1. What Is An Expense Ratio?

The Expense Ratio represents the annual fund fees as a percentage of the fund's average net assets. It measures the percentage of fund assets used for administrative, management, advertising, and other operating expenses.

2. How Does The Calculator Work?

The calculator uses the Expense Ratio formula:

\[ \text{Expense Ratio} = \left( \frac{\text{Operating Expenses}}{\text{Average Net Assets}} \right) \times 100 \]

Where:

$ \text{Operating Expenses} $ — Total annual operating costs of the fund ($)
$ \text{Average Net Assets} $ — Average value of the fund's net assets over the period ($)
$ 100 $ — Conversion factor to express result as percentage

Explanation: The formula calculates what percentage of the fund's assets are consumed by operating expenses each year, providing investors with a clear measure of cost efficiency.

Details: Expense ratios are crucial for investors to compare fund costs, understand the impact of fees on returns, and make informed investment decisions. Lower expense ratios generally lead to higher net returns for investors.
