How Margin Is Calculated
Required Margin = (Lots × Contract Size × Price) ÷ Leverage
For 1 standard lot of EUR/USD at 1.1000 with 1:100 leverage: (1 × 100,000 × 1.1000) ÷ 100 = $1,100 required margin.
Margin level = (Equity ÷ Used Margin) × 100%. A margin level below 100% triggers a margin call. Experienced traders aim to keep margin level above 500% by not over-leveraging their accounts.
Free margin = Equity − Used Margin. This is the capital available to open additional positions or absorb losses without triggering a margin call.
