Same ingredients, different box

A total-market index mutual fund and ETF can track the same universe. You are choosing how you buy it, what it costs, and taxable events.

Fees and the 401(k) exception

If the 401(k) only offers a 0.80% active fund, contribute to the match, then put extra in an IRA ETF. Do not skip the match to chase a prettier ticker.
