Margin calculator
See how much margin a leveraged position ties up, and how large the position really is, before you open it.
How it works
Position value = lots × contract size × price. Required margin = position value ÷ leverage. At 30:1, margin is 1/30 of the position, or about 3.33%.
Example, with hypothetical numbers: one standard lot of EUR/USD at 1.1000 is a position worth 110,000 US dollars. At 30:1 it needs 110,000 ÷ 30 = 3,666.67 dollars of margin.
Margin is a deposit, not a cost, but it is also what you can lose quickly: a move of 3.33% against a 30:1 position wipes out the margin. Regulators cap the leverage brokers can offer retail clients in many countries; our guide to leverage limits and negative balance protection explains the rules. If your account falls below the broker's margin requirement, positions can be closed automatically.
The calculation runs in your browser and nothing you type is sent anywhere. Results are arithmetic, not advice: your broker's own figures, contract specifications and charges always apply. Trading leveraged products carries a high risk of losing money.
