Mutual Fund Fees
A better way to calculate what the average investor is paying in fees is to use the dollar-weighted average fee. According to Lipper, calculated this way, the average fee is .936%. That's quite difference! Why is there so much difference? It is because most of the investors and most of the money is invested in the bigger mutual funds which typically have lower costs.
So, the next time you are sitting with your broker and he or she tells you "this mutual fund has a below average expense of 1.25%..." you can correct them.
