What are mutual fund share classes and loads, and why do they matter?

Share classes are different versions of the same mutual fund that charge fees in different ways — and they can quietly cost you thousands. A "load" is a sales commission. Class A shares typically charge a front-end load (you pay, say, 5.75% off the top before a dollar gets invested). Class B and C shares may charge a back-end load when you sell or higher ongoing annual fees instead. These commissions usually pay a salesperson, not better performance. There's almost never a reason for a do-it-yourself investor to pay a load, because no-load index funds deliver the same or better results for free. If someone steers you to a loaded fund, ask why a no-load version won't do. Always check the prospectus for the share class and load before buying.
