What Is an Expense Ratio Calculator?
An expense ratio calculator helps you understand the true cost of investing in a mutual fund or ETF. The expense ratio is the annual fee charged by the fund to cover management, administrative, and operating costs. It's expressed as a percentage of your investment and is deducted from the fund's returns before they reach your account.
Even a seemingly small expense ratio , like 0.75% , can have a massive impact on your investment returns over time due to the power of compound interest. This calculator shows you exactly how much you're paying in fees and how much more you could earn with a lower-cost fund.
How Does the Expense Ratio Calculator Work?
The calculator uses two future value formulas to compare your investment growth with and without fees:
- Without Fees: Your investment grows at the full expected return rate.
- With Fees: Your investment grows at the expected return rate minus the expense ratio (e.g., 8% − 0.75% = 7.25%).
- The calculator compounds both the initial lump sum and any monthly contributions over the specified time period.
- The Total Cost of Fees is the difference between the two final values.
