How to use

Mutual funds and ETFs charge an expense ratio annually. Over a long horizon even 0.75% shaves a meaningful chunk off your balance.

Formula

Loss = P·(1+r)n − P·(1+r−f)n

FAQ

Index funds vs active?

Index funds often charge 0.05–0.20%; active funds can exceed 1%, a large gap over time.

Is a higher return worth a higher fee?

Usually not — most active funds fail to beat their index after fees.
