Vti stock and ITOT both target the entire investable U.S. equity market, but ITOT’s 0.03% net expense ratio puts a hard number on the cost gap. The two funds look almost interchangeable on exposure, yet the difference between CRSP and S&P index rules can matter more than the ticker.
ITOT's 0.03% fee edge
0.03% is ITOT’s net expense ratio, and that is the clearest published cost in the comparison. ITOT also carries NVIDIA at 6.69%, Apple at 5.88%, Microsoft at 4.34%, Amazon at 3.21%, and Alphabet’s Class A shares at 2.64%, showing how heavily both funds lean on the same mega-cap names.
7.42% and 7.83% were the year-to-date returns through May 7 for VTI and ITOT, respectively. Over the trailing year, VTI gained 30.44% while ITOT gained 32.02%, a spread that is small relative to the funds’ near-identical job of holding the whole U.S. market in one ticker.
CRSP vs S&P TMI
CRSP US Total Market Index uses banded reconstitution to reduce turnover, while the S&P Total Market Index relies on committee oversight and profitability screens. Those rules do not change the broad-market mission, but they do affect which names enter the portfolio and how often holdings shift.
VTI tracks CRSP US Total Market Index, and ITOT follows S&P Total Market Index, so the practical question is less about access than about structure. Both ETFs hold identical mega-cap positions including NVIDIA, Apple, and Microsoft, which means the competition often comes down to small frictions rather than different market exposure.
Vanguard's Brokerage Link
17.39 years is the longer-window return figure shown for one of the funds, and ITOT’s 302.43% ten-year return gives investors one more hard data point to compare against VTI’s shorter-term numbers. The article also says VTI’s structural link to the underlying mutual fund is a quiet advantage for Vanguard loyalists or anyone using a Vanguard brokerage.
Switching out of VTI in a taxable account typically costs more in capital gains than the marginal differences between the two funds. For an investor already holding one of them, the decision is not just about a 0.03% fee on ITOT; it is about whether the tax bill and brokerage fit overwhelm the small cost and method differences.
