Overview
IVV and SPY are both ETFs tracking the S&P 500 Index, offering exposure to 500 large-cap U.S. companies. The key distinction is cost: IVV carries a 0.03% expense ratio while SPY charges 0.10%, a difference that compounds meaningfully over decades of holding. Both have massive scale ($901B and $812B in AUM respectively) and identical beta of 1.0, so performance before fees should track the index almost identically.
How they differ
The primary difference is the expense ratio. IVV's 0.03% annual cost is roughly one-third SPY's 0.10%, translating to roughly $7 per $10,000 invested annually in IVV versus $10 in SPY. Over a 30-year holding period, that gap alone compounds to meaningful underperformance for SPY even if both funds track the index perfectly. Distribution rates are nearly identical (IVV at 1.02%, SPY at 0.98%), with both paying quarterly. IVV was founded in 2000; SPY has been around since 1993 and is the older, more widely traded fund by historical precedent, though AUM favors IVV by $89 billion.
Who each is best for
IVV: Fits investors focused on minimizing total cost of ownership and building long-term core equity positions where fee drag compounds significantly over decades.
SPY: Fits investors prioritizing maximum trading liquidity, name recognition, or those whose brokerage or investment platform may offer superior execution or integrated tools around SPY specifically.
Key risks to know
- Index concentration risk. Both funds hold the same 500 companies with identical market-cap weighting. Mega-cap technology stocks (Microsoft, Apple, Nvidia, Tesla, Amazon) represent a material fraction of the index; a sector downturn or rotation away from large growth names affects both equally.
- Expense ratio gap compounds slowly but steadily. The 0.07 percentage-point difference between the two is small in any single year but produces cumulative underperformance for SPY of roughly 2.1% over a 30-year period assuming identical index returns, all else equal.
- Market-wide equity risk. Both funds move dollar-for-dollar with broad equity market sentiment. Economic recession, rising interest rates, or multiple compression in large-cap growth stocks affect both identically.
Bottom line
If you're building a core S&P 500 holding for the long term, IVV's lower expense ratio provides a measurable cost advantage that compounds over time; if maximum intraday trading volume and established brand familiarity matter to your execution or brokerage workflow, SPY's liquidity edge and longer history may offset its higher fee.
