1. What is Expense Ratio For Mutual Funds Formula?

The Expense Ratio for Mutual Funds Formula calculates the percentage of a fund's assets used for administrative, management, advertising, and other operating expenses. It represents the annual cost of owning a mutual fund as a percentage of your investment.

2. How Does the Calculator Work?

The calculator uses the Expense Ratio formula:

\[ ER = \frac{\text{Total Expenses}}{\text{Average AUM}} \times 100 \]

Where:

$ ER $ — Expense Ratio (%)
$ \text{Total Expenses} $ — Total annual operating expenses (USD)
$ \text{Average AUM} $ — Average Assets Under Management (USD)

Explanation: The formula measures how efficiently a mutual fund is managed by comparing total expenses to the fund's average assets. A lower expense ratio generally indicates better cost efficiency.
