Charles Schwab and Fidelity are the two largest full-service brokerages in the US. Both charge zero commissions, offer extensive fund lineups, integrate banking, and run their own robo-advisors. The real differences are subtle but meaningful: cash sweep yields, fund minimums, robo fees, and the feel of the apps. Here's the 2026 head-to-head.
Quick Verdict
- Choose Schwab if you want top-tier banking integration, the best research tools, and prefer a thinkorswim-style trading platform.
- Choose Fidelity if you want zero-fee index funds, the highest cash sweep yield by default, and the best mobile app.
Fees & Commissions
Both offer $0 commissions on stocks, ETFs, and most mutual funds. Both offer fractional shares. Both offer comprehensive options trading. On the surface, this is a tie.
Index Fund Costs
Fidelity wins on headline expense ratios with its ZERO funds (0.00%). Schwab's flagship index funds — SWTSX (Total Market) and SWPPX (S&P 500) — charge a still-tiny 0.03%. On a $100,000 portfolio that's a $30 difference per year. Schwab funds, however, are portable to any brokerage; Fidelity ZERO funds are not.
Cash Sweep & Money Market
This is the biggest difference between the two. Fidelity automatically sweeps uninvested cash into SPAXX, paying a competitive 4%+ yield in 2026 with no action required. Schwab's default cash sweep pays a notoriously low yield (under 0.5%) — you must manually move cash into a money market fund or T-bill to earn meaningful interest. For passive investors this is a real, ongoing drag at Schwab. Edge: Fidelity.
Banking Integration
Schwab Bank is widely regarded as one of the best in the US — high-yield checking, debit card with unlimited ATM fee rebates worldwide, no foreign transaction fees. Fidelity's Cash Management Account (CMA) offers similar features but with slightly thinner perks. For frequent travellers, Schwab wins on banking.
Robo-Advisor Comparison
- Schwab Intelligent Portfolios: 0% management fee but holds 6–30% in Schwab cash earning low yield (an opportunity-cost drag).
- Fidelity Go: Free under $25,000, 0.35%/year above. No cash drag.
Both are reasonable. See our best US robo-advisors guide for the broader comparison.
Trading Platforms
Schwab acquired thinkorswim from TD Ameritrade and now offers it as their advanced platform — arguably the best charting and options platform in the industry. Fidelity's Active Trader Pro is excellent but a step behind thinkorswim for serious technical traders. Edge: Schwab for active traders.
Mobile App
Fidelity's mobile app consistently ranks at or near the top of brokerage app reviews — clean, fast, well-designed. Schwab's app is functional but feels older. Edge: Fidelity.
Customer Service
Both are excellent — phones answered fast, US-based reps, branch networks. Schwab arguably has the larger physical branch presence; Fidelity edges ahead in independent service surveys. Effectively a tie for most users.

Which Should You Pick?
For most long-term investors, Fidelity is the slightly better default — the auto-sweep alone could save you hundreds per year on idle cash. For active traders, frequent international travellers, or those who value the Schwab Bank ecosystem, Schwab is the better all-round choice. Many savvy investors actually use both: Schwab for banking and active trading, Fidelity for IRAs and long-term holdings.
