계약 정보를 입력하고 계산하세요

⚠️ Leveraged trading involves significant risk of loss. Actual margin requirements vary by exchange and broker.

📖How to Use the Margin Calculator

1Enter Contract Details

Select instrument type, enter the underlying asset price, contract multiplier, and number of contracts. For S&P 500 E-mini futures, the multiplier is $50.

2Enter Margin Rate

Input your broker's initial margin rate. This varies by instrument and broker — typically 5-15% for equity futures.

3Understand Liquidation Price

The theoretical liquidation price is where your margin is fully depleted. In practice, a margin call occurs before this point (at the maintenance margin level).

💡Use Cases

Verify margin required before opening futures positions
Understand leverage exposure and risk
Pre-calculate liquidation price for stop-loss planning

Frequently Asked Questions

What is the difference between initial and maintenance margin?

Initial margin is what you need to open a position. Maintenance margin is the minimum to keep it open. A margin call occurs when your account falls below the maintenance level.

What does 10x leverage mean?

It means you control $10,000 in assets with $1,000 in margin. Profits and losses are both multiplied by 10x.
