Getting started with investing can be overwhelming. You probably realize it’s something that can help you build wealth, but where do you begin?

There are actually apps that are a great option for new investors. They make it easy to get comfortable with investing since they only require small amounts of money.

Here are some of the best micro-investing apps to help you get started with investing.

What is Micro-Investing?

Micro investing is where you can invest a small amount of money and get started with as little as $1.

There are many apps that allow you to buy fractional shares of companies, so lets say you want to buy a stock that has a stock price of $2000, you can actually invest $1 in to the same company and own 1/2000 of a share.

This is great because pretty much anyone can invest in the stock market without having a lot of money.

Top Micro-Investing Apps

When it comes to investing, starting small means you can build your comfort levels and learn about your personal risk tolerance. You can take it slowly and work up to larger investments over time.

This is better than making a big investment at the get-go that makes you uneasy or results in a financial loss. 

These micro investing apps can help you get started. 

1. SoFi Active Investing

Sofi Active Investing home page

Of the apps in this list, SoFi boasts the most features. This makes it a great option for new and experienced investors. 

You can open an account for free, make free trades and not worry about account minimums. 

SoFi checks all of the boxes when it comes to easily opening investment accounts and investing small amounts of money in fractional shares. That said, they also provide other financial services. 

With SoFi, you can:

  • Open cash management accounts 
  • Have access to debit and credit cards
  • Apply for loans
  • Refinance student, personal and home loans

It’s important to note that all of SoFi’s services can be used independently. This is ideal for someone who might need one service now, like investing, but may require additional services in the future. 

Investing for specific goals in an individual brokerage account and for your retirement are both possible at SoFi. Investing in cryptocurrencies is another possibility. 

One downside of SoFi is that it does not allow you to open custodial accounts and invest on behalf of your children.

Best for: New and experienced investors interested in other financial services

Fees: None

2. M1 Finance

M1 Finance home page

M1 Finance is another great free investing app offering stocks, ETFs and premade investment portfolios. Buying is easy with the option to buy fractional shares or full. Plus you can assign targets, limits, stops and more.

Taxable accounts start at $100 minimum. IRA retirement accounts start with a $500 minimum. Subsequent investments only require $25 yet you can buy multiple stocks with each trade.

How you build a portfolio with M1 Finance is different than most investing apps. Instead of deciding how many dollars to invest in a stock, you assign a target percentage. Like building a pie one piece at a time.

Some of the best features are:

  • Dynamic rebalancing: The brokerage automatically buys shares of your holdings currently below their target allocation. Automatic rebalancing doesn’t sell shares of overallocated holdings until you request a manual rebalance or decide to close a position.
  • Premade pies: In addition to indiviudal stocks and ETFs, you can add expert pies for a variety of investment strategies. Some of these pies mimic robo-advisors but you won’t pay any annual advisory fees.
  • M1 Plus: A premium membership program giving you access to an afternoon trading window, automated investing rules, custodial accounts and other banking perks. The annual membership fee is $125.

Best for: Scrupulous investor that likes to build their own self-directed portfolio.

Fees: None

3. Acorns

Acorns home page

Acorns was one of the first apps that offered micro investing to hit the market. This platform is known for rounding up your purchases and investing the difference in your investment account. 

The great thing about Acorns is that they provide an all-in-one solution for new investors. They have a checking account with a debit card that will automatically round up your purchases each time you use it. 

For example, if you’re at the grocery store and swipe your Acorns card for a $47.62 purchase, that amount will be rounded up. Then, your 38 cents of change will be deposited into your Acorns account.

Acorns also has recurring, automatic investments with a $5 investment minimum. This means that you can set up larger deposits into your retirement accounts.

Acorns monthly plans:

  • $3 for Personal: Invest spare change, get a debit card, money advice and more 
  • $5 for Family: Access accounts for kids, exclusive content and more 

If you decide to change or cancel your plan, it’s easy to do since plans are on a month-to-month basis.

As a result of its hassle-free and automatic approach to investing, Acorns is one of the most popular micro investing apps on the market.

Best for: Beginners who want a simple, all-in-one investment solution. 

Fees: $3 – $5 per month
