What Acorns does, and what it costs

Acorns is an app that rounds up your everyday purchases to the nearest dollar and invests the difference. If you buy coffee for $3.50, Acorns puts $0.50 into an investment account. The money goes into a portfolio of exchange-traded funds (ETFs) chosen based on answers you give about your risk tolerance.

Acorns charges a monthly subscription: $3 per month for the basic plan, $12 per month for the premium plan (which adds checking and savings features), or $68 per year if you pay annually. There are no trading fees or commissions on the investments themselves. If your account balance is small — under $1,000 — the monthly fee can eat up a meaningful share of your returns.

The app also offers a feature called "round-ups" on linked debit or credit cards, and you can add money manually if you want. Acorns does not pick individual stocks; it builds a diversified portfolio automatically based on your age and risk profile.

Key Takeaways

  • Acorns works best if you spend regularly with a card and want a low-friction way to start investing, because the round-ups happen automatically without you thinking about it.
  • The monthly fee ($3 to $12) is reasonable only if your account grows large enough that the fee becomes a small percentage of your balance — typically $5,000 or more.
  • Acorns invests in low-cost ETFs, which is a solid foundation, but you pay for convenience and automation rather than for better returns than you could get elsewhere.
  • If you already have a brokerage account or employer retirement plan, adding Acorns makes sense only if the round-up habit actually gets you to invest money you would not otherwise invest.
  • Acorns is not a substitute for a 401(k), IRA, or emergency savings account — it works alongside those, not instead of them.

When the monthly fee becomes worth paying

A $3 monthly fee on a $500 account costs you 7.2% per year in fees alone — before you earn or lose anything on the investments. That is expensive. On a $5,000 account, the same $3 per month is 0.72% per year, which is much more reasonable and in line with what you might pay for a low-cost mutual fund or robo-advisor.

The break-even point depends on how much you expect to earn on your investments. If your portfolio returns 7% per year and you pay $3 per month, you need roughly $5,000 to $7,000 in the account before the fee stops being the dominant cost. Below that, you are paying more in fees than you are earning in returns.

If you use the premium plan ($12 per month), you need a larger balance — typically $15,000 or more — for the fee to feel reasonable relative to your returns. The premium plan makes sense only if you use the checking and savings features it includes, not just the investing part.

How Acorns compares to other ways to invest small amounts

If you want to invest round-ups or small amounts regularly, you have other options. A traditional brokerage account (Fidelity, Vanguard, Charles Schwab) lets you invest any amount with no monthly fee, though you have to remember to transfer money yourself. A robo-advisor like Betterment or Wealthfront charges a percentage of your assets (usually 0.25% per year) rather than a flat monthly fee, which can be cheaper if your balance is small.

A 401(k) or IRA through your employer or bank is almost always the better first step if you have not started one yet, because contributions reduce your taxable income and many employers match contributions. Acorns does not offer either of those tax advantages.

The real advantage Acorns has is the round-up automation. If that feature genuinely changes your behavior — if you invest money through Acorns that you would otherwise spend — then the fee is worth it. If you would invest the same amount anyway through a cheaper account, Acorns costs you money for no benefit.

What happens to your money inside Acorns

Acorns builds a portfolio of ETFs for you based on your age and how much risk you say you can tolerate. A younger investor might get a portfolio that is 90% stocks and 10% bonds; an older investor might get 50% stocks and 50% bonds. The portfolios are diversified across US stocks, international stocks, and bonds.

Acorns rebalances your portfolio automatically — meaning it sells some of what has grown and buys more of what has fallen, to keep your mix at the target. This is a sound investing practice and saves you the work of doing it yourself.

Your money is held by a custodian (usually Apex Clearing or a similar firm) and is separate from Acorns' own money. If Acorns goes out of business, your investments are protected. You can withdraw your money at any time with no penalty, though you may owe taxes on gains if you withdraw from a taxable account.

Tax considerations and account types

Acorns offers both taxable accounts and IRAs. A taxable account has no contribution limits and no tax advantages, but you pay capital gains tax on profits when you sell. An IRA (Individual Retirement Account) lets you contribute up to $7,000 per year (as of 2024, and the limit changes over time) and offers tax advantages — either deductions now (traditional IRA) or tax-free growth (Roth IRA).

If you are using Acorns as a taxable account, the round-ups and automatic rebalancing can trigger small capital gains each year, which you will owe tax on. This is not unique to Acorns — any investment account works this way — but it is worth knowing. An IRA avoids this problem because gains inside an IRA are not taxed until you withdraw.

For most people, maxing out a 401(k) or IRA first makes more sense than using Acorns, because the tax advantages are much larger than the fee savings from a cheaper brokerage.

Red flags and limitations

Acorns is not a substitute for an emergency fund. You should have three to six months of expenses in a savings account before you start investing. Acorns invests your money in the stock market, which goes up and down; if you need the money in the next few years, you might have to sell at a loss.

The round-up feature works only if you use a linked debit or credit card. If you pay with cash or check, nothing gets invested. Some people find the round-ups too small to feel meaningful; others find them motivating. It depends on how much you spend and how often you use a card.

Acorns does not offer financial advice tailored to your situation. The portfolio it builds is based on your age and risk tolerance, but it does not know your income, debt, or other financial goals. If you need help with a broader financial plan, you need a financial advisor, not an app.

When Acorns makes sense

Acorns works well if you spend regularly with a debit or credit card, have at least $5,000 to invest (so the fee is not too large), and want a simple way to invest without thinking about it. It is also useful if you are new to investing and the round-up feature makes the idea of investing feel less intimidating.

Acorns also makes sense if you already have a 401(k) or IRA and have money left over that you want to invest. In that case, Acorns is a supplement to your main retirement savings, not a replacement.

If you have a small balance (under $2,000), a strong emergency fund, and you are not yet using a 401(k) or IRA, you are probably better off opening an IRA first and investing through a low-cost brokerage with no monthly fee.

Frequently Asked Questions

Can I lose money in Acorns?

Yes. Acorns invests in the stock market, which fluctuates. Your account value can go down if the market falls. Over long periods (10+ years), stock market returns have historically been positive, but there is no may provide. If you need the money soon, the market timing matters.

Does Acorns report to the IRS?

Yes. If you earn more than $10 in gains or dividends in a taxable account, Acorns sends a 1099 form to the IRS and to you. You report this on your tax return. IRA accounts do not trigger this reporting until you withdraw money in retirement.

What if I stop using Acorns?

You can close your account and withdraw your money at any time. There is no penalty. If you have gains in a taxable account, you will owe capital gains tax on them when you sell. An IRA has withdrawal rules depending on whether it is traditional or Roth.

Is Acorns safer than keeping money in a savings account?

Acorns is not safer in the short term — the stock market is more volatile than a savings account. Over decades, stocks have historically returned more than savings accounts, but that comes with risk. A savings account is insured by the FDIC up to $250,000; Acorns investments are not insured against market losses.

Can I use Acorns instead of a 401(k)?

No. A 401(k) offers tax deductions and often employer matching, which Acorns does not. If your employer offers a 401(k), contribute to it first, especially if they match. Acorns can be a second step after you have maxed out retirement accounts.
