KEY POINTS
  • When it comes to saving for retirement, most investors focus on their returns yet many have no idea how much the fees they’re paying are eating into those earnings.
  • To see if your fees are too high, check the expense ratios on the mutual funds you are invested in.
  • Consider a lower-fee mutual fund if you have several funds in your 401(k) that have an expense ratio over 1 percent.

When it comes to saving for retirement, every little bit helps.

That's why it's important to keep a careful eye on the fees you are coughing up for your mutual and exchange-traded funds, which take a huge toll on potential investment returns over time.
