M1 Finance vs Betterment: Which Auto-Investing App Wins?
Choosing the right automated investing platform can feel overwhelming when there are so many distinct approaches to wealth building. When comparing m1 finance vs betterment, the choice comes down to how much control you want over your portfolio. While both platforms use automation to help you build wealth, they target entirely different types of investors.
M1 Finance functions as a hybrid broker, allowing you to build custom portfolios of individual stocks and exchange-traded funds (ETFs) that automate according to your target allocations. Betterment, on the other hand, is a pioneer of the traditional robo-advisor model, managing your entire portfolio for you based on your personal goals and risk tolerance.
In this comprehensive comparison, we will break down the features, fees, tax efficiency, and user experiences of both platforms to help you decide which one aligns with your financial strategy.
M1 Finance vs Betterment: Key Differences Explained
At their core, these two platforms represent different investment philosophies. Understanding how they manage your money is the first step in deciding which service fits your financial workflow.
M1 Finance: The Customizable “Pie” Builder
M1 Finance uses a unique visual interface based on “Pies.” A Pie represents your portfolio, and each “slice” represents an individual stock, ETF, or even another pre-built Pie.
You can select up to 100 slices per Pie. Once you set your target percentages (for example, 40% Apple stock, 40% Vanguard S&P 500 ETF, and 20% Tesla stock), M1 Finance automates the purchasing process. Every time you deposit cash, the platform automatically buys fractional shares of your underweight slices to bring your portfolio back toward your target allocation. This is known as dynamic rebalancing.
However, M1 does not offer tax-loss harvesting, and it operates within strict trading windows. Users on the free tier only have access to one morning trading window per day, which means you cannot use M1 for active day trading.
Betterment: The Hands-Off Robo-Advisor
Betterment is designed for investors who want to completely delegate their portfolio management. Instead of picking individual stocks, you answer a series of questions about your financial goals, time horizon, and risk tolerance.
Based on your answers, Betterment builds a diversified portfolio of low-cost ETFs representing up to 12 global asset classes (including US stocks, emerging markets, and municipal bonds). Betterment handles all rebalancing automatically when your asset classes drift from their target weights.
Unlike M1 Finance, Betterment includes advanced automated tax strategies, such as Tax-Loss Harvesting+ (TLH+) and tax-coordinated portfolios, which can help lower your annual tax bill automatically.
Investment Philosophy: Customization vs. Delegation
Your choice between m1 finance vs betterment will likely hinge on how much input you want to have in your daily asset selection.
Customization with M1 Finance
With M1 Finance, you are the portfolio manager. You can choose from over 6,000 individual stocks and low-cost ETFs to build your custom Pies. If you do not want to choose your own assets, M1 offers “Expert Pies” designed for specific goals, such as retirement target dates, socially responsible investing, or sector-specific growth.
Because M1 supports fractional shares, you can invest as little as $1 into any stock or ETF, making it easy to build a highly diversified portfolio even with limited capital.
Delegation with Betterment
Betterment does not allow you to buy individual stocks. Instead, you choose from several curated portfolio strategies:
- Betterment Core: A globally diversified portfolio of stock and bond ETFs.
- Socially Responsible Investing (SRI): Portfolios focusing on environmental, social, and governance (ESG) factors.
- Smart Beta: A quantitative strategy designed to outperform the broader market by targeting specific risk factors.
- Goldman Sachs Smart Beta: A portfolio focused on high-quality corporate bonds and undervalued stocks.
Betterment is strictly goal-oriented. You can set up multiple “buckets” (e.g., “Emergency Fund,” “Retirement,” “House Down Payment”) with different risk profiles, and the platform will manage each bucket according to its specific timeline.
Automation and Rebalancing Comparison
Both platforms excel at automation, but they handle portfolio rebalancing differently.
How M1 Finance Rebalances
M1 Finance uses dynamic rebalancing with every new deposit. If your target for a stock is 20% but it has dropped to 18%, any new cash you deposit will be directed to buy that stock first. This naturally pulls your portfolio back to your target allocation without triggering taxable events (selling assets).
If you want to rebalance your entire portfolio without adding new money, you must manually click the “Rebalance” button. This action will sell overperforming assets and buy underperforming ones, which may trigger capital gains taxes in a taxable account.
How Betterment Rebalances
Betterment uses drift-based rebalancing. The platform continuously monitors your portfolio. If an asset class drifts by more than a specific percentage (usually 3% to 5%) from its target allocation, Betterment automatically sells overperforming assets and buys underperforming ones to restore balance.
This process is entirely automated and runs in the background. While selling assets can trigger capital gains, Betterment uses tax-minimization algorithms to sell shares with the lowest tax impact first.
Tax Efficiency: How They Compare
Tax optimization can have a massive impact on your net returns over long investment horizons. Here is how these platforms stack up on tax efficiency.
| Tax Feature | M1 Finance | Betterment |
|---|---|---|
| Tax-Loss Harvesting | No (Manual tax-efficient selling only) | Yes (Automated Tax-Loss Harvesting+) |
| Tax-Coordinated Portfolios | No | Yes (Asset location optimization) |
| Tax-Efficient Selling | Yes (Tax-minimization algorithm) | Yes (FIFO/LIFO tax-smart lot selection) |
Betterment’s Tax Edge
Betterment is the clear winner for taxable accounts due to its automated Tax-Loss Harvesting+ (TLH+). This feature automatically sells ETFs that have experienced a loss to offset capital gains and up to $3,000 of ordinary income. It then immediately buys a highly correlated, similar ETF to maintain your portfolio’s market exposure without violating the IRS wash-sale rule.
According to historical data published by Betterment, tax-loss harvesting can add an estimated 0.77% in annual post-tax returns, though individual results vary based on tax brackets and market volatility.
Additionally, Betterment offers Tax-Coordinated Portfolios. This strategy places dividend-heavy assets (like bonds) into tax-advantaged accounts (like IRAs) and growth-oriented assets into taxable accounts, optimizing your overall tax burden.
M1 Finance’s Tax Strategy
M1 Finance does not offer automated tax-loss harvesting. However, it does use a tax-minimization selling algorithm. When you request a withdrawal or manually sell assets, M1 automatically sells shares in an order that minimizes your tax liability:
- Losses that offset gains (Short-term or long-term losses)
- Long-term gains (taxed at lower rates)
- Short-term gains (taxed at higher ordinary income rates)
While this helps reduce the tax impact of manual sales, it does not actively harvest losses to offset other income throughout the year.
Platform Fees and Costs
Understanding the fee structure of both platforms is crucial, as fees directly compound over time and reduce your overall returns.
Betterment Fees
Betterment charges an annual management fee based on your account balance:
- Betterment Digital: Charges a 0.25% annual fee on your balance. For accounts under $20,000, this fee is a flat $4/month unless you set up a monthly recurring deposit of at least $250.
- Betterment Premium: Charges a 0.40% annual fee and requires a $100,000 minimum balance. This tier grants you unlimited access to Betterment’s team of Certified Financial Planners (CFPs) for personalized advice.
M1 Finance Fees
M1 Finance operates on a flat platform fee model rather than an asset-under-management (AUM) percentage:
- Accounts under $10,000: Users pay a flat $3 monthly platform fee.
- Accounts of $10,000 or more: The platform fee is waived ($0/month).
- M1 Personal Loan users: The fee is also waived if you have an active personal loan through M1.
For investors with larger balances, M1 Finance is incredibly cost-effective. A $100,000 portfolio at Betterment costs $250 annually, whereas the same portfolio at M1 Finance costs $0 per year.
Additional Features: Borrowing, Banking, and Crypto
