A robo-advisor is an automated digital investment advisory program. It usually collects information about goals, time horizon, finances and risk tolerance through an online questionnaire, recommends a portfolio and manages it under an advisory agreement. Automation can reduce minimums and operating costs, but it does not remove market risk or guarantee that the recommendation fits your full financial situation.
How a robo-advisor works
A typical workflow is:
- You answer questions about goals, time horizon, income, assets and tolerance for loss.
- The program assigns a risk profile and target asset allocation.
- The account buys a portfolio, often using exchange-traded funds.
- Software monitors allocation and rebalances under stated rules.
- Optional services may include recurring deposits, tax-loss harvesting, cash management or access to a human professional.
The questionnaire is an input, not a complete financial plan. Test how answers change the recommendation and correct any assumption that does not reflect your debts, emergency needs, taxes or other accounts.
Understand the complete fee stack
Robo-advisors may charge a percentage of assets, a monthly subscription or both. Add fund expense ratios, bid-ask spreads, account fees, transfer or closure costs and any cash drag.
A flat subscription has a higher effective percentage on a small balance. For example, $60 per year equals 1.20% of a $5,000 balance before fund costs, but 0.12% of $50,000. The SEC warns that subscription fees can consume a significant share of a small account. Compare annual dollars at your expected balance rather than relying on a low monthly headline.
Examine the portfolio, not just the risk label
Ask for the target allocation, eligible funds and rebalancing policy before funding. Check:
- stock, bond, cash and other asset weights;
- domestic and international exposure;
- fund expense ratios and trading spreads;
- whether affiliated or proprietary funds are favored;
- how much remains in cash and whether the provider benefits from that cash;
- what triggers rebalancing and whether changes create taxable sales;
- whether the same questionnaire answer can lead to a materially different portfolio later.
A portfolio called conservative can still lose money. Labels are provider-specific and do not replace a drawdown estimate or review of the underlying funds.
Tax-loss harvesting and account location
Automated tax-loss harvesting sells an investment at a loss and buys another exposure under the program's rules. Its value depends on your tax situation, holding period and other accounts. Purchases by you, a spouse or another automated account can complicate wash-sale analysis. Rebalancing can also realize gains in taxable accounts.
Ask whether the service coordinates across all accounts or sees only assets it manages. Retirement and taxable accounts may need different treatment. Tax features are not a reason to ignore overall fees or portfolio fit.
Registration, conflicts and human help
In the United States, research the adviser through Investor.gov's IAPD database and read Form ADV and Form CRS where applicable. Identify the legal adviser, custodian and affiliated broker. Automation does not exempt an adviser from applicable securities laws.
Conflicts can arise from proprietary funds, affiliated cash programs, referral payments or revenue-sharing. Review how the firm is compensated and whether a lower-cost equivalent portfolio is available.
Human support varies from none to scheduled access with a professional, sometimes only above a balance threshold. Confirm who can answer allocation, tax, transfer and account-security questions and how urgent issues are handled.
Operational and exit risks
Document account recovery, multi-factor authentication, outage procedures and the custodian's role. Then examine the exit: can securities transfer in kind, will fractional shares be sold, are proprietary holdings portable, what fees apply and could liquidation create taxes? A small initial deposit and a support test can reveal friction before the balance grows.
Evaluation checklist
- Adviser and custodian verified in official records.
- Total annual cost calculated in dollars and as a percentage.
- Target allocation and underlying funds reviewed.
- Cash treatment and conflicts disclosed.
- Rebalancing and tax methods understood.
- Human support level matches your needs.
- Transfer-out and closure process saved.
- Possible loss fits your horizon and emergency-cash plan.
Bottom line
A robo-advisor can automate a diversified portfolio and routine rebalancing at a lower service cost than some traditional arrangements. The relevant comparison is the complete service: portfolio, all-in fees, conflicts, taxes, support and exit terms. Choose automation only after the underlying allocation makes sense without the marketing label.
