1. What is a Future And Option Margin Calculator?

Definition: This calculator estimates the margin required for futures and options trading based on lot size, price per unit, and margin rate.

Purpose: It helps traders determine the capital required to enter derivative positions and manage risk effectively.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Margin} \) — Required margin amount (in currency)
• \( \text{Lot Size} \) — Number of units in the contract
• \( \text{Price} \) — Price per unit (in currency)
• \( \text{Margin Rate} \) — Percentage of total value required as margin

Explanation: The calculator multiplies the contract size by the current price to get total value, then applies the margin percentage.

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 lot size, current price per unit, and margin rate percentage (default 5%). All values must be > 0.
