1. What is Mutual Fund Expense Ratio?

The expense ratio is the annual fee that mutual funds charge their shareholders. It represents the percentage of the fund's assets that go towards covering operating expenses, management fees, administrative costs, and other fund expenses.

2. How Does the Calculator Work?

The calculator uses the expense ratio formula:

Where:

• \( ER \) — Expense Ratio (%)
• \( Expenses \) — Total annual fund expenses (USD)
• \( AUM \) — Assets Under Management (USD)

Explanation: The formula calculates what percentage of the fund's total assets is used to cover annual operating expenses.

3. Importance of Expense Ratio Calculation

Details: Expense ratio is a critical factor in mutual fund investing as it directly impacts investment returns. Lower expense ratios generally lead to higher net returns for investors over the long term.

4. Using the Calculator

Tips: Enter total annual expenses and assets under management in USD. Both values must be positive numbers. The calculator will compute the expense ratio as a percentage.
