Our view

In years past, you needed hundreds of dollars to start investing and could expect hefty commission fees. Today, you can start investing with very little money.

Two popular investing platforms are M1 Finance4 and Stash, both of which offer low-cost investing and allow you to buy stocks and ETFs with zero trading fees5. Both of them also made our list of the best investment apps. But Stash is better suited to new investors with less to invest, while M1 is better suited to more experienced, hands-on investors.

In this comparison of M1 Finance6 vs. Stash, you'll learn how they differ from each other and how to choose which is best for you and your personal finance goals.

How does M1 Finance work?

M1 is a money management app that offers investment, banking, and borrowing options. It has a relatively modest monthly fee of $3, and that can be waived with a balance of $10,000 or more at least once during a billing cycle or if you have a personal loan with M1. With its investment product, you can buy into individual stocks or exchange-traded funds (ETFs) and construct a personalized investment portfolio to meet your needs and risk tolerance. M1 Finance offers expert-selected investment pies as well. These are carefully curated portfolios with different asset allocations based on your risk tolerance.13

With M1 Finance, you can also invest in fractional shares or partial shares of assets. This helps you to maximize every dollar you contribute rather than having money sit in your account until you have enough to buy an entire share, and it allows you to diversify more with less invested.

M1 Finance is best for long-term investing, as it has limited investment windows. To keep its costs low, M1 Finance allows users to trade during only two windows14, a time when assets can be bought or sold.

Other platforms offer many more trading windows, making it easier to buy and sell stocks at competitive prices. Because of its limited trading windows, M1 Finance is not designed for day trading. If that is something you're interested in, you're better off investing money with another service, like Robinhood or E*TRADE.

How does Stash work?

With Stash, you can begin investing with as little as $1. In addition, Stash offers robust educational tools and resources to help you invest more confidently, and it stands out from other investment platforms for building in more automated investment options so you can invest more.

Stash membership plans and pricing

There are two different Stash membership levels:

  • Stash Growth: Stash Growth costs $3 per month. With this membership, investors can purchase fractional shares in a personal investment account and get access to a bank account. You can also get your paycheck up to two days early with direct deposit15, and get up to $1,000 in life insurance16. You also can invest in individual retirement accounts (both traditional and Roth IRAs).
  • Stash+: If you opt for a Stash+ membership, which costs $12 per month, you get all the benefits of Stash Growth plus two investing accounts for children. You'll also earn 1% Stock-Back® rewards17 when you spend on eligible purchases with the Stash debit card, and you'll get $9,000 of additional life insurance coverage ($10,000)16.

With Stash's investment app, you can invest in stocks and ETFs. You can open a taxable account, IRA, or custodial account. When you invest, Stash will ask you several questions and then give you recommendations. Stash allows you to purchase fractional shares, so your contribution is invested right away. When you enable Round-Ups, Stash will automatically round up transactions from your linked funding account to the nearest dollar and transfer the extra to your investment account.

Investors will also have the option to invest in Stash's Smart Portfolio. These carefully designed portfolios enable you to be diversified and regularly invest in your portfolio without having to make all your own investment decisions. Stash will also rebalance your portfolio for you, as well as reinvest your dividends.

Stash also offers online banking and has a debit card12 you can use to earn more shares of stocks. With Stock-BackⓇ rewards — available at both membership levels — you'll earn pieces of stock when you make eligible purchases at your favorite retailers.18 

Stash is best for beginner investors who don't want to wait to start investing until they have hundreds or thousands saved.

Which investment platform should you choose?

When you should choose M1 Finance

If you want to invest in ETFs

For many investors, ETFs are a smarter option than individual stocks. When you invest in ETFs, you're investing in hundreds of stocks or bonds at once. This increases the diversification in your portfolio, which might help you navigate the market more successfully. If one company within your ETF portfolio falls in value, other companies may offset your losses.

Although Stash does allow you to invest in ETFs, its list of ETF options is comparatively limited; it has more of a focus on individual stocks. M1 Finance has more than 6,000 stocks and ETFs to invest in, giving you more options.

You want access to expert-selected portfolios

As a new investor, you might not know what portfolio allocation to choose or how to pick stocks or ETFs. If you want expert help, M1 Finance is a better option for you.

M1 Finance offers expert pies, professionally designed portfolios that are created to meet your financial goals and risk tolerance. Or you can opt to invest in certain industries, such as health care or technology.

When you should choose Stash

You want to take advantage of Round-Ups and other automated investment features

When you're just starting out, it can be difficult to budget money for investing. Stash makes it simple. When you turn on stock round-ups19, it rounds up any purchase made with the Stock-Back® Card, and your spare change is invested into a stock that matches your purchase (or a custom investment, if no stock match is available).1 With this strategy, you can invest money without thinking much about it, and your money can potentially earn returns over time.

You have less money to invest

With M1 Finance, you need a minimum balance of at least $100 to open a taxable investment account, and $500 to open an IRA. For some, coming up with that much money can be a big hurdle to investing. If that's the case for you, Stash can be a useful alternative. With Stash, you can start investing with just $1.

What both M1 Finance and Stash excel at

M1 Finance and Stash have several features in common that make them valuable for investors:

  • No add-on commission fees: Although traditional investment firms charge commissions, neither M1 Finance nor Stash charge any commissions on trades. Without commissions, you get to keep more of your returns.
  • Fractional shares: Both M1 Finance and Stash allow you to purchase fractional shares, rather than forcing you to wait until you have enough money to purchase a full share.
  • Educational resources: For new investors, both investment apps have educational resources and tools to help you learn the basics of investing.

6 important differences between M1 Finance and Stash

While both M1 Finance and Stash are two of the best investment apps, they differ in several key ways:

  1. Membership fees: M1 costs $3 per month with options to waive, whereas both of Stash's accounts have monthly membership fees. If you're looking for a low-cost but fully-featured option, M1 Finance has the edge over Stash.
  2. Curated portfolios: With Stash, your investment options are limited with fewer curated portfolios. M1 Finance has expert pie options and thousands of ETFs you can invest in, which makes it a good choice if you're not sure where to start.
  3. Round-Ups: Stash's Round-Ups feature allows you to round up18 purchases and invest the spare change when you use the Stock-Back® Card. Over time, those small investments can add up. M1 Finance doesn't offer this kind of automated investing feature.
  4. Investment options: When it comes to investment options, M1 Finance has more to choose from than Stash. With M1 Finance, you can invest in more than 6,200 stocks and ETFs, as well as cryptocurrency. Stash offers over 3,000 stocks and ETFs.
  5. Automated rebalancing: M1 Finance has automatic rebalancing, updating your portfolio to match your goals and risk tolerance. With Stash, you have to rebalance your portfolio yourself unless you invest in its Smart Portfolio.
  6. Stock-Back® program: When you use a Stash Stock-Back® Card12 at retailers, you can earn stock back with every eligible purchase19, helping you build your portfolio. This is a feature unique to Stash; M1 Finance doesn't have anything similar.

FAQs

Is M1 Finance trustworthy?

All investments have a level of risk, so it's important to be careful when investing your money. M1 Finance is a legitimate, trustworthy company. M1 Finance is a brokerage firm regulated by the Financial Industry Regulatory Authority, and it's been registered with the U.S. Securities and Exchange Commission since 2016.

Money you invest with M1 Finance is protected via Securities Investor Protection Corporation insurance. SIPC covers up to $500,000 that you invest. However, SIPC insurance provides protection only if the brokerage firm fails. It does not protect you from investment declines and losses from the stock market's performance.

Can you actually make money on Stash?

As with M1 Finance, Stash is an investment and savings app. Money you invest could potentially grow over time. For example, let's say you invested $500 when you turned 25. After that, you invested $50 per month until you reached 67. By the time you turned 67, you would contribute $25,200. But thanks to the stock market's returns — assuming an 8% annual return — your account could be worth $220,259.

However, investing isn't a guarantee you'll earn money. When you invest, you have the potential for returns — but you also could lose money. There's no guarantee your investments will grow, so only invest money you don't rely on for necessary expenses. If you have questions about investing, consider seeking out professional financial advice.

Is M1 Finance or Stash better for beginners?

For beginners who aren't sure what investment choices to make, M1 Finance is likely the better option. Although it requires a larger minimum investment than Stash, it operates like a robo-advisor in some ways. Its expert pies allow you to start investing without picking stocks or ETFs yourself and doesn't charge monthly fees. Its professionally designed portfolios are created to match your comfort with risk and financial goals, and it rebalances automatically.

How do M1 Finance and Stash make money?

M1 Finance makes money through interest, including money it earns on loans to customers, its $3 per month platform fee, and lending out securities. Stash makes money through its monthly membership fees, charging $3 to $12 per month.

What are some alternatives to M1 Finance and Stash?

While M1 Finance and Stash are both great choices, if they don't sound quite right, you have plenty of other options to consider:

  • Acorns: Acorns is a robo-advisor that's worth considering if you prefer a more hands-off approach to investing. You also have the option to open custodial accounts for your children with an Acorns Family Plan.
  • Betterment: Betterment is a robo-advisor as well, but it offers the opportunity to connect with a team of financial advisors with its Premium plan and advice packages.
  • Robinhood: If you're interested in managing your own portfolio, Robinhood could be a good choice. It also gives you the option to invest in cryptocurrency.
  • Wealthfront: Like Acorns and Betterment, Wealthfront is also a robo-advisor. However, this platform also offers the option to invest in a 529 college savings plan.  

Bottom line

Both of these investment platforms offer mobile apps for both Android and iOS devices. When comparing M1 Finance vs. Stash, the biggest difference is in their pricing. The M1 Finance basic account is free, and Stash's accounts require a monthly membership fee.

If you are looking to invest and trade stocks and ETFs without paying commissions or account fees, M1 Finance is the clear winner. However, M1 Finance does have a comparatively large account minimum to get started. If you're looking for an app that allows you to invest without thinking about it, Stash's Round-Ups feature is a great benefit, allowing you to invest your spare change.

Regardless of which you choose, both investing apps are user-friendly tools that can help you get started on a path to responsible investing without a significant amount of money or a great deal of investing knowledge, making them good options for beginners.
