker to open and maintain a leveraged position. It is not a fee but a deposit. For Kiribati traders, margin is always calculated in USD, the base currency for most local accounts.
The Basic Formula
The standard formula is: Margin = (Trade Size / Leverage) × Exchange Rate. Trade size is in units (e.g., 100,000 for 1 lot), leverage is the ratio (e.g., 100:1), and the exchange rate converts the base currency to your account currency (USD).
Step-by-Step Example for Kiribati
Assume you want to buy 1 lot of USD/JPY (100,000 units) with 1:100 leverage. Since USD is the quote currency, the exchange rate is 1. Margin = (100,000 / 100) × 1 = $1,000 USD. If you trade EUR/USD (where EUR is base), you need to convert: Margin = (100,000 / 100) × 1.10 (if EUR/USD is 1.10) = $1,100 USD.
Understanding Leverage and Used Margin
Leverage multiplies your buying power. For Kiribati traders, higher leverage means lower margin requirements but higher risk. Used margin is the total margin for all open positions. Free margin is the difference between equity and used margin, which determines if you can open new trades.
Margin Level and Margin Call
Margin level = (Equity / Used Margin) × 100%. If it falls below 100%, you get a margin call. In Kiribati, brokers typically set the stop-out level at 50-100%. Always monitor your margin level to avoid forced closures.
