The U.S. Securities and Exchange Commission's Calculator lets you compare the costs of mutual funds and run what-if scenarios. Variables used are the amount invested, average annual return, how long the fund is held and sales or redemption fees. Check it out at www.sec.gov.
This site also has loads of data on US mutual funds. However, you may find it easier to receive the same information faster on EDGAR Online (www.edgar-online.com) or FreeEDGAR (www.freeedgar.com). EDGAR is an acronym for Electronic Data Gathering Analysis and Retrieval System. Want to compare the monthly cost of most business accounts?
