1. What is the Expense Ratio?

The Expense Ratio (ER) is a measure of what it costs an investment company to operate a mutual fund or ETF. It's expressed as a percentage of assets and includes management fees, administrative costs, and other operational expenses.

2. How Does the Calculator Work?

The calculator uses the Expense Ratio formula:

Where:

• \( Operating\ Expenses \) — Total annual operating costs of the fund
• \( Assets \) — Average assets under management for the fund

Explanation: The ratio shows what percentage of assets is consumed by operating expenses each year.

3. Importance of Expense Ratio

Details: A lower expense ratio means more of the fund's assets are being used to invest in securities rather than pay for expenses. Even small differences in expense ratios can significantly impact investment returns over time.

4. Using the Calculator

Tips: Enter operating expenses and assets in dollars. Both values must be positive numbers. The result shows the expense ratio as a percentage.
