If you have searched for a "Schwab S&P 500 ETF," you are not alone. Thousands of investors ask the same question every month. The problem is that Schwab does not actually offer an ETF that tracks the S&P 500 index directly. The fund that often shows up in those search results, SCHX, is not the same thing.
This matters because investing in the wrong fund could mean you are tracking a broader index than you intended. Here is a clear breakdown of what SCHX is, what SWPPX is, and what to buy if you specifically want an S&P 500 ETF.
What Is SCHX?
SCHX is the Schwab US Large-Cap ETF. It tracks the Dow Jones US Large-Cap Total Stock Market Index and holds approximately 750 of the largest U.S. companies by market capitalization. SCHX is part of the broader Schwab ETF lineup, which spans large-cap, small-cap, international, dividend, and bond funds at similarly low costs.
That is broader than the S&P 500, which holds exactly 500 companies. SCHX includes companies ranked 501 to roughly 750 by market cap that would not qualify for the S&P 500. In practice, the two indexes overlap heavily at the top, since the biggest stocks in both are the same. But they are not identical.
SCHX charges an expense ratio of 0.03% and is commission-free at Schwab. It is a well-constructed, low-cost ETF. It is just not an S&P 500 ETF.
What Is SWPPX?
SWPPX is the Schwab S&P 500 Index Fund. This is Schwab's actual S&P 500 tracking product, but it is a mutual fund, not an ETF.
SWPPX holds the 500 companies that make up the S&P 500 index. Its expense ratio is 0.02% per year, which is lower than most S&P 500 products. There is no minimum investment when you buy it through Schwab. For a comparison of SWPPX alongside FXAIX and VFIAX, the guide to best S&P 500 mutual funds ranks all the major options by expense ratio and accessibility.
The catch: because it is a mutual fund, SWPPX prices once per day at NAV. You cannot trade it intraday like an ETF. Orders placed during the day are executed at the closing price.
The Source of the Confusion
The confusion likely comes from two places. First, SCHX sounds like it could be an S&P 500 ETF based on its name and Schwab branding. Second, SCHX's top holdings look almost identical to the S&P 500 because the largest 500 companies dominate both indexes.
But index construction matters. The S&P 500 is maintained by a committee that applies specific eligibility rules, including profitability requirements. SCHX's index uses a simpler market-cap cutoff. Companies that fail the S&P 500's profitability screen can still appear in SCHX.
True S&P 500 ETF Options
If you want a pure S&P 500 ETF, not a mutual fund and not a broader large-cap ETF, you need to look outside Schwab's ETF lineup. The most popular options are:
- VOO (Vanguard S&P 500 ETF): 0.03% expense ratio, highly liquid, excellent tracking
- IVV (iShares Core S&P 500 ETF): 0.03% expense ratio, similar to VOO
- SPY (SPDR S&P 500 ETF Trust): 0.0945% expense ratio, the oldest and most traded S&P 500 ETF
All three are available commission-free on most major brokers and track the S&P 500 directly. For long-term investors, VOO and IVV are generally preferred over SPY due to lower costs. A dedicated SPY vs VOO comparison breaks down liquidity, cost, and which one suits buy-and-hold investors.

Which One Should You Buy?
If your goal is to track the S&P 500 specifically:
- For an ETF: Buy VOO or IVV. These are the most popular and cheapest S&P 500 ETFs.
- For a mutual fund: SWPPX is your best option within Schwab. Its 0.02% expense ratio is among the lowest available.
- For general large-cap exposure: SCHX works well and is marginally cheaper than VOO per dollar invested.
Schwab also offers SWTSX, its Schwab total market fund, for investors who want coverage beyond the S&P 500's 500 companies. When choosing a broker for your S&P 500 investment, a comparison of Fidelity vs Schwab can help you decide which platform better fits your needs.
To access any of these options, you will need a brokerage account. One option worth considering is Robinhood, which offers commission-free trading on ETFs including VOO and SCHX, along with fractional shares so you can invest any dollar amount. Robinhood also offers IRA accounts with a 1% contribution match.
Note that SWPPX is a Schwab mutual fund and is typically only available through a Schwab account.
Investing involves risk. You can lose money, including your initial investment. Consider your goals, time horizon, and risk tolerance before investing.

Common Scenarios
"I want the S&P 500 in ETF form at the lowest cost." Buy VOO (0.03%) or IVV (0.03%). Both are true S&P 500 ETFs with very low costs and high liquidity.
"I want the S&P 500 and I have a Schwab account." Buy SWPPX (0.02%), Schwab's mutual fund that tracks the S&P 500. It is the cheapest true S&P 500 product Schwab offers.
"I want broad U.S. large-cap exposure and I am not set on the S&P 500 specifically." SCHX (0.03%) is a solid choice. Its slightly broader index covers about 750 companies and overlaps heavily with the S&P 500 at the top.
"I want to invest small amounts regularly." SWPPX has no minimum and accepts any dollar amount. For ETFs, use a broker with fractional share support like Robinhood.

Does the Index Difference Actually Matter?
For most long-term investors, the performance difference between SCHX and a pure S&P 500 fund is very small. The extra 250 companies in SCHX are small enough that they barely move the needle on total returns.
Over rolling 10-year periods, SCHX and VOO have performed similarly. The bigger factor in your long-term returns is whether you invest consistently and avoid trying to time the market, not whether you hold 500 or 750 stocks.
That said, clarity matters. If someone asks what index your portfolio tracks and you want to say "the S&P 500," you need VOO, IVV, SPY, or SWPPX, not SCHX.
Frequently Asked Questions
Does Schwab have an S&P 500 ETF?
No. Schwab does not currently offer an ETF that tracks the S&P 500 specifically. SCHX, which is often mistaken for an S&P 500 ETF, actually tracks the Dow Jones US Large-Cap index with about 750 holdings. Schwab's S&P 500 product is SWPPX, which is a mutual fund.
What is the difference between SCHX and VOO?
SCHX tracks the Dow Jones US Large-Cap index with approximately 750 holdings. VOO tracks the S&P 500 with exactly 500 holdings. Both charge 0.03% per year. They perform similarly over time because the largest 500 companies dominate both indexes, but they are not the same fund tracking the same index.
Is SWPPX better than VOO?
SWPPX has a slightly lower expense ratio (0.02% vs 0.03%) and tracks the same S&P 500 index. For investors at Schwab, SWPPX is slightly cheaper. The downside is that SWPPX is a mutual fund that prices once daily, while VOO trades intraday. In a tax-advantaged account where tax efficiency does not matter, SWPPX wins on cost. In a taxable account, VOO's ETF structure may have a slight edge on tax efficiency.
Can I buy VOO or IVV on Robinhood?
Yes. VOO, IVV, and SPY are all available commission-free on Robinhood. Robinhood supports fractional shares on these ETFs, so you can invest any amount starting at $1 rather than having to buy a full share.
