VOO’s 0.03% expense ratio is a marketing illusion. A closer look reveals hidden costs that could cost the average investor $50,000 more over 20 years compared to a rival ETF.
That is the core finding from a new analysis by AOL, which argues that Vanguard’s flagship S&P 500 fund, the Vanguard S&P 500 ETF (VOO), masks real costs that cheaper competitors charge half as much to cover.
The trap is not the stated fee. It’s everything else.
1. The Real Cost of VOO: Beyond the Expense Ratio
VOO’s 0.03% expense ratio is among the lowest in the industry. But total cost of ownership includes bid-ask spreads, tracking error, and trading friction. During market downturns, liquidity dries up. A Yahoo Finance analysis of “1 Top Vanguard ETF to Buy Before the Next Market Crash” notes that VOO’s average bid-ask spread during the 2020 crash widened to 0.05%, compared to a rival ETF’s 0.02%.
These gaps compound. A 0.02% spread on a $100,000 trade costs $20. Over dozens of trades in a volatile year, that adds up to hundreds of dollars. Tracking error—the difference between the fund’s return and the index—adds another 0.01% to 0.03% annually for VOO, according to Morningstar data.
Over 20 years, these hidden costs can erode returns by an estimated 0.10% to 0.15% annually. That does not show up on the fee sheet.
2. Meet the Rival: Why a Cheaper ETF Charges Half as Much
The AOL article highlights a direct competitor: the iShares Core S&P 500 ETF (IVV), with a 0.03% expense ratio that is identical on paper. But IVV’s total cost of ownership is lower. Its tighter tracking error (averaging 0.01% vs. VOO’s 0.03%) and narrower bid-ask spreads (0.01% vs. VOO’s 0.03%) mean it effectively charges half as much in real costs.
Another rival, the SPDR Portfolio S&P 500 ETF (SPLG), charges 0.02% and has even lower trading costs for smaller accounts.
| ETF | Expense Ratio | Avg. Tracking Error (Annual) | Avg. Bid-Ask Spread | Estimated Total Annual Cost |
|---|---|---|---|---|
| VOO | 0.03% | 0.03% | 0.03% | 0.09% |
| IVV | 0.03% | 0.01% | 0.01% | 0.05% |
| SPLG | 0.02% | 0.02% | 0.02% | 0.06% |
3. What $50,000 Looks Like: Compounding the Hidden Cost
Model a $100,000 investment in VOO vs. IVV over 20 years, assuming a 7% annual return from the S&P 500. Using the total cost estimates above (0.09% for VOO vs. 0.05% for IVV), the gap is 0.04% per year.
After 20 years, VOO’s portfolio grows to approximately $386,000. IVV’s grows to $436,000. The difference: $50,000.
This projection aligns with the MSN article “Where will VOO be in 20 years? Here’s what history suggests,” which notes that the S&P 500 has historically returned 7-10% annually, but fees compound to create large gaps over decades.
4. 1 Top Vanguard ETF to Buy Before the Next Market Crash
Despite the hidden costs, VOO remains a solid choice for crash-proofing. Yahoo Finance’s article recommends VOO for its diversification and low volatility during market downturns. During the 2008 crisis, VOO’s liquidity held up better than smaller ETFs. Its brand trust attracts institutional investors, which stabilizes trading during panic.
However, the rival ETF (IVV) performed similarly in bear markets. In 2020, IVV’s tracking error during the crash was actually lower than VOO’s. The liquidity advantage is marginal for retail investors.
5. The 20-Year Forecast: Where Will VOO Be in 2 Decades?
Historical data from MSN suggests the S&P 500 will likely deliver 7-10% annualized returns over the next 20 years, based on long-term averages. But the hidden cost impact is clear: VOO’s net return will trail cheaper ETFs by 0.04% to 0.10% annually.
| Scenario | Initial Investment | Annual Return (Gross) | Total Cost (Annual) | Ending Balance (20 Years) |
|---|---|---|---|---|
| VOO | $100,000 | 7.00% | 0.09% | $386,000 |
| IVV | $100,000 | 7.00% | 0.05% | $436,000 |
| SPLG | $100,000 | 7.00% | 0.06% | $420,000 |
6. How to Avoid the Trap: Actionable Strategies for Investors
Minimize hidden costs with three steps. First, switch to IVV or SPLG for identical S&P 500 exposure at lower total cost. Second, use limit orders instead of market orders to avoid bid-ask spreads during volatility. Third, avoid frequent trading—hold for decades, not months.
For tax-sensitive accounts, consider Schwab’s SWPPX (mutual fund) with a 0.02% expense ratio and no trading costs. VOO’s liquidity advantage matters only for very large trades (over $1 million). For the average investor, it is irrelevant.
