Schwab Index Funds: Low-Cost Investing Made Easy
Schwab built one of the cheapest index lineups in the business, often with no minimum at all. Here's how SWPPX, SWTSX and the Schwab ETFs stack up — and where Schwab fits next to Vanguard and Fidelity.
Don't have time? Here's what you need to know:
- 1Schwab's index funds are among the cheapest anywhere — SWPPX (S&P 500) and SWTSX (total market) at roughly 0.02%-0.03% with no minimum.
- 2Schwab's broad ETFs SCHB and SCHX match Vanguard's ultra-low costs; SCHD is its popular dividend ETF.
- 3Vanguard, Fidelity, and Schwab now offer index funds so similar in cost that provider choice barely affects your return.
- 4No-minimum mutual funds make Schwab a strong fit for beginners automating small monthly contributions.
Schwab's Low-Cost Index Lineup
Charles Schwab competes hard on price, and its index funds are among the cheapest available anywhere. SWPPX tracks the S&P 500 at roughly 0.02%, and SWTSX tracks the total U.S. stock market at a similarly low cost. Both are index mutual funds with no investment minimum at Schwab, so you can start with whatever you have — a feature that historically set Schwab apart from competitors that required a few thousand dollars to buy their cheapest funds.
On the ETF side, Schwab offers an equally cheap lineup. SCHB covers the broad U.S. market, SCHX covers large-caps, and SCHD is its popular dividend-focused ETF. Schwab's broad-market ETFs carry expense ratios in the same ultra-low range as Vanguard's, so whether you prefer mutual funds or ETFs, Schwab gives you a full low-cost toolkit under one roof.
The Funds Side by Side
Schwab's core index funds map cleanly onto the same exposures you would build with Vanguard or Fidelity. The table below shows the main mutual funds and ETFs for U.S. equity. As always, the funds inside a category track essentially the same companies, so the choice between, say, SWPPX and SCHX is mostly mutual-fund-versus-ETF rather than a difference in what you own.
| Fund | Type | Exposure | Approx. expense ratio |
|---|---|---|---|
| SWPPX | Mutual fund | S&P 500 | ~0.02% |
| SWTSX | Mutual fund | Total U.S. market | ~0.03% |
| SCHB | ETF | Broad U.S. market | ~0.03% |
| SCHX | ETF | U.S. large-cap | ~0.03% |
| SCHD | ETF | U.S. dividend stocks | ~0.06% |
Tip: Schwab's index mutual funds have no minimum investment, so they're a good fit for a beginner who wants to start with a small, fixed monthly amount rather than buying whole shares.
Where Schwab Fits Next to Vanguard and Fidelity
The honest truth is that Vanguard, Fidelity, and Schwab now offer index funds so similar in cost and quality that the differences are minor for a long-term investor. All three run S&P 500 and total-market index funds in the 0.00% to 0.03% range. You are not going to meaningfully change your outcome by picking one provider's 0.02% fund over another's 0.03% fund — the index inside is what drives your return.
Schwab's particular strengths are its polished trading platform, strong customer service, and a banking arm that pairs well with brokerage accounts. Its dividend ETF SCHD has also attracted a large following among income-focused investors. If you already bank or trade with Schwab, building your index portfolio there with SWPPX or SCHB is an excellent, frictionless choice.

Building a Simple Schwab Portfolio
A complete index portfolio at Schwab is easy to assemble. For the equity core, use SWTSX or SCHB for the total U.S. market, or SWPPX for the S&P 500. Add Schwab's international index fund or ETF for non-U.S. exposure, and a Schwab bond index fund or a broad bond ETF like BND for stability. That gives you a three-part portfolio of U.S. stocks, international stocks, and bonds — all low-cost and all in one account.
From there the strategy is the same as with any index portfolio: contribute regularly, keep your asset allocation steady, and rebalance occasionally. Schwab's no-minimum mutual funds make automatic monthly investing straightforward, which is the single most reliable habit for building wealth with index funds over time.
Frequently Asked Questions
Is Schwab good for index fund investing?
Yes. Schwab offers some of the cheapest index funds available — SWPPX tracks the S&P 500 at about 0.02% and SWTSX the total market at a similarly low cost, both with no minimum investment. Its broad-market ETFs like SCHB and SCHX are just as cheap. For a low-cost index investor, Schwab is on par with Vanguard and Fidelity.
What's the difference between SWPPX and SCHX?
SWPPX is an S&P 500 index mutual fund; SCHX is a large-cap ETF. They cover very similar large-cap U.S. exposure at nearly identical low costs. The practical difference is the wrapper — SWPPX lets you invest a fixed dollar amount with no minimum and automate it easily, while SCHX trades intraday like a stock and tends to be marginally more tax-efficient in taxable accounts.
Should I choose Schwab, Vanguard, or Fidelity?
For index funds, the three are close enough that it rarely matters — all offer S&P 500 and total-market funds in the 0.00%-0.03% range. Pick based on the wider experience: Fidelity has its 0.00% ZERO funds, Vanguard pioneered indexing with a low-cost culture, and Schwab pairs a polished platform with banking. The best choice is usually whichever you already use.
