Margin calculator
Know how much margin a position locks before you open it — at any leverage. Margin is the collateral your broker sets aside to keep a leveraged position open. Higher leverage means less margin per lot — and less free margin buffer.
Account currency: USD · standard MetaTrader contract sizes. Estimates for guidance only — actual values depend on the instrument specification and your account type in MT4/MT5.
How it works
- Margin = notional position value ÷ leverage.
- Notional value = contract size × price × lots (for USD-based pairs like USDJPY it is simply contract size × lots).
- Example contract sizes: 100,000 for FX pairs, 100 oz for gold.
Frequently asked questions
What is margin in forex?
Margin is the deposit required to open and hold a leveraged position. It is not a fee — it is locked while the position is open and released when it closes.
How does leverage change the margin?
Margin is inversely proportional to leverage: at 1:100 a $100,000 position needs $1,000; at 1:500 it needs only $200. Higher leverage frees margin but magnifies both profits and losses.
What leverage does TNFX offer?
