Acorns vs. Betterment (2026): Which Robo-Investing App Wins?

Acorns and Betterment are the two most popular robo-advisors in America, but they target different investors. Acorns automates investing through spare change round-ups and charges a flat monthly fee, making it perfect for people who want zero friction. Betterment charges a percentage fee and adds tax-loss harvesting and goal-based investing, making it ideal for larger portfolios. This guide breaks down the real differences so you can choose the right app.

Acorns vs. Betterment: Quick Verdict

Choose Acorns if you have a small balance and want the absolute simplest automation possible. Acorns rounds up every purchase and invests the spare change automatically. The $3/month flat fee is tiny if you have good round-up discipline. On balances under $12,000, Acorns is usually cheaper than Betterment.

Choose Betterment if you have a larger balance ($12,000+) or want sophisticated features like tax-loss harvesting and goal-based investing. Betterment's 0.25% annual fee is lower than Acorns' monthly charge when you scale up. CFP advisors are available on the premium 0.40% tier if you want expert guidance.

Acorns Review: Best for Automation-Obsessed Savers

Acorns was built on a single insight: most people don't invest because they forget to. The solution is brilliant — round up every purchase. Spend $3.75 on coffee, and 25 cents automatically gets invested. With 8 million+ users in the US, Acorns has proven this model works. You link a debit or credit card, pick a risk level, and Acorns does the rest. No decisions, no effort.

What Acorns does well

• Round-up investing — the core feature that makes saving effortless. Users invest an average of $166/month through round-ups alone.
• No minimum balance — start investing with literally any amount.
• Acorns Later IRA — included in most plans, letting you save for retirement alongside regular investing.
• Earn program — shop with 450+ brands and earn bonus automatic investments.
• Acorns Refer — earn cash by inviting friends.
• Simple fee — $3/month is predictable and easy to understand.

Acorns drawbacks

• No tax-loss harvesting — you miss automatic tax optimization.
• No goal-based investing — everything goes into the same portfolio.
• Expensive for large balances — on $50,000, $3/month = 0.072% annually, but you get no advisory features.
• Limited portfolio options — you pick Conservative-to-Aggressive; Betterment offers goal-specific portfolios.

Betterment Review: Best for Sophisticated Automation

Betterment is one of the original robo-advisors, founded in 2008. It's built for investors who want sophisticated, hands-off portfolio management with tax optimization. Rather than round-ups, you set a goal (retirement, down payment, vacation) and Betterment builds and manages a portfolio to reach it. Automatic tax-loss harvesting saves you money annually. For larger balances, it's the smarter choice.

What Betterment does well

• Tax-loss harvesting — automatically sells losing positions to offset gains and reduce your tax bill. Can save hundreds annually.
• Goal-based investing — create separate portfolios for retirement, down payment, college fund, etc. Each has its own time horizon and strategy.
• 0.25% advisory fee — low and transparent, scales with your balance.
• No account minimum — open an account with any amount.
• Premium tier (0.40%) — adds CFP financial advisor access and unlimited phone support.
• Socially responsible portfolios — ESG-focused investing options available.

Betterment drawbacks

• No round-up investing — you must set up automatic transfers or deposit manually.
• Less "set it and forget it" — requires more initial setup than Acorns.
• No built-in earning program — unlike Acorns' Earn feature with brands.

Fees Compared

Acorns charges $3/month for its Personal plan ($36/year). On a $5,000 balance, that's 0.72% annually. On a $10,000 balance, it's 0.36% annually. On a $50,000 balance, it's just 0.072% annually.

Betterment charges 0.25% annually on all balances. On a $5,000 balance, that's $12.50/year. On a $10,000 balance, $25/year. On a $50,000 balance, $125/year.

Betterment becomes cheaper than Acorns once your balance exceeds $12,000. For larger investors, Betterment's percentage fee is significantly cheaper.

Who Should Use Acorns?

• People who have trouble saving or investing consistently
• New investors starting with balances under $5,000
• Anyone who loves the idea of spare-change automation
• People who want the simplest possible interface and minimal decisions
• Investors who value IRA and regular investing in one app

Who Should Use Betterment?

• Investors with balances over $12,000 (where the fee math favors Betterment)
• Anyone interested in tax-loss harvesting and tax optimization
• Investors who want goal-based portfolios (retirement, down payment, education fund, etc.)
• People who prefer a web platform alongside the mobile app
• Investors willing to set up transfers but who want sophisticated automation handling the rest
