MarketRiders features an interesting online mutual fund cost calculator. It allows you to input sever ticker symbols as well as the amount invested. The program then returns the yearly loss from mutual fund fees, which is a sobering number if you look at it over 20 years.
You are then prompted to input your email address for a detailed report on hidden mutual fund fees, the impact on your retirement over time and an alternative lower cost ETF portfolio.
The last feature is probably the most important one if you are currently considering converting some of your mutual funds into equivalent ETFs. Check it out and see if you find it useful.
