Impact of Expense Ratios

Jane Bryant Quinn in AARP Bulletin, April 2019, p. 33 states the following:

Assuming that a $10,000 investment you made in a zero-fee fund grew an average of 6 percent annually, you'd end up with roughly $32,070 after 20 years. The same fund with a 1.1 percent annual fee (also called an expense ratio) would net you only about $25,710, or $6,360 less.

The average stock mutual fund in 2017 charged 1.1%.  $25,710 versus $32,070 is a 20% hit. As a matter of perspective retirees target 4% as a drawdown rate in retirement.
