How this works
Results use monthly total-return data (adjusted close) from Yahoo Finance, with dividends reinvested (DRIP) always on. Both ETFs are modeled over the exact same window and with identical contributions, so the only variable is fund performance. This calculator is for illustrative purposes only. Past performance does not guarantee future results. Not investment advice.

Frequently Asked Questions
Is VOO or IVV better for long-term investing?
They are functionally interchangeable. Both track the S&P 500, both charge 0.03%, both are open-end ETFs with identical tax treatment, and both have delivered virtually identical total returns since VOO launched in 2010. The decision comes down to issuer preference and whether your broker trades one commission-free.
What is the difference between VOO and IVV?
The core differences: issuer (Vanguard vs BlackRock iShares), AUM (VOO ~$1.51T, IVV ~$582B), and launch date (IVV is a decade older). Index tracked, expense ratio, and ETF structure are identical. Trading costs, holdings, and tax outcomes are essentially the same.
Can I hold both VOO and IVV?
You can, but there's no diversification benefit. They hold the same roughly 500 stocks in the same weights. Holding both is effectively holding one position in two accounts. Most investors pick one based on issuer or broker, not own both.
Does IVV or VOO have better tax efficiency?
Both are exceptional. Both use the ETF creation-redemption mechanism to flush appreciated positions without triggering shareholder capital gains. Neither has made a meaningful cap-gains distribution in over two decades. For taxable accounts, either is as tax-efficient as index funds get.
Which has better options liquidity, VOO or IVV?
IVV is slightly deeper than VOO, but both trail SPY by a wide margin. If you actively trade options or sell covered calls, SPY is still the standard. For buy-and-hold investors the gap is irrelevant.
