A front-end load is a percentage of what you hand over, not of what gets invested. A fund quoting a 5% front-end load removes 5% of your payment and invests the remaining 95%. That framing matters because recovering your original outlay then requires the smaller invested balance to grow by more than the load percentage. The gap is modest at small loads and grows at the higher levels loads have historically reached. It is not a criticism of the charge, just a property of taking a slice off the top, and it is invisible to anyone who thinks of the load as a fee added on rather than an amount removed.
Breakpoints reduce the load at larger amounts, and rights of accumulation help you reach them. Funds that charge a front-end load commonly offer discounts at stated investment levels, called breakpoints, so a larger purchase can carry a lower load percentage. Two features extend those discounts: rights of accumulation let the value of what you already hold in the fund family count toward a breakpoint, and a letter of intent lets you commit to reaching a breakpoint over a period (often 13 months) and get the lower rate now. Failing to claim a breakpoint you qualify for is a known and avoidable overcharge, which is why the amount and the eligibility are worth checking in the prospectus before buying.
It is one-time, which is the whole contrast with the expense ratio. A front-end load is surrendered once, at purchase, so spread across a long holding period its drag on the annual return falls. The expense ratio is charged on the balance every year, so its total effect rises the longer you hold. A load fund with a low expense ratio and a no-load fund with a higher one can therefore trade places depending on how many years the money stays invested. Comparing two funds on the load alone, or on the expense ratio alone, answers only half the question.
Where the money goes is a plain fact. A front-end load compensates the broker or intermediary who sold the fund. It does not pay the portfolio manager and does not accrue to the fund, which is why the same portfolio is often available in a no-load share class to an investor buying without an intermediary. The charge relates to how the fund was bought, not to what it does.
