Of course! "Rounding up" your spare change to invest is a popular and easy way to get started. Here’s a comprehensive roundup of the best investing apps that offer this feature, along with key details to help you choose.
What is "Round-Up" Investing?
This feature automatically rounds up your everyday debit card purchases to the nearest dollar and invests the "spare change." For example, if you buy a coffee for $3.75, the app rounds up to $4.00 and invests the $0.25 difference.

Key Considerations Before You Choose
- Fees: The monthly fees on apps like Acorns and Stash can represent a significant percentage of your investment if your balance is low (e.g., a $3 fee on a $100 balance is a 3% annual fee). Make sure the value justifies the cost.
- Investment Control: Do you want a hands-off, managed portfolio (Acorns) or do you want to pick your own stocks (Stash, M1)?
- Your Primary Goal: Is your main goal just to invest spare change (Acorns), or is it to learn (Stash), or to manage your entire financial life (M1, Chime)?
- Account Minimums: Most of these apps have $0 minimums to start, making them very accessible.
Final Recommendation
- For the Absolute Beginner: Start with Acorns. It’s the simplest and most automated.
- For the Curious Beginner: Go with Stash. You'll get the automation of round-ups plus the education and choice to grow your knowledge.
- For the DIY Investor: Use M1 Finance. You get a powerful, free brokerage account with round-ups as a nice bonus feature.

Okay, let's break down "round-up investing apps." These apps, sometimes called "acorn apps" or "spare change apps," are designed to make investing easier and more accessible, especially for beginners. Here's a general overview and some popular examples:
How Round-Up Investing Works (The Basics):
- Linking Accounts: You connect the app to your checking account and/or credit cards.
- Tracking Purchases: The app monitors your transactions.
- Rounding Up: For each purchase, the app rounds the amount up to the next whole dollar. For example, if you buy a coffee for $2.50, the app "rounds up" to $3.00.
- Investing the Difference: The "spare change" (in the above example, $0.50) is accumulated. Once the accumulated amount reaches a certain threshold (usually $5 or $10), the app automatically transfers that money from your linked checking account to your investment account.
- Portfolio Selection: You typically choose a portfolio based on your risk tolerance and investment goals. The app then invests your money in a diversified portfolio of ETFs (Exchange Traded Funds) or sometimes individual stocks.
Key Advantages of Round-Up Investing Apps:
- Accessibility: Low minimum investments and the ability to invest small amounts make it easy to get started, even with limited funds.
- Automation: The automatic round-ups and investing make it a "set it and forget it" approach to saving and investing.
- Behavioral Change: It subtly encourages saving by turning everyday spending into investment opportunities.
- Diversification: They typically invest in ETFs, providing instant diversification across a range of assets.
- Educational: Some apps offer educational resources to help users learn more about investing.
Potential Drawbacks:
- Fees: Most round-up apps charge fees, either a flat monthly fee or a percentage of assets under management. It's crucial to understand the fee structure and whether it's worth it for your investment amount.
- Limited Investment Options: Investment choices are usually limited to pre-selected portfolios.
- Slow Growth (Initially): The initial investment amounts are small, so growth can be slow in the beginning.
- Potential for Overdrafts: If you don't have enough money in your checking account, the round-up transfers could trigger overdraft fees.

Important Notes:
- Investing Involves Risk: Remember that all investing involves risk, and you could lose money.

- Read the Fine Print: Carefully read the terms and conditions of any app before signing up.
To give you the best recommendation, tell me a little more about what you are looking for. For example:
- Are you a complete beginner, or do you have some investing experience?
- What is your risk tolerance (conservative, moderate, aggressive)?
