Pay Attention to Your Fund’s Expense Ratio

Expense ratios are fees charged to investors. They represent the cost of managing an investment—notably, to cover the total annual operating expenses of exchange-traded funds (ETFs) and mutual funds. The ETF expense ratio is expressed as a percentage of a fund’s average net assets and can include various operational costs such as:

• Administrative
• Compliance
• Distribution
• Management
• Marketing
• Record-keeping fees
• Shareholder services

The ETF expense ratio, which is calculated annually and disclosed in the fund’s prospectus and shareholder reports, directly reduces the fund’s returns to its shareholders, and, therefore, the value of your investment.

Fund expenses have trended significantly lower, and now many index ETFs offer expense ratios as low as 0.11% per year. The average expense ratio for Vanguard’s ETFs is currently 0.05%, compared to the industry average of 0.22%.

What’s Trending Now?

According to a report published by the Investment Company Institute (ICI) titled “Trends in the Expenses and Fees of Funds, 2023,” expense ratios incurred by investors in long-term mutual funds have, on average, declined substantially for more than 25 years. In 1996, equity mutual fund expense ratios averaged 1.04%, falling to 0.42% in 2023. Hybrid funds went from 0.95% in 1996 to 0.58%, and bond funds dropped from 0.84% to 0.37%.

The trend in lower expense ratios can be attributed to a variety of factors. One of the most notable findings in the report indicated that the drop in the average expense ratios for actively managed and index equity mutual funds was largely due to a rise in interest in low-cost equity mutual funds from investors. Investors have also been shifting to no-load funds, which has also caused funds to rethink high expense ratios.

Expense ratios often vary inversely with fund assets, meaning that as a fund’s assets increase, its fixed costs likely represent a smaller percentage of its net assets. This means that its expense ratio can decrease correspondingly.

Despite trends indicating an overall decrease in fees across many fund categories, investors should still pay attention to expense ratios because even small differences in fees can have a significant impact on your investment over time.

Understanding Costs and Expense Ratios

The expense ratios for mutual funds generally tend to be higher than those of ETFs. While ETF expense ratios average out to about 0.22%, mutual fund costs can be significantly higher. Operating fund costs vary greatly depending on the investment category, investment strategy, and the size of the fund. Those with higher internal costs generally pass on these costs to shareholders through the expense ratio. So If a fund’s assets are small, its expense ratio might be relatively high, because the fund has a restricted asset base from which to meet its expenses.

Compare funds that own similar types of investments. For example, international funds are typically very expensive to operate because they invest in many countries and may have staff all over the world. Large-cap funds, on the other hand, tend to be less expensive to operate. While it is reasonable to compare expense ratios across multiple international funds, it would not make sense to compare the costs of an international fund against a large-cap fund.

When researching investments, there are several ways you can determine the expense ratio of a fund:

• Fund Prospectus: If you are already a shareholder, the prospectus will be mailed or sent electronically to you each year. The expense ratio is typically found under the “Shareholder Fees” heading. You can also view the prospectus on the fund company’s website.
• Financial News Websites: Websites such as Google Finance and Yahoo! Finance have expense ratio information for mutual funds and ETFs. Type in a fund’s ticker symbol to view this information.
• Fund Screeners: Many ETF and mutual fund screeners are available online. You can search by category or group (i.e., equity, bond, money market, international) and compare expense ratios across similar investments. FINRA’s Mutual Fund Expense Analyzer, for example, allows you to compare up to three mutual funds (or ETFs) or the share classes of the same mutual fund. The tool estimates the value of the funds and the impact of fees and expenses on your investment.
• News Journals: Print newspapers, such as Investor’s Business Daily and The Wall Street Journal print information regarding funds, including expense ratios.

How Rates Affect Investments

To see how expense ratios can affect your investments over time, let’s compare the returns of several hypothetical investments that differ only in expense ratio. The following table depicts the returns on a $10,000 initial investment, assuming an average annualized gain of 10%, with different expense ratios (0.5%, 1%, 1.5%, 2%, and 2.5%):

As the table illustrates, even a small difference in expense ratio can cost you a lot of money over time. If you invested $10,000 in the fund with a 2.5% expense ratio, the value of your fund would be $51,524 after 20 years. Had you instead invested your $10,000 in the fund with a lower expense ratio, such as the one at 0.5%, then your investment would be worth $64,122 after two decades. This is a 24% improvement over the more expensive fund.

Keep in mind, this example examines funds whose only differences are the expense ratios: all other variables, including initial investment and annualized gains, remain constant (for the example, we must assume identical taxation as well). While two funds are not likely to have the same performance over 20 years, the table illustrates the effects that small changes in expense ratio can have on your long-term returns.

The Bottom Line

While it’s important, a fund’s expense ratio is not the only consideration when analyzing and comparing fund investments. There are numerous avenues to purchase mutual funds, including online, and investors must also consider a variety of factors before buying, like each fund’s individual:

• Sales charges
• Taxes
• Age and size
• Risks and volatility
• Recent changes in operations (for example, has the fund’s investment adviser changed?)
• Impact on your portfolio diversification

It should be noted that a fund’s expense ratio represents your cost of owning the fund—not purchasing or redeeming the fund (sales loads). Any initial or deferred sales charges, transaction fees, or brokerage charges are not included in the expense ratio. All of these factors should be taken into consideration prior to making any investment decisions. With research, you can find funds that meet your goals and objectives while leaving more money in your portfolio.
