1. What is Net Return?

Net Return represents the actual return an investor receives after accounting for all fees and expenses, specifically the expense ratio in index fund investments. It shows the true performance of your investment after costs.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Gross Return} \) — The total return before fees and expenses (%)
• \( \text{Expense Ratio} \) — The annual fee charged by the fund (%)
• \( \text{Net Return} \) — The actual return received by the investor (%)

Explanation: This calculation helps investors understand how much of their investment return is consumed by fund management fees.

3. Importance of Expense Ratio

Details: Expense ratios significantly impact long-term investment returns. Even small differences in expense ratios can compound into substantial differences in final portfolio value over decades of investing.

4. Using the Calculator

Tips: Enter gross return and expense ratio as percentages. Both values must be non-negative numbers. The calculator will instantly show your net return after fees.
