Mutual fund fees 101: Expense ratios, sales loads, 12b-1 fees and returns

Because mutual fund fees can directly affect your investment returns, it’s critical to know what and how much you’re paying, as well as how each fee works. Some costs are charged every year through the fund itself, while others may apply only when you buy, sell or move shares. The key point is simple, though: The more you pay in fees and expenses, the less money you have invested and in returns.

While mutual funds with higher costs aren’t automatically a bad choice, investors should understand how expense ratios, sales charges (also called sales loads), 12b-1 fees and other mutual fund fees are disclosed – and how they might affect returns. Investors should also know how to compare one fund’s fees against another’s before investing.

The basics of mutual fund fees

Mutual fund fees generally fall into two buckets: shareholder fees and ongoing operating expenses. Shareholder fees may include the following:

In addition, annual fund operating expenses may include the following:

All these costs – which are typically presented in a standardized prospectus fee table – matter. After all, they can lower the value of what you keep. When fees are paid directly from fund assets, the fund’s overall value decreases. In turn, the value of investors’ shares decreases, as well. Even small differences in fees can compound, resulting in significant differences in returns over time.

For example, a higher-cost mutual fund must outperform a lower-cost fund just to deliver the same result to you after expenses. This is why fee analysis isn’t just a fine-print exercise; it’s part of evaluating whether a mutual fund is worth owning in the first place.

Expense ratios: An ongoing cost

The total annual operating expenses are typically shown as a percentage of a mutual fund’s average net assets, otherwise known as the expense ratio. This ratio accounts for management fees, 12b-1 fees and other administrative expenses. The expense ratio is often the easiest figure to review when comparing mutual fund fees because it captures recurring expenses in a single number.

Expense ratios can vary by strategy, however. Index funds generally require minimal day-to-day management, so the cost to invest in them may be lower than the cost to invest in an actively managed fund. This doesn’t mean every low-cost fund is necessarily better, but it does make expense ratios a useful gauge for comparing similar products.

You can find the expense ratio in the prospectus, on the fund’s website or in financial publications. You can also use the Financial Industry Regulatory Authority’s (FINRA) online Fund AnalyzerOpens overlay to compare the effect of fund expenses over time.

Sales loads: Front-end and back-end fees

A sales load is a charge associated with buying or selling mutual fund shares, and the type of sales load or sales charge depends on share class and structure. There are four mutual fund share classes – A, B, C and institutional – and the levels indicate restrictions on voting rights or investment minimums required for ownership.

A front-end sales load is charged when you buy shares, reducing the amount of money available to invest right away. For example, a $5,000 purchase with a 5% front-end charge leaves $4,750 invested after the $250 sales charge is deducted.

A back-end, or deferred, sales charge applies when you redeem or sell shares. This is often based on the lesser of the value of the initial investment or the value at redemption. This is why reading the fund’s prospectus matters: Fee structures and schedules can vary from fund to fund.

No-load funds do not charge sales loads, which is one reason they can be attractive to cost-conscious investors. But “no load” doesn’t necessarily mean “no cost.” A fund may still have an expense ratio and other charges as described earlier, so investors should always review the fee table rather than relying on a fund’s label alone.

Mutual fund class A shares typically charge a front-end sales load. Class B shares typically do not charge a front-end load, but may charge a contingent deferred sales charge (CDSC) when you sell your shares within a certain period (typically six years). And class C shares typically have a level-load fee structure where you do not pay a front-end sales charge, but may pay a back-end load when you sell your shares in a short period of time, like one year, and they may also charge higher 12b-1 fees.

12b-1 fees: Marketing and distribution charges

Often known as distribution or service fees, 12b-1 fees are ongoing charges paid out of fund assets to cover distribution costs and, in some cases, shareholder service fees. They typically apply to mutual funds rather than exchange-traded funds (ETFs). These fees may be used for:

Investors may not always see 12b-1 fees as a separate line item since they’re often built into the fund’s expense ratio.

Other fees and hidden costs

It’s important to note that not every fee shows up in a fund’s expense ratio. In fact, depending on an investor’s actions, mutual funds may also charge account fees, redemption fees, exchange fees and purchase fees. Note, too, that the fee table in the fund’s prospectus might also omit other fees, including fees paid to financial intermediaries and brokerage commissions.

Some of these charges can be easy to miss. For example, a redemption fee is not the same as a sales charge because the former is generally used to defray fund costs associated with a shareholder’s redemption and is paid to the fund, not to a broker. Additionally, some funds and brokers impose account maintenance fees, especially on accounts with smaller balances. Be sure to carefully review the fund’s prospectus and website so you aren’t blindsided by extra charges that could eat into your returns.

How mutual fund fees affect your returns

Fees can reduce investment returns in two ways: First, they directly lower the amount of money that remains invested. Second, they reduce the base that can compound over time. Relatively small differences in fees can lead to large differences in returns, which is why cost comparisons matter even when two mutual funds seem broadly similar.

Let’s consider a hypothetical example. Jack starts with an investment of $10,000 in two mutual funds, and each fund earns a hypothetical 6% annual return before fees for 30 years. If one fund has a 0.5% annual cost and the other has a 1.0% annual cost, the lower-cost fund would grow to roughly $49,840, while the higher-cost fund would grow to about $43,219. That’s a difference of roughly $6,621 from just a half-point fee gap.

While this is only an illustration, it shows how compounding can magnify modest cost differences and result in thousands of dollars lost over decades.

Tips to minimize fees and potentially enhance returns

One practical step for minimizing fees and potentially enhancing returns is to compare similar funds side by side rather than considering costs in isolation. FINRA’s Fund Analyzer is designed for this purpose. You can also review the prospectus fee table for each mutual fund to get a clear understanding of operating expenses and other charges.

In addition, it may be helpful to focus on total costs, not just one number. For example, a no-load fund may still have a relatively high expense ratio. Alternatively, a lower-cost index fund may not be the best option if its strategy or holdings don’t match your overall investment goals. Fully understanding your financial objectives and risk tolerance is the first step in deciding which funds might be a good choice for you.

Finally, watch for avoidable friction. Review whether a fund has 12b-1 fees and if a particular share class will add costs. Confirm if you’ll face account or redemption fees, as well as whether high turnover could increase transaction costs within the portfolio. These details can make a meaningful difference over a long holding period, which is why it’s critical to consider total costs – not just the advertised expense ratio.

The bottom line

Mutual fund fees are not just technical details. Expense ratios, sales charges, 12b-1 fees and other charges all affect how much of your money stays invested and how it can compound over time. The good news is that these costs are disclosed, and investors can compare them by reviewing a fund’s prospectus, using fund websites and checking tools such as FINRA’s Fund Analyzer.

The most useful habit is a simple one: Compare similar funds carefully before you invest. Even a small difference in cost can matter over decades, especially when the funds you are comparing have similar strategies and expected returns.
