Looking for a logical way to get started with investing? If you only have a few dollars to spare, then you may be interested in micro-investing. With lots of options for automation, plus user-friendly trading platforms, micro-investing can feel like a no-brainer—and the magnitude of the financial benefits might surprise you.

　　Investing isn’t just for rich folks and professionals, especially now that technology enables so many micro-investing apps. Let’s explore micro-investing and how it works.

　　What is micro-investing?Micro-investing means investing small amounts of money, often on a recurring basis, and typically using an app to automate the process. If your budget is tight or you’re feeling especially risk averse, micro-investing may serve as a viable entry point to building personal wealth. And it’s possible to accumulate invested capital gradually if you start with micro-investing. Let’s take a look at the key features of micro-investing.

　　Low minimum investment requirementsMicro-investing is defined by making contributions in small dollar amounts. Investments as low as $1 or even just the spare change from everyday purchases can be applied toward micro-investing. Buying fractional shares of stocks may also be classified as micro-investing.

　　Varied fee structuresMicro-investing platforms typically charge a fee, which can take many forms:

　　Fixed monthly fee. Some platforms charge a flat monthly rate, which may vary depending on the subscription tier.Management fee. Automated investing advisory platforms—aka “robo-advisors”—may assess a fee based on the value of your assets under management.Transaction fees. You may be assessed a fee for every micro-investing transaction, although per-transaction fees are becoming less common.Automated investingA core feature of many micro-investing apps is the ability to automate your investments. Recurring investments—perhaps using a dollar cost averaging strategy—may be automatically funded by your bank account, or you can use a roundup feature that automatically “keeps the change” from your credit or debit card purchases. That change from every purchase is applied to your micro-investing strategy.

　　Diversified investment optionsMicro-investing can provide you with access to a diverse range of investment types, including stocks, bonds, exchange-traded funds (ETFs), and real estate investment trusts (REITs). There are also other ways to diversify your micro-investing approach:

　　By market cap. You can buy fractional shares of small-cap, mid-cap, and large-cap companies.By sector. Want to focus on technology, health care, or any of the 11 market sectors and the industries within them? You can.By geography. Invest domestically and internationally. By strategy. Use a mix of micro-investing platforms, including robo-advisors.Invest in your valuesMicro-investing is strongly linked with socially responsible or impact investing. That’s because everyone can benefit from low investing thresholds and increased access to capital. Some platforms enable you to direct your micro-investments; for example, you might support low-income entrepreneurs who require little capital to start their microbusinesses.

　　Plenty of educational toolsMany micro-investing apps are loaded with learning tools and information. These educational resources can increase your financial literacy while you’re gaining practical investing experience.

　　User-friendly experiencesMicro-investing without the support of an app or other platform would be tedious or impossible. You can expect micro-investing apps to provide a user experience that’s friendly and perhaps even educational and fun.

　　How to get started with micro-investingThe process of micro-investing has much in common with investing larger sums. That’s because no matter the dollar amount, your investing activities should align with your financial goals.

　　Consider your investing goals. Why are you interested in micro-investing? What are your motivations for getting started? Your first step is to consider and define your objectives.Research micro-investing apps. You have lots of choices for micro-investing platforms, and you don’t have to pick just one. Aim to align your choice of platform(s) with your micro-investing goals and broader money objectives. Choose a platform. Your next move is to choose a micro-investing app and install the software. You’ll need to create an account and provide identifying information. You’ll also need to link a funding source, such as your bank account, to get started using a micro-investing platform. Specify your investment preferences. Now you get to put your investment plan into action. Use the app to make investment choices and set up any automations that make micro-investing easier for you. Start micro-investing. After you’ve confirmed that your investment settings are correct, you’re ready to officially begin micro-investing. If you’ve enabled roundups, for example, then you can expect that your next electronic purchase will be rounded up to fund your first micro-investment. Monitor and adjust as needed. Micro-investing may be automated, but it’s not something you should set and forget. You’re responsible for continuing to monitor your micro-investments, because if you’re not paying attention, you won’t be making key adjustments when they’re needed.A partial list of micro-investing appsMany micro-investing apps are developed by financial technology (fintech) companies. But traditional brokerage firms and robo-advisors also support micro-investing.

And using your limited funds to invest in social impact—should you choose that path—can help you align your financial and social objectives. But however you invest, make sure to approach micro-investing responsibly by first defining your money priorities and then looking through fund prospectuses and/or company fundamentals. Even small investments can produce outsize returns over time if you start with micro-investing and eventually scale up.
