How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or transaction cost. It is a portion of your account equity set aside to maintain open positions. For example, with 1:100 leverage, you only need 1% of the trade value as margin. The broker holds this amount until you close the trade.
The Margin Formula
The basic formula is: Margin = (Trade Size in Lots * Contract Size) / Leverage. For a standard lot (100,000 units) with 1:100 leverage, margin = 100,000 / 100 = 1,000 of the base currency. If trading EUR/USD, that's 1,000 EUR. Convert to USD then PHP for local context.
Example for Philippines Traders
Suppose you want to trade 0.5 lots of GBP/JPY with 1:200 leverage. Contract size = 100,000. Margin in GBP = (0.5 * 100,000) / 200 = 250 GBP. If GBP/USD = 1.25, that's 312.50 USD. At 1 USD = 58 PHP, margin = ₱18,125. You can deposit this via GCash or PayMaya.
Margin in USDT Trading
Many Philippines traders use USDT-based brokers. For a 0.1 lot trade with 1:100 leverage, margin = (0.1 * 100,000) / 100 = 100 USDT. This is simple since USDT is pegged to USD. Always check the broker's margin call level (e.g., 100% margin level) to avoid liquidation.
