Choosing a brokerage account is one of the most consequential decisions you'll make as an investor — and one you'll rarely need to revisit if you make the right choice upfront. The good news: the major brokerages have converged on $0 commissions and $0 minimums, so the differences that matter most are more subtle: fund selection, expense ratios, tools, customer service, and whether the platform's incentives align with your long-term goals.
This guide breaks down every major option so you can pick the right home for your investments.
The Big Picture: What Changed in Brokerage Competition
The brokerage industry went through a seismic shift in October 2019 when Charles Schwab eliminated trading commissions, triggering a domino effect where Fidelity, TD Ameritrade, E*TRADE, and every other major brokerage immediately followed.
Today, the commission wars are over — everyone charges $0. Competition has shifted to fund expense ratios, account features, and the quality of the investing experience. This is largely great for individual investors, though it's worth understanding how brokerages now make money (primarily through interest on cash balances, premium services, and in some cases payment for order flow).

Fidelity: Best Overall Brokerage for 2026
Fidelity is the top recommendation for the majority of investors — beginners, intermediate, and experienced alike.
What makes Fidelity exceptional:
ZERO expense ratio funds. Fidelity offers four index funds with 0.00% expense ratios — the lowest possible cost:
- FZROX — Fidelity ZERO Total Market Index Fund (covers ~2,700 US stocks)
- FZILX — Fidelity ZERO International Index Fund (covers developed and emerging international markets)
- FZIPX — Fidelity ZERO Extended Market Index Fund (mid/small caps)
- FNILX — Fidelity ZERO Large Cap Index Fund (S&P 500 equivalent)
The catch: ZERO funds are proprietary to Fidelity. If you transfer your account to another brokerage, these funds must be sold and repurchased, potentially triggering a taxable event in a non-retirement account. For Roth IRA investors (where no taxes apply on sales), this is a non-issue.
No account minimums. Open a Roth IRA, Traditional IRA, or taxable brokerage with $1.
Fractional shares on ETFs and stocks. You can buy $50 of VTI, $30 of BND, and $20 of VXUS regardless of share prices.
Excellent customer service. Fidelity's phone support and online chat are consistently rated among the best in the industry. When you're learning and something confusing happens, this matters enormously.
Research and education tools. Fidelity's Learning Center is genuinely excellent — free courses on investing basics, retirement planning, and portfolio construction.
No payment for order flow on equities. Fidelity routes orders to seek best execution rather than selling order flow to market makers, which can mean slightly better prices on trades.
Best for: Beginners, cost-conscious investors, Roth IRA holders, anyone who wants maximum simplicity at minimum cost.
Weakness: ZERO funds are not portable; the trading interface can feel overwhelming for total beginners.
Charles Schwab: Best Runner-Up
Schwab and Fidelity are extremely similar, and choosing between them often comes down to personal preference. Here's where Schwab differentiates:
Key Schwab funds:
- SWTSX — Schwab Total Stock Market Index Fund (0.03%)
- SCHB — Schwab US Broad Market ETF (0.03%)
- SWISX — Schwab International Index Fund (0.06%)
- SCHF — Schwab International Equity ETF (0.06%)
- SWAGX — Schwab US Aggregate Bond Index Fund (0.04%)
Schwab's advantages over Fidelity:
- Banking integration: Schwab's checking account has no foreign transaction fees, unlimited ATM fee reimbursements worldwide, and no monthly fees. If you travel internationally or want a one-stop financial institution, Schwab wins.
- Schwab Intelligent Portfolios: Free automated investing with $5,000 minimum — no advisory fee. (Note: the free version requires a cash allocation of 6–10%, which some critics argue is a hidden cost. Schwab Intelligent Portfolios Premium costs $30/month for unlimited financial planning advice.)
- thinkorswim platform: Schwab acquired TD Ameritrade and kept thinkorswim, its industry-leading trading platform — irrelevant for index fund investors but excellent for options traders.
Best for: Investors who want banking + brokerage combined, frequent international travelers, traders who want advanced tools alongside their long-term portfolio.
Weakness: Fund expense ratios slightly higher than Fidelity's ZERO funds (0.03% vs 0.00% — negligible in dollar terms).
Vanguard: Best for Fund Selection and Investor-Ownership Structure
Vanguard invented the index fund and pioneered low-cost investing. It has a unique ownership structure: the funds own the company, which means Vanguard has no external shareholders demanding profits. Every cost reduction goes to fund investors.
Key Vanguard funds:
- VTI — Vanguard Total Stock Market ETF (0.03%, 3,600+ US stocks)
- VXUS — Vanguard Total International Stock ETF (0.07%, 8,000+ international stocks)
- BND — Vanguard Total Bond Market ETF (0.03%)
- VTSAX — Vanguard Total Stock Market Index Admiral Shares (0.04%, $3,000 minimum)
- VTIAX — Vanguard Total International Stock Index Admiral Shares (0.11%, $3,000 minimum)
- VT — Vanguard Total World Stock ETF (0.07%, holds entire global market in one fund)
Vanguard's advantages:
- Most trusted brand in index fund investing
- VTI, VXUS, and BND are available at every brokerage — no portability issues
- Strong track record and longest history of low-cost investing
- Target-date funds are industry standard: Vanguard Target Retirement 2055 (VFFVX) at 0.08% is a complete portfolio in one fund
Vanguard's weaknesses:
- Mobile app and website are noticeably behind Fidelity and Schwab in design and usability
- Admiral Shares mutual funds require $3,000 minimums — ETFs have no minimum but require whole-share purchases at some brokerages
- Customer service is slower and less accessible than Fidelity
- No ZERO-fee funds (Fidelity's ZERO funds are slightly cheaper than Vanguard's equivalent ETFs)
Best for: Investors who prioritize fund quality and institutional trust over UX polish; investors who hold Vanguard ETFs across multiple brokerages.
M1 Finance: Best for Automated Portfolio Investing
M1 takes a fundamentally different approach: you build a portfolio "pie" with target percentages for each holding, and M1 automatically purchases fractional shares to maintain your allocation when you add money. It's a free automated investing platform.
Key features:
- Automatic portfolio rebalancing — deposits are automatically directed to underweight holdings
- Fractional shares of any ETF or stock
- M1 Plus ($3/month): Adds an afternoon trading window, 1% cash back credit card, and 1.5% APY on M1 checking
- $100 minimum for taxable accounts, $500 for IRAs
Best for: Set-it-and-forget-it investors who want automation without paying a robo-advisor fee; investors who want to hold a specific three-fund or other portfolio allocation automatically maintained.
Weakness: No proprietary low-cost funds; less educational content than Fidelity; $100 minimum excludes those starting with less.
Robinhood: Best App Design, Worst Long-Term Incentives
Robinhood deserves credit for bringing $0 commissions to the mainstream and designing a genuinely excellent mobile app. But its business model creates conflicts with long-term investors.
What Robinhood does well:
- Cleanest, most intuitive mobile interface in the industry
- Instant account opening (minutes, not days)
- $0 minimums, fractional shares, $0 commissions
- SIPC-insured up to $500,000 against broker failure
- Robinhood Gold ($5/month): 4.9% APY on uninvested cash, access to Level III options data
What Robinhood does poorly:
- Payment for order flow: Robinhood's main revenue source is selling customer order flow to market makers. This may result in slightly worse execution prices — not illegal, but not in your best interest.
- Gamified interface: The platform uses design psychology (notifications, streak features, prominent "popular stocks" lists) to encourage frequent trading, which hurts long-term returns for most investors.
- Limited research tools: Compared to Fidelity or Schwab, research capabilities are thin.
- No proprietary low-cost index funds: You can buy Vanguard or iShares ETFs, but there's no ZERO-fee equivalent.
- Customer service issues: Robinhood's support has historically been slower and less accessible than the big three.
Best for: Investors with strong discipline to ignore the gamification and use it exclusively for boring index fund investing; those who need the absolute simplest interface to get started.
Webull: Best for Active Traders, Not for Beginners
Webull offers $0 commissions, advanced charting, extended hours trading, and a strong platform for technical analysis. For long-term index fund investors, there's nothing here that Fidelity doesn't do better.
Best for: Active traders who want advanced tools without paying TD Ameritrade-era commissions.
Betterment: Best Robo-Advisor for Hands-Off Investors
Betterment is not a traditional brokerage — it's a robo-advisor. You answer questions about your goals, timeline, and risk tolerance, and Betterment builds and manages a globally diversified ETF portfolio automatically.
Costs:
- Betterment Digital: 0.25% annual advisory fee on all assets
- Betterment Premium: 0.40%/year with $100,000 minimum — includes unlimited financial advisor calls
On $10,000: The 0.25% annual fee is $25/year. That's reasonable for completely hands-off management. On $100,000: The 0.25% fee is $250/year. At this level, it's worth considering whether you'd prefer to manage a three-fund portfolio yourself at Fidelity for near-zero cost.
Betterment uses a portfolio of low-cost iShares and Vanguard ETFs with expense ratios around 0.07–0.15%, plus the advisory fee on top.
Best for: Investors who genuinely want no involvement in investment decisions and are willing to pay 0.25%/year for fully automated management.
Tax-Advantaged Accounts: Where to Open What
The account type matters as much as the brokerage. Here's what to prioritize:
Roth IRA (first priority for most millennials): Contribute after-tax dollars, all future growth is tax-free. 2026 contribution limit: $7,000/year ($8,000 if 50+). Income limits apply: phases out at $150,000–$165,000 (single) and $236,000–$246,000 (married filing jointly). Open at Fidelity for FZROX access.
401(k) with employer match (match first, always): Contribute at least enough to capture your full employer match before opening an IRA. Free money is always the first priority.
401(k) beyond the match: If your 401(k) has good low-cost funds, max it after funding your Roth IRA. If your 401(k) has only expensive funds, prioritize the Roth IRA first.
HSA (Health Savings Account, if eligible): Triple tax advantage — deductible contributions, tax-free growth, tax-free withdrawals for medical expenses. Often called the "secret IRA" — invest the balance in index funds and use it as a retirement vehicle if you can pay medical expenses out of pocket today.
Taxable brokerage (after tax-advantaged accounts are maxed): No tax advantages, but no contribution limits or withdrawal restrictions. Fidelity and Schwab are both excellent choices.
How to Transfer a Brokerage Account
If you already have an account somewhere and want to move it:
- Open a new account at your target brokerage (Fidelity, Schwab, or Vanguard)
- Initiate an ACAT transfer (Automated Customer Account Transfer) from the new brokerage — you do this at the receiving brokerage, not the sending one
- The transfer is free at most brokerages and typically takes 3–7 business days
- Most investments transfer in-kind (you keep your shares), though some proprietary funds (like Fidelity's ZERO funds) may need to be sold first
Important: Selling investments to transfer triggers taxable events in non-retirement accounts. In retirement accounts (Roth IRA, Traditional IRA), transfers are tax-free.
Our Picks by Investor Type
Total beginner, first account: Fidelity (Roth IRA, buy FZROX + FZILX)
Beginner who wants automation: M1 Finance (set up a three-fund pie, automate deposits)
Wants banking and investing combined: Charles Schwab
Already experienced, prioritizes fund quality: Vanguard (hold VTI/VXUS/BND)
Completely hands-off, willing to pay advisory fee: Betterment
Active trader alongside long-term portfolio: Charles Schwab (thinkorswim for trading, SWTSX for long-term)
The Bottom Line
For the vast majority of millennial investors building long-term wealth through index fund investing, Fidelity is the clear winner in 2026. The combination of zero-fee funds, zero minimums, fractional shares, excellent customer service, and strong educational resources is unmatched.
If you're already at Schwab or Vanguard, there's no compelling reason to move — both are excellent and the fund cost differences are measured in fractions of a percent. Where you invest matters far less than how you invest: consistently, in diversified low-cost index funds, across your full working life.
Choose a brokerage, open a Roth IRA, pick a total market index fund, set up automatic investing, and stop worrying about the rest.

Frequently Asked Questions
Which brokerage is best for beginners?
Fidelity wins for most beginners: $0 commissions, no account minimums, fractional shares, excellent research tools, and ZERO expense ratio index funds (FZROX, FZILX). Charles Schwab is a close second with similar features. Both have excellent customer service, which matters when you're learning.
Is Robinhood safe?
Robinhood is SIPC-insured and regulated, so your investments are protected up to $500,000 against broker failure. However, Robinhood's interface is designed to encourage frequent trading (which hurts returns) and their revenue model depends on payment for order flow, which may result in slightly worse trade execution. Better options exist for long-term investors.
