How does a robo-advisor work?

A robo-advisor works in three steps: (1) Onboarding — you complete a questionnaire about your investment timeline, risk tolerance, and goals; (2) Portfolio construction — the algorithm assigns you a model portfolio (e.g., 80% stocks / 20% bonds) using low-cost index ETFs from Vanguard, iShares, or similar providers; (3) Ongoing management — the robo-advisor automatically rebalances your portfolio when allocations drift from targets and reinvests dividends. Most also offer tax-loss harvesting on taxable accounts.

Are robo-advisors safe?

Robo-advisors are as safe as traditional brokerages. Accounts are protected by SIPC (Securities Investor Protection Corporation) up to $500,000 per account type against broker failure — this protects against the broker going bankrupt, not against investment losses. Major robo-advisors including Betterment, Wealthfront, and Schwab Intelligent Portfolios are registered investment advisors (RIAs) with the SEC. Your investments are held in your name — not the robo-advisor's.

Is a robo-advisor better than a financial advisor?

A robo-advisor is better for: investors with straightforward portfolios, those who need low-cost hands-off management, investors with under $100,000 who do not meet human advisor minimums, and those comfortable with digital-only service. A human financial advisor is better for: complex situations (business exit, divorce, estate planning, Social Security optimization, tax strategy across multiple accounts), behavioral coaching during market downturns, and investors with $500,000+ who benefit from comprehensive planning.

How much does a robo-advisor cost?

Robo-advisor fees range from 0.00% (Schwab Intelligent Portfolios, SoFi, Fidelity Go for accounts under $25K) to 0.40% AUM (Betterment Premium, E*TRADE Core Portfolios). The most popular robo-advisors — Betterment and Wealthfront — charge 0.25% AUM. On a $50,000 portfolio at 0.25%, that is $125/year. ETF expense ratios (typically 0.03%–0.20%) are separate and paid to the fund providers.

What Is a Robo-Advisor? 2026 — How Automated Investing Works

Q: What is a robo-advisor?

A robo-advisor is an automated investment service that builds and manages a diversified portfolio of low-cost ETFs on your behalf. You answer questions about your goals, timeline, and risk tolerance, and the algorithm allocates your money across asset classes. Robo-advisors rebalance automatically and most offer tax-loss harvesting on taxable accounts. They charge much less than human advisors — typically 0.00%–0.40% AUM vs. 0.75%–1.50% for traditional wealth managers.

A robo-advisor is an automated investment platform that builds and manages a diversified portfolio of low-cost ETFs on your behalf. You answer a questionnaire, the algorithm constructs your portfolio, and the robo-advisor handles rebalancing and tax-loss harvesting automatically. Most robo-advisors charge 0.00%–0.25% AUM — a fraction of the 0.75%–1.50% charged by traditional financial advisors.

Bottom line: Robo-advisors are ideal for straightforward, long-term investing at minimal cost. For complex financial planning — retirement income strategy, estate planning, Social Security timing, tax planning across multiple accounts — a human financial advisor adds value robo-advisors cannot replicate.

How Robo-Advisors Work (Step by Step)

Sign up and complete questionnaire — You answer 5–15 questions about your investment timeline (when you need the money), risk tolerance (how you would react to a 30% drop), and goals (retirement, house purchase, general wealth building).
Portfolio assignment — The algorithm assigns you a model portfolio based on your answers. Example: a 35-year-old saving for retirement might receive an 85% stocks / 15% bonds allocation.
Purchase execution — The robo-advisor purchases a basket of low-cost index ETFs matching your target allocation. For example: US stocks (total market ETF), international stocks, bonds, and possibly REITs.
Automatic rebalancing — As markets move, your allocation drifts. If stocks rise and your equity allocation reaches 90%, the robo-advisor sells stocks and buys bonds to return to your 85/15 target.
Tax-loss harvesting — In taxable accounts, the robo-advisor automatically sells investments at a loss to generate capital losses that offset gains elsewhere on your tax return, then immediately purchases similar (but not identical) investments to maintain market exposure.
Dividend reinvestment — Cash dividends are automatically reinvested into your portfolio.

You have struggled to stay invested during market downturns and need behavioral coaching
