How much do VOO and VTI overlap?+
A lot. Both track the broad US stock market, so the holdings overlap is very high. That is why most investors pick one or the other, not both. Our overlap checker shows the exact percentage, plus how VTI’s small- and mid-cap tilt differs from VOO. If you already hold one, the comparison tells you whether adding the other changes anything. It is the single most useful page in the best ETF comparison tool we could build.
Should I own both SPY and VOO?+
Usually not. Both track the S&P 500, so owning both mostly duplicates your exposure and adds complexity. The real difference is cost: VOO’s expense ratio is lower than SPY’s, so long-term holders generally keep more with VOO. Our head-to-head pages show the fee gap and return difference side by side.
How much does a higher expense ratio cost over 20 years?+
More than it looks. On a $100,000 portfolio growing at 8% a year, a 0.20% fee versus 0.03% costs tens of thousands over two decades through compounding. Our ETF fee calculator turns any expense-ratio comparison into a dollar figure, so the trade-off is concrete. That is why we rank the lowest expense ratio ETFs in every category.
VOO vs IVV vs SPLG expense ratio comparison+
All three track the same index and perform almost identically. The difference comes down to expense ratio, fund size and your broker. VOO and IVV are the giants; SPLG undercuts both slightly on fees. Our pages lay out expense ratios, returns and holdings so you pick on facts, not brand.
ETF vs mutual fund expense ratio comparison+
ETFs usually win on cost. Index ETFs run lean portfolios with low turnover, while many mutual funds charge 0.5% or more for active management. ETFs also trade intraday and tend to be more tax-efficient. Our screener compares ETF vs mutual fund expense ratios within each category so the cost gap is visible.
