M1 Finance Review (2026): Cost, Features, and Who It Suits
Last updated August 2026
Short answer
A pie-based investing platform where you choose the holdings and target weights and M1 automates the rebalancing. Between a robo-advisor and a brokerage. On cost, it is free tier plus a paid tier (verify current), and on the question that decides most of the day-to-day experience, whether it works with the brokerage account you already have, the answer is: No (holds your money at M1). It suits a self-directed investor with a clear allocation in mind who wants it maintained automatically rather than by hand. Where it falls short: Trading happens in scheduled windows rather than on demand, which suits long-term investing and frustrates anyone wanting control over execution. This review is published by Walnut, which competes with M1 Finance, and is written from public information rather than collected user ratings.
What M1 Finance is and how it works
You build a Pie of stocks and ETFs with target percentages, and every deposit is allocated to whatever is furthest below target, which rebalances the portfolio as you contribute rather than by selling. Trades execute in one or two daily windows rather than immediately, which is the design trade for the automation and the fractional-share support.
In category terms it is hands-off automated investing (robo-advisors), and the AI component specifically automates rebalancing toward weights you set. That phrase is worth reading literally: across this market, "AI" covers everything from a rebalancing rule to a conversational assistant, and the products are not interchangeable just because they share the label.
What M1 Finance does well
- You pick the holdings, which no conventional robo-advisor allows
- Contribution-based rebalancing avoids realising gains the way selling to rebalance does
- Fractional shares make precise target weights achievable on small amounts
These are real advantages, and if they describe what you want, M1 Finance is a reasonable choice regardless of what any competitor including us has to say about it.
Where M1 Finance falls short
Trading happens in scheduled windows rather than on demand, which suits long-term investing and frustrates anyone wanting control over execution.
- Scheduled trade windows mean you do not control execution timing
- It is a brokerage rather than an advice service, so nobody is telling you whether your Pie is sensible
What M1 Finance costs
Free tier plus a paid tier (verify current). Because it is not charged as a percentage of assets, the cost does not scale with your balance. That makes it proportionally cheaper as an account grows and relatively expensive on a small one, which is the opposite of how a robo-advisor fee behaves.
Fees change. The figure above is a guide rather than a quote, and the M1 Finance pricing breakdown goes into what else you pay on top. Confirm current pricing on M1 Finance's own site.
How M1 Finance compares with the alternatives
| Product | Cost | Connects your broker? | Best for |
|---|---|---|---|
| M1 Finance | Free tier plus a paid tier (verify current) | No (holds your money at M1) | People who want to choose the holdings but automate the maintenance |
| Betterment | ~0.25%/yr | No (holds your money) | Set-and-forget automated investing |
| Wealthfront | ~0.25%/yr | No (holds your money) | Hands-off investing with planning built in |
| SoFi | Free automated investing | No (holds your money) | Beginners in one money app |
| Schwab Intelligent Portfolios | No advisory fee; ETF expenses apply (verify current) | No (holds your money at Schwab) | Hands-off investing with no advisory fee, if you accept the cash allocation |
Within hands-off automated investing (robo-advisors), the products differ less on capability than the marketing suggests. Cost and whether your money has to move are the two variables that actually change your experience.
Where Walnut fits, and where it does not
To be upfront, since this is our site: the one factual difference worth knowing is that M1 Finance holds your money in its own account, while Walnut connects the brokerage you already have, read-only by default, and leaves your assets where they are. Walnut is free, with no paid plan and no fee on assets.
Where Walnut is the wrong choice: it will not manage money for you, it is not a registered investment adviser, it does no tax or estate planning, and it needs a brokerage account you already hold. If what you want is delegation rather than analysis, a robo-advisor or a human planner is the better answer and M1 Finance may well be it. The full self-assessment is on the Walnut review.
The bottom line on M1 Finance
M1 Finance: A pie-based investing platform where you choose the holdings and target weights and M1 automates the rebalancing. Between a robo-advisor and a brokerage, at free tier plus a paid tier (verify current). It fits a self-directed investor with a clear allocation in mind who wants it maintained automatically rather than by hand. The trade-off to accept: Trading happens in scheduled windows rather than on demand, which suits long-term investing and frustrates anyone wanting control over execution. If that trade-off is one you are happy with, it is a sound choice.
FAQ
What is M1 Finance?
A pie-based investing platform where you choose the holdings and target weights and M1 automates the rebalancing. Between a robo-advisor and a brokerage. It sits in the hands-off automated investing (robo-advisors) category, costs free tier plus a paid tier (verify current), and is best suited to people who want to choose the holdings but automate the maintenance.
How much does M1 Finance cost?
Free tier plus a paid tier (verify current). Because that is not a percentage of assets, the cost does not scale with your balance the way a robo-advisor fee does, which makes it cheaper proportionally as the account grows and more expensive on a small one. Verify current pricing on M1 Finance's own site.
Does M1 Finance connect to my existing brokerage account?
No (holds your money at M1). This is the distinction that decides most of the practical experience: a product that holds your money manages it inside its own account, while one that connects to your broker leaves your assets where they are. Neither is better in the abstract, but moving money has tax consequences in a taxable account that connecting does not.
What does the AI in M1 Finance actually do?
Automates rebalancing toward weights you set. That is worth reading literally rather than as marketing, because "AI" spans everything from an automated rebalancing rule to a conversational assistant that reads your holdings. What matters is whether it does the specific job you want done.
What is the biggest drawback of M1 Finance?
Trading happens in scheduled windows rather than on demand, which suits long-term investing and frustrates anyone wanting control over execution. Beyond that: scheduled trade windows mean you do not control execution timing.
Who is M1 Finance best for?
It fits a self-directed investor with a clear allocation in mind who wants it maintained automatically rather than by hand. If that does not describe you, the mismatch will show up quickly, because M1 Finance is built around that use case rather than trying to serve everyone.
M1 Finance vs Betterment: which is better?
They compete in the same category, so the deciding factors are cost and model rather than capability. M1 Finance costs Free tier plus a paid tier (verify current) and holds your money itself; Betterment costs ~0.25%/yr. Betterment leads on set-and-forget automated investing. Compare those before assuming they are interchangeable.
