Calculate how much margin (free capital) you need in your account to open a position at a given leverage level.
What is margin in forex?
Margin is the amount of money your broker requires you to have in your account to open and maintain a leveraged position. It is not a cost — it is a deposit that is returned to your account when the position is closed. The margin requirement depends on your leverage and the size of your position.
How to calculate margin
The margin formula is:
For example, 1 standard lot of EUR/USD at 1.0850 with 1:100 leverage: Margin = (1 × 100,000 × 1.0850) / 100 = $1,085. With 1:500 leverage, the same position requires only $217.
Leverage comparison table
| Leverage | Margin for 1 Lot EUR/USD |
|---|---|
| 1:50 | $2170.00 |
| 1:100 | $1085.00 |
| 1:200 | $542.50 |
| 1:300 | $361.67 |
| 1:500 | $217.00 |
Margin values are approximate. Actual margin requirements may vary based on your broker's specifications and account type. Higher leverage increases both potential profits and losses.
