Last updated August 2026
Short answer
Round-ups and small automated contributions into a diversified ETF portfolio, priced as a monthly subscription rather than a percentage. It costs Flat monthly subscription tiers (verify current), and on the question that decides most of the day-to-day experience, whether it works with the brokerage account you already have, the answer is: No (holds your money at Acorns).

Where it falls short: A flat monthly fee is enormous as a percentage of a small balance, which is exactly the balance the product is designed for. This review is published by Walnut, which competes with Acorns, and is written from public information rather than collected user ratings.
What Acorns is and how it works
Acorns rounds up card purchases to the nearest dollar and invests the difference, alongside optional recurring contributions, into a diversified ETF portfolio chosen by questionnaire. Pricing is a flat monthly fee by tier rather than a percentage of assets, which inverts the usual arithmetic.
In category terms it is hands-off automated investing (robo-advisors), and the AI component specifically automates small recurring investments. That phrase is worth reading literally: across this market, "AI" covers everything from a rebalancing rule to a conversational assistant, and the products are not interchangeable just because they share the label.
What Acorns does well
- It solves the real problem for many people, which is starting at all rather than choosing correctly
- Round-ups make contributions invisible, which is why they continue
- The flat fee becomes good value as the balance grows
These are real advantages, and if they describe what you want, Acorns is a reasonable choice regardless of what any competitor including us has to say about it.
Where Acorns falls short
A flat monthly fee is enormous as a percentage of a small balance, which is exactly the balance the product is designed for.
- On a small balance the monthly fee can exceed several percent a year, far above any percentage-based competitor
- It is aimed at accumulation rather than planning, so it does not answer questions about your wider finances
What Acorns costs
Flat monthly subscription tiers (verify current). Because it is not charged as a percentage of assets, the cost does not scale with your balance. That makes it proportionally cheaper as an account grows and relatively expensive on a small one, which is the opposite of how a robo-advisor fee behaves.
Fees change. The figure above is a guide rather than a quote, and the Acorns pricing breakdown goes into what else you pay on top. Confirm current pricing on Acorns's own site.
How Acorns compares with the alternatives
| Product | Cost | Connects your broker? | Best for |
|---|---|---|---|
| Acorns | Flat monthly subscription tiers (verify current) | No (holds your money at Acorns) | Starting to invest at all, when the barrier is behavioural |
| Betterment | ~0.25%/yr | No (holds your money) | Set-and-forget automated investing |
| Wealthfront | ~0.25%/yr | No (holds your money) | Hands-off investing with planning built in |
| SoFi | Free automated investing | No (holds your money) | Beginners in one money app |
| Schwab Intelligent Portfolios | No advisory fee; ETF expenses apply (verify current) | No (holds your money at Schwab) | Hands-off investing with no advisory fee, if you accept the cash allocation |
Within hands-off automated investing (robo-advisors), the products differ less on capability than the marketing suggests. Cost and whether your money has to move are the two variables that actually change your experience.
Where Walnut fits, and where it does not
To be upfront, since this is our site: the one factual difference worth knowing is that Acorns holds your money in its own account, while Walnut connects the brokerage you already have, read-only by default, and leaves your assets where they are. Walnut is free, with no paid plan and no fee on assets.
Where Walnut is the wrong choice: it will not manage money for you, it is not a registered investment adviser, it does no tax or estate planning, and it needs a brokerage account you already hold. If what you want is delegation rather than analysis, a robo-advisor or a human planner is the better answer and Acorns may well be it. The full self-assessment is on the Walnut review.

The trade-off to accept: A flat monthly fee is enormous as a percentage of a small balance, which is exactly the balance the product is designed for.
