Robo-Advisers vs. Human Advisers: What Each Does and Doesn't Do
1 / 7
What is the difference between a robo-adviser and a human adviser?
- A robo-adviser uses algorithms and an online questionnaire to build and rebalance a portfolio, usually of index funds or ETFs.
- A human adviser gives advice shaped by conversations about your full situation, often alongside portfolio management.
- Robo-advisers are generally registered investment advisers, subject to the same fiduciary framework as other advisers.
- Many firms now blend the two, pairing automated portfolios with access to people.

What is the difference between a robo-adviser and a human adviser?
- A robo-adviser uses algorithms and an online questionnaire to build and rebalance a portfolio, usually of index funds or ETFs.
- A human adviser gives advice shaped by conversations about your full situation, often alongside portfolio management.
- Robo-advisers are generally registered investment advisers, subject to the same fiduciary framework as other advisers.
- Many firms now blend the two, pairing automated portfolios with access to people.
What do robo-advisers do well?
- Automated rebalancing and dividend reinvestment keep a target mix without manual work.
- Many offer automated tax-loss harvesting in taxable accounts, subject to the wash-sale rules.
- Fees and account minimums are often lower than those of traditional advisory relationships.
- Rules-based investing can reduce the urge to react to headlines.
What are their limits?
- Advice rests on questionnaire answers, which may miss outside assets, company stock, or near-term cash needs.
- Most don't address equity compensation decisions such as option exercises, RSU sales, or 10b5-1 plans.
- Coordination across multiple custodians, account types, and a spouse's holdings is often limited.
- Estate, insurance, and tax guidance, where offered, tends to be general rather than specific to you.
When can a human adviser add value?
- When decisions interact, such as stock options, a liquidity event, a move between states, or a retirement date.
- When you want one person coordinating with your CPA and estate attorney.
- When market stress tempts changes that would be hard to reverse.
- Whether that value exceeds the added cost depends on your situation and the adviser, and it isn't assured.
How do you check out an adviser?
- Registration and disciplinary history are searchable on the SEC's Investment Adviser Public Disclosure site and FINRA BrokerCheck.
- Form ADV Part 2A describes services, fees, and conflicts, and Form CRS summarizes them in a few pages.
- Ask how the adviser is paid; fee-only advisers take no commissions, though every fee model carries some conflict.
- Brokers must act in your best interest when recommending under Regulation Best Interest, while advisers owe an ongoing fiduciary duty.
Can you combine the two?
- Some people pair a low-cost automated portfolio with separately paid planning by the hour or project.
- Credentials such as CFP or CFA signal training but don't replace checking disciplinary history.
- The fit can change over time; complexity, not account size alone, drives the need for advice.
Key takeaways
- Robo-advisers handle portfolio mechanics efficiently at relatively low cost.
- Human advisers add planning, coordination, and judgment, at a higher price.
- Check registration, Form ADV, Form CRS, and how the adviser is paid.
- Match the service to how complex your finances are.
