Fidelity vs Schwab vs Vanguard: Which Broker Wins
Key Takeaways
- Schwab's default cash sweep pays 0.45% versus 3.49-3.55% at Fidelity and Vanguard — the largest cost difference between the three brokers
- Index fund expense ratios are functionally identical: 0.00% (Fidelity) to 0.04% (Vanguard) — a $40 annual difference on $100,000
- Schwab's thinkorswim platform is best for active traders, Fidelity wins on research breadth, Vanguard wins on structural cost alignment
- The worst decision is delaying investing while comparing brokers — all three are excellent for long-term wealth building
Three brokers control the majority of US retail investment assets. Fidelity manages $14.1 trillion in customer assets. Schwab, post-TD Ameritrade merger, manages $10.8 trillion. Vanguard oversees $9+ trillion. All three offer commission-free stock and ETF trading, low-cost index funds, and robust retirement account options.
The differences that matter are not in the headline features but in the fine print: cash sweep yields, money market rates, options pricing, platform quality, and how each firm actually makes money from your account. Your optimal broker depends entirely on how you invest.
The Cash Yield Problem
With the Fed funds rate at 3.64%, where your uninvested cash sits matters enormously. This is where the three brokers diverge most sharply.
Schwab's default cash sweep pays roughly 0.45% — a full 3 percentage points below the Fed funds rate. On $50,000 in cash, that costs you $1,500 per year versus a market-rate money market fund. Schwab offers higher-yielding alternatives (SWVXX at ~3.5%), but you must actively opt in. Most investors never do. This is not an accident — net interest income from client cash balances generates over 60% of Schwab's revenue.
Fidelity's SPAXX money market fund yields 3.49% and serves as the default sweep for brokerage accounts. Vanguard's VMFXX yields 3.55%. Both are close to fair value given current rates.
This single difference — Schwab's low default sweep versus Fidelity and Vanguard's competitive rates — is the most consequential factor for investors holding any meaningful cash position.
Index Fund Costs: A Race Already Won
Expense ratio comparison at the index fund level is effectively over. The differences are measured in hundredths of a percent.
Fidelity's FZROX (total US market) charges 0.00%. Literally zero. Schwab's SWTSX charges 0.03%. Vanguard's VTSAX charges 0.04% (or VTI at 0.03%). On a $100,000 portfolio, the annual cost difference between Fidelity's zero and Vanguard's 0.04% is $40. That is not a rounding error — it is the error.
The more meaningful comparison is across the full fund lineup. Vanguard's average expense ratio is 0.08%. Fidelity's actively managed funds average significantly higher. Schwab falls between the two. For an investor using only index products, all three are functionally equivalent.
The real cost differences emerge in advisory services. Vanguard Personal Advisor charges 0.30% annually. Schwab Intelligent Portfolios Premium charges $30/month (roughly 0.12% on a $300,000 account). Fidelity Go charges 0.35% for managed portfolios over $25,000. For investors who want human guidance, Schwab's flat-fee model is cheapest above $300,000.
Platform and Tools
Schwab inherited TD Ameritrade's thinkorswim platform, which remains the best retail trading platform available. Advanced charting, customisable screeners, paper trading, and sophisticated options analysis tools make it the clear winner for active traders. No other retail platform comes close.
Fidelity's Active Trader Pro is solid — fast execution, good research integration, and a mobile app that balances functionality with usability. Fidelity also offers the best equity research access, including 20+ third-party research providers at no additional cost.
Vanguard's platform is deliberately minimalist. It serves the needs of buy-and-hold investors competently but offers nothing for traders. Recent updates improved mobile functionality, but the web experience still feels a generation behind. Vanguard views this as a feature: a boring platform discourages the excessive trading that destroys returns.
For customer service, Fidelity consistently ranks first in J.D. Power surveys. Schwab's service quality dipped during the TD Ameritrade integration but has recovered. Vanguard's service has improved but remains the weakest of the three.
The Right Broker for Your Profile
Passive index investor saving for retirement: Vanguard. The mutual ownership structure guarantees fees stay low long-term, target-date funds are best in class at 0.08%, and the platform's simplicity reduces the temptation to tinker. If you plan to own three funds for 30 years, Vanguard's minimalism is a feature.
Active trader or options investor: Schwab. Thinkorswim has no peer in retail trading platforms. Options contracts cost $0.65 each at all three brokers, but Schwab's tools for analysis, backtesting, and execution are meaningfully superior. Just move your cash out of the default sweep.
All-in-one investor wanting research and breadth: Fidelity. Best research access, zero-fee index funds, competitive cash yields, a strong mobile app, and fractional share trading down to $1. Fidelity is the most complete package for investors who want quality across every dimension.
High cash balance or bank-broker integration: Fidelity or Vanguard. Schwab's low default sweep yield makes it a poor choice for investors holding significant cash. If you insist on Schwab, immediately switch to SWVXX or move cash to a high-yield savings account.
All three are excellent. The worst choice is not picking the wrong one — it is spending so long comparing that you delay investing. With the S&P 500 at $659 per SPY share and 10-year Treasuries at 4.26%, the cost of sitting on the sideline exceeds the cost of any fee difference between these three firms.
Conclusion
Fidelity wins on breadth and research. Schwab wins on trading tools. Vanguard wins on structural cost alignment. None of these advantages are large enough to justify switching from one to another if you already have an established account.
The decision that matters most is not which broker to choose but whether your cash is earning a competitive yield and your investment approach is consistent. At today's 3.64% Fed funds rate, the gap between Schwab's 0.45% default sweep and Vanguard's 3.55% money market fund dwarfs any expense ratio difference across index funds. Fix the cash problem first.
