M1 Finance Review 2026: Pies, Fees, and Is It Worth It?
M1 Finance sits in an unusual spot: it’s not quite a robo-advisor and not quite a traditional brokerage. It lets you build a custom portfolio of stocks and ETFs, then automates the buying and rebalancing the way a robo-advisor would. This M1 Finance review covers how the “Pies” system actually works, the fee structure that changed this year, and whether the hybrid model is right for you.
Short version: M1 is excellent for hands-on investors who want a specific allocation managed automatically, but the 2026 fee change means small accounts now pay a monthly fee they didn’t before. Here’s the detail.

What Is M1 Finance?
M1 Finance is a brokerage that blends self-directed investing with automation. You build a “Pie” — a visual portfolio where each slice is a stock or ETF with a target percentage — and M1 automatically directs new deposits to keep your allocation on target. You get the control of picking your own holdings with the convenience of automatic rebalancing. It’s a different philosophy from a pure robo-advisor like Betterment, which picks the portfolio for you.
Key Features
The Pie system
Pies are M1’s signature feature. You set target percentages — say 60% VTI, 30% VXUS, 10% BND — and every time you add money, M1 buys to move you toward those targets. You can build your own Pie from scratch or start from one of M1’s pre-built “Expert Pies.” For investors who know the allocation they want, it’s the cleanest way to maintain it automatically.
Fractional shares
M1 supports fractional shares on thousands of stocks and ETFs, so every dollar gets invested rather than sitting as cash waiting for a whole share. That matters most for smaller accounts and higher-priced stocks.
Automatic rebalancing
As you contribute, M1 rebalances by directing new money to underweight slices. It doesn’t sell to rebalance by default (which helps avoid taxable events), making it tax-aware in a way that suits long-term buy-and-hold investors.
M1 Borrow
Once your account crosses a balance threshold, M1 Borrow lets you take a low-rate margin loan against your portfolio. It’s a useful flexibility feature, though margin always carries risk and isn’t something beginners should reach for.
How M1’s Pies actually work
The Pie is the whole reason M1 exists, and it is the thing most reviews describe without explaining. It is worth understanding properly before you decide whether this platform suits you, because it changes what you can and cannot do with your money.
A Pie is a target allocation, not a purchase. You build a circle made of slices, and each slice is a holding — an individual stock, an ETF, or another Pie — with a percentage weight you choose. The percentages must total 100%. From then on, every dollar you deposit is split across those slices according to those weights, automatically, without you placing a single trade.
That inversion is the point. At a conventional broker you decide what to buy each time money arrives. At M1 you decide the shape of the portfolio once, and deposits maintain that shape on their own.
Slices, and why fractional shares matter here
Because slices are percentages rather than share counts, M1 has to buy fractions of shares to hit your weights. A $100 deposit into a Pie holding a $600 share simply buys a sixth of one. Without fractional support the whole model would collapse into rounding errors, which is why fractional shares are foundational to M1 rather than a bonus feature.
Nested Pies
A slice can itself be a Pie. That lets you build something like a 60% “Core Index” Pie, a 30% “Dividend” Pie and a 10% “Speculative” Pie, each with its own internal holdings, and adjust one without disturbing the others. It is the closest thing in consumer investing to running your own fund-of-funds, and it is genuinely useful for anyone who thinks about a portfolio in buckets.
How rebalancing really behaves
M1 rebalances with new money first. When you deposit, it directs the cash toward whichever slices are furthest below their target weight, nudging the portfolio back into shape without selling anything. That is the quietly valuable part: in a taxable account, buying your way back to balance avoids realizing gains, where a conventional rebalance sells winners and creates a tax bill.
You can also trigger a full rebalance manually, which does sell overweight positions and can have tax consequences. It is a button you press deliberately, not something M1 does to you.
The trade-off nobody puts in the headline
M1 is not a trading platform, and Pies are why. Orders execute in a daily trade window rather than the moment you press the button, so you do not control your execution price. For an investor contributing monthly and holding for years, that is irrelevant. If you want to buy a specific stock at a specific price this afternoon, M1 is structurally the wrong tool — not a worse version of a broker, but a different kind of product.
M1 Finance Pricing and Fees (2026)
This is the part that changed. M1 discontinued its old “M1 Plus” membership and moved to a single structure with a monthly platform fee for smaller accounts.
| Item | Cost |
|---|---|
| Platform fee (under $10k assets) | $3/month |
| Platform fee ($10k+ or active personal loan) | $0 (waived) |
| Trading commissions | $0 |
| Brokerage minimum | $100 |
| Retirement account minimum | $500 |
| Outgoing account transfer | $100 |
The headline: M1 no longer charges management fees or trading commissions, but the new $3/month platform fee applies until you reach $10,000 in total M1 assets. On a small starter account that fee is a meaningful percentage drag — $36/year on a $1,000 balance is 3.6%. Watch also for an inactivity fee on tiny dormant accounts and the $100 outgoing transfer fee if you ever leave.

What M1 actually costs, verified at source
Read from M1’s own platform fee disclosure and pricing pages on 24 September 2026:
| Item | Cost |
|---|---|
| Platform fee | $3 a month, unless waived — see below |
| IRA fee (IRA-only clients) | $3 a month, same waiver |
| Maximum platform cost | $3 a month total, however many accounts you hold — the two fees are never charged together |
| Commissions / management fees | $0 on self-directed investing |
| M1 Margin Loans | 5.90%, and require at least $2,000 invested per account |
| High-Yield Cash Account | $100 minimum initial deposit |
The waiver is the number that decides whether M1 is cheap or expensive for you. The $3 disappears if either of these is true:
- Your aggregate M1 balance reaches $10,000 for at least one day during your 30-day billing cycle, or
- you have an active M1 Personal Loan.
Note how forgiving that first condition is: it is one day in the cycle, not an average and not a daily minimum. Above roughly $10,000 invested, M1 is effectively free.
Below that line the maths turns against it, and this is the part worth stating bluntly. $36 a year on a $2,000 balance is 1.8% annually — more than most robo-advisors charge and many times the expense ratio of a plain index fund. On $1,000 it is 3.6%. A flat fee is regressive by design: the smaller your balance, the larger the bite. If you are starting with a few hundred dollars and building slowly, a broker with no platform fee will cost you less until you cross $10,000.
Who Should Use M1 Finance?
DIY investors who want automation. If you know the allocation you want and want it maintained automatically without picking a pre-set robo portfolio, M1 is the best tool for that specific job.
Investors with $10k+ to invest. At that level the platform fee is waived and M1’s value proposition is strongest — control plus automation at no ongoing cost.
Who should look elsewhere: If you’re just starting with a small balance, that $3/month fee is a real drag — a zero-fee option may suit you better.

Our Verdict
If you want control over your holdings and plan to fund the account past $10k, M1’s combination of automation and flexibility is genuinely hard to match. If you’re starting small or want tax-loss harvesting, a traditional robo-advisor or a zero-fee brokerage is the better first move. Either way, read our guide on how to invest in index funds before you build your first Pie.
