What Is Margin in Forex Trading? โ The Capital Behind Every Leveraged Trade
Margin is the amount of money your broker requires you to deposit as collateral to open and maintain a leveraged position. It is not a cost or a fee โ it is a security deposit that is returned to you when the trade is closed. Understanding margin is essential for every trader because running low on free margin is the most common cause of forced position closures and blown accounts.
The required margin formula is:
1 lot EUR/USD at 1.1000 with 1:100 leverage.
(100,000 ร 1 ร 1.1000) รท 100 = $1,100 required margin.
1 lot GBP/USD at 1.2700, 1:100 leverage, EUR account.
Margin in USD = $1,270. Convert at GBP/USD รท EUR/USD โ โฌ1,154.
This calculator handles the conversion automatically.
Required Margin by Leverage โ EUR/USD, 1 Standard Lot at 1.1000
The table below shows how dramatically required margin changes with leverage โ using EUR/USD as a reference. Higher leverage means less margin per trade but also less buffer before a margin call.
| Leverage | Margin % | Required Margin (1 lot) | Typical Account Type |
|---|---|---|---|
| 1:10 | 10% | $11,000 | Institutional / ultra-conservative |
| 1:30 | 3.33% | $3,667 | EU/UK regulated retail (ESMA cap) |
| 1:50 | 2% | $2,200 | US regulated retail (NFA/CFTC) |
| 1:100 | 1% | $1,100 | Standard offshore retail |
| 1:200 | 0.5% | $550 | High-leverage offshore broker |
| 1:500 | 0.2% | $220 | Maximum offshore leverage |

Frequently Asked Questions
How is forex margin calculated?
Required margin = (Contract Size ร Lots ร Price) รท Leverage. For example: 1 lot EUR/USD at 1.1000 with 1:100 leverage = (100,000 ร 1 ร 1.1000) รท 100 = $1,100. If your account is in EUR, the calculator converts the $1,100 into EUR at the live USD/EUR rate โ giving you the exact figure your broker will lock as margin.
What is the difference between margin and leverage?
Leverage is the multiplier your broker provides โ e.g. 1:100 means you control $100,000 with $1,000 of capital. Margin is the actual dollar amount required as collateral for that position. They are inversely related: higher leverage = lower margin requirement. A 1:100 leverage means a 1% margin rate.
How does the calculator handle non-USD account currencies?
Margin is first calculated in the instrument's quote currency (e.g. USD for EUR/USD). The calculator then fetches the live exchange rate between the quote currency and your account currency from TradingView and converts the result automatically. You can also enter the rate manually without waiting for the live fetch.
What happens if I don't have enough free margin?
If free margin falls to zero, you cannot open new trades. If your account equity drops below your broker's margin call level (typically 100% margin level), the broker issues a warning. If equity falls further to the stop-out level (typically 50%), the broker automatically closes your least profitable open position to protect the remaining balance.
Does margin change when I switch instruments?
Yes โ margin depends on the instrument's contract size and current price. Gold (XAU/USD) uses a 100-unit contract, Bitcoin uses 1 unit, and forex pairs use 100,000 units. This calculator automatically applies the correct contract size for all 76+ supported instruments.
