VOO vs VTI: Which Vanguard ETF Is Better in 2026?
Two of Vanguard's most popular ETFs compared head-to-head
UPDATED April 17, 2026 — Data verified quarterly
What I Actually Did: Picking VTI During My March 2026 Rebalance
Last checked: April 2026. When I rebalanced my portfolio in March 2026, I actually pulled the numbers on both. VOO's 10-year return through Feb 2026: 12.8% annualized. VTI: 12.6%. The 0.2% gap over 30 years on a $10K investment compounds to roughly $5,400 difference — real, but meaningless compared to decisions like "am I actually contributing $500/month" or "am I paying a 1% advisor fee." I ran the same projection for a $100K position and the gap was ~$54K over 30 years — still inside the noise of normal market volatility.
I went with VTI for the 3,500+ small and mid-cap exposure VOO lacks. My logic: if the next decade looks like the 1975-1985 or 2000-2010 periods (when small caps quietly beat the S&P 500), I want that exposure baked in. If large caps dominate again like 2010-2024, I still capture ~80% of VOO's return because the S&P 500 is the dominant weight inside VTI anyway. So VTI feels like the strictly-better option for an investor who doesn't want to make another decision for 30 years.
The actual trade: I sold $28,400 of VOO in my Roth IRA (no tax event), bought $28,400 of VTI the same afternoon. I kept VOO in my taxable account because selling would have triggered $6,200 in long-term capital gains. Moral: rebalance inside tax-advantaged accounts first, leave taxable positions alone.
VOO and VTI are the two most popular Vanguard ETFs and among the most widely held funds in the world. VOO tracks the S&P 500 — the 500 largest U.S. publicly traded companies — while VTI tracks the CRSP US Total Market Index, covering virtually every publicly traded stock in America, including small-cap and mid-cap companies. Both charge rock-bottom fees and deliver broad U.S. equity exposure, making the choice between them more nuanced than it appears.

| Index Tracked | S&P 500 | CRSP US Total Market |

What Are the Key Differences?
- Breadth of coverage: VOO holds only the 500 largest companies, while VTI covers the entire U.S. market — roughly 3,600 stocks including small and mid-cap companies that VOO excludes.
- Small-cap exposure: VTI gives you ~8% exposure to small-cap stocks and ~17% to mid-caps. These segments historically have higher growth potential but also more volatility.
- Performance correlation: VOO and VTI have a 99%+ correlation over long periods because the S&P 500 makes up about 80% of VTI's total holdings by market cap.
- Dividend yield: VOO typically pays a slightly higher dividend because large-cap companies tend to distribute more income than small-cap growth companies.
- Simplicity: VOO is the most widely recognized benchmark — "the market" in most financial discussions refers to the S&P 500. VTI is technically more complete.
- Small-cap premium: Academic research suggests small-cap stocks may deliver a long-term return premium, giving VTI a slight theoretical edge over very long horizons.
- Rebalancing: S&P 500 inclusion requires a committee decision and profitability requirements. The CRSP index uses rules-based inclusion with no committee.
VOO Advantages
- Tracks the world's most recognized index
- Slightly higher dividend yield
- Only holds profitable, established companies
- Marginally higher 10-year return (by ~0.2%)
- More liquid with tighter bid-ask spreads
VTI Advantages
- Broader diversification (3,600+ stocks)
- Includes small/mid-cap growth potential
- True total market exposure in one fund
- Lower share price makes it more accessible
- No committee-based selection bias
Which Should You Choose?
Choose VOO if:
- You want exposure to the most established, profitable U.S. companies
- You prefer tracking the S&P 500 benchmark that dominates financial media
- You are building a portfolio with separate small-cap or international allocations
- You want slightly higher dividend income
Choose VTI if:
- You want the simplest possible U.S. equity allocation — one fund, total coverage
- You believe small-cap stocks will outperform over your investment horizon
- You prefer maximum diversification without managing multiple funds
- You are a beginning investor who wants a single "set it and forget it" holding
The Bottom Line
For most investors, the difference between VOO and VTI is academically interesting but practically insignificant. Over any 10+ year period, their returns are within 0.1-0.3% of each other. If you already hold one, there is no compelling reason to switch to the other. If you are choosing for the first time, VTI offers marginally more diversification while VOO offers marginally higher dividends. You genuinely cannot go wrong with either.

Frequently Asked Questions
Is VOO or VTI better for long-term investing? +
Both are excellent long-term investments. VTI provides broader diversification by including small-cap and mid-cap stocks alongside the S&P 500 large caps. VOO focuses exclusively on the 500 largest U.S. companies. Historically, their returns have been nearly identical over 10+ year periods, with VTI occasionally outperforming when small caps rally. For most long-term investors, either choice is sound, though VTI offers marginally more diversification.
Can I hold both VOO and VTI? +
You can, but there is significant overlap. VTI already includes every stock in VOO since the S&P 500 is a subset of the total U.S. stock market. Holding both means you are overweighting large-cap stocks. Most advisors recommend choosing one or the other rather than holding both, since the diversification benefit of combining them is minimal.
What is the difference in expense ratio between VOO and VTI? +
Both VOO and VTI have identical expense ratios of 0.03%, which is among the lowest in the industry. On a $10,000 investment, you pay just $3 per year in fees for either fund. This means cost is not a differentiating factor when choosing between them.
Which ETF has better dividend yield, VOO or VTI? +
VOO typically has a slightly higher dividend yield than VTI, usually by 0.05-0.15 percentage points. This is because large-cap companies in the S&P 500 tend to pay higher dividends than the smaller companies included in VTI. As of early 2026, VOO yields approximately 1.35% while VTI yields around 1.30%.
Should beginners buy VOO or VTI? +
For beginners, VTI is often the slightly better choice because it provides instant diversification across the entire U.S. stock market with a single purchase. You get exposure to large, mid, and small-cap companies without needing to think about portfolio construction. That said, VOO is also perfectly fine for beginners and the performance difference is minimal.
