VOO vs VTI: Dividend/Income Calculator Comparison

Why the calculator shows VOO and VTI as near-twins

Run the projection at any contribution and horizon and the two value bands sit almost on top of each other. That is not a bug in the model — it is the answer. VOO and VTI carry the same 0.03% expense ratio, distribute roughly the same ~1.1% yield, and both grow that per-share dividend at about the long-run U.S. market pace, so when you feed one shared scenario into the engine, there is no lever left to pull them apart. Anyone comparing them mainly on yield is comparing two numbers that are, for planning purposes, the same number. The distinction lives one layer down, in what each basket actually holds, and it barely moves the dividend or after-tax lines the calculator draws.

The real difference: the S&P 500 vs the whole market

VOO tracks the S&P 500 — roughly the 500 largest U.S. companies. VTI tracks the total U.S. stock market, closer to 3,600 holdings, which adds the mid-cap and small-cap tail that VOO leaves out. Because both weight by market value, VTI's largest positions are the same mega-caps that dominate VOO, so the two overlap heavily by weight and the small and mid names sit in the long tail where they nudge, rather than steer, the result. In practice VTI is a slightly broader, slightly more diversified version of the same large-cap exposure; VOO is the tighter, benchmark-aligned slice. Their historical paths have tracked closely, with the gap driven by whether small and mid caps happen to lead or lag in a given stretch — a difference that shows up as a thin band, not a fork, and one this projection deliberately does not try to predict.

Tax and total return: effectively the same treatment

Both funds pay overwhelmingly qualified dividends, taxed at long-term capital-gains rates in a taxable brokerage account and taxed in the year they are paid even when reinvested. Because both yields are low, the annual dividend-tax drag is modest for either, and most of the eventual tax bill for both arrives as capital gains when shares are sold — which is why the Account toggle above moves both projections together rather than separating them. Neither is a covered-call or return-of-capital fund, so neither carries NAV erosion or an ordinary-income distribution warning; the NAV column reads none for both. If you hold either inside a Roth or Traditional IRA, the dividends and gains compound without the annual bill. Some investors discuss VOO and VTI as tax-loss-harvesting partners, but whether they are "substantially identical" for the wash-sale rule is a call for a tax professional, not something this calculator resolves.

Which one tends to fit whom

Neither is the "winner," and the projection is honest about that: on the base-scenario path the two ranges are close enough that the ending numbers rarely settle the choice. VOO tends to suit someone who wants pure S&P 500 exposure — a portfolio that lines up with the benchmark most commentary and many 401(k) core funds quote. VTI tends to suit someone who would rather own the entire U.S. market in a single ticker, small and mid caps included, and not revisit the large-cap-only decision later. Holders who already own an S&P 500 fund elsewhere sometimes pick VTI for the incremental breadth; holders who want to pair cleanly with a separate mid/small-cap or international sleeve sometimes pick VOO to avoid overlap. Both are low-yield, total-return vehicles that pay a small qualified dividend as a side effect, so if current income is the goal, the more useful comparison is either of these against a dividend-growth or covered-call fund — not against each other.
