If you're building wealth for the next decade or beyond, your brokerage choice matters more than most people realize.

Both platforms are solid — but they're designed for different kinds of investors. M1 Finance is a hybrid robo-advisor and self-directed brokerage built around automated, portfolio-based investing. Fidelity is a full-service financial institution with decades of track record, offering everything from index funds to estate planning. Which one fits you better depends on what kind of long-term investor you are.

This comparison is for you if you're:

• A buy-and-hold investor looking to automate contributions
• Someone choosing your first (or next) brokerage for retirement accounts
• A DIY investor who wants low costs and solid tools
• Trying to decide between a streamlined fintech platform and an established financial giant

Let's dig into what each one offers.

M1 Finance Overview

Try M1 Finance

M1 Finance launched in 2015 with a pitch that felt genuinely different: combine the automation of a robo-advisor with the control of a self-directed brokerage. The result is a platform built around "Pies" — visual portfolio templates that let you set target allocations and then automate everything from there.

Here's the core idea: you create a Pie (or pick from dozens of pre-built ones), set your target allocations, and deposit money. M1 automatically buys fractional shares to keep your portfolio balanced. When you add new cash, it gets directed toward the underweight positions. It's clean, hands-off, and honestly perfect for long-term investors who don't want to worry about individual trades.

Key Features

• Pie-based portfolios with automatic rebalancing
• Dynamic rebalancing — new deposits go to underweight holdings rather than forcing you to sell and rebalance (more tax-efficient)
• Fractional shares down to 1/100,000th of a share
• M1 Borrow — margin lending at competitive rates (currently around 6.25%–7.25% depending on M1 Plus status)
• M1 Spend — integrated checking account with debit card
• M1 Plus ($36/year) — extra trading window, lower borrow rates, cashback on M1 Spend, and other perks

Pricing

M1 Finance's core account is free — no commissions, no management fees. M1 Plus runs $36/year and unlocks an afternoon trading window, lower margin rates, and enhanced cash management features. Here's what stands out: there are no percentage-based advisory fees on the standard platform. For long-term investors watching their portfolio grow, that's a major advantage.

Limitations

• Only one trading window per day (9:30 AM ET) on the free plan; two with M1 Plus
• No options trading
• No mutual fund access
• Limited research and charting tools
• No automated tax-loss harvesting (you'd handle it manually)

Fidelity Overview

Fidelity

Fidelity is one of the world's largest and most respected brokerage firms, managing over $12 trillion in assets as of early 2026. It's a full-service operation handling everything from basic stock trades to complex estate planning, 529 college savings plans, and employer-sponsored 401(k)s.

What makes Fidelity stand out for long-term investors is its collection of zero-expense-ratio index funds (Fidelity ZERO), its massive mutual fund selection, and robust retirement planning tools. It's honestly a platform you could use for your entire financial life and never feel like you've outgrown it.

Key Features

• Fidelity ZERO index funds — 0.00% expense ratio on four index funds
• Thousands of mutual funds including no-transaction-fee options
• Active Trader Pro — advanced desktop trading platform
• Fidelity Go — robo-advisor option (free under $25K; 0.35%/yr above $25K)
• Full retirement suite — Traditional, Roth, SEP, SIMPLE IRAs, solo 401(k), HSA, 529 plans
• Fidelity Cash Management — checking account with ATM fee reimbursement worldwide
• Extensive research from 20+ independent providers
• 200+ investor centers for face-to-face support

Pricing

Fidelity charges $0 commissions on stocks, ETFs, and options (options contracts still carry a $0.65 fee each). There's no account minimum for brokerage or retirement accounts. Fidelity Go, its robo-advisor, is free for balances under $25,000 and charges 0.35% annually above that. And those Fidelity ZERO funds? Literally no expense ratio — a rare find in the industry.

Limitations

• The platform can feel overwhelming for beginners because it tries to serve everyone — day traders, retirees, long-term investors
• Fidelity Go's automation is separate from your main brokerage and less customizable than M1's Pies
• Self-directed accounts don't have built-in portfolio automation (you manage rebalancing yourself)
• Cryptocurrency investing is pretty limited compared to newer platforms

Feature-by-Feature Comparison: M1 Finance vs Fidelity for Long-Term Investing 2026

User Interface & Ease of Use

M1 Finance wins on pure simplicity. The Pie interface is intuitive — you see your portfolio as a visual circle chart, drag to adjust allocations, and let the system handle the rest. There's almost no clutter because M1 intentionally limits what you can do (no day trading, no options, no mutual funds). For someone who wants to set up their portfolio and move on, that's actually a strength.

Fidelity's interface has gotten much better, and the 2025–2026 redesign cleaned things up nicely. But it's still a comprehensive platform trying to serve day traders, retirees, and everyone in between. When you're new to the platform, navigating between the brokerage dashboard, NetBenefits (for workplace accounts), and Fidelity Go can feel scattered. Once you learn the layout, though, the depth is genuinely impressive.

Winner: M1 Finance for pure simplicity; Fidelity if you want comprehensive features.

Core Features for Long-Term Investing

Here's where things get interesting. Both platforms offer commission-free stock and ETF trading with fractional shares. But the philosophy behind them is completely different.

M1 Finance is all about portfolio-based investing. You define your target allocation once, and the platform maintains it automatically with every deposit. Dynamic rebalancing means you're rarely selling to rebalance — new money just flows into underweighted positions. For a long-term, buy-and-hold strategy, this is incredibly powerful and tax-efficient.

Fidelity gives you access to a much wider investment universe: thousands of mutual funds (including ZERO funds), bonds, CDs, international markets, and more. But if you want automated portfolio management in a self-directed account, you'll need to rebalance manually or use Fidelity Go (which is a separate product and less flexible).

M1 Finance has the better core workflow for pure long-term buy-and-hold investing with automation. Fidelity wins on investment breadth.

Winner: Tie — it depends on whether automation or investment variety matters more to you.

Investment Selection

This one's pretty clear-cut. Fidelity offers a dramatically wider selection of investments. Need to own individual bonds? Want to invest in Fidelity's ZERO mutual funds? Trading covered calls? Buying CDs? Fidelity handles all of it. M1 Finance keeps things focused on stocks and ETFs.

For plenty of long-term investors, stocks and ETFs are honestly all they need. But the flexibility gap is definitely there.

Winner: Fidelity — significantly.

Pricing & Value

Both platforms charge $0 commissions on stocks and ETFs, so the baseline cost is the same for most long-term investors. Where they differ:

• M1 Finance charges no advisory fee for its core automated investing. M1 Plus at $36/year is totally optional.
• Fidelity Go charges 0.35%/year for portfolios over $25,000. On a $100,000 portfolio, that's $350 annually. On $500,000, it's $1,750.
• Fidelity ZERO funds have zero expense ratio — literally can't beat that.
• M1 Borrow offers competitive margin rates; Fidelity's margin rates are typically higher for smaller accounts.

If you're comparing M1's free automated investing to Fidelity Go's fee-based robo-advisor, M1 wins on cost. But if you're comparing a self-directed Fidelity account using ZERO funds (no advisory fee, no expense ratio) to M1, Fidelity actually comes out cheaper — you just lose the automation.

Winner: M1 Finance for automated investing; Fidelity for self-directed, ultra-low-cost investing.

Customer Support

Fidelity offers phone support, live chat, and over 200 investor centers across the country. Want to sit down with a real person to discuss estate planning, beneficiaries, or a major rollover? You can do that. For complex financial situations, having access to a human at a physical branch is genuinely valuable.

M1 Finance offers email and in-app chat. Support has improved, but there's no phone option for standard accounts and no physical locations. For a platform designed to be hands-off, this usually works fine — but when something goes wrong with a transfer or account issue, the lack of phone support can be frustrating.

Winner: Fidelity — clearly.

Mobile App

Both apps are well-designed and intuitive. M1 Finance's mirrors its web experience beautifully — clean, visual, and centered on your Pies. Depositing money, checking your portfolio, and tweaking allocations are all straightforward. It's rated 4.6 stars on iOS.

Fidelity's app (4.7 stars on iOS) has improved significantly and now offers a streamlined experience for casual investors while still providing access to advanced tools. The addition of goal-tracking features makes long-term planning easier.

Winner: Tie — both are excellent. M1 is simpler; Fidelity is more feature-rich.

Security & Compliance

Both are SIPC members with up to $500,000 in securities protection ($250,000 for cash). Both offer two-factor authentication and bank-level encryption.

But Fidelity adds a Customer Protection Guarantee that reimburses losses from unauthorized activity — something not all brokerages spell out explicitly. And because Fidelity does its own clearing rather than using a third party, it has tighter control over account security.

M1 Finance uses Apex Clearing for trade execution and custody, which is solid and widely used, but it adds another party to the security chain.

Winner: Fidelity — the self-clearing operation and explicit protection guarantee give it an edge.

Who Should Choose M1 Finance?

Try M1 Finance

M1 Finance is your better bet if you:

• Want true set-it-and-forget-it investing — You've picked your asset allocation (or you like one of M1's expert Pies) and want every dollar automatically invested according to that plan.
• Prefer a clean, distraction-free interface — No market alerts, no options chains tempting you, no features you'll never use cluttering the screen.
• Are building a long-term ETF or stock portfolio — If your strategy is "buy VTI, VXUS, and BND every paycheck and rebalance automatically," M1 was literally made for you.
• Don't want to pay advisory fees — M1's free automated investing beats Fidelity Go's 0.35% fee, especially as your portfolio grows larger.
• Want banking integrated with investing — M1 Spend gives you a solid checking account tied directly to your investment account.

M1 Finance is especially good for younger investors in their 20s–40s who have a clear investment plan and want maximum automation with minimum cost.

Who Should Choose Fidelity?

Fidelity

Fidelity makes more sense if you:

• Want all your investments in one place — Mutual funds, bonds, CDs, options, international markets — it's all there.
• Love the idea of ZERO funds — If your long-term strategy is built around low-cost index funds, Fidelity's 0.00% expense ratio funds are tough to beat.
• Need comprehensive retirement planning — HSAs, 529 plans, solo 401(k)s, estate planning — Fidelity covers needs that M1 simply doesn't.
• Value real human support — A phone call or a face-to-face meeting at a local branch matters to you. Fidelity's support infrastructure is way ahead.
• Have a complex financial picture — Multiple account types, beneficiary planning, trust accounts, workplace retirement plans — you want everything centralized.
• Want stability and longevity — Fidelity's been around since 1946. It's privately held, profitable, and doesn't depend on venture capital.

Fidelity is ideal for investors who want one financial home that can grow with them from their first Roth IRA all the way through retirement withdrawals.

Verdict: M1 Finance vs Fidelity for Long-Term Investing in 2026

Here's the reality: both are excellent platforms for long-term investing, and the right choice depends on what you prioritize most.

Go with M1 Finance if automation is your number one priority. No other brokerage matches M1's ability to automate a self-directed, portfolio-based strategy without advisory fees. If you know what you want to own and just want the platform to execute your plan every time you deposit, M1 Finance is unbeatable.

Go with Fidelity if you want the most versatile, feature-rich brokerage available. The combination of ZERO expense-ratio funds, a full range of account types, world-class research, and in-person support makes Fidelity the stronger all-around platform — even if you're doing more manual work to maintain your portfolio.

If I had to pick one for someone starting out and wanting simplicity? M1 Finance. If I had to pick one platform to manage my entire financial life for the next 30 years? Fidelity.

And here's a thought: many investors actually use both. M1 Finance for automated taxable investing and Fidelity for retirement accounts and mutual fund access. Nothing says you're limited to just one brokerage.

FAQ: M1 Finance vs Fidelity for Long-Term Investing 2026

Is M1 Finance safer than Fidelity?

Both are SIPC-insured up to $500,000. Fidelity is larger, more established, and does its own clearing, plus it has an explicit Customer Protection Guarantee. That said, M1 Finance (which uses Apex Clearing) is well-regulated and safe. Fidelity has a slight edge on perceived security, but both are solid.

Can I transfer my portfolio from M1 Finance to Fidelity (or vice versa)?

Yes. Both support ACATS transfers, which let you move your holdings without selling them. It typically takes 5–7 business days. One heads-up: M1 Finance charges $100 for outgoing transfers, while Fidelity doesn't charge for incoming transfers.

Does M1 Finance offer tax-loss harvesting?

Not automatically. M1 Finance doesn't have a built-in tax-loss harvesting feature like some robo-advisors (e.g., Wealthfront or Betterment). You can manually sell losing positions and reinvest, but it requires hands-on work. Fidelity also doesn't offer automatic tax-loss harvesting in standard brokerage accounts, though Fidelity Go includes it for managed accounts above $25,000.

Which is better for a Roth IRA in 2026?

Both are strong choices. M1 Finance works well if you want to build a custom ETF portfolio with automated contributions. Fidelity is better if you want access to ZERO index funds or prefer having all your accounts — Roth IRA, traditional IRA, HSA, 529 — together. For pure cost efficiency with zero management fees and zero fund expenses, Fidelity's self-directed Roth IRA using ZERO funds is hard to beat.

Does Fidelity have anything like M1 Finance's Pies?

Fidelity Go is the closest thing, but it's a separate product with less customization and a 0.35% annual fee for balances over $25,000. In Fidelity's standard brokerage account, there's nothing really equivalent to M1's Pie automation. Fidelity's Basket Trading feature (on Active Trader Pro) offers some portfolio-level tools, but it's not as intuitive or automated as M1.

Can I use M1 Finance and Fidelity together?

Absolutely, and plenty of investors do. A common setup is M1 Finance for a taxable brokerage account (using its automated investing) and Fidelity for retirement accounts (using ZERO funds and comprehensive account types). Having accounts at both platforms isn't a problem and can give you the best features from each.
