How to Calculate Margin - Step by Step
We calculate required margin using this formula: Required Margin = (Position Size × Current Price) ÷ Leverage. For cross-currency pairs, we automatically convert to your account currency using real-time exchange rates.
Quick Example:
Trading 1.0 lot of EUR/USD at 1.0900 with 1:100 leverage:
Position Value = 100,000 × 1.0900 = $109,000
Required Margin = $109,000 ÷ 100 = $1,090
Understanding Margin Levels
Safe Zone (>200%)
Comfortable trading with room for drawdown
Warning Zone (100-200%)
Monitor closely, consider reducing exposure
Danger Zone (<100%)
Cannot open new trades, stop-out risk

Margin Management Tips
Maintain Buffer Margin
Keep at least 50-100% free margin as buffer. This prevents margin calls during normal market volatility and allows for new opportunities.
Size Positions by Risk First
Calculate position size based on acceptable risk, then verify margin requirements. Never max out available margin.
Monitor Correlated Exposure
Multiple positions in correlated pairs increase overall margin usage and risk. Diversify to manage margin efficiently.
Understand Leverage Impact
Higher leverage means lower margin but higher risk. Use leverage appropriate to your experience and risk tolerance.
Watch During Volatility
Market volatility can quickly change margin levels. Monitor more frequently during news events and volatile sessions.
Plan for Overnight Holds
Positions held overnight may face gap risk. Ensure adequate margin to handle potential adverse gaps at market open.
Frequently Asked Questions
What is required margin vs free margin?
Required margin is the collateral locked for open positions. Free margin is what remains available for new trades after subtracting required margin from equity.
How does leverage affect margin requirements?
Higher leverage reduces required margin per trade. For example, 1:100 leverage needs 1% of position value as margin, while 1:500 needs only 0.2%.
What is margin level and why does it matter?
Margin level = (Equity / Required Margin) × 100. Below 100% means you cannot open new trades. Below 50% typically triggers stop-out (forced position closure).
Why did my margin requirement suddenly increase?
Margin requirements can change due to floating P&L affecting equity, currency conversion rate changes, or broker adjusting leverage during volatile periods.
How do I calculate margin for cross-currency pairs?
For cross pairs, convert the base currency to your account currency using current exchange rates. Our calculator handles this conversion automatically.
What happens during a margin call?
A margin call warns you when margin level drops below a threshold (usually 100%). You must add funds or close positions to avoid stop-out.
Can I trade without margin?
No, forex trading requires margin as collateral. The amount depends on leverage and position size. Even with high leverage, some margin is always required.
How much margin should I keep free?
Keep at least 50-100% free margin as a buffer. This prevents margin calls during normal market fluctuations and allows for new opportunities.
