Acorns Review

Your Details Done
by Updated

Acorns is a robo-advisor whose service is based on the old idea of saving your spare change. Indeed, its name comes from the proverb, paraphrased here, that mighty oaks start as small acorns. This robo-advisor rounds up all of your credit or debit card purchases to the nearest dollar and then invests that change into a portfolio of exchange-traded funds (ETFs). Everything is done online and everything is automated, so you can just set it and forget it. The service specifically targets college students and young adults who have a difficult time saving money or who are new to investing. Should you consider using it to invest your money?

Best for

  • College students with little or no regular income
  • People who are new to investing


  • Relatively high fees for low balances (less than $5,000)
  • Little transparency about investment options

Pricing: How Much Does Acorns Cost?

Unlike most robo-advisors, who charge a fee based on your account balance, Acorns charges a flat monthly management fee. Since its target customer is someone in college or just starting out, the cheapest plan, Acorns Core, costs $1 per month. This plan is a basic taxable investing account. It comes with a cash-back-for-your-portfolio feature for spending money with Acorns’ partners, called Found Money®.

If you want to add a Roth or traditional individual retirement account (IRA), you will need to pay $2 per month for the Acorns Later plan. For a checking account on top of that, you'll pay $3 per month. This most expensive plan, called Acorns Spend, comes with a Visa debit card that links to Acorns’ automatic investing services.

College students with a valid .edu email address will not be charged a management fee for the Acorns Core plan. This offer lasts up to four years from the time of opening an account. The other account options do not offer a reduced fee with a .edu email.

If you have $1 million or more to invest, the company may offer a different management fee. Acorns specifically recommends reaching out if you have that much.

How Acorns Works

You can open an account by going either to the website or mobile app, which, by the way, has won multiple awards for its attractive design. You will need to enter some personal information, link a bank account to Acorns, set up your financial goals and indicate your risk tolerance.

Based on your personal information, Acorns will put you in one of five prebuilt portfolios: conservative, moderately conservative, moderate, moderately aggressive or aggressive. Generally speaking, the higher your risk tolerance and longer your time horizon, the more you will be invested in higher-risk assets with higher growth potential. There is no minimum for opening an account but you will need at least $5 before you can start investing.

Acorns asset allocation for moderate portfolios

Accounts are funded through what Acorns calls roundups. You can start making roundups by linking credit and debit cards to your Acorns account. What are roundups? When you make a purchase with an Acorns-linked card, the company will round the purchase up to the nearest dollar, withdraw that difference from your bank account and invest it into your portfolio. If you spend $5.60 with your card, it will round that up to $6.00 and invest the difference of $0.40 into your portfolio. It’s a little at a time, but the idea is that the change will add up.

You can link an unlimited number of credit and debit cards to your account. Acorns also offers a branded checking account and debit card through a partnership with Lincoln Savings Bank. This account and card are set up to work seamlessly with your Acorns account. With the checking account you can check your roundups and investments in real time. The checking account and debit card are only available if you choose the Acorns Spend option.

Acorns will invest roundups automatically but you can also choose to manually invest. Manually investing would require you to go through a list of your purchases and decide which you want to round up and invest. 

In addition to funding the account through your roundups, you can also manually transfer lump sums into your Acorns account from a bank account. 

Key Features

The target market for Acorns is young adults who are new to investing. One way the company tailors accounts to this clientele: it doesn't charge them a management fee for four years if they have a valid .edu email address. That's a savings of $48 ($12 x 4), which admittedly doesn't sound like a lot. But if you're in college and not even thinking about saving or investing, it's a great head start. 

Acorns’ most distinguishing feature is roundups. And while a roundup doesn’t necessarily add a lot per transaction, all that change adds up over time.

Acorns Investment

Found Money® is a cash-back rewards program that adds bonus cash to your portfolio when you spend money with one of Acorns’ partners. Bonus amounts range from 1% to 5%. There are currently two kinds of Found Money® transactions. For “Tap and Get” offers you have to go through the Acorns app and then make a purchase through your mobile phone. For “Simply Spend” offers you just need to use your Acorns-linked card to make purchases with partner brands.

Note that, unlike a cash-back credit card that offers cash back on all purchases, Found Money® offers only exist for companies that partner with Acorns. There are currently more than 250 partners, including Boxed, Expedia, Lyft, Nike and Sephora.

Acorns also provides educational content through its website and app. This content explains important investment terms and concepts using simple language. You can also find useful financial advice to help you make the most of your savings and investments.

Acorns' Investing Strategy

How is your money actually invested? Like most robo-advisors, the company uses an investment philosophy called modern portfolio theory. The whole idea of modern portfolio theory is investing in a diversified portfolio, across multiple asset classes, in order to lower risk while maximizing return. The father of modern portfolio theory, Harry Markowitz, is an advisor for Acorns. How’s that for bragging rights?

Acorns uses ETFs from seven asset classes: corporate and government bonds, domestic and international large company stocks, small company stocks, emerging markets and real estate. How much you're invested in each (or your asset allocation) depends on your risk tolerance level and your investing goals.

The company offers fewer ETF options than other robo-advisors. Some, like Wealthfront and Betterment, also provide more detailed explanations of their investing strategies. Acorns operates more on the principle of “let us worry about the technical details.” While some might want more transparency, this approach makes things easier for Acorns’ target market of young people who are new to investing.

Who Acorns Is For

Acorns is geared toward young and new investors. College students particularly benefit and might qualify for no-fee management for up to four years. If you are just starting to invest, an Acorns account is a great way to get started.

Or if you just find it difficult to save, you may find Acorns' roundups helpful. This service automates everything so there’s no fear of forgetting to transfer money. It's also an affordable option if you don’t have much to put toward investing.

Acorns Homepage

Acorns' services are completely digital, which is fine for someone who doesn’t want or need to meet with a real person to talk about their investments. If you are a serious investor who wants to invest in more than the seven ETFs or in other types of funds, you should look elsewhere. Other robo-advisors also offer more account types, such as 529 college savings plans.

If you have more $25,000 in investable assets, you may want to consider getting a human advisor instead. You can use SmartAsset's financial advisor matching tool to get linked with an advisor who suits your needs.

Available Features

  • Automatic rebalancing
  • Fractional shares

Unavailable Features

  • Direct indexing
  • Human advisors

What’s the Catch?

The biggest catch with an Acorns account is the cost. Unlike other robo-advisors, Acorns charges a flat management fee. Spending just $1 each month sounds great, right? Well it can actually work out to a high percentage of your assets if you don’t have a lot of money in your account (and most of Acorns’ users likely don’t have very much in their accounts).

Imagine that you have $500 in your account. A $1 fee would equal 0.2% of your assets under management (AUM). That’s 0.2% each month; if you have $500 in your account for an entire year, you would end up paying an annual fee of worth 2.4% of your AUM. That’s a very high rate compared to other robo-advisors, which typically charge an annual rate of 0.50%, or less, of AUM. If you opt for one of Acorns’ more expensive plans, you will pay even more.

On the flip side, the flat monthly fee also translates to a relatively low fee, percentage-wise, if you have more in your account. With Acorns Core ($1/month), an account balance of $5,000 would bring your annual fee down to about 0.24%, which is similar to the management fee from other big robo-advisors. You would need about $10,000 with an Acorns Later (retirement) account to get down to a fee of 0.25%. Once your account is that large, the monthly fees from Acorns start to look like a good deal.

With that said, you should be aware that the ETFs that Acorns invests your money in will charge their own fees. Acorns says it bakes these fees into the prices of the ETF shares.

Fees aside, it’s worth noting that other advisors also offer more robust investing services which can be useful as the value of your investments increases. For example, other robo-advisors help reduce your tax burden with tax-loss harvesting, This is a feature that sells investment that have lost value and then buys very similar investments, allowing you to claim a capital loss deduction on your taxes while staying invested in the market. The end result is that you decrease the amount you owe in taxes at the end of the year. While many Acorns customers don’t earn enough income for tax-loss harvesting to make a significant difference, the taxes could still add up.

Acorns recently began offering retirement accounts, which are great if you need to build retirement savings. However, the company still isn’t the most comprehensive robo-advisor and other services may better cover all of your savings goals.

You also don’t get any face-to-face professional advice from robo-advisors like Acorns. Some people prefer being able to ask questions face-to-face, particularly if their financial situation is more complex. No matter your personal situation, talking with a financial advisor who is a real person can help you to create a more comprehensive plan. It will also allow you to combine your retirement planning with other financial and tax considerations, so that you have one financial plan to cover your entire life.

For some people, another “catch” is that the company will have data on every purchase that you make with your cards. You could choose not to link any cards to your account and add money to your account only by making deposits, but then you wouldn’t be taking advantage of what makes Acorns unique.

Competition: How Does Acorns Stack Up?

This robo-advisor is designed for young investors and college students with little or no regular income. Like other robo-advisors, Acorns offers multiple types of accounts that can help you to start investing, whether through a taxable or retirement account. It doesn’t offer as many features or account types as some other services, so it isn’t necessarily the best option for users of every life stage.

Stash is one company that operates in a similar market. It’s tailored to people who are new to investing and it includes a lot of informational materials about saving money and investing. Stash is nearly identical to Acorns in price, but it isn’t actually a robo-advisor. It doesn’t manage accounts directly and only helps to guide users through the investing process. 

Acorns offers the same basic accounts as other robo-advisors, but its offerings aren’t the most comprehensive. Most robo-advisors, including Wealthfront, Betterment and Personal Capital, offer various types of accounts.

A serious investor will also find that Acorns doesn’t offer all the tools and features that many of its competitors do. For example, Wealthfront and Betterment both offer tax-loss harvesting. Wealthfront also offers direct indexing, a similar strategy for taking advantage of capital losses to lower your tax bill. This feature is only available for accounts with at least $100,000, but it is very useful if you have that much to invest.

Beyond taxes, Acorns may not regularly rebalance your portfolio. Some robo-advisors do this daily or monthly to ensure your investments stay on track. Other robo-advisors also offer more personalized portfolios and more asset classes.

Still, if you’re a young investor with a low net worth, you’d probably see limited benefit from features like tax loss harvesting and rebalancing.

Acorns does have a clear advantage on account minimums. Most robo-advisors require at least $500 to get started, while Acorns requires only $5 to start investing. This makes it an affordable option if money is tight. With that said, it’s not alone in having low account minimums. Betterment, for instance, has no minimum.

As for management fees, Acorns charges a flat monthly fee of between $1 and $3. With a low balance, this works out to an annual rate of more than 0.5% of your AUM. You can easily find another service charging a fee of 0.5% or less.

Acorns is completely Internet-based and investors who feel more comfortable talking with human financial advisors might prefer another company. Betterment has a plan that allows you to talk with a financial expert over the phone, though it requires a minimum balance of $100,000.

Robo-Advisor Management Fee  Minimum Balance  Best For
Flat monthly fee between $1 and $3 $0 to open, $5 to start investing
  • College students with little or no regular income
  0.25%   $500
  • Investors with smaller sums to invest
  • Investors who don’t need a human advisor
  0.25% - 0.40%  $0 
  • First-time investors with low savings balances
  • Goal-based investors

Bottom Line: Should You Use Acorns?

Acorns is designed for a specific customer: a person who has a difficult time saving money or doesn’t know a lot about investing. As such, young people are the clear target market, and college students with little or no income will particularly benefit. 

The company’s roundup system probably won’t earn you a ton of money, but it’s certainly a good place to start, and a little bit saved during your college years can really grow over the next few decades. And because it automates everything, you don’t have to worry about transferring money. On the flip side, the company doesn’t offer many investing tools, like regular portfolio rebalancing and tax-loss harvesting. It also offers only a few account types. These account options may be enough to cover novice investors, but it also means that you will eventually need to get an account with another company if your needs or goals change.

Tips for Finding an Advisor

  • Acorns does not provide many features for investors who have a more complex financial situation. If you have multiple types of investments, you may want to talk to a financial advisor. Financial advisors are professionals who can help you to figure out everything from planning your investments to navigating tax season.
  • The rise of robo-advisors has coincided with a bull market. But what do the algorithm-driven advisors do when there's a major downturn? The general wisdom is not to panic when things head south, but an automated system of rebalancing may sell when prices are low. Before you sign up with any advisor - robo or human - make sure you know and like what they will do should stock prices fall.
