What Is M1 Finance?
M1 Finance is an automated investing platform founded in 2015 by Brian Barnes. It occupies a unique middle ground in the investing app landscape: it gives you the control of a self-directed brokerage account combined with the automation of a robo-advisor — without charging the 0.25%+ annual management fee that most robo-advisors levy.
The platform is built around its signature "pie" concept: you visualize your portfolio as a pie, and each investment (stock or ETF) is a slice with a percentage weighting. Once you set your pie, M1 automatically allocates every new dollar you deposit according to those percentages, and dynamically rebalances over time. It's powerful, intuitive, and remarkably hands-off once it's set up.
As of 2026, M1 manages over $8 billion in assets and has earned a reputation as one of the best platforms for long-term, passive investors who want more customization than a traditional robo-advisor but less daily management than a full brokerage account.
How M1 Finance's Pie Investing Works
The "pie" is everything at M1. When you open an account, you build a portfolio by creating your pie — choosing from over 6,000 stocks and ETFs available on major U.S. exchanges — and assigning each a percentage weight. You can also choose from over 60 pre-built "Expert Pies" curated for different goals, including:
- General Investing — broad market diversification
- Retirement Date Funds — target-date style pies that shift conservative over time
- Responsible Investing (ESG) — socially and environmentally screened ETFs
- Income Earners — dividend-focused portfolios
- Hedge Fund Followers — mirrors top institutional holdings
- Sector Pies — technology, healthcare, real estate, and more
Once your pie is set, deposits are automatically invested proportionally. M1 also uses dynamic rebalancing: rather than selling assets (which could trigger taxes), it directs new money toward under-weight slices first, keeping your allocation on target without unnecessary tax events.
Fractional shares start at just $1, so even a $100 deposit can be spread across 10, 20, or more different securities.
M1 Finance Fees: What You'll Actually Pay
M1 used to market itself as completely free. In 2026, that's no longer fully accurate — but it's still one of the most affordable investing platforms available if you understand the fee structure.
| Fee Type | Amount | How to Avoid It |
|---|---|---|
| Trading Commissions | $0 | Always free |
| Monthly Platform Fee | $3/month | Keep ≥$10,000 in M1 assets OR have an active M1 Personal Loan |
| IRA Monthly Fee | $3/month | Waived if you already pay platform fee, have ≥$10K, or have active personal loan |
| Management Fee (AUM) | $0 | Always free — unlike Betterment (0.25%) or Wealthfront (0.25%) |
| Deposit / Withdrawal | $0 | Always free |
| Inactivity Fee | $20 | Accounts with under $50 balance + no activity for 90+ days |
Account Types Available
M1 Finance supports several account types, covering both taxable and tax-advantaged investing:

M1 Finance Features Deep Dive
🥧 The Pie System & Dynamic Rebalancing
M1's pie system is its biggest differentiator. You can build custom pies, use expert pies, or even nest pies within pies for complex strategies. The dynamic rebalancing approach — redirecting new cash to underweight slices rather than selling — is tax-efficient and means your portfolio stays on target without generating unnecessary capital gains taxes.
You can hold up to 100 securities in a single pie, and every investment can be a stock or ETF. Crypto was also added as an option for individual and joint accounts.
💰 M1 High-Yield Cash Account
M1 offers a high-yield cash account paying 3.10% APY with no minimum balance to earn the rate. The account operates through partner banks with FDIC pass-through insurance. This competes solidly with Marcus by Goldman Sachs and Ally Bank, especially since it's integrated directly into your investment account ecosystem.
🏦 M1 Borrow
Once you have at least $2,000 in your M1 brokerage account, you can borrow against your portfolio through M1 Borrow. The portfolio serves as collateral, which keeps interest rates significantly lower than credit cards or personal loans. You can borrow up to 35% of your portfolio value. There's no application process and no fixed repayment schedule.
Important: Borrowing against investments carries risk. If your portfolio value drops significantly, you may face a margin call requiring you to repay the loan or deposit more funds.
📋 M1 Personal Loans
M1 also offers unsecured personal loans (not backed by your portfolio) with:
- Loan amounts: $2,500 to $50,000
- Fixed APRs: 7.99% to 21.75%
- No origination fees or prepayment penalties
An active personal loan also waives your monthly platform fee — something worth considering if you planned to borrow anyway.
📱 Mobile App
M1's mobile app receives consistently high marks — typically 4.5+ stars on both the App Store and Google Play. It includes full pie-building and editing, portfolio performance tracking, deposit management, and access to M1 Borrow and the cash account. The interface is clean and not cluttered with noise that most active traders don't need.
M1 Finance vs. Competitors
| Platform | Min. to Start | Annual Fee | Rebalancing | Best For |
|---|---|---|---|---|
| M1 Finance | $100 | $0 AUM (+ $3/mo if under $10K) | Dynamic (cash-based) | DIY long-term investors |
| Betterment | $0 | 0.25% AUM | Automatic + tax-loss harvesting | True hands-off investing |
| Acorns | $0 | $3–$9/month flat | Automatic | Micro-investing beginners |
| Wealthfront | $500 | 0.25% AUM | Automatic + tax-loss harvesting | Hands-off with tax optimization |
| Fidelity | $0 | $0 | Manual | Full brokerage, active investors |
The bottom line on comparisons: If you want total automation with tax-loss harvesting and don't want to think about which stocks to pick, Betterment or Wealthfront are better. If you want to build your own portfolio and automate it — without paying an AUM fee — M1 is hard to beat.
Who Should Use M1 Finance?
✅ M1 Finance is a great fit if you:
- Have a buy-and-hold mindset and want to invest for 5+ years
- Want to pick your own stocks and ETFs but don't want to manually manage every deposit

- Want to trade throughout the day or use advanced order types
- Are just starting with under $500 (the $3/month fee is proportionally high)
- Need tax-loss harvesting (M1 doesn't offer it)
- Want human financial advisor access

⚖️ Our Verdict: M1 Finance Review 2026
M1 Finance is an excellent platform for experienced-enough investors who want their own curated portfolio on autopilot. The pie system is genuinely innovative, the fee structure is competitive (especially at $10K+), and the integration of investing, borrowing, and high-yield cash in one platform adds real value. The $3/month fee for smaller accounts is the main caveat — factor it in carefully if you're starting small. For long-term, buy-and-hold investors who've outgrown basic robo-advisors but don't want to manage everything manually, M1 Finance earns a strong recommendation.

Is M1 Finance safe?
Yes. M1 Finance is a registered broker-dealer and investment adviser regulated by the SEC and FINRA. Brokerage accounts are protected by SIPC up to $500,000 (including $250,000 for cash). Your investments are held at M1's custodian and are not at risk if M1 itself were to fail.
Does M1 Finance charge a fee?
M1 charges a $3/month platform fee for accounts with less than $10,000 in M1 assets and no active M1 Personal Loan. Accounts that meet either waiver condition pay no platform fee. There are no trading commissions or AUM-based annual fees regardless of account size.
What's the minimum investment for M1 Finance?
Individual, joint, and custodial brokerage accounts require a $100 minimum to open. Traditional, Roth, and SEP IRAs require $500. Trust accounts require $5,000. After the initial deposit, additional contributions can be smaller amounts.
Can I withdraw money from M1 Finance anytime?
Yes. You can request a withdrawal at any time with no withdrawal fee. Standard ACH transfers typically take 3–5 business days. Note that selling investments to fund a withdrawal may trigger capital gains taxes in taxable accounts.
How does M1 Finance compare to Betterment?
Betterment charges 0.25% of your assets annually and handles all investment decisions automatically, including tax-loss harvesting. M1 charges no AUM fee but requires you to build your own portfolio (or choose an expert pie). For a $50,000 portfolio, Betterment costs ~$125/year vs. $0 at M1 (if you're over the $10K waiver threshold). M1 wins on cost; Betterment wins on true hands-off automation.
Does M1 Finance offer tax-loss harvesting?
No. M1 Finance does not offer tax-loss harvesting. If this feature is important to you, consider Betterment or Wealthfront, both of which include it in their standard plans.
