Frequently Asked Questions

Everything you need to know.

What is a good expense ratio for a mutual fund?
Index funds: 0.03–0.20% is excellent. Actively managed funds: 0.5–1.5% is common, but research shows most active managers underperform their benchmark after fees. Target-date retirement funds: 0.10–0.75%. Avoid anything above 1% unless you have a specific reason.
Are advisor fees worth paying?
A fiduciary advisor charging 1% AUM may add value through tax optimization, behavioral coaching, and estate planning — studies suggest good advisors add 1.5–3% in net returns annually. A non-fiduciary broker recommending high-fee products is almost never worth the cost.
