1. What is Variation Margin Interest?

Variation Margin Interest refers to the interest calculated on the variation margin in futures trading. Variation margin represents the daily settlement of gains and losses on futures contracts, and interest is applied to these margin amounts based on prevailing daily rates.

2. How Does the Calculator Work?

The calculator uses the variation margin interest formula:

Where:

• \( Variation\ Margin \) — Daily settlement amount in currency
• \( Daily\ Rate \) — Daily interest rate expressed as a decimal
• \( Interest \) — Calculated interest amount in currency

Explanation: The formula calculates the interest charge or credit on the daily variation margin amount based on the specified daily interest rate.

3. Importance of Variation Margin Interest Calculation

Details: Accurate calculation of variation margin interest is crucial for proper accounting of futures trading positions, managing cash flow requirements, and understanding the true cost or benefit of maintaining futures positions.

4. Using the Calculator

Tips: Enter variation margin in currency units and daily rate as a decimal (e.g., 0.05 for 5%). Both values must be positive numbers.
