M1 Finance blends automation with hands-on control. Here's how it works, who it fits, and where it falls short.
Most robo-advisors take a simple approach: you answer a few questions, they pick a portfolio, and you never touch it again. M1 Finance goes in the opposite direction. It hands you the steering wheel and says, “Build whatever you want — we’ll just keep the car running.”
That’s either exactly what you’ve been looking for or exactly what you’ve been trying to avoid. This review will help you figure out which camp you’re in.

M1 calls itself a “finance super app,” but at its core it’s a brokerage with automation bolted on. You build something called a Pie — a visual breakdown of the stocks and ETFs you want to own, with each slice representing a target percentage of your portfolio.
Once your Pie is built, M1 handles the rest. When you deposit money, it automatically buys whatever’s underweight to keep you in balance. When you withdraw, it sells whatever’s overweight. You don’t place trades — you just fund the account and let the Pie do its job.
That’s the key mental shift. Traditional brokers make you pick individual buys and sells. Traditional robo-advisors pick everything for you. M1 lets you pick the recipe once, then automates the cooking.
Let’s say you want 40% in an S&P 500 index fund, 20% in a total bond ETF, 20% in a tech-heavy fund, and 20% split across five individual stocks. In M1, you’d build a Pie with those exact percentages.
Now you deposit $500. M1 looks at your current holdings, sees that your tech slice is underweight by the biggest percentage, and directs most of your $500 there. Next month, bonds might be the laggard. You don’t have to think about it.
You can also build Pies inside Pies. A “Core” Pie might hold your broad index funds, and a “Satellite” Pie might hold individual stock picks. You combine them into one master Pie with whatever weighting you want. It’s clean, visual, and frankly more intuitive than the menus most brokers use.
The headline is that M1 has no management fee on its basic tier. That’s unusual — Betterment charges 0.25%, Wealthfront charges 0.25%, and most human advisors charge 1% or more. M1 makes money through interest on uninvested cash, payment for order flow, and its paid tier, M1 Plus, which runs around $3 a month or $36 a year.
M1 Plus adds perks like a higher-yield cash account, lower margin rates on borrowing, and a second trading window each day. For most investors just building long-term wealth, the free tier is fine.
The account minimum is $100 for taxable accounts and $500 for retirement accounts. Once you’re in, there’s no minimum balance to maintain.
The Pie system rewards people who know what they want their portfolio to look like. If you’ve read a few John Bogle books and you’re dead set on a three-fund portfolio, M1 lets you build it once and automate it forever — for free. That’s genuinely hard to beat.
Fractional shares are another quiet superpower. You can own 0.03 shares of Amazon if you want. That means your Pie can stay perfectly balanced even if you’re only depositing $50 a month, because M1 can buy tiny slices of expensive stocks.
Borrowing is also integrated. If you have at least $2,000 in a taxable account, you can borrow against it at competitive rates through M1 Borrow. That’s useful for advanced users — and dangerous for everyone else. More on that in a second.
The biggest limitation is also the biggest selling point flipped around: M1 doesn’t give you advice. There’s no risk questionnaire, no auto-generated portfolio for beginners, no hand-holding. If you don’t know what you want to own, M1 isn’t going to tell you. It has pre-built “Expert Pies” you can start from, but even choosing one requires some baseline literacy.
Trading windows are another friction point. M1 executes trades in one daily window on the free tier (two on Plus). That’s intentional — it’s built for long-term investors, not active traders — but if you want to react to news in real time, you can’t.
Tax-loss harvesting, which Betterment and Wealthfront offer automatically, isn’t part of M1’s core offering in the way it is at those competitors. If that’s a big deal to you, factor it in.
And the margin borrowing product, while cheap, is genuinely risky. Borrowing against your portfolio to buy more stock is a fine way to amplify gains and an even better way to amplify losses. Most beginners should pretend that button doesn’t exist.
M1 is a great fit for the investor who’s done some reading, has a target allocation in mind, and wants to automate contributions without paying an advisory fee. If you’re nodding along to terms like “three-fund portfolio” or “sector tilt,” you’ll probably love it.
It’s a bad fit for the investor who wants to hand over the wheel entirely. If you’d rather answer five questions and never think about your portfolio again, Betterment or Wealthfront will serve you better. And if you want a human to call when markets get ugly, M1 isn’t that either.
M1 Finance is what you get when a brokerage and a robo-advisor have a baby: the automation of the latter with the control of the former, at a price point that’s hard to argue with. For DIY investors who want to stop manually placing trades without giving up control over what they own, it’s one of the best products on the market.
Just be honest with yourself about which kind of investor you are before you sign up.
If you’re ready to build your first Pie, you can open an M1 Finance account and start with as little as $100.
