Fidelity vs Charles Schwab vs Vanguard US 2026: Brokerage Three-Way

Updated: September 2026.

TL;DR verdict

For most US long-term investors in 2026, Fidelity Investments is the strongest all-round brokerage because the ZERO expense ratio index funds, the industry-competitive cash sweep, the deep IRA and workplace retirement integration, and full fractional share support on stocks and ETFs are all best in class or tied for best. Charles Schwab is the tightest runner-up with a comparable ETF lineup, integrated banking, and a slightly stronger check writing and debit experience. Vanguard remains the philosophical choice for a mutual-fund-first investor who values the client-owned corporate structure and the deep Admiral Shares lineup, though the platform lags Fidelity and Schwab on user experience and cash sweep default. All three are SIPC members and appropriate for long-term compounding.

The three brokerages in 2026

Fidelity Investments manages $14.1 trillion in assets under administration per the Fidelity Q2 2025 shareholder update, making it the largest US retail brokerage. Fidelity states on its overview page: "Fidelity is the largest privately held financial services company in the world, serving 51 million individual investors" (fidelity.com/why-fidelity/overview). Charles Schwab, after the TD Ameritrade integration completed in 2023, reported $10.5 trillion in client assets per the Schwab Q4 2024 earnings release: "As of December 31, 2024, Schwab's total client assets reached $10.5 trillion, up 21 percent year over year" (aboutschwab.com Q4 2024 press release, January 2025). Vanguard, the pioneer of the index fund category since 1975 and structured as a mutual investor-owned firm, managed $9.3 trillion in assets under management per Vanguard 2024 annual disclosures: "Vanguard's global assets under management stood at $9.3 trillion at year-end 2024" (vanguard.com corporate news, February 2025).

All three are FINRA-regulated broker-dealers and SIPC members. The Securities Investor Protection Corporation states: "SIPC protects customers if their brokerage firm fails, up to $500,000 per customer including a $250,000 limit for cash" (sipc.org/for-investors/introduction). This coverage is identical at all three firms and applies on top of firm-specific excess coverage which all three carry.

Trading commissions and headline fees

The three converged on the same headline pricing after the 2019 zero-commission move:

• $0 commission on US-listed stock, ETF, and options trades (options carry $0.65 per contract at all three).
• $0 account minimum on standard taxable brokerage accounts.
• $0 IRA maintenance fee at all three.

The differentiation is no longer at the commission line. It is at the expense ratio, cash sweep, and margin rate.

Expense ratios on core index funds

This is the biggest cost line item over a 30 year holding period.

Fund	Ticker	Expense ratio
Fidelity ZERO Total Market Index Fund	FZROX	0.00%
Fidelity ZERO Large Cap Index Fund	FNILX	0.00%
Vanguard Total Stock Market ETF	VTI	0.03%
Vanguard S&P 500 ETF	VOO	0.03%
Schwab Total Stock Market Index Fund	SWTSX	0.03%
Schwab US Broad Market ETF	SCHB	0.03%
iShares Core S&P 500 ETF (available all three)	IVV	0.03%

Fidelity ZERO funds are only held inside Fidelity accounts (they are not portable to Schwab or Vanguard if you transfer). VTI and VOO are ETFs so they trade and transfer normally at all three brokerages.

Practical implication: on a $100,000 portfolio held 30 years at 8 percent nominal returns, the difference between a 0.00 percent and a 0.03 percent expense ratio is roughly $2,700 over the full period. Meaningful but not decisive at this scale.

Cash sweep and idle cash

This is the single biggest ongoing fee difference in 2026 and where Schwab has been criticised by the SEC.

Fidelity defaults uninvested cash into the Fidelity Government Money Market Fund (SPAXX) which yields close to the fed funds rate, published daily at fidelity.com. The default sweep is a money market fund yielding materially higher than a bank sweep.

Schwab defaults uninvested cash into Schwab Bank Deposit, a low-yield bank sweep. To earn a higher yield, Schwab customers must actively move cash into Schwab Value Advantage Money Fund (SWVXX) or the Schwab money market ETF alternative. SEC settled with Schwab in June 2022 for $187 million for undisclosed conflicts related to Schwab Intelligent Portfolios cash allocations, per the SEC press release: "Charles Schwab paid $187 million to settle SEC charges related to allocations to cash in its robo-adviser product" (sec.gov/news/press-release/2022-104, June 13, 2022).

Vanguard defaults uninvested cash into the Vanguard Federal Money Market Fund (VMFXX) which typically yields close to the fed funds rate, similar to Fidelity's default. Historically the strongest default sweep.

If you hold significant idle cash in a brokerage, Fidelity or Vanguard default is materially better than Schwab default. Actively swept Schwab cash into SWVXX closes the gap.

Fractional shares

Fidelity supports fractional share trading on stocks and ETFs (Stocks by the Slice, launched January 2020) with minimum trade size of $1. Schwab supports fractional shares on stocks in the S&P 500 only (Schwab Stock Slices), which is more limited. Vanguard does not support fractional shares on stocks or ETFs; you can only buy fractional shares of Vanguard mutual funds.

If you dollar-cost average into individual stocks or ETFs like VTI or QQQ, Fidelity is materially the better platform.

IRA and 401(k) rollover

All three firms accept Traditional IRA, Roth IRA, SEP IRA, Solo 401(k), and rollovers from workplace 401(k) plans. Fidelity is the largest workplace 401(k) recordkeeper in the US, which makes in-place rollover from a Fidelity-recordkept employer 401(k) into a Fidelity Rollover IRA the frictionless path (no paperwork, no wire transfer, keep the account under one login).

If your employer 401(k) is at Schwab or Vanguard, the same logic applies to those brokerages.

Fund lineup breadth

• Fidelity: Fidelity ZERO funds (proprietary, zero-expense-ratio, non-portable), full lineup of Fidelity active and index mutual funds, all major third-party ETFs, foreign markets on Fidelity International trading platform.
• Schwab: Schwab OneSource no-transaction-fee mutual fund network is the largest, Schwab own ETFs (SCHB, SCHX, SCHD) at low expense ratios, full third-party ETF access, integrated Schwab Bank checking and Schwab Charitable donor-advised fund.
• Vanguard: Vanguard mutual funds and ETFs are the flagship (VOO, VTI, VXUS, BND). Third-party fund and ETF access is available but Vanguard's own products are the reason to be there.

Verdict by user type

• New investor starting a Roth IRA with $100 a month contribution: Fidelity. Fractional shares, zero expense ratio ZERO funds, or VTI at $0 commission.
• Investor who wants a brokerage plus daily checking under one login: Schwab. The Schwab Bank integration is the strongest of the three.
• Buy and hold index investor who cares most about corporate structure and low costs on core index products: Vanguard. VTI, VOO, VXUS, BND. Accept the interface trade-off.
• Investor rolling over a large 401(k): whichever firm your employer used, unless the fund lineup is materially worse. Otherwise Fidelity or Vanguard for the sweep default.
• Investor with significant idle cash in a brokerage sweep: Fidelity or Vanguard, not Schwab default.

Where this does not apply

Skip all three for active options trading and complex derivatives. Interactive Brokers, tastytrade, and thinkorswim (now under Schwab, but the platform is preserved) are stronger. Skip all three for crypto trading; use Coinbase, Kraken, or Fidelity Crypto for spot crypto exposure.

For international investors outside the US, none of the three offers the same account structure; Interactive Brokers is typically the fit there. For self-directed alternative asset exposure (private equity, real estate, direct-lending funds), consider IRA custodians that support alternative assets (Alto IRA, Rocket Dollar).

Frequently asked questions

Which is the best brokerage account for US investors in 2026?

Fidelity Investments is the best all-round brokerage for most US investors in 2026 with zero expense ratio ZERO index funds, a high-yield money market default sweep, full fractional share support, and deep IRA and workplace retirement integration. Charles Schwab is the closest runner-up. Vanguard remains philosophically strong for a mutual-fund-first investor.

Are Fidelity ZERO funds actually zero expense ratio?

Yes, the Fidelity ZERO Total Market Index Fund (FZROX), ZERO Large Cap Index Fund (FNILX), ZERO Extended Market Index Fund (FZIPX), and ZERO International Index Fund (FZILX) all have a stated 0.00 percent expense ratio. Fidelity subsidises the operating cost internally. The trade-off is these funds are proprietary to Fidelity accounts and cannot be transferred out in-kind if you move brokerages.

Which brokerage has the best cash sweep in 2026?

Fidelity and Vanguard have the strongest default cash sweep, defaulting uninvested cash into their government money market funds (SPAXX at Fidelity, VMFXX at Vanguard) which yield close to the fed funds rate. Charles Schwab defaults to a low-yield bank sweep and requires active movement into SWVXX to earn competitive yield.

Do all three brokerages have SIPC protection?

Yes, Fidelity, Charles Schwab, and Vanguard are all SIPC members. SIPC protects customer assets up to $500,000 per customer including a $250,000 limit for cash if the brokerage firm fails. All three firms also carry excess-SIPC coverage from private insurers.

Can I do fractional shares at Vanguard?

No, Vanguard does not support fractional share trading on individual stocks or ETFs; you can only own fractional shares of Vanguard mutual funds via automatic reinvestment. Fidelity offers full fractional share support on stocks and ETFs starting at $1. Schwab offers fractional shares on S&P 500 stocks only.

Is Charles Schwab the same as TD Ameritrade now?

Yes, Charles Schwab completed the acquisition of TD Ameritrade in 2020 and the client account migration to the Schwab platform was completed in 2023. TD Ameritrade branded accounts, thinkorswim, and Ameritrade IRAs all now sit under Charles Schwab. thinkorswim is preserved as a Schwab advanced trading platform.

Which brokerage has the lowest total cost for a $100,000 buy-and-hold portfolio?

At $100,000 in a buy-and-hold Total US Market portfolio, all three brokerages are effectively free at the commission line and the difference is at the expense ratio. Fidelity ZERO (0.00 percent) is technically cheapest, Vanguard VTI (0.03 percent) is close behind, Schwab SCHB (0.03 percent) is equivalent to Vanguard. Over 30 years the ZERO advantage is roughly $2,700 on a $100,000 base.

Should I roll over my old 401(k) to Fidelity, Schwab, or Vanguard?

Roll over to whichever brokerage your current employer 401(k) is at, unless the fund lineup there is materially worse; consolidating simplifies management. If no employer preference exists, Fidelity for the fractional share and cash sweep advantages, Vanguard for pure index fund exposure. The rollover itself is free and non-taxable when done as a direct rollover.

Do these brokerages charge for check writing or debit cards?

Fidelity, Schwab, and Vanguard all offer free check writing on their standard brokerage accounts. Fidelity Cash Management Account and Schwab High Yield Investor Checking both offer debit cards with ATM fee rebates worldwide. Vanguard offers debit access on its VanguardAdvantage account. Schwab has the strongest banking integration.

Which brokerage has the best mobile app?

Fidelity and Schwab both have well-rated mobile apps with full trading, deposit, and account management. Vanguard's app has historically lagged and is a common critique. If mobile-first management is important, Fidelity or Schwab is the safer pick.

Do I need a brokerage account to buy an ETF like VOO?

Yes, you need a brokerage account with any of Fidelity, Schwab, Vanguard, or another SIPC-member brokerage to buy the Vanguard S&P 500 ETF (VOO) or any other ETF. VOO trades on the New York Stock Exchange and requires a brokerage account to place the trade.

Are Fidelity, Schwab, and Vanguard safe from failure?

All three are well-capitalised regulated broker-dealers under FINRA oversight and SIPC coverage. Fidelity is privately held; Schwab is NYSE-listed; Vanguard is client-owned. All three publish audited financial statements. The SEC and FINRA supervise operations. In practical terms, all three are among the safest brokerages available to US retail investors.

Which brokerage is best for a Roth IRA in 2026?

Fidelity is the most popular Roth IRA custodian in the US and the fractional share plus zero expense ratio ZERO funds make it particularly efficient for small monthly contributions. Vanguard is the philosophical choice for buy-and-hold index investing. Schwab is a strong third with integrated banking.

How do I earn cashback via ShopBack while I invest?

Cashback on ShopBack applies to eligible US retailers and does not overlap with brokerage account funding or investment activity. Activate ShopBack via the Chrome or Safari extension when you shop on supported retailers and treat the brokerage separately as a long-term compounding tool.
