Loads vary in costs - at the high end you might see a 8.5% load. Even 1% is significant. Be sure to read "Say No to Loaded Funds."
Loads typically come in three varieties and the funds are typically noted as "Class A," "Class B," and "Class C." The first is a front-end load, where the fee is paid up front (when you buy the fund), the second is a back-end load (you pay on your way out of the fund) and the third is a constant load where you are charged each year.
