Fees and Expenses: Do They Really Matter?

Written by Scott MacKillop | Aug 8, 2024 8:20:38 PM

Fees and expenses are two of the most important factors to consider when investing. You can’t control the direction of the financial markets, but you can control what you pay to invest.

Every mutual fund or exchange traded fund (ETF) in your portfolio has what’s called an “internal expense ratio.” This is the amount charged by the fund company for managing the fund.

Fees Eat Up Returns

The internal expense ratios for different funds, even funds with similar investment objectives, can vary widely. Those differences can make a big difference in the performance of your portfolio over time.

Investment costs might not seem like a big deal, but they add up and compound over time along with your investment returns. You don’t just lose the amount you pay in fees—you also lose all the growth that money would have generated for years into the future.

Here’s an example. Dozens of funds in the Morningstar database track the S&P 500 index. Many have internal expense ratios of 0.05% or less, while others have internal expense ratios of 1.00% or more. That’s quite a big range for funds that track the same index.

The chart below shows the growth of $1 million invested in the S&P 500 index over the 25 years ending in 2022. It also shows the return you would have received if you had invested $1 million in an S&P index fund with a 0.05% expense ratio vs. a fund with a 1.00% expense ratio.

The difference between investing in the low expense ratio fund vs. the high expense ratio fund—$1,320,361— comes out of your pocket. This amount could fund years of retirement!

Paying attention to fund expenses can make a huge difference in your financial well-being.

 

Low Fees Are Correlated with Better Performance

Mutual fund and ETF expense ratios can have a significant impact on the performance of an investor’s portfolio. They are also a strong predictor of future fund performance.

Many studies have shown that funds with low expense ratios have a performance edge over funds with higher expense ratios. A 2010 study conducted by Morningstar tracked the performance of funds in different asset classes over various time periods. In every asset class over every time period, the low expense funds outperformed the high expense funds.

Vanguard did a similar study using data through 2019 and came to the same conclusion—lower expenses and higher performance go together.

The results of that study are shown below.

 

Average Annual Returns

10 Years Ending in 2019

Notes: All mutual funds in each Morningstar category were ranked by their expense ratios as of December 31, 2019. They were then divided into four equal groups, from the lowest-cost to the highest-cost funds. The chart shows the ten-year average annualized returns for the median funds in the lowest-cost and highest-cost quartiles. Returns are net of expenses, excluding loads and taxes. Both actively managed and index funds are included, as are all share classes with at least ten years of returns. Data reflect the ten-year period ended December 31, 2019. Benchmarks reflect those identified in each fund's prospectus. "Dead" funds are those that were merged or liquidated during the period.

You can see that, on average, funds with lower costs outperformed funds with higher costs.

This outcome may seem counterintuitive in a world where we often associate higher cost with higher quality. But in an investment context it makes sense. Fees and expenses are a drag on performance. The more an investor pays in fees, the less they get to put into their own pocket.

Interestingly, lower fees, themselves, do not completely explain the performance advantage that low-cost funds have over high-cost funds. Whatever the reasons, managers of low-cost funds, on average, generate higher performance than managers of high-cost funds.

 

Controlling Portfolio Turnover Reduces Portfolio Expenses

Keeping an eye on expenses is important to long-term investment success. Mutual fund and ETF expense ratios are a big part of that, but expense ratios don’t include trading costs. Trading costs, like a fund’s expense ratio, are a drag on performance.

Every time a fund buys or sells a security it incurs trading costs. The more a fund buys and sells securities, the greater those costs. So, it’s important to track how frequently funds buy and sell the securities that they hold.

A fund’s “turnover rate” is the measure of how frequently it trades the securities that it holds. For example, a stock mutual fund with a 100% turnover rate, on average, trades all the stocks it holds once a year. A fund with a 25% turnover rate only trades about a quarter of its holdings in a year. Obviously, funds with higher turnover rates experience higher trading costs.

You might think trading costs have a small impact on the long-term value of a portfolio, but that is not the case. Experts like Vanguard Group founder, John Bogle, have estimated that a stock fund with a 100% turnover rate costs investors roughly 1% of their portfolio value each year.1

In the chart below, you can see the impact that this would have on a $1 million portfolio over the 25-years ending in 2022 compared to the return of the S&P 500 index.

A 1% bite out of your portfolio’s returns costs $1,398,576 over 25 years. Turnover matters.

Higher trading costs are fine if they enhance fund performance after taking those costs into account. But the academic research on this topic suggests that, on average, higher turnover rates do not result in better fund performance.2 Therefore, it’s important to monitor the turnover rates of the funds within a portfolio and keep them low when possible.
