How Does M1 Finance Make Money? | Revenue In Plain English

M1 Finance earns revenue from interest, platform fees, securities lending, order flow, cash spreads, and account fees.

M1 Finance looks simple from the outside: build a Pie, fund it, let auto-invest do the routine work. The business behind that clean screen is less mysterious because the account can create revenue in several quieter places.

The main idea is this: M1 earns when users hold cash, borrow against portfolios, trade through routed orders, keep securities that can be lent, or pay platform and account charges.

How M1 Finance Makes Money From Everyday Accounts

M1’s public materials describe a mix of revenue streams tied to brokerage, cash, lending, and fees. That mix matters because “free trading” doesn’t mean the company has no revenue. It means the charge is not placed on each basic stock or ETF order.

For users, the tradeoff is plain. You may pay little or nothing for normal investing activity, but the company can still earn around the account. That includes idle brokerage cash, margin balances, order routing, fully paid securities lending, and monthly charges when account conditions don’t remove them.

Cash Balances And Sweep Income

Cash is one of the simplest revenue streams. When cash sits in certain M1 accounts, banks or brokerage partners may pay interest on that cash. M1 may keep part of that spread, while users receive the posted rate where a cash yield applies.

This is common in brokerage and cash programs. The gap between what the bank pays and what the user receives can become revenue. In M1’s own Form CRS, it says High-Yield Cash Account rates are based on amounts paid by program banks, less a fee paid to M1.

Platform And Account Fees

M1 also charges certain direct fees. Its disclosure materials list a monthly platform fee for clients who don’t meet program requirements, along with charges tied to certain account actions. Those fees can include paper document requests, outgoing transfers, wire activity, and some retirement account charges.

These fees don’t hit every user. They tend to show up when an account falls outside fee-waiver rules or when the user asks for a service that costs the firm extra work. That is why fee schedules matter.

• Read the fee schedule before opening an account.
• Check whether assets, loans, or other program rules remove monthly charges.
• Watch transfer, paper, wire, and retirement account fees before moving money.

Order Routing And Payment For Order Flow

M1 routes trades during set trading windows. For some orders, the executing venue may pay M1 for sending order flow. This is payment for order flow, often shortened to PFOF.

The revenue is not a visible trade commission, but it still creates a conflict to understand. Regulators require broker-dealers to disclose routing practices, and the SEC Rule 606 FAQ explains public reporting duties around order routing and payments. M1 says it receives payment for order flow and is paid based on share amounts sent to certain execution venues.

Margin Loans

Margin is another direct revenue source. When a user borrows against eligible securities, the broker charges interest. M1 can earn the spread between its own funding cost and the rate paid by the borrower.

This can be attractive for users who want liquidity without selling shares, but it adds risk. M1’s revenue rises when more users borrow, but the user’s cost rises each day the loan remains open.

Revenue Stream	How M1 Gets Paid	What Users Should Check
Brokerage Cash	Earns from idle cash or spread arrangements	Cash yield, sweep terms, and unpaid cash rules
High-Yield Cash	Keeps a fee or spread from bank-paid amounts	Current APY, bank sweep details, FDIC limits
Platform Fee	Monthly charge when waiver rules are not met	Assets, loan status, and fee-removal rules
IRA Fee	Monthly retirement account fee in certain cases	Balance level and whether platform fee status removes it
Order Flow	Receives payment from execution venues	Routing reports, trade windows, and execution quality
Margin Loans	Charges interest on borrowed money	Rate, collateral rules, and margin call risk
Securities Lending	Lends eligible fully paid shares and keeps most revenue	Enrollment, tax treatment, voting rights, and opt-out rules
Account Actions	Charges for transfers, wires, paper records, or special tasks	Fee schedule before requesting account changes

Why Zero-Commission Trading Still Pays M1

Zero-commission investing works because the trade ticket is not the only place money changes hands. M1 can earn from the account’s cash, the order’s route, the borrowed balance, and the securities sitting in the portfolio.

That doesn’t make the model bad by default. It does mean users should know where incentives sit. A platform can be low-cost for a hands-off investor and still be profitable for the company.

Securities Lending Revenue

Fully paid securities lending lets M1 lend eligible shares that a user owns outright. Borrowers may need those shares for short selling, trade settlement, or other market activity. The borrower pays a fee, then M1 shares part of that revenue with the user.

M1’s fully paid securities lending page states that enrolled users earn 10% of revenue generated from lending their shares. That means M1 keeps the rest. The user still has market exposure, but voting rights can shift while shares are on loan, and substitute dividend payments may receive different tax treatment.

Fractional Shares And Trade Windows

M1’s Pie system often creates fractional-share trades. M1 says that in limited cases it may fill a fractional share order from its own inventory account. It also says the trade price matches the average price received and does not include a markup or commission, though M1 could benefit.

The trade-window system is part of the business design. It reduces constant order handling and fits M1’s long-term account style. Users who want second-by-second trade control may not like it, but users who automate deposits may find it enough.

Where The User Pays Most Directly

The clearest user-paid costs are not hidden. They are account fees, margin interest, and charges for special actions. The less visible revenue streams are cash spreads, order flow, and securities lending.

User Action	Possible Cost Or Tradeoff	Practical Check
Holding Idle Cash	M1 may earn a spread	Compare the posted cash rate with other cash options
Borrowing On Margin	Daily interest and possible margin call	Borrow less than the max and track collateral
Using Auto-Invest	Orders run in windows, not on demand	Decide whether timing flexibility matters
Enrolling In Share Lending	Revenue split, voting shift, tax wrinkle	Read the lending terms before staying enrolled
Moving Or Closing Accounts	Transfer or service fees may apply	Check the fee schedule before moving assets

Is M1’s Business Model Fair For Investors?

It works best for people who want automated deposits, fractional-share allocation, and low routine trading costs. It works less well for users who want instant execution, lots of manual trading, or zero exposure to order-routing incentives.

The fairest way to judge it is by your own behavior. A user who holds cash, borrows on margin, moves accounts often, or keeps securities lending turned on may create more revenue for M1. A user who invests steadily, avoids margin, keeps enough assets to meet fee rules, and checks disclosures may pay little directly.

What To Check Before Opening Or Keeping An Account

Use the revenue model as a checklist. The better question is whether the costs and tradeoffs match how you invest.

• Review the current Form CRS and fee schedule.
• Compare margin rates before borrowing.
• Check whether share lending is active on your account.
• Read routing disclosures if execution quality matters to you.
• Watch cash balances so idle money is not working harder for M1 than for you.

A Clear Read On M1’s Revenue Model

M1 Finance makes money through a bundle of small and large revenue streams instead of a single trade commission. The biggest areas to understand are cash spreads, platform and account fees, payment for order flow, margin interest, and fully paid securities lending.

For a long-term, automated investor, that model can still be low cost. For a margin borrower, frequent mover, or user with large idle cash, the cost picture can change. Read the disclosures, match them to your habits, then judge the tradeoff.
