1. What Is Expense Ratio?

The Expense Ratio is a measure of a mutual fund's operating expenses expressed as a percentage of its average assets under management (AUM). It represents the annual cost investors pay for fund management and administration.

2. How Does the Calculator Work?

\[ \text{Expense Ratio} = \frac{\text{Total Expenses}}{\text{Average AUM}} \times 100\% \]

Where:

\( \text{Total Expenses} \) — Annual operating costs of the fund (USD)
