A robo-advisor is an online service that asks you questions about goals, timeline and risk tolerance, then invests your money in a portfolio of low-cost funds and manages it automatically. Well-known examples include Betterment, Wealthfront, Schwab Intelligent Portfolios, Vanguard Digital Advisor and Fidelity Go.
What they do well
- Low cost compared with traditional advisors. Many charge about 0.25% a year on top of fund expenses, versus around 1% for many human advisors. Some charge nothing for the advice itself but make money elsewhere.
- Instant diversification across US and international stocks and bonds.
- Automatic rebalancing back to your target mix (see rebalancing).
- Tax-loss harvesting in taxable accounts on many platforms.
- Behavioral guardrails. Less temptation to tinker or panic.
- Low minimums, often $0 to $500.
The limits
- Narrow scope. A questionnaire cannot handle stock options, a business sale, an inheritance, estate planning or a divorce.
- Still a fee. 0.25% on $300,000 is $750 a year, every year. A single target-date fund or a few index funds can do most of the same for less.
- Cash allocations. Some “free” robo-advisors keep a sizable share of your money in cash, earning the provider interest. In 2022 the SEC fined Schwab for not properly disclosing how its cash allocation worked.
- Limited human help, sometimes available only on premium tiers.
- Your questionnaire answers drive everything. Overstating your risk tolerance leads to a portfolio you will not stick with.
Who they suit
- Beginners who want a hands-off, diversified start.
- People who know they would not rebalance on their own.
- Investors with sizable taxable accounts who benefit from tax-loss harvesting.
Who might skip them
- Disciplined DIY investors comfortable with a few index funds.
- People with complex finances who need a human planner (often a hybrid service makes sense).
Before you sign up
- Compare the total cost: advisory fee plus fund expense ratios.
- Check how much sits in cash, and what it earns.
- Confirm the firm is registered: search it on the SEC’s Investment Adviser Public Disclosure site.
- Read the Form CRS, a short document that summarizes fees and conflicts.
