What is Acorns and How Does It Work?

What if every time you bought a coffee, a few spare cents were automatically invested toward your future? That’s the simple but powerful idea behind Acorns — an app that helps everyday users grow wealth effortlessly.

Founded in 2014 in California, Acorns popularized micro-investing, letting users round up spare change from daily purchases and invest it automatically in diversified portfolios. The app’s goal is to make saving and investing accessible to everyone, regardless of income or experience.

By 2025, Acorns has become one of America’s leading personal finance platforms, offering automated investing, retirement accounts, banking, and family savings plans. It focuses on building good financial habits through automation rather than requiring expert-level knowledge.

By the end of this article, you’ll understand what Acorns is, how it works, how it makes money, and how you can build your own Acorns-like investing app with Miracuves in 3–6 days.

What is Acorns? The Simple Explanation

Acorns is a U.S.-based micro-investing and savings app that helps users grow wealth automatically by investing spare change from everyday purchases. Whenever you buy something using a linked debit or credit card, Acorns rounds up the transaction to the nearest dollar and invests the difference into a diversified portfolio.

The core problem Acorns solves is the difficulty of consistent saving and investing. Many people struggle to invest regularly or don’t know where to start. Acorns automates that process — turning small, frequent contributions into long-term investments.

Its primary users include students, young professionals, and first-time investors who want to build financial habits with minimal effort.

As of 2025, Acorns manages over $9 billion in assets for millions of users and has grown into a complete financial wellness platform. It now offers retirement accounts, checking accounts, and family investment plans — all designed to simplify money management.

Acorns succeeded because it removes friction. It made investing as effortless as spending, helping users save without even thinking about it.

How Does Acorns Work? Step-by-Step Breakdown

Acorns operates by connecting to your debit or credit card, rounding up each purchase to the nearest dollar, and investing the leftover change into diversified portfolios managed by experts. It’s designed to make investing automatic and painless.

For Users

1. Account Setup
Users download the Acorns app, create an account, and link their spending card or bank account. The setup takes just a few minutes, and Acorns immediately starts tracking purchases for round-ups.

2. Round-Ups and Auto-Investments
When a purchase is made — say, $3.60 for coffee — Acorns rounds it to $4.00 and invests the $0.40 difference into an ETF-based investment portfolio. Users can also set recurring deposits or one-time boosts.

3. Portfolio Selection
Acorns offers five risk-based portfolios: Conservative, Moderately Conservative, Moderate, Moderately Aggressive, and Aggressive. Each portfolio includes ETFs from trusted providers like Vanguard and BlackRock.

4. Acorns Later (Retirement)
Acorns Later lets users open an IRA (Traditional, Roth, or SEP) and automatically invest in tax-advantaged accounts based on income and goals.

5. Acorns Checking
The Acorns Checking account includes a debit card that integrates with round-ups, direct deposits, and automatic investing — combining banking and investing in one.

6. Acorns Early (Family Accounts)
Parents can set up custodial investment accounts for children, teaching them about saving and wealth growth from an early age.

7. Education and Insights
Through the “Grow” section, Acorns provides educational content to improve users’ financial literacy.

For Service Providers / Partners

Acorns partners with financial institutions, merchants, and ETF providers to manage portfolios, process payments, and offer brand-based cashback (“Found Money”) when users shop with participating companies.

Technical Overview (Simplified)

Acorns runs on a cloud-based, API-driven platform using secure banking integrations to connect user accounts and automate investments. Transactions are processed through PCI-compliant gateways, and investments are executed via registered brokers and custodians.

Machine learning helps personalize portfolio recommendations and analyze user spending behavior to optimize savings potential.

Acorns’ Business Model Explained

Acorns makes money by combining subscription-based revenue with partnerships, interchange fees, and investment-related income — all while keeping the app free of hidden charges. Its business model focuses on scale and automation, generating profit from millions of small investors rather than large accounts.

1. Subscription Plans

Acorns offers a tiered monthly subscription model that gives users access to different features:

• Personal ($3/month): Includes Invest, Later, and Checking accounts.
• Family ($5/month): Adds Acorns Early for kids’ investment accounts.

These predictable monthly fees make up the core of Acorns’ revenue stream.

2. Interchange Revenue

When users spend with the Acorns Visa debit card, the company earns a small percentage from merchants through interchange fees — just like traditional banks do.

3. Found Money Partnerships

Acorns partners with brands such as Nike, Walmart, and Airbnb. When users shop through Acorns, these brands invest a small percentage of the purchase amount back into the user’s Acorns account. Acorns earns a commission for facilitating these referrals.

4. Management and Advisory Fees

While Acorns doesn’t charge direct trading commissions, it earns through small advisory and management fees included in its subscription plans.

5. Interest on Cash Balances

Acorns earns interest on the uninvested cash held in user accounts before it’s deployed into investments.

6. Acorns Later and Early

By expanding into IRAs and family accounts, Acorns attracts long-term customers who increase recurring revenue and retention rates.

7. Scale Efficiency

With millions of users and automated systems, Acorns runs on minimal operational costs compared to traditional investment firms, leading to higher margins.

As of 2025, Acorns generates tens of millions in monthly recurring revenue, driven primarily by subscription growth and partnerships.
