Acorns is worth it for complete beginners who need the friction of round-up investing to start saving. The $3/month fee is reasonable for small accounts but becomes expensive as a percentage as your balance grows — on a $500 portfolio, $3/month equals 7.2% annually. Once your balance exceeds $14,400, Betterment (0.25%) becomes cheaper in absolute dollar terms.

How much does Acorns cost?

Acorns charges $3/month for its standard plan, which includes a personal investment account, IRA, and checking account. There is no free tier. At $36/year flat, Acorns is more expensive than Betterment for portfolios above $14,400 and significantly more expensive on a percentage basis for small portfolios.

What is Acorns Round-Ups?

Acorns Round-Ups automatically round your everyday purchases up to the nearest dollar and invest the difference. For example, a $4.30 coffee purchase rounds up to $5.00, and $0.70 is invested. Round-Ups are transferred to your Acorns account when they accumulate to $5. This is Acorns' signature feature — designed to make saving feel effortless.

Does Acorns offer IRA accounts?

Yes. The $3/month Acorns plan includes a Roth IRA, Traditional IRA, or SEP-IRA account. Acorns automatically selects an IRA type based on your answers during setup (though you can override this). The same portfolio ETFs are used across all account types.

Is Acorns better than Betterment?

Acorns is better for complete beginners who need round-up automation to start saving — the behavioral nudge is genuinely valuable. Betterment is better for anyone with $14,400+ who would benefit from tax-loss harvesting and pays less in absolute dollar terms above that threshold. Betterment also has more robust goal planning tools.

Acorns Review 2026 — Fees, Features, and Who the Micro-Investing App Is Best For

Acorns charges $3/month flat, invests your spare change through round-up purchases, and has managed over $6 billion for more than 10 million accounts. It is designed specifically for beginners who have never invested before — the round-up mechanism and simplicity lower the psychological barrier to starting. The trade-off: at $3/month (=$36/year), Acorns becomes more expensive than Betterment above $14,400 and far more expensive than Fidelity Go or M1 Finance. It is a starter platform, not a long-term destination for growing portfolios.

Acorns Fees: The Math on $3/Month

Acorns charges a flat $3/month = $36/year. This sounds cheap — until you look at it as a percentage of assets:

Portfolio Size	Annual Fee ($36)	As % of Portfolio
$500	$36	7.2%
$1,000	$36	3.6%
$5,000	$36	0.72%
$10,000	$36	0.36%
$14,400	$36	0.25% (= Betterment)
$25,000	$36	0.14%
$50,000	$36	0.07%

The break-even vs Betterment: At $14,400, both cost $36/year. Below $14,400, Acorns is cheaper in absolute dollars but Betterment is cheaper as a percentage. Above $14,400, Betterment is cheaper in absolute dollars.

The real cost for beginners: Most Acorns users start with $0–$1,000. A $500 portfolio paying $36/year is losing 7.2% annually in fees before any investment return. This makes the break-even on investing nearly impossible for very small balances.

Round-Ups: Acorns’ Signature Feature

How it works:

Link your debit or credit card to Acorns
Every purchase rounds up to the nearest dollar
Round-up amounts accumulate until they hit $5
The $5 transfer goes into your Acorns portfolio

Example: You spend $4.30 at Starbucks, $12.70 at the grocery store, $3.50 on a streaming service = $0.70 + $0.30 + $0.50 = $1.50 in round-ups from three purchases. After 3–4 days of typical spending, you’ve accumulated $5 to invest.

Why it works behaviorally: You never see the money leave your account in a meaningful way. Over a year of average spending, round-ups can add $150–$600 to your portfolio automatically — with zero intentional effort.

Limitation: Round-ups alone are too small for meaningful wealth building. The average Acorns user accumulates $300–$500/year in round-ups. To build real retirement wealth, you need intentional recurring deposits — which any robo-advisor supports.

Portfolio Options

Acorns offers 5 portfolio options built from low-cost ETFs:

Portfolio	Stocks	Bonds
Conservative	28%	72%
Moderately Conservative	44%	56%
Moderate	60%	40%
Moderately Aggressive	76%	24%
Aggressive	100%	0%

Acorns uses primarily iShares and Vanguard ETFs with expense ratios of 0.03–0.07%. These are the same quality funds used by Betterment and Wealthfront.

Found Money: Partner Rewards

Acorns Found Money allows partner brands (Amazon, Airbnb, Chevron, Walmart, Nike, and 350+ others) to invest a percentage of your purchase directly into your Acorns account:

Similar to credit card cashback — but deposited as an investment
Percentages vary by partner (typically 1–10%)
No action required beyond shopping at partners

Over a year of regular shopping, Found Money can add $25–$100 to your account at typical usage levels.

Acorns IRA and Early Accounts

IRA Accounts

The $3/month plan includes Roth IRA, Traditional IRA, or SEP-IRA with the same portfolio options as the taxable account.

Acorns Early (Custodial Accounts)

Acorns Early provides custodial investment accounts for children — a UTMA/UGMA account opened by a parent or guardian. These invest in the same ETF portfolios as adult accounts. This differentiates Acorns from Betterment and Wealthfront (which don’t offer custodial accounts) but is less robust than Fidelity’s custodial account offering.

Acorns vs Betterment vs M1 Finance

	Acorns	Betterment	M1 Finance
Fee	$3/month ($36/yr)	0.25%	$0 / $3/mo
Cheaper above	N/A	$14,400	$14,400
Round-up investing	Yes	No	No
Tax-loss harvesting	No	Yes	No
Portfolio control	None	Low	Full
Custodial accounts	Yes	No	No
Minimum	$0	$0	$100

Who Acorns Is Best For

Strong match:

Complete beginners who have never invested and need the round-up habit to start
Young adults with irregular income who benefit from micro-investing
Parents who want a custodial account for children alongside their own account
Investors with under $5,000 who value simplicity over optimization

Graduate when:

Your portfolio exceeds $14,400 (Betterment becomes cheaper in absolute dollar terms)
You want tax-loss harvesting (Betterment or Wealthfront)
You want portfolio control (M1 Finance)
You want zero fees (Fidelity Go)
