Acorns and Stash are two of the most popular micro-investing apps aimed at beginners, but they take meaningfully different approaches to building your portfolio. Acorns automates everything with round-ups and managed portfolios, while Stash gives you more control to pick individual stocks and ETFs alongside guided recommendations. In 2026, both platforms have expanded beyond investing into banking and education. Here is a detailed comparison to help you choose.
Investment Approach
Acorns is fully automated. You choose a risk level from conservative to aggressive, and Acorns builds and manages a diversified ETF portfolio for you. You cannot select individual stocks or customize your allocation beyond choosing a portfolio tier. Round-ups from linked cards automatically invest your spare change, and recurring investments keep money flowing in consistently. Stash takes a hybrid approach. It offers curated thematic investments organized into categories like Clean and Green, American Innovators, and Delicious Dividends, making it easy to invest in themes you care about. But you can also browse and buy individual stocks and ETFs on your own. Stash provides guidance without removing your ability to choose.
Account Types
Both platforms offer taxable investment accounts and retirement accounts including Traditional and Roth IRAs. Acorns also offers custodial investment accounts for children through Acorns Early, while Stash offers a custodial account called Stash Kids. Both platforms include a banking component with a debit card and direct deposit capability. Acorns’ banking features include real-time round-ups and Found Money partnerships, while Stash offers Stock-Back rewards that give you fractional shares of stock instead of traditional cash back when you use your Stash debit card.
Stock-Back vs Round-Ups
This is one of the most interesting differences. Acorns’ round-ups take the spare change from your purchases and invest it automatically. Buy a coffee for $4.25 and $0.75 goes into your portfolio. Stash’s Stock-Back gives you fractional shares of the companies where you shop. Buy something at Walmart and receive a small fraction of Walmart stock. Buy from Amazon and get Amazon stock. It is a creative way to build positions in companies you already support. The psychological appeal of owning stock in companies you shop at can be motivating for new investors.
Pricing Comparison
Both platforms use tiered monthly subscription pricing. Acorns starts at one dollar per month for basic investing and goes up to five dollars for the family plan with kids accounts. Stash starts at three dollars per month for basic investing and banking and goes up to nine dollars for the plan that includes custodial accounts and premium research. At the lower tiers, Acorns is cheaper, but the difference becomes less significant as balances grow. Both platforms’ flat fees represent a high percentage cost for very small balances and become more reasonable as portfolios grow past a few thousand dollars.
Education and Learning
Both apps invest heavily in financial education, but Stash’s educational content is more integrated into the investing experience. Stash Learn provides articles, guides, and market news directly alongside investment options, helping you understand what you are buying and why. Acorns provides educational content through its Money Matters newsletter and in-app resources, but the automated nature of the platform means you can invest without ever engaging with the educational content. If learning about investing is a priority, Stash does a better job of teaching you while you invest.
Portfolio Performance
Acorns’ managed portfolios use broadly diversified ETFs from providers like Vanguard and BlackRock, delivering market-rate returns appropriate to each risk level. Since Stash lets you pick individual stocks and thematic ETFs, your returns depend entirely on your choices. This means Stash has both higher upside potential and higher risk. A well-chosen Stash portfolio could outperform Acorns, but a poorly chosen one could significantly underperform. For most beginners, Acorns’ automated diversification reduces the risk of costly mistakes.
Who Should Choose Acorns?
Choose Acorns if you want a completely hands-off experience. You do not want to research stocks, pick investments, or make trading decisions. You just want your money to grow automatically through spare change round-ups and recurring investments. Acorns is also better if you want the simplest possible pricing with a lower entry-level cost.
Who Should Choose Stash?
Choose Stash if you want to learn about investing while you do it. You want the ability to pick individual stocks and thematic ETFs, but you also want guidance and guardrails to prevent major mistakes. The Stock-Back feature appeals to you, and you like the idea of building positions in companies you already shop with. Stash gives you more agency without overwhelming you with a full brokerage platform.
The Bottom Line
Both Acorns and Stash succeed at their core mission of making investing accessible to beginners. The choice comes down to how involved you want to be. Acorns is the better set-it-and-forget-it option, while Stash is better for curious beginners who want to learn and make their own choices. Either way, the most important thing is that you start investing, and both platforms make that remarkably easy.
