Introduction: The Rise of Micro-Investing
According to a 2023 Bankrate survey, nearly 40% of Americans use some form of micro-investing to build wealth, with apps like Acorns leading the pack. Micro-investing platforms allow users to invest small amounts of money automatically, often by “rounding up” everyday purchases to the nearest dollar and investing the difference.
This step-by-step guide explores how Acorns’ round-up investing feature performs after three years of consistent use. We will walk through how to set it up, track returns, and optimize your strategy to make the most of your spare change investments.
Key Takeaways: After 3 years, Acorns round-up investing can yield steady returns depending on portfolio choice and market conditions. Understanding fees, portfolio types, and reinvestment timing is crucial to maximizing growth.
Prerequisites Before You Start
- Basic understanding of investment accounts and risk tolerance
- Active checking account linked to your Acorns app
- Smartphone with the Acorns app installed and verified
- Monthly budget that supports small, consistent round-ups without causing overdraft
Here’s where most people get it wrong.
Step 1: Create and Link Your Acorns Account
Download the Acorns app and sign up by entering your personal information. Link your primary spending account (checking or debit card) to enable round-ups on purchases.
Pro tip: Use a checking account with no overdraft fees to avoid unexpected charges from round-ups.

Step 2: Enable Round-Up Investing
In the app settings, activate the round-up feature. Each purchase you make will be rounded up to the nearest dollar, and the difference will be transferred to your Acorns investment account.
Pro tip: Opt for round-ups on debit and credit cards to maximize the frequency of small investments.
But here’s the catch.
Step 3: Choose Your Portfolio Based on Risk Tolerance
Acorns offers several portfolios ranging from conservative to aggressive, composed of ETFs across stocks and bonds. Your choice impacts potential returns and volatility.
Pro tip: Review historical annualized returns by portfolio type on Acorns’ website—aggressive portfolios averaged around 8-10% annual returns over the past 5 years (source: Acorns disclosures).
Here’s where most people get it wrong.
Step 4: Monitor Your Round-Up Contributions
Check your app weekly or monthly to see how much your round-ups have accumulated. Average users invest about $30-$50 monthly through round-ups alone (NerdWallet, 2023).
Pro tip: Increase your round-up amount by enabling “Recurring Investments” if you want to accelerate growth.

Step 5: Track Your Returns Over Time
Acorns provides a summary of portfolio growth including dividends and appreciation. After 3 years, an initial $30/month round-up investment with moderate portfolio risk could grow to approximately $1,200–$1,400, depending on market conditions.
Pro tip: Use the app’s detailed performance charts to identify periods of higher growth and adjust your portfolio if needed.
Step 6: Understand Fees and Their Impact
Acorns charges $3/month for the Personal plan, which includes round-up investing and a retirement account option. Over 3 years, this totals $108, which can reduce net returns, especially for small balances.
Pro tip: Consider your average balance to ensure fees don’t outweigh gains. For balances under $1,000, fees can significantly impact net returns.
Step 7: Reinvest Dividends Automatically
Acorns automatically reinvests dividends earned from ETFs, compounding growth over time. This feature accelerates your portfolio’s growth beyond just the round-up amounts.
Pro tip: Dividend reinvestment is crucial for maximizing long-term returns, so keep this feature enabled.

Step 8: Withdraw or Rebalance When Needed
After 3 years, you may want to rebalance your portfolio or withdraw funds. Acorns allows easy withdrawals, but note it can take 3-5 business days for funds to transfer.
Pro tip: Avoid frequent withdrawals to benefit from compounding. If your risk tolerance changes, update your portfolio allocation in the app.
Step 9: Use Acorns Later for Retirement Savings
Acorns Later is a retirement account linked to your main investing account. After establishing round-up investments, consider scaling up retirement contributions via Acorns Later for tax advantages.
Pro tip: Automate monthly contributions to Acorns Later to build a diversified retirement portfolio alongside your round-up investing.
Step 10: Review and Adjust Annually
Market conditions and personal finances change, so review your investment strategy yearly. Adjust your round-up settings, portfolio risk level, or monthly recurring contributions accordingly.
Pro tip: Use annual statements from Acorns to analyze fees paid versus returns earned for smarter investing decisions.
Okay, this one might surprise you.
