1. What Is Expense Ratio?

Expense ratio represents the percentage of a fund's assets that are used for administrative, management, advertising, and all other expenses. It is a key metric for investors to evaluate the cost efficiency of mutual funds, ETFs, and other investment vehicles.

2. How Does The Calculator Work?

The calculator uses the expense ratio formula:

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

Where:

\( \text{Total Expenses} \) — All annual operating expenses in USD
\( \text{Average AUM} \) — Average Assets Under Management in USD
\( 100\% \) — Conversion to percentage format

Explanation: The formula calculates what percentage of the fund's assets are consumed by expenses annually, providing investors with a standardized way to compare costs across different funds.
