If you’ve been shopping around for a brokerage and landed on M1 Finance or Fidelity, you’re in good company — and in a genuinely tough spot. Both platforms are excellent. But they serve different investors in meaningfully different ways. We spent time analyzing fee structures, investment options, automation features, and usability to give you a clear answer.
The Core Difference in One Sentence
M1 Finance is built for hands-off, automated portfolio investors. Fidelity is built for everyone — from active traders to retirees to beginners who want human support.
M1 Finance: Automation-First Investing
M1 Finance pioneered the “pie” investing model. You build a pie of ETFs, stocks, or funds, set target allocations, and M1 automatically rebalances as you deposit. There are no trading commissions and no management fees on the basic account. The interface is clean and minimal — intentionally so.
- Minimum to invest: $100 ($500 for retirement accounts)
- Fractional shares: Yes, on all securities
- Automated rebalancing: Continuous, built-in
- M1 Plus (premium): $3/month, unlocks afternoon trading windows, 1% cash back card
- Research tools: Minimal — this is a “set and forget” platform
In our research, M1 Finance shines brightest for investors who have a plan and want execution on autopilot. It’s not built for stock screeners, technical analysis, or active trading.

Fidelity: The Full-Service Powerhouse
Fidelity has been around since 1946 and manages over $12 trillion in assets. Its brokerage platform is one of the most capable on the market — zero-commission trades, industry-leading research, access to bonds and international markets, and a suite of index funds with zero expense ratios.
- Minimum to invest: $0
- Fractional shares: Yes (called “Fidelity Stocks by the Slice”)
- Research tools: Excellent — Morningstar, Reuters, equity reports
- Index funds: Fidelity ZERO funds with 0% expense ratio
- Human advisors: Available at no extra cost for basic guidance
Fidelity also supports IRAs, 401(k)s, HSAs, 529 plans, and custodial accounts — making it a true one-stop shop. If you ever want to graduate to more complex strategies, you won’t outgrow it.

Which One Should You Choose?
Choose M1 Finance if: You have a clear investment strategy (like a three-fund portfolio), want automation, and don’t plan to trade actively. It’s especially good for FIRE-oriented investors who want to “set and forget.”
Choose Fidelity if: You’re a beginner who wants guidance, you want access to Fidelity’s zero-ER index funds, you trade individual stocks or ETFs, or you want all your financial accounts under one roof.
One more thing we noticed: Fidelity allows you to hold cash in a money market fund earning competitive yields, while M1’s cash management features (without M1 Plus) are more limited. If you keep a significant cash buffer, that matters.
Can You Use Both?
Yes — and many investors do. A common approach is using Fidelity for your core taxable account and IRA (especially for Fidelity ZERO funds), while running M1 Finance as a satellite portfolio for a more concentrated strategy. There’s no rule against diversifying across brokerages.
Frequently Asked Questions
Does M1 Finance have hidden fees?
M1 Finance doesn’t charge management fees or trading commissions on the standard plan. However, M1 Plus is $3/month, and there’s a $100 inactivity fee if your account has less than $20 and you haven’t logged in for 90 days.
Is Fidelity good for beginners?
Fidelity is one of our top picks for beginners, largely because of its zero-minimum accounts, zero-expense-ratio index funds, and access to free financial guidance. The interface can feel overwhelming at first, but the core investing flow is simple.
Does M1 Finance offer tax-loss harvesting?
No — M1 Finance does not offer automatic tax-loss harvesting on standard accounts. This is one area where dedicated robo-advisors like Betterment or Wealthfront have an edge.
Is my money SIPC-insured with M1 Finance?
Yes. M1 Finance uses Apex Clearing as its custodian, and accounts are covered by SIPC up to $500,000 (including $250,000 for cash).
