1. What is the Expense Ratio Impact Formula?

The Expense Ratio Impact formula calculates the future value of an investment after accounting for annual expense ratio deductions over a specified number of years. It helps investors understand how fees impact long-term investment growth.

2. How Does the Calculator Work?

The calculator uses the Expense Ratio Impact formula:

Where:

• \( P \) — Principal investment amount ($)
• \( ER \) — Annual expense ratio (expressed as decimal)
• \( n \) — Number of years

Explanation: The formula calculates the compounding effect of annual expense ratio deductions on the principal investment over time.

3. Importance of Expense Ratio Calculation

Details: Understanding expense ratio impact is crucial for long-term investment planning. Even small differences in expense ratios can significantly affect final investment values over decades.

4. Using the Calculator

Tips: Enter principal amount in dollars, expense ratio as a decimal (e.g., 0.0015 for 0.15%), and number of years. All values must be valid (principal > 0, expense ratio between 0-1, years ≥ 1).

5. Frequently Asked Questions (FAQ)
