Acorns is an investment app, not a savings account
Acorns is a mobile app that invests your money in a portfolio of exchange-traded funds (ETFs), not a place to keep cash safe and liquid like a savings account. When you link your debit card or bank account to Acorns, the app rounds up your purchases to the nearest dollar and invests the difference. A $3.50 coffee purchase becomes a $4 charge, and Acorns puts the 50 cents into your investment account. Over time, these small amounts accumulate and grow through market returns — or decline, depending on market conditions.
A savings account at a bank holds your money in cash, earns a fixed interest rate set by the bank, and is insured by the FDIC up to $250,000. Your balance never goes down unless you withdraw it. An Acorns account holds investments that fluctuate daily with the stock market. You can lose money. There is no FDIC protection. The money is not immediately available — you can withdraw it, but it takes a few business days and you may owe taxes on gains.
If you need money to stay safe and available for emergencies or near-term expenses, a savings account is the right tool. If you are comfortable with market risk and do not need the money for years, Acorns is a way to invest small amounts without thinking about it.
Key Takeaways
- Acorns invests your money in ETFs and is not protected by FDIC insurance the way a bank savings account is.
- Your Acorns balance changes daily based on stock market performance and can go down as well as up.
- Withdrawals from Acorns take several business days and may trigger capital gains taxes, unlike a savings account withdrawal.
- Acorns charges a monthly subscription fee ($1 to $5 depending on the plan), while most savings accounts do not.
- A savings account is for money you need to keep safe and accessible; Acorns is for money you can leave invested for years.
How Acorns invests your money
When you open an Acorns account, you answer questions about your age, income, and how comfortable you are with risk. Acorns then assigns you a portfolio — usually a mix of U.S. stock funds, international stock funds, and bond funds. The exact mix depends on your risk profile. A conservative portfolio might be 30 percent stocks and 70 percent bonds. An aggressive one might be 90 percent stocks and 10 percent bonds.
Every time you make a purchase with a linked card, Acorns rounds up and invests the difference. You can also add money manually. Acorns holds all your money in a single brokerage account and rebalances it periodically to keep the mix of funds aligned with your chosen portfolio. You see the total value of your account, which includes both the money you put in and any gains or losses from market movement.
Acorns also offers a feature called "Found Money" that gives you cash back from certain retailers and invests it automatically. This is separate from the round-up feature and depends on which stores participate in the program.
Fees and costs that savings accounts do not have
Acorns charges a monthly subscription: $1 per month for the basic plan, $3 per month for the mid-tier plan, or $5 per month for the premium plan. A savings account at most banks charges nothing. Over a year, even the cheapest Acorns plan costs $12, which is money that does not go into investments.
Acorns also charges internal fund fees called expense ratios. These are built into the ETFs themselves and typically range from 0.05 percent to 0.20 percent per year. A savings account has no internal fees — you earn interest on the full balance.
When you withdraw money from Acorns, you may owe capital gains tax on any profit you made. If you invested $500 and it grew to $600, you owe tax on the $100 gain. A savings account withdrawal has no tax consequence — interest earned is taxed, but the withdrawal itself is not.
When Acorns makes sense versus a savings account
Acorns works best if you have money you will not need for at least three to five years. The stock market fluctuates in the short term but tends to grow over longer periods. If you invest $50 per month for five years and the market returns 7 percent annually on average, you could have around $3,300 instead of $3,000. But if you need that money in six months and the market has dropped, you could have less than you put in.
A savings account works best for money you need within the next year or two, or for an emergency fund. The interest rate is lower — currently around 4 to 5 percent at high-yield savings accounts — but your balance never shrinks and you can withdraw it the same day or next business day.
Many people use both. They keep three to six months of expenses in a high-yield savings account for emergencies, and invest longer-term money in Acorns or other investment accounts. This way, they are not forced to sell investments at a loss if something unexpected happens.
How to withdraw money from Acorns
To withdraw from Acorns, open the app, go to your account settings, and request a withdrawal. Acorns transfers the money back to your linked bank account. The transfer usually takes three to five business days. You cannot withdraw just part of your investment — you withdraw the full account value or nothing.
When you withdraw, Acorns closes your account. If you want to invest again later, you have to open a new account. This is different from a savings account, where you can withdraw and deposit as often as you want without closing anything.
Before you withdraw, check whether you have unrealized gains. If you invested $1,000 and your account is now worth $1,200, you will owe capital gains tax on the $200 profit when you file your taxes. Acorns does not withhold this tax automatically — you have to pay it yourself when you file.
FDIC insurance and account safety
Acorns holds your money at a brokerage firm, not a bank. Brokerage accounts are protected by SIPC (Securities Investor Protection Corporation), not FDIC insurance. SIPC covers up to $500,000 per account if the brokerage fails, but it does not protect you if your investments lose value. If the stock market drops 20 percent, your account drops 20 percent — that is not a loss covered by SIPC.
A savings account at a bank is FDIC-insured up to $250,000. If the bank fails, the government guarantees your money. If the stock market drops, your savings account balance does not change. This is the core difference in safety between the two products.
Acorns itself is a legitimate company regulated by the SEC and FINRA, but that does not mean your money is risk-free. It means the company is operating legally and your account information is secure. Your investment risk is market risk, not company risk.
Frequently Asked Questions
Can I use Acorns as my emergency fund?
No. Emergency funds need to be in a savings account or money market account where the balance never goes down and you can access the money within one business day. Acorns takes three to five days to withdraw and your balance can drop 10 or 20 percent in a market downturn. Keep emergency money separate in a high-yield savings account.
Does Acorns pay interest like a savings account?
No. Acorns does not pay interest. Your money grows through investment returns, which means it can also shrink. A savings account pays a may provide interest rate set by the bank. The interest is lower but certain.
What happens to my Acorns account if the company shuts down?
Your investments are held at a brokerage firm separate from Acorns, so your money is protected even if Acorns closes. You would be able to transfer your account to another brokerage or withdraw it. This is different from a bank failure, where FDIC insurance protects your deposits.
Can I set up automatic transfers to Acorns like I do with a savings account?
Acorns does not offer automatic transfers from your bank account. You can only add money manually or through round-ups on purchases. A savings account lets you set up automatic deposits on a schedule, which makes it easier to build an emergency fund consistently.
Is Acorns better than a savings account for saving money?
It depends on your timeline. For money you need within two years, a savings account is better — it is safer and more accessible. For money you will not touch for five years or more, Acorns may grow your money faster because of stock market returns. Most people benefit from using both for different goals.
