Fidelity vs Vanguard 2026: The Brokerage Comparison That Actually Matters

Side-by-Side Comparison

Verified May 13, 2026 against fidelity.com and vanguard.com.

Which has lower fund expenses?

Fidelity, by a small margin. The headline difference is Fidelity's ZERO line of index mutual funds:

On a $500,000 portfolio invested in total market funds:

• FZROX: $0/year in expense ratio costs
• VTI: $150/year (at 0.03%)
• VTSAX: $200/year (at 0.04%)

The dollar difference is real but small. The bigger consideration is portability: VTI is an ETF and can be transferred to any brokerage in-kind. FZROX is a Fidelity-only mutual fund — to leave Fidelity, you'd need to sell it first, potentially triggering capital gains taxes in taxable accounts. For investors committed to Fidelity long-term, FZROX is slightly cheaper. For investors who value optionality, VTI is more flexible.

Why does Vanguard's cash sweep matter?

Default cash sweep rates are an often-overlooked yield differential. When you sell a stock at Fidelity or Vanguard, the proceeds sit in a default money market fund until you reinvest or withdraw. The default sweep rate matters because:

1. Active investors hold cash between trades — often days to weeks
2. Dividend-receiving accounts accumulate cash before reinvestment
3. Retirees hold cash buffers for upcoming distributions
4. Settled cash awaiting deployment can sit for months

Current default sweep yields:

• Vanguard VMFXX (Federal Money Market Fund): ~4.50%
• Fidelity SPAXX (Government Money Market Fund): ~2.62%

On a $50,000 cash balance held for one year, the difference is roughly $940 in interest. Over time and across multiple cash holdings, this compounds.

Workaround at Fidelity: investors can manually move cash to FDRXX (Fidelity Government Cash Reserves, ~4.30%) or FZFXX (Fidelity Treasury Money Market) for higher yields. But this requires deliberate action — by default, you're earning much less.

For investors who passively hold cash, Vanguard's default sweep is meaningfully better.

Which is better for retirement accounts?

Fidelity, decisively, for the breadth of account types and features:

Fidelity offers:

• Traditional and Roth IRA
• Rollover IRA
• Inherited IRA
• SEP IRA
• Solo 401(k) — with Roth contribution option (rare among brokerages)
• HSA with full investment access (including FZROX)
• 529 college savings plans (NH, MA, AZ, DE)
• Fidelity Youth Account (ages 13-17, fractional trading)
• Custodial accounts (UGMA/UTMA)

Vanguard offers:

• Traditional and Roth IRA
• Rollover IRA
• SEP IRA
• SIMPLE IRA
• 529 savings (Nevada)
• Custodial accounts
• Not offered: Solo 401(k), HSA, Youth Account, Inherited IRA (limited)

For self-employed individuals, the Solo 401(k) with Roth option at Fidelity is unique among major brokerages. Vanguard doesn't offer Solo 401(k) at all — self-employed Vanguard investors typically use SEP IRA, which has lower contribution limits and no Roth option.

For HSA users (high-deductible health plan participants), Fidelity is one of the best HSAs available — no fees, no minimums, and full investment options including the zero-expense-ratio funds. Vanguard doesn't offer HSAs.

Which has the better mobile app?

Fidelity, by significant margin. The Fidelity app:

• 4.8 stars on iOS (best-rated brokerage app)
• Fast, modern UI
• Fractional share trading from $1
• Cash Management Account features (debit card, bill pay, ATM rebates)
• Robust research and screening tools
• Active Trader Pro available for advanced users

The Vanguard app:

• 4.5 stars on iOS (functional but dated)
• Slower navigation
• Limited research tools on mobile
• Better suited for occasional check-ins than active management
• Vanguard has been incrementally modernizing the app, but pace has been slow

For investors who do most of their account management on mobile, Fidelity's app is the practical winner.

What about Vanguard's client-owned philosophy?

Vanguard's structure is structurally different from every other major brokerage. Vanguard is owned by its mutual funds, which in turn are owned by the fund shareholders. There is no external owner extracting profits — operating costs are returned to fund shareholders as lower expense ratios.

This is the structural reason Vanguard pioneered ultra-low-cost index investing under founder Jack Bogle. The structure has produced:

• Industry-leading low expense ratios across the fund lineup
• Long-term-shareholder-aligned governance
• Lack of pressure to push higher-margin products to clients

The structural advantage has compressed over time as competitors (Fidelity, Schwab, BlackRock/iShares) have matched or undercut Vanguard's expense ratios. Today, FZROX at 0.00% slightly undercuts VTI at 0.03%.

For long-term index investors who philosophically prefer Vanguard's structure even at a marginal cost, the choice is values-driven. The pure dollars argument is weaker than it was 15 years ago.

When does Vanguard win?

Three specific scenarios:

1. You already have significant positions in VTSAX/VTI/VTIAX. Don't move funds just to chase 0.03% in expense ratio savings. The transition cost (taxes on sales in taxable accounts, time, complexity) almost always exceeds the lifetime savings.

2. You're a pure buy-and-hold investor who never trades and never visits branches. Vanguard's dated app and lack of branches don't matter if you check your account once a year.

3. You hold significant cash awaiting deployment. Vanguard's 4.50% default cash sweep beats Fidelity's 2.62% default — and you'd have to manually optimize at Fidelity to match.

Choose Fidelity if...

• You're opening your first brokerage account
• You want the best mobile experience
• You need an HSA, Solo 401(k), or Youth Account
• You may want occasional in-person support
• You value zero-expense-ratio funds and aren't planning to leave Fidelity

Choose Vanguard if...

• You already have established positions in Vanguard funds
• You're a pure buy-and-hold index investor
• You hold significant cash and want the higher default sweep rate
• You philosophically value the client-owned structure
• You don't need premium service or modern app features

Use both if...

Some investors keep both accounts:

• Fidelity for active accounts (taxable brokerage, HSA, Roth IRA, Solo 401(k))
• Vanguard for legacy positions in VTSAX/VTI/VBIAX (never move what you've already built)

This works well if you've inherited Vanguard positions or built them years ago. There's no need to consolidate — both are excellent custodians.
