Overview
IVV and SPY are both broad-market ETFs tracking the S&P 500 Index, giving investors identical underlying exposure to 500 large-cap U.S. companies. The key distinction is cost: IVV charges 0.03% annually while SPY charges 0.10%, a sevenfold difference in expense ratio that translates to meaningful long-term drag on returns. Both distribute dividends quarterly and carry beta of 1.0, meaning they move in line with the index.
How they differ
The dominant difference is the expense ratio. IVV's 0.03% fee is among the lowest available for S&P 500 tracking; SPY's 0.10% is still competitive by historical standards but three times higher. That 0.07 percentage-point gap compounds annually—on a $100,000 position, it costs $70 per year in IVV's favor, growing with asset appreciation over decades.
Beyond fees, IVV and SPY hold nearly identical assets (both track the same index), so their distribution rates are comparable: IVV yields 1.07% and SPY yields 1.02%, a negligible spread that reflects slightly different dividend timing or reinvestment mechanics. Both are enormous funds with deep liquidity—IVV holds $833B in assets and SPY $783B—making bid-ask spreads negligible for most investors. SPY has a longer track record, launching in January 1993 versus IVV's May 2000 inception, though both have decades of performance history.
Who each is best for
IVV: Fits investors building core equity positions over decades and sensitive to cost drag, where a 0.07 percentage-point fee advantage compounds meaningfully into the future. The 0.03% expense ratio appeals to those who want maximum dollars deployed toward actual index holdings rather than management overhead.
SPY: Fits investors who prioritize maximum liquidity and trading volume, or who already hold SPY and see no economic reason to incur the transaction costs of switching. The 0.10% expense ratio remains low by historical standards and, for some, the established market presence outweighs the cost differential.
Key risks to know
- Expense ratio drag on returns: Although both ETFs replicate the index, IVV's lower expense ratio means its net annual return will exceed SPY's by roughly 0.07 percentage points over time. For passive index replication, lower fees directly improve outcomes—a structural advantage that becomes pronounced over multi-decade holding periods.
- Concentration in mega-cap growth: Both funds carry significant overlap with the largest U.S. technology and financial stocks (Apple, Microsoft, Nvidia, Berkshire Hathaway, etc.), meaning they inherit the S&P 500's current mega-cap tilt. A rotation away from large-cap growth could pressure both equally.
- Interest rate sensitivity: Large-cap equities tend to underperform when long-term rates rise sharply, as higher discount rates reduce present values of future earnings. Both funds carry similar interest rate exposure since they hold the same index.
Bottom line
If you prioritize minimizing long-term cost drag, IVV's 0.03% expense ratio delivers a tangible advantage over SPY's 0.10%. If you value liquidity or are already positioned in SPY, the difference is small enough that switching costs may outweigh the fee savings. Both deliver identical S&P 500 index exposure.
