A number of load and no-load mutual funds levy 12b-1 fees on the value of your mutual fund account to offset the fund's promotional and marketing expenses.

These asset-based fees, which get their name from the Securities and Exchange Commission (SEC) ruling that describes them, typically amount to somewhere between 0.5% and 1% annually of the net assets in the fund.

A fund that charges 12b-1 fees must detail those expenses, along with other fees it imposes, in its prospectus.
