How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or a cost – it is a security deposit held by your broker while a trade is open. In Bosnia and Herzegovina, brokers typically require margin in USD, and it is calculated based on the position size and leverage you choose.
The Margin Formula
The basic formula is: Required Margin = (Lot Size × Contract Size × Market Price) / Leverage. For example, if you trade 1 standard lot (100,000 units) of EUR/USD at 1.1000 with 1:100 leverage, the margin is (1 × 100,000 × 1.1000) / 100 = 1,100 USD.
How Leverage Affects Margin
Higher leverage reduces the margin required. With 1:30 leverage (common for EU-regulated brokers available in Bosnia and Herzegovina), the same trade would require (1 × 100,000 × 1.1000) / 30 = 3,666.67 USD. With 1:500 leverage (offered by offshore brokers), it would be only 220 USD. Lower margin means higher risk.
Example for Bosnia and Herzegovina Traders
Suppose you have a 5,000 USD account and want to trade USD/CHF at 0.9200. You use 1:100 leverage and buy 0.5 lots (50,000 units). Margin = (0.5 × 100,000 × 0.9200) / 100 = 460 USD. Your used margin is 460 USD, and free margin is 4,540 USD.
