Be sure to review carefully the fee tables of any funds you're considering, including no-load funds. Even small differences in fees can translate into large differences in returns over time. For example, if you invested $10,000 in a fund that produced a 10% annual return before expenses and had annual operating expenses of 1.5%, then after 20 years you would have roughly $49,725. But if the fund had expenses of only 0.5%, then you would end up with $60,858 — an 18% difference. 

A mutual fund cost calculator can help you understand the impact that many types of fees and expenses can have over time. It takes only minutes to compare the costs of different mutual funds. 

Classes of Funds 

Many mutual funds offer more than one class of shares. For example, you may have seen a fund that offers "Class A" and "Class B" shares. Each class will invest in the same "pool" (or investment portfolio) of securities and will have the same investment objectives and policies. But each class will have different shareholder services and/or distribution arrangements with different fees and expenses. As a result, each class will likely have different performance results.  A multi-class structure offers investors the ability to select a fee and expense structure that is most appropriate for their investment goals (including the time that they expect to remain invested in the fund). Here are some key characteristics of the most common mutual fund share classes offered to individual investors: 

• Class A Shares— Class A shares typically impose a front-end sales load. They also tend to have a lower 12b-1 fee and lower annual expenses than other mutual fund share classes. Be aware that some mutual funds reduce the front-end load as the size of your investment increases. If you're considering Class A shares, be sure to inquire about breakpoints.
     
• Class B Shares— Class B shares typically do not have a front-end sales load. Instead, they may impose a contingent deferred sales load and a 12b-1 fee (along with other annual expenses). Class B shares also might convert automatically to a class with a lower 12b-1 fee if the investor holds the shares long enough.
     
• Class C Shares — Class C shares might have a 12b-1 fee, other annual expenses, and either a front- or back-end sales load. But the front- or back-end load for Class C shares tends to be lower than for Class A or Class B shares, respectively. Unlike Class B shares, Class C shares generally do not convert to another class. Class C shares tend to have higher annual expenses than either Class A or Class B shares.  

Tax Consequences 

When you buy and hold an individual stock or bond, you must pay income tax each year on the dividends or interest you receive. But you won't have to pay any capital gains tax until you actually sell and unless you make a profit.
