How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or cost; it's a security deposit held by your broker. It allows you to control larger positions with a smaller amount of capital. For example, with 1:100 leverage, you can control 100,000 units of currency with just 1,000 units of margin.
Margin Calculation Formula
The basic formula is: Required Margin = (Trade Size in Units) / Leverage. Trade size is typically measured in lots: 1 standard lot = 100,000 units, 1 mini lot = 10,000 units, 1 micro lot = 1,000 units. For example, if you want to trade 1 mini lot of EUR/USD with 1:100 leverage: Required Margin = 10,000 / 100 = 100 USD.
Converting to KES
Since your trading account may be denominated in KES, convert the margin using the current exchange rate. If 1 USD = 130 KES, then 100 USD = 13,000 KES. This is the amount you need to deposit via M-Pesa or Bank Transfer.
Example with USD/JPY
Suppose you trade 1 standard lot of USD/JPY at 1:50 leverage. Trade size = 100,000 units. Required Margin = 100,000 / 50 = 2,000 USD. In KES: 2,000 x 130 = 260,000 KES. Always check your broker's margin requirements, as they vary by currency pair and leverage.
Margin Level and Margin Call
Margin level = (Equity / Used Margin) x 100%. If it falls below the broker's threshold (e.g., 100%), you get a margin call. In Kenya, use mobile trading apps to monitor your margin level in real-time. Add funds quickly via M-Pesa to avoid liquidation.
