1. What is a Margin Calculator for Futures?

Definition: This calculator estimates the margin requirement for futures contracts based on contract size, price, and margin rate.

Purpose: It helps traders determine the capital required to open and maintain futures positions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M \) — Margin requirement (currency)
• \( S \) — Contract size (units)
• \( P \) — Price per unit (currency)
• \( R \) — Margin rate (percentage)

Explanation: The contract size multiplied by price gives the total contract value, which is then multiplied by the margin rate to determine the required deposit.

3. Importance of Margin Calculation

Details: Proper margin calculation ensures traders maintain sufficient funds to cover potential losses and meet exchange requirements.

4. Using the Calculator

Tips: Enter the contract size in units, price per unit in currency, and margin rate as a percentage (default 10%). All values must be > 0.
