1. What is Expense Ratio Cost?

Expense Ratio Cost represents the annual fees paid for investment fund management, calculated as a percentage of assets under management. It covers operational expenses, management fees, and other fund administration costs.

2. How Does the Calculator Work?

The calculator uses the Expense Ratio Cost formula:

Where:

• \( \text{AUM} \) — Assets Under Management in USD
• \( \text{ER} \) — Expense Ratio expressed as a percentage

Explanation: The expense ratio is converted from percentage to decimal form before multiplication with AUM to calculate the actual dollar cost.

3. Importance of Expense Ratio Cost Calculation

Details: Understanding expense ratio costs is crucial for investment decision-making, as high fees can significantly impact long-term investment returns through compounding effects over time.

4. Using the Calculator

Tips: Enter Assets Under Management in USD and Expense Ratio as a percentage. Both values must be positive numbers (AUM > 0, ER ≥ 0).

5. Frequently Asked Questions (FAQ)
