Fund data from Vanguard fact sheets F0968 (VOO) and F0970 (VTI), as of June 30, 2026, fetched October 4, 2026. Average daily volume and bid-ask spreads are omitted because they are not on those fact sheets. For education only, not investment advice.

Sources: Vanguard fact sheets as of June 30, 2026. Periods under one year are cumulative; longer periods are average annual NAV returns with dividends reinvested. Past performance does not guarantee future results.
Since-inception returns are not comparable across funds because VTI launched in 2001 and VOO in 2010. Prefer the matched 1, 3, 5 and 10 year rows.
Our VOO and VTI fund pages show different 1-year figures (+15.5% and +15.1%) because those pages measure share-price change without distributions from Sep 30, 2025 to Oct 2, 2026, while Vanguard's figures above are NAV total returns to June 30, 2026.

Which should you buy, VOO or VTI?
Choose VOO if you want a pure S&P 500 holding that matches the most-cited U.S. large-cap benchmark. Choose VTI if you want one-fund U.S. stock exposure that includes mid-cap and small-cap shares VOO leaves out. Both cost 0.03%, so pick based on coverage, not fees. Selling either in a taxable account can create capital gains tax.
VOO fits you if:
- You want the S&P 500 specifically, including for benchmarking against large-cap news and research.
- You already own mid-cap or small-cap funds and do not want to duplicate them inside a total-market ETF.
- You prefer the slightly larger ETF share-class asset base Vanguard reported for VOO as of June 30, 2026.
VTI fits you if:
- You want one U.S. stock ETF that includes large-, mid- and small-cap companies.
- You are building a simple two-fund or three-fund portfolio and want total-market U.S. equity exposure.
- You accept a little more small-cap volatility for broader coverage (VTI's 3-year standard deviation was 13.45% vs 13.06% for VOO).
Consider neither as your only holding if you need international stocks or bonds. See our VXUS and BND pages, and ETF statistics.
