How a Mutual Fund’s Expense Ratio Impacts Your Bottom Line
There are literally thousands of mutual funds out there and many of them claim to be diversified, low cost, low fee, etc. But if there’s one thing that has the most direct impact on a fund’s return, it’s the expense ratio(ER). When comparing similar funds, I primarily look at the expense ratios first and foremost. Most mutual funds have expense ratios varying from about 0.1% to almost 4%. With the abundance of low cost mutual funds available today, there is no reason to ever consider ER’s of 1% or higher.
Some of us might be stuck with certain options in 401k plans. But for everyone else, finding funds with low ER should be a priority. An expense ratio is what it costs an investment company to offer a mutual fund. Actively managed funds tend to have higher ER’s because the fund manager is constantly buying/selling stocks while passively managed funds are the exact opposite. They buy/sell very infrequently and require little active management.
Stock Market is a Zero Sum Game
The stock market is a zero sum game meaning that a participant’s gain or loss is exactly balanced by the losses or gains of the other participant(s). If the total gains of the participants are added up, and the total losses are subtracted, they will sum to zero.
Every dollar made by one investor is a dollar lost by another investor. This is a fact. The brokerage fees and expense ratios actually make this a negative sum game, meaning most traders lose. In order to achieve returns like the 10% average annual return of the Dow Jones, investors need to look for the lowest cost funds.
Low Cost Funds
If some active fund managers win, then others must lose. The smart investor will not leave their returns up to chance. Investing in low cost index funds will always return close to the average rate of return for that particular index. Low cost index funds attempt to mimic the exact holdings of the index they follow. Let’s take a look at Vanguard’s 500 Index Fund(VFINX):
- Invests in 500 of the largest U.S. companies
- Expense Ratio = 0.17%, 85% lower than average ER for similar funds
- 10 year avg. annual return = 4.02% (Compared to S&P 500 return of 4.12%)
Expense Ratios Can Cost You Hundreds of Thousands
Here’s an example of how much impact a 2% ER fund can have:
Max has his 401k invested in a low cost 500 index fund with a 0.2% ER. James has his 401k invested in an actively managed fund with 1% ER. Over 40 years, let’s assume both funds have the same rate of return of 5% per year(before fees). In each case we start off with $0 and contribute a modest $10,000 to our 401k. Using a 401k calculator, we see that after 40 years:
Max’s 401k value, using a low cost 500 index fund: $1,205,868
The conservative numbers shown above illustrate the impact of expense ratios. Imagine what the difference would be if you max out your 401k and contribute $5k annually to an IRA. Expense ratios can literally make a million dollar difference. I actively avoid high fee funds for this reason. Actively managed funds will never beat low cost passive index funds over extended periods of time. The indexes as a whole will probably go up and through smart investing like this, you can expect to see a nice return on your money.
Do you know what the fees are for your 401k funds? Do you invest in actively managed funds? If so, please explain why?
