Round-up investing apps

When it comes to putting your spare change on autopilot, the clear industry pioneer and standard for round-up investing is Acorns . However, depending on your broader financial goals and fee preferences, a few alternatives are worth considering.[cnbc.com](https://www.cnbc.com/select/best-micro-investing-apps/)

Here are the top contenders for investing spare change automatically:

• Acorns — Best for pure spare-change investing. It links to your debit or credit cards, rounds up your purchases to the nearest dollar, and automatically invests the difference into a diversified, expert-built portfolio of ETFs. It also offers retirement accounts (Acorns Later) and checking/savings options, though it operates on a monthly subscription fee model (starting around $3/month for basic tiers), which means small balances can see a high fee impact percentage-wise. You can check it out directly on the Acorns Website.[cnbc.com](https://www.cnbc.com/select/best-micro-investing-apps/)[[2](https://www.acorns.com/)](https://www.acorns.com/)
• Stash — Best for learning as you invest. Stash also offers automatic round-ups alongside fractional share investing, but it focuses heavily on micro-learning, guiding you on why you are buying specific stocks or funds rather than just putting everything strictly into a rigid robo-portfolio. Like Acorns, it runs on a monthly subscription fee.[cnbc.com](https://www.cnbc.com/select/best-micro-investing-apps/)
• Robinhood / Fidelity / SoFi — Best for commission-free recurring investments. While these traditional and zero-commission brokerages don't always do automated "card round-ups" in the traditional sense, they allow you to set up recurring automated transfers (e.g., $5 a week or $10 a paycheck) into fractional shares with $0 monthly subscription fees . For smaller amounts of spare change, avoiding a fixed monthly fee can keep more money working for you.[cnbc.com](https://money.usnews.com/investing/articles/investment-apps-for-beginners)[[2](https://www.acorns.com/)](https://www.fool.com/money/buying-stocks/best-investment-apps-for-beginners/)

If you'd like to narrow this down, tell me:

• Roughly how much spare change do you expect to invest per month?
• Are you looking strictly for a set-it-and-forget-it portfolio , or do you want to pick individual stocks?

I can help you calculate whether a subscription-based app or a free brokerage with recurring transfers makes more sense for your budget.

The gold standard and clear pioneer for this specific feature is Acorns.[investopedia.com](https://www.investopedia.com/best-stock-trading-apps-4587996)

Acorns

• How it works: It securely links to your credit or debit cards, automatically rounds up your everyday purchases to the nearest dollar, and sweeps that spare change into a diversified, automated portfolio of low-cost exchange-traded funds (ETFs).[investopedia.com](https://www.cnbc.com/select/best-investing-apps/)
• The Portfolio: Based on your age, goals, and risk tolerance, Acorns builds you a customized, modern portfolio using preset ETF allocations (ranging from conservative to aggressive) that handle rebalancing and dividend reinvestment for you.[investopedia.com](https://www.cnbc.com/select/best-investing-apps/)[[2](https://www.cnbc.com/select/best-investing-apps)](https://www.investopedia.com/best-stock-trading-apps-4587996)
• Pros: Completely hands-off; excellent user interface for beginners; includes recurring investment options and bonus investment multipliers.[investopedia.com](https://www.cnbc.com/select/best-investing-apps/)[[2](https://www.cnbc.com/select/best-investing-apps)](https://www.investopedia.com/best-stock-trading-apps-4587996)
• Cons/Watch Out: Acorns charges a flat monthly subscription fee rather than a percentage of assets under management. Because micro-investing starts with small amounts of spare change, a flat fee (typically starting at $3 to $5+ a month depending on the tier) can take a surprisingly large percentage bite out of a small balance if you aren't also adding larger recurring deposits.[investopedia.com](https://www.stash.com/learn/stash-vs-acorns)[[2](https://www.cnbc.com/select/best-investing-apps)](https://www.investopedia.com/best-stock-trading-apps-4587996)[[3](https://www.stash.com/learn/stash-vs-acorns)](https://www..com/learn/investing/-vs-/)

Alternatives to Consider

• Stash: Offers a similar round-up feature and automated "Smart Portfolios," but gives you more leeway to choose individual stocks and self-directed ETFs alongside the automated features. Like Acorns, it operates on a monthly subscription fee model.[investopedia.com](https://www.acorns.com/learn/investing/acorns-vs-stash/)[[2](https://www.cnbc.com/select/best-investing-apps)](https://www.stash.com/learn/stash-vs-acorns)
• Traditional Brokerages (Fidelity / Charles Schwab / Vanguard): While they don't feature a direct "spare change card round-up" tool, top brokerages allow you to set up recurring, automated fractional-share investments on a weekly or monthly basis for in subscription fees, giving you a purer, fee-free long-term ETF strategy if you prefer transferring fixed amounts instead of micro-transactions.

If you'd like, let me know:

• Approximately how much spare change you expect to generate per month (light vs. heavy card user)
• Whether you want strictly a hands-off robo-advisor or open access to individual stock/ETF picking

I can help you calculate whether the subscription fees make sense for your budget or if a flat recurring transfer is better.
