A breakpoint generally refers to a level of investment at which the fee structure changes. For mutual funds, it can mean a level that triggers a reduced sales load.

An investor can either hit the breakpoint at the time of original investment or in some cases can sign a letter of intent to reach a certain investment level and qualify for the reduced fee that way.

There may be multiple breakpoints for an investment, with the fee falling at each one.
