An expense ratio represents the cost to own an ETF over the course of the year

The total cost of owning an ETF is the sum of the holding costs and the transaction costs

Transaction costs include things like brokerage commissions, or the fee that a broker charges to enact a trade. However, in recent years, most brokers have essentially eliminated commissions on ETF trading.

Fees can eat away at your 401(k)

Every investment plan has an expense ratio—a percentage of the total assets that goes to the investment manager in the form of fees. Because 401(k) plans are so common, and many of their participants are not savvy investors, the relative expense ratio for them has often excessively increased.
