Breadth of holdings is the main difference
VOO tracks the S&P 500, limiting its holdings to roughly 500 of the largest U.S. companies. VTI adds mid- and small-cap u.s. stocks on top of the large-caps voo holds. Because large-cap companies dominate total U.S. market capitalization, the two funds have historically tracked each other closely, even though VTI technically holds far more individual companies.
Which should you choose?
If you specifically want exposure to only the largest, most established U.S. companies, VOO does that directly. If you’d rather hold the entire U.S. equity market in one fund — including smaller companies that might grow into tomorrow’s large-caps — VTI is built for that. Neither is objectively “better”; they reflect a different choice about how much of the market to own.
Since both funds have historically produced similar growth and dividend characteristics, the VOO calculator can serve as a reasonable rough proxy for projecting a VTI investment as well, though the two funds are not identical.
