Vanguard ETF vs mutual fund
See my comment for some discussion of why one might choose an identical fund over an ETF.  As to why someone would choose the higher cost fund in this instance ... The Admiral Shares version of the fund (VFIAX) has the same expense ratio as the ETF but has a minimum investment of $10K.  Some investors may want to eventually own the Admiral Shares fund but do not yet have $10K.  If they begin with the Investor Shares now and then convert to Admiral later, that conversion will be a non-taxable event.  If, however, they start with ETF shares now and then sell them later to buy the fund, that sale will be a taxable event. Vanguard ETFs are only commission-free to Vanguard clients using Vanguard Brokerage Services.  Some investors using other brokers may face all sorts of penalties for purchasing third-party ETFs.  Some retirement plan participants (either at Vanguard or another broker) may not even be allowed to purchase ETFs.
