Key Differences Between M1 Finance and Betterment
ETF Selection and Research Tools
M1 Finance provides access to 1,500+ ETFs with good research tools, while Betterment offers 100+ ETFs with good research capabilities. This gives M1 Finance a meaningful advantage in fund selection, particularly if you want access to niche or sector-specific ETFs beyond the standard broad market funds. Both brokers provide good research tools, so you won't sacrifice analytical capabilities with either choice.
Fractional Shares and Minimum Investment
Both M1 Finance and Betterment support fractional share investing, which is excellent news for beginners who want to start small. You can invest as little as $1 in any ETF on either platform, making it easy to build a diversified portfolio regardless of how much capital you have. This eliminates the need to save up hundreds of dollars just to buy a single share of a popular ETF like VOO.
Trading Costs and Fees
Both M1 Finance and Betterment offer commission-free ETF trading, which has become the industry standard among major brokerages. You will not pay any fees to buy or sell ETFs on either platform. The real cost difference comes down to the ETFs themselves — their expense ratios. Both platforms provide access to the lowest-cost ETFs from Vanguard, Schwab, and iShares, so your costs will depend on which funds you choose rather than which broker you use. Neither platform charges account maintenance fees or inactivity fees, and both have $0 minimum deposit requirements.
Mobile Experience and Usability
Both M1 Finance and Betterment offer mobile apps for managing your ETF portfolio on the go. The quality of mobile experience varies considerably between platforms. M1 Finance (customizable automated portfolios) and Betterment (hands-off automated etf investing) approach design differently. If you plan to primarily manage your investments from your phone, testing both apps before committing is wise. For long-term ETF investors who only check their portfolio occasionally, the mobile experience matters less than research tools and fund selection.
Which Should You Choose: M1 Finance or Betterment?

Our Bottom Line
Overall, we give a slight edge to Betterment (8.5/10 vs 8.3/10) for most ETF investors, primarily because of its strengths in overall user experience and hands-off automated etf investing. However, M1 Finance is the better pick if customizable automated portfolios is your top priority. M1 Finance also offers a wider ETF selection with 1,500+ funds. Remember that the most important decision is not which broker you choose — it is that you start investing consistently and stick with it over the long term.
