Let’s assume someone puts $10,000 in a mutual fund, leaves it there 20 years, and gets an average annual return of 10 percent. If the fund had an expense ratio of 1.5 percent, the fund is worth $49,725 at the end of 20 years. However if the fund had an expense ratio of 0.5 percent, it would be worth $60,858 at the end of 20 years.
