Vanguard and Fidelity are two of the most trusted names in investing, and both offer low-cost ETFs alongside excellent brokerage platforms. The competition between them has been great for investors, driving fees lower and platform quality higher. Here is how their ETF lineups and overall offerings compare.
The Zero-Fee Factor
Fidelity made headlines by launching zero-expense-ratio index mutual funds -- FZROX (US total market) and FZILX (international). These are genuinely free to own: no management fee, no hidden costs. However, these are mutual funds, not ETFs. They track proprietary Fidelity indexes rather than standard benchmarks, and they can only be purchased through Fidelity.
Fidelity's actual ETFs carry low but non-zero expense ratios. For example, FSKAX (the ETF equivalent) is not zero-fee. So while the zero-fee headline is impressive, it applies to a specific set of mutual funds, not the ETF lineup.
Vanguard's lowest-cost ETFs like VTI and VOO charge 0.03%. The practical cost difference between 0.03% and 0.00% on a $100,000 portfolio is $30 per year. Real money, but unlikely to change your financial outcome.
ETF Lineup Comparison
Vanguard offers roughly 80 ETFs that cover every major asset class with broad, diversified exposure. The lineup is intentionally focused -- Vanguard believes most investors are best served by a small number of well-constructed index funds.
Fidelity's ETF lineup is smaller and less established. While Fidelity has been a giant in mutual funds for decades, its ETF business is newer. Products like FTEC (technology), FREL (real estate), and FDIS (consumer discretionary) offer solid sector exposure, but many Fidelity ETFs have significantly smaller assets under management than their Vanguard or iShares equivalents.
Smaller AUM does not necessarily mean worse performance, but it can mean wider bid-ask spreads and less liquidity, particularly for niche products.
Expense Ratios: Side by Side
US Total Market: VTI (0.03%) vs FSKAX (0.015%) -- Fidelity wins
S&P 500: VOO (0.03%) vs FXAIX (0.015%) -- Fidelity wins (mutual fund)
International: VXUS (0.07%) vs FTIHX (0.06%) -- Fidelity wins
US Bond: BND (0.03%) vs FXNAX (0.025%) -- Fidelity wins
Fidelity generally wins on price, though the margins are tiny. These differences add up over decades, but we are talking about single-digit dollars per year on most portfolio sizes. Read our full expense ratio explainer to understand how these small numbers compound.
The Brokerage Experience
This is Fidelity's strongest card. Fidelity's brokerage platform is widely considered best-in-class among discount brokers. Key advantages include:
Research and tools: Fidelity offers robust stock screeners, ETF research, retirement planning calculators, and third-party research from providers like Morningstar.
Fractional shares: You can buy as little as $1 of any ETF or stock on Fidelity, making it easy to invest small amounts regularly.
Customer support: Fidelity consistently ranks at or near the top in customer service surveys, with phone, chat, and branch support.
Mobile app: The Fidelity mobile app is well-designed and full-featured.
Vanguard's platform has improved significantly but is still considered a step behind Fidelity in terms of user experience and features. Many investors choose to buy Vanguard ETFs through Fidelity's platform to get the best of both worlds.
Building a Portfolio
Both providers support the three-fund portfolio strategy and other common approaches:
Vanguard three-fund: VTI + VXUS + BND
Fidelity three-fund (mutual funds): FZROX + FZILX + FXNAX
Fidelity three-fund (ETFs): You would need to use iShares or Vanguard ETFs since Fidelity's ETF lineup does not include a broad total market ETF with the same brand consistency.
One practical note: Fidelity's zero-fee mutual funds cannot be transferred to another brokerage if you ever switch. Vanguard ETFs (and all ETFs) are fully portable -- you can transfer them to any brokerage. For investors who value flexibility, ETFs have an edge over proprietary mutual funds.
Tax Efficiency
Both Vanguard and Fidelity ETFs are tax-efficient thanks to the in-kind creation and redemption process. Vanguard has a patented structure that allows its ETFs to share a share class with a mutual fund, providing an additional tax efficiency edge in some cases.
Fidelity's zero-fee mutual funds do not have this structural advantage and may distribute capital gains in some years, though index mutual funds are generally tax-efficient regardless.
Who Wins for Retirement Accounts?
In tax-advantaged accounts like IRAs and 401(k)s, the tax efficiency advantage disappears. This makes Fidelity's zero-fee mutual funds particularly attractive in these accounts -- you get index exposure at literally no cost, and you do not need to worry about portability since retirement accounts are less frequently transferred.
If your employer's 401(k) is with Fidelity, using Fidelity's zero-fee funds for your retirement accounts and Vanguard ETFs in your taxable brokerage account could be an optimal combination.
The Verdict: Vanguard or Fidelity?
Choose Vanguard if: You want the deepest low-cost ETF lineup, value the mutual ownership structure, and plan to build a portfolio primarily from ETFs. Vanguard's focus and philosophy have earned investor trust for nearly five decades.
Choose Fidelity if: You want the best brokerage platform, value fractional shares and zero-fee mutual fund options, and appreciate top-tier customer service and research tools. Fidelity is the better all-around financial platform.
Best of both: Open a Fidelity brokerage account and buy Vanguard ETFs. Use Fidelity's zero-fee mutual funds in your retirement accounts. This combination gives you Fidelity's superior platform with Vanguard's time-tested ETFs.
