Fund face-off

VOO vs VTI: what's the difference, and which should you buy?

VOO and VTI are two of Vanguard's most popular funds. They're very similar, and both are great low-cost choices. The main difference is how many companies they own.

Key points

  • VOO owns about 500 large U.S. companies (the S&P 500).
  • VTI owns thousands of U.S. companies of all sizes.
  • Both charge just 0.03% a year, and their returns have been very close.

They overlap a lot

The biggest companies make up most of VTI's value. Those are the same companies in VOO. So even though VTI owns thousands more companies, it moves almost the same as VOO most days.

The extra companies in VTI are medium and small businesses. Over some periods, small companies do better. Over others, like the last 10 years, big companies have won.

A 30-year example

$200 every two weeks at each fund's approximate 10-year rate:

YearsVOO (13.5%)VTI (13.0%)
20$474,641$446,675
30$1,788,296$1,617,910

The gap comes from large companies beating small ones over the last decade. That won't always happen. Over other long periods, the two have traded places.

Which should you pick?

Similar funds from other companies include FXAIX and SWPPX (S&P 500) and VTSAX (total market, as a mutual fund).
