mutual fund expense ratio
If you’re investing in mutual funds or exchange-traded funds (ETFs), the fund manager will charge fees to cover their various expenses. Those fees are collectively rolled into what’s known as an expense ratio, which is expressed as a percentage. This is the portion of your total account value that’s removed annually in fees. For more insight into mutual fund expense ratios and how to lower your costs, consider finding a trusted fiduciary financial advisor in your area.

Understanding and comparing funds’ expense ratios is an important task for any investor before you select any investment vehicle: Fees vary widely, and they can have a significant impact on your long-term savings. Consulting with a financial advisor can help you navigate these fees and make sense of the fine print, but we’ll cover the essentials here.

How the Expense Ratio Is Calculated

The costs that go into an expense ratio vary greatly from fund to fund. But most expense ratios include outlays for fund management, marketing, recordkeeping, administration, compliance and shareholder services. With many mutual funds, a 12b-1 fee, which covers a fund’s marketing and distribution costs, makes up a large proportion of the expense ratio.

The fees are bundled into a ratio that is expressed as a percentage of your total assets with that fund, and deducted from the net assets on an annual basis. For example, a fund with $1,000 might have an annual expense ratio of 1%, meaning that $10 is deducted from your account to cover costs every year.

Some of the fund’s costs are not included in the expense ratio, such as sales commissions paid to a broker who sold you the fund (these are referred to as loads), or trading commissions and account services fees. These are classified as debits, and they are listed on account statements.

You can find the expense ratio for a fund when comparing funds on a brokerage site, as well as on the fund’s prospectus. They aren’t typically listed in your account statements, though.

Different Funds Offer Different Expense Ratios

On average, an equity mutual fund has an expense ratio of 0.55%, according to the most recent survey by the Investment Company Institute. But this is just an average. Since the amount of effort that goes into managing funds depends greatly on its investment strategy, it stands to reason that expense ratios also demonstrate considerable range. The ratio calculation depends on what type of fund you’ve invested in and who manages it.

Mutual funds that actively buy and sell securities will typically carry expense ratios between 0.50% and 1.50%. Some actively managed funds that employ options and other high-cost hedging strategies have higher fund expense ratios, though it’s rare to see a ratio north of 2.50%. Still, there are many mutual funds that employ more passive investing strategies and thus have lower expenses. That ICI report found, for instance, that target-date funds (which are commonly found in 401(k)s) have an average ratio of 0.40%. And index funds have much lower fees (more on them in a bit).

While exchange-traded funds have many similarities to mutual funds, they tend to have lower expense ratios, typically below 0.50%. That’s mainly because they’re more likely to use passive management strategies, including index investing. Such strategies don’t involve as much analysis as actively managed mutual funds.

Index funds – a group that includes both mutual funds and ETFs – are the quintessential passively managed funds, attempting to simply track the rise and fall of a market index. As you might expect given this passive approach, they generally have expense ratios at the low end of the scale: 0.25% or even below 0.10%. Vanguard, considered the pioneer of index investing, has stock index funds with expense ratios below 0.50%, which means that an investment of $10,000 would lose less than $5 a year to fees. Index funds are popular with many investors in part due to these low management costs.

Some investment companies, particularly online or robo-investors, have made low-cost investing a specialty. Generally, a passive investment vehicle will carry a lower expense ratio than an active vehicle. There are always exceptions, and rates can vary across type. This is one reason it can be wise for investors to explore multiple options and read prospectuses that investment companies offer.

Why Expense Ratios Matter

Investors seek out low expense ratios, because fund expenses can have a direct impact on fund returns. Assuming all else is equal, the higher the expense ratio, the lower your return. And just as a small increase in your savings rate of annual returns can compound over the years, so too can a small increase in expense ratio take a big bite out of your nest egg over many years of investing.

Consider a fund that delivers a 5% annual return or profit. An expense ratio of 1% may sound minuscule, but it means that 20% of your fund’s earnings take a detour to the fund company’s coffers – year in, year out. In contrast, a fund with a 0.25% ratio gives up just 5%.

A handy investment calculator can show you how much gain you can expect over time. And the same goes for the expense ratio: that money also compounds, and over a decade or two, the difference between 1% and 0.25% can become very large indeed. And because fund expense ratios are percentages, not flat fees, the more money you have invested, the more you’ll pay.

Is It a Good Ratio? Depends on Your Returns

Generally, smaller funds can have higher expense ratios, since they have fewer assets to cover costs and thus need more from each investor. Funds that invest in international markets, which require more analysis and observation, can also require high expense ratios.

But the most significant factor determining what a “good” expense ratio is comes down to the investment strategy. Actively managed mutual funds command higher expense ratios, typically above 0.75% on average. Average expense ratios for passively managed equity index mutual funds and bond index funds are much smaller, typically under 0.10%.

At the end of the day, though, what really justifies an expense ratio is the fund’s returns, not its strategy. Paying more for an actively managed mutual fund is worth it if that fund outperforms the market significantly. It comes down to simple math: If a mutual fund charges 0.70%, but an S&P 500 index fund would have cost only 0.05%, then the mutual fund would have to beat the S&P 500 by more than 0.65% to justify the increased costs.

While some funds do indeed outperform in this way, active management hasn’t shown a consistent ability to beat the market over the long-term. That’s why many investors have come to prefer low-cost index funds and passive management strategies – which in turn has helped to bring down average expense ratios.

The Takeaway

While expense ratios are important, they are not the only factor that determines the quality of a fund. An investor seeking a high-yield investment may see a high expense ratio as an acceptable cost for a strategy that takes more risks but has the potential to deliver greater returns. Remember, though, that an expense ratio is charged on your total account value, not the gains you see in the market. That means that you’re paying the ratio even if the fund loses value.

Ultimately, the best expense ratio may belong to the fund that reflects the goals of the investor and measures up to its closest competitors.
