What Is Acorn Investing and How It Works

What Is Acorn Investing

Acorn investing refers to using the Acorn app, a micro-investing platform that lets users invest small amounts of money, often rounded-up spare change from everyday purchases, into diversified exchange-traded funds. The service automates investing so that users can build a portfolio without actively managing trades or selecting individual stocks. It is designed for beginners who want to start investing with minimal capital and effort.

How Acorn Investing Works

Users link a bank account or debit card to the Acorn app. When they make a purchase, Acorn rounds the transaction up to the nearest dollar and invests the difference into a selected portfolio. Users can also set up recurring automatic investments, known as recurring deposits, to contribute a fixed amount on a regular schedule. The app offers a small number of pre-built ETF portfolios that are diversified across asset classes and risk levels, so users do not need to pick individual funds themselves.

Acorn Investment Portfolios and Features

Acorn provides several portfolio options that mix different ETFs based on a user's stated risk tolerance. Portfolios typically include a mix of domestic and international stocks and bonds. Key features include automatic recurring investments, round-up investing, and the ability to invest in individual ETFs or stocks once the account balance supports it. Acorn also offers retirement accounts, such as Individual Retirement Accounts, in addition to the standard taxable investment account.

Fees and Costs

Acorn charges a monthly subscription fee that varies by account type, typically ranging from around $1 to $5 per month, with some plans costing more when they include additional services like retirement accounts or checking features. Because the fee is a flat monthly amount rather than a percentage of assets, it can represent a significant share of a small balance, which matters for users with very low investment amounts.

Who Is Acorn Investing Best For

Acorn investing is best suited for beginners who want to start investing with small amounts of money and prefer an automated, hands-off approach. It may be less ideal for users with larger portfolios who can access lower-cost brokerage platforms with per-trade or percentage-based fees. People who already invest regularly through an employer-sponsored retirement plan or a low-cost brokerage may find Acorn useful for casual, incremental investing rather than as a primary investment vehicle.
