Schwab's Ultra-Cheap House ETFs
Charles Schwab built one of the most cost-competitive ETF lineups in the business, often undercutting rivals by a hair on the broadest funds. Its core equity ETFs — SCHB for the total U.S. market, SCHX for U.S. large caps, and SCHF for developed international stocks — carry expense ratios around 0.03% to 0.06%, right at the industry floor. Schwab also offers $0 commissions and fractional shares of S&P 500 stocks.
On the dividend side, SCHD has become one of the most popular dividend-focused ETFs available, screening for quality companies with sustained dividend growth at a low cost. The point is that a Schwab investor can assemble a complete, globally diversified passive portfolio entirely from cheap house-brand funds — or mix in any third-party ETF commission-free. The platform doesn't lock you in.
A Complete Portfolio From Schwab Funds
Building a three-fund portfolio entirely from Schwab ETFs is straightforward. The table below shows a representative lineup covering U.S. stocks, international stocks, and bonds — the three pillars of a globally diversified passive portfolio — all at rock-bottom expense ratios. You can adjust the weights to your risk tolerance, but the holdings stay this simple.
Because every fund here trades commission-free and supports fractional investing, you can fund the whole portfolio with a modest recurring contribution and keep the target proportions intact. There's nothing exotic about it, which is exactly the point: low cost, broad diversification, and a structure you can leave alone for decades.
| Sleeve | Schwab ETF | What it covers | Approx. expense ratio |
|---|---|---|---|
| U.S. stocks | SCHB | Total U.S. stock market | ~0.03% |
| U.S. large caps (alt.) | SCHX | U.S. large-cap stocks | ~0.03% |
| International stocks | SCHF | Developed markets ex-U.S. | ~0.06% |
| U.S. bonds | SCHZ | Broad U.S. bond market | ~0.03% |
| Dividend tilt (optional) | SCHD | Quality dividend-growth stocks | ~0.06% |
Tip: SCHB and SCHX overlap heavily — pick one as your U.S. core rather than holding both. SCHD is an optional dividend tilt, not a replacement for a broad-market fund.
The Robo-Advisor and Its Cash Catch
Schwab's robo-advisor builds and rebalances a diversified ETF portfolio for you with no advisory fee, which sounds ideal for a hands-off passive investor. The catch is in how it's funded: the service requires holding a meaningful slice of the portfolio in cash, and that cash sits in a Schwab-affiliated account where the firm earns the spread. The 'free' service is effectively paid for through that cash allocation.
For a long-term investor, a forced cash position is a real drag, because cash has historically returned far less than a diversified stock-and-bond portfolio. A double-digit cash allocation in a growth-oriented account can quietly cost meaningful return over decades. None of this makes the robo unusable — it can be fine for someone who genuinely wants zero involvement — but a do-it-yourself portfolio of the same Schwab ETFs avoids the cash drag entirely and is barely more work.
Important: Schwab's robo holds a required cash allocation that funds the 'free' service. For a long-horizon investor, that idle cash can drag on returns; a DIY ETF portfolio avoids it.

Putting It on Autopilot
Whichever route you take, automation is what makes passive investing at Schwab work. You can schedule recurring transfers from your bank and recurring purchases of your chosen ETFs, turning the strategy into hands-off dollar-cost averaging. With fractional shares and $0 commissions, even small contributions get fully invested.
The combination that serves most passive investors best at Schwab is a self-managed portfolio of two to four cheap house ETFs, funded by automatic monthly contributions, held in a tax-advantaged account where possible. It captures Schwab's genuinely low costs without paying the implicit price of the robo's cash allocation. Our portfolio-building guide covers how to choose your weights.
Frequently Asked Questions
Which Schwab ETFs make a good passive portfolio?
A simple three-fund setup uses SCHB (total U.S. market) or SCHX (U.S. large caps) for domestic stocks, SCHF for developed international, and SCHZ for bonds — all around 0.03% to 0.06%. SCHD is a popular optional dividend tilt. Pick one U.S. core rather than holding overlapping funds, and weight the sleeves to your risk tolerance.
Is Schwab's robo-advisor really free?
There's no stated advisory fee, but it isn't truly free. The service requires holding a meaningful cash allocation in a Schwab-affiliated account where the firm earns the spread — that's how the 'free' service is funded. For a long-term investor, a forced double-digit cash position can drag on returns, so a DIY ETF portfolio of the same funds is often better.
What's the difference between SCHB and SCHX?
SCHB tracks essentially the entire U.S. stock market, including small and mid caps, while SCHX covers only U.S. large caps. They overlap heavily because large caps dominate the market, so you'd typically hold one as your U.S. core, not both. SCHB is slightly broader; SCHX is a cleaner large-cap play. Both cost around 0.03%.
Can I hold non-Schwab ETFs in a Schwab account?
Yes. Schwab offers $0 commissions on U.S.-listed ETFs across the board, so you can mix house-brand funds like SCHB with third-party ETFs such as VTI, VXUS, or BND without extra cost. The platform doesn't lock you into its own products, which makes it a flexible home for a passive portfolio.
