M1 Finance Review (2026): Robo-Advisor Fees and Who It Suits

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 through new contributions instead of sales. Trades execute in one or two daily windows, which is the design trade for the automation and the fractional-share support.

In category terms it is a robo-advisor (hands-off automated investing), 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.

• 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.

Trading happens in scheduled windows, 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 and gives no advice, so nobody is telling you whether your Pie is sensible

M1 charges a $3 monthly platform fee, waived once you hold more than $10,000 on the platform. A paid M1 Plus tier exists; check its current price on m1.com. Checked on m1.com, October 2026. 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 point-in-time guide, and the M1 Finance pricing breakdown goes into what else you pay on top. Confirm current pricing on M1 Finance's own site.

Prices checked October 2026. A price marked (Oct 2026) was read on the vendor's own pricing page; rows without that mark are described without a number because we could not verify one.

The two columns that change your experience most are whether your money has to move and whether the tool can act on what it finds. Cost matters next, and only in dollars.

M1 Finance holds your money in its own account and manages it for you. Walnut is an AI investing app: it connects the brokerage you already use, read-only by default, gives each stock you hold a keep, trim or exit read against the S&P 500, and places the trades you approve. Your money stays where it is. Walnut is free to use, with no fee on assets; Walnut Plus ($9.99 a month on the web) lifts the assistant's session limit.

The limits, with the job Walnut does own beside each: it does not manage money on autopilot, but it drafts the trades back to your target weights and places the ones you approve; it has no cost basis or tax lots and does not harvest losses, so it reads each holding by its one-year price return against the S&P 500; and it works on a brokerage account you already hold and does not open one for you. If you want the whole portfolio run for you, M1 Finance does that job; Walnut covers the stocks you pick yourself. The full self-assessment is on the Walnut review.

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; $3/mo platform fee unless you hold $10,000+ (Oct 2026). It fits a self-directed investor with a clear allocation in mind who wants it maintained automatically. The trade-off to accept: Trading happens in scheduled windows, 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.

We compared M1 Finance with the products answer engines most often set beside it (Betterment, Wealthfront, Magnifi, PortfolioPilot, Danelfin) and with Walnut, on five questions: where your money sits, whether the tool reads the account you already have, whether it can place a trade, what it costs in dollars, and who it fits. Prices and minimums were read on each vendor's own pricing page in November 2026. Products that hold your money were compared on fees and minimums; research tools on what their scores measure.

Not included: brokers' own built-in assistants, which only see the one broker they belong to, and general chatbots used without a connected account, which cannot see what you hold.
