Approach
Acorns invests your spare change through round-ups: link your cards, and every purchase rounds up to the nearest dollar with the difference invested. The minimum to start is $0. Betterment takes a goal-based approach: set financial goals (retirement, emergency fund, major purchase) and Betterment builds and manages a portfolio tailored to each goal. Minimum deposit is $0 but the platform shines with $1,000+.
Portfolios
Acorns offers 5 pre-built portfolios (Conservative to Aggressive) using Vanguard and iShares ETFs. No customization possible. Betterment offers core portfolio, socially responsible investing, Goldman Sachs Smart Beta, BlackRock Target Income, and a flexible portfolio where you can adjust individual asset class weights. Betterment gives significantly more investment choice.
Tax optimization
Betterment offers tax-loss harvesting on all accounts (a major feature that typically saves 0.5-1.5% annually on taxable accounts). Tax-coordinated portfolios optimize asset placement across taxable and tax-advantaged accounts. Acorns offers no tax-loss harvesting. For taxable accounts with $10,000+, Betterment's tax optimization alone justifies the difference.
Fees
Acorns: $3-12/month flat fee. On a $1,000 balance, that is 3.6-14.4% annually. On $10,000, it is 0.36-1.44%. Betterment: 0.25% annually. On $10,000, Betterment costs $25/year vs Acorns at $36-144/year. Betterment is cheaper for any balance above approximately $1,500.
Our verdict
Start with Acorns if you have never invested before and need training wheels: the round-up mechanic creates an investing habit effortlessly. Switch to Betterment once your balance passes $1,500-3,000, where Betterment becomes cheaper AND offers tax-loss harvesting, better portfolios, and more features. Betterment is the better long-term platform; Acorns is the better starting point.
