I Tried Micro Investing for 90 Days—Here’s What I Learned

Introduction: Why I Decided to Try Micro Investing

I’ve always been curious about investing, but the idea of putting large amounts of money into the stock market intimidated me. I didn’t have thousands of dollars lying around, and I certainly wasn’t ready to risk losing money I couldn’t afford to part with. That’s when I stumbled upon the idea of micro investing—a method that allows you to invest small amounts, sometimes even just your spare change. The concept seemed almost too good to be true, so I decided to take it seriously. I tried micro investing for 90 days—here’s what I learned.

 

 

What Is Micro Investing?

Before diving into my personal experience, it’s important to understand what micro investing actually means. Micro investing is a type of investment strategy that enables users to invest small sums of money regularly. Most micro investing platforms work via mobile apps that link to your bank account or credit card. Whenever you make a purchase, the app rounds up the total to the nearest dollar and invests the difference.

For example, if you buy a coffee for $3.45, the app rounds it up to $4.00 and invests the $0.55. It sounds small, but over time, these tiny contributions can add up—especially if you're making multiple transactions per day.

 

 

Getting Started: Choosing a Platform

There are several popular micro investing platforms on the market—Acorns, Stash, Robinhood, and SoFi, to name a few. I chose Acorns because of its user-friendly interface, automatic round-ups, and the fact that it offered a diversified portfolio managed by experts.

After downloading the app and linking my bank account, I set up a recurring investment of $5 per week in addition to the round-up feature. I also filled out a short risk-assessment quiz, which determined that a moderate risk portfolio was best suited for my goals.

 

 

The First 30 Days: Building the Habit

In the first month, I barely noticed the money being deducted from my account. That’s one of the advantages of micro investing—you don’t feel the pinch. I made roughly 60 transactions during this period, and the spare change from these purchases added up to around $22. Combined with my recurring $5 weekly investments, I had about $42 in my portfolio by the end of the month.

During this initial phase, I focused more on building the habit rather than tracking gains or losses. One thing I appreciated was how the app broke down the types of investments I owned—some money was in large-cap stocks, some in bonds, and a small portion in real estate investment trusts (REITs). Seeing this made me feel more like an actual investor.

 

 

Days 31–60: Market Fluctuations and First Lessons

By the second month, I had invested over $80, and I started to see the effects of market volatility. My portfolio value dipped by about 4% due to a temporary market downturn. Initially, I felt concerned. Was this whole thing a bad idea? But then I remembered that investing is a long-term game.

This part of the 90-day journey taught me my first real lesson: don’t panic over short-term losses. The beauty of micro investing is that you’re not risking a large sum. Even when the market drops, your losses are relatively small in absolute terms, which makes it easier to stay calm and stay invested.

I also began reading more about the principles of long-term investing. Terms like “dollar-cost averaging,” “compound interest,” and “diversification” started to make more sense. These small, regular investments were essentially training me to think like a disciplined investor.

 

 

Days 61–90: Gaining Confidence and Thinking Bigger

In the final month, I felt a noticeable shift in my mindset. I was no longer investing passively—I was actively checking market news, comparing ETFs, and reading up on personal finance blogs. My portfolio bounced back from the earlier dip and even showed a modest gain of 2% by day 90.

By this point, I had invested just over $130, and my total portfolio value stood at around $132. Not a huge return, but I considered it a win. More importantly, I had built a consistent investing habit, gained financial knowledge, and removed the psychological fear that had once kept me on the sidelines.

 

 

Key Takeaways from My 90-Day Micro Investing Journey

So, I tried micro investing for 90 days—here’s what I learned:

1. Small habits compound over time: Even investing a few dollars per week makes a difference when done consistently.
2. Automation is powerful: The round-up feature made saving and investing effortless.
3. Education matters: Understanding basic investment principles helped me make better decisions.
4. Emotion control is essential: Learning to ride out market fluctuations made me more resilient.

 

Is Micro Investing Worth It?

After completing the 90-day experiment, the most common question I get is: "Is micro investing really worth it?" My answer is a definite yes—with some important caveats. Micro investing won't make you rich overnight. It's not meant for rapid wealth accumulation or aggressive trading. But it is an excellent way to start building healthy financial habits, especially for beginners or those with limited disposable income.

Micro investing teaches you how the markets work, helps you build consistency, and removes the barrier of needing a large sum to get started. It’s also a great confidence-builder. Once you see how painless it is to invest a few dollars here and there, you start thinking more seriously about your financial future.

 

 

Micro Investing vs Traditional Investing

One of the things I learned while micro investing is how it differs from traditional investing. With traditional investing, you usually open a brokerage account, research individual stocks or mutual funds, and commit larger sums of money. It’s more hands-on, and often more stressful, especially for beginners.

Micro investing, on the other hand, lowers the stakes and automates much of the process. Platforms typically create diversified portfolios using ETFs and adjust allocations based on your risk profile. You don’t need to monitor your investments daily or worry about picking the "right stock." This hands-off approach was perfect for someone like me who was just getting started.

That said, I now feel more confident branching out into traditional investing thanks to what I learned during this 90-day journey.

 

 

Psychological Benefits of Micro Investing

One of the biggest unexpected outcomes from this challenge was the psychological shift I experienced. Before, I always saw investing as something “other people” did—people with money, experience, and insider knowledge. Micro investing shattered that illusion.

Investing became part of my identity, not just a financial task. I felt more in control of my money and more optimistic about my financial future. It was empowering to see my portfolio grow—even if just by a few dollars at a time—because it represented action and progress.

 

 

Common Myths About Micro Investing

Throughout the process, I encountered several myths about micro investing that are worth debunking:

• “You can’t make real money with micro investing.”
  True, the gains are small in the beginning. But as your income grows, you can increase your contributions. The point is not instant wealth, but long-term habit-building.
• “It’s not worth the effort.”
  In reality, there’s almost no effort involved after the initial setup. The automation features handle everything in the background.
• “Micro investing is risky.”
  All investing carries risk, but most platforms use diversified portfolios to help mitigate it. With small amounts, the emotional and financial risks are much lower.

 

 

Tips for Getting the Most Out of Micro Investing

Here are a few practical tips for those thinking about trying it out:

1. Choose the right platform – Not all apps are created equal. Compare fees, features, and investment options.
2. Start with automation – Set up round-ups and recurring contributions so the process is consistent.
3. Track your progress monthly – Don’t obsess over daily fluctuations. Look at trends over time.
4. Read up on the basics – Even a little financial literacy goes a long way.
5. Stay consistent – The real magic happens when you stick with it.

 

 

Final Thoughts: Micro Investing Is Just the Beginning

So, I tried micro investing for 90 days—here’s what I learned: it’s simple, accessible, and surprisingly impactful. No, I didn’t become a millionaire. But I took the first real step toward understanding and managing my finances. And that’s a far bigger win than any short-term profit.

Micro investing might not be the end goal, but it’s an incredibly useful starting point. Whether you're a college student with limited cash or someone trying to turn financial curiosity into financial action, it offers an easy entryway into the world of investing.

If you're sitting on the fence, I highly recommend giving it a try. You have very little to lose—and a lot of knowledge, confidence, and future growth to gain.
