M1 Finance vs. Interactive Brokers – Summary Comparison
M1 Finance will be much easier to navigate than Interactive Brokers for novice investors. If you don't need all-day trading and if you want access to automatic rebalancing, M1 Finance is the better choice.
Interactive Brokers has some of the lowest fees and cheapest margin rates in the game. Unfortunately, their interfaces and mobile apps are severely lacking. If you are a day trader and need order control, go with Interactive Brokers over M1 Finance.
M1 Finance vs. Interactive Brokers – Fees and Commissions
For U.S. investors, in relation to U.S. exchange-listed stocks and ETF’s, both M1 Finance and Interactive Brokers have zero commissions and zero account fees.
M1 Finance vs. Interactive Brokers – Account Types
M1 Finance offers taxable, Joint, Traditional IRA, Roth IRA, Rollover IRA, SEP IRA, Trust, and Custodial (M1 Plus members) accounts. They currently do not offer SIMPLE IRA, 401(k), Solo 401(k), 529, HSA, or Non-Profit accounts.
Interactive Brokers offers the exact same accounts with their IBKR Lite plan.
Note that M1 Finance is only available to U.S. customers. Interactive Brokers is available to customers in multiple countries.
M1 Finance vs. Interactive Brokers – Mobile App
M1 Finance has a sleek, intuitive, user-friendly, robust mobile app for both Apple iOS and Android:
According to users, the mobile apps of Interactive Brokers seem to be notoriously buggy and not well-supported. Here are some screenshots of the app:
M1 Finance vs. Interactive Brokers – User Interface
To be frank, the Interactive Brokers interface is downright awful and antiquated. It will be especially confusing for a beginner investor. I would argue Interactive Brokers is definitely only suitable for sophisticated, seasoned investors and traders. Their user interface looks like this:
The interface for M1 Finance, on the other hand, is extremely simple and intuitive with its pie-based visualization, and is perfect for beginner and seasoned investors alike:
M1 Finance vs. Interactive Brokers – Customer Service
IB’s customer service is not horrible but not great. Customer service from M1 is comparable. Positive and negative anecdotes exist for both brokers. I’d say it’s a tie.
M1 Finance vs. Interactive Brokers – Minimum Deposit
Both Interactive Brokers and M1 Finance have no minimum deposit required.
M1 Finance vs. Interactive Brokers – Investment Products
Interactive Brokers is more suited for traders and allows the trading of stocks, ETF’s, options, and futures contracts, as well as forex, among other things.
M1, on the other hand, doesn’t have these things, and is better suited for long-term buy-and-hold investors of stocks and ETF’s. M1 offers most stocks and ETF’s listed on major exchanges.
M1 Finance vs. Interactive Brokers – Extra Features
Interactive Brokers doesn’t provide access to an integrable checking account like you can get with M1 Finance via M1 Spend. With their premium M1 Plus option, you can earn interest and cash back on that checking account.
Interactive Brokers has much more charting and technical analysis tools, albeit in a clunky interface. M1’s offerings here are pretty simple, but again, M1 is not designed for traders.
IB also doesn’t employ M1’s famous “dynamic rebalancing,” which strategically allocates new deposits to maintain your portfolio’s target allocations.
M1 Finance vs. Interactive Brokers – Margin
Margin rates between Interactive Brokers and M1 Finance are pretty similar. Both are extremely low. Margin rates are as follows for a $100,000 margin loan:
- IB Lite – 2.55%
- IB PRo – 1.55%
- M1 Finance – 3.50%
- M1 Plus – 2.00%
Perhaps the most important difference though is the fact that margin from Interactive Brokers can only be used to leverage your portfolio with them (i.e. buy more securities), whereas a margin loan from M1 Finance can be used for whatever you want – refinancing higher-interest debt, major purchases, unexpected expenses, etc.; it’s just a low-interest collateralized loan.
M1 Finance vs. Interactive Brokers – Summary and Conclusion
- Both IB and M1 have no minimum deposit requirement.
- Both IB and M1 offer commission-free trades and zero account fees for U.S. investors buying stocks and ETF’s.
- M1 Finance and Interactive Brokers offer the same account types.

- Similarly, Interactive Brokers has a notoriously bad and buggy mobile app. The M1 Finance mobile app is sleek, intuitive, and robust.
- Customer service should be comparable between the two.
- IB offers some extra securities for traders like options, futures, and forex. M1 only offers stocks and ETF’s.
- IB, being better suited for trading, has more charting and analysis tools than M1.

- Margin rates between the two are roughly comparable, but M1’s margin loan can be used for anything you want.
I think M1 Finance slightly edges out over Interactive Brokers for the average retail investor due to the reasons above. Obviously, if you’re a sophisticated, active trader looking for a day trading platform, go with Interactive Brokers. If you’re simply looking for a platform for long-term, buy-and-hold investing, go with M1 Finance.
