FAQ
How does an expense ratio affect returns over time?
Enter a portfolio value, a return assumption, an expense ratio, and a horizon. The result compares the same scenario with and without the fee, so you can see the compounded cost of the expense ratio.
Is a lower expense ratio always better?
Lower fees leave more of the return with you, all else equal — but funds differ in what they hold. This tool isolates the fee effect on a single set of assumptions you enter.
Does this predict fund performance?
No. It only shows how a fee assumption changes an illustrative scenario; it is not a forecast.
