Know what you are buying
The Investor.gov glossary defines a robo-adviser as an automated digital investment advisory program. Typically, you complete an online questionnaire covering goals, investment horizon, income, assets, and risk tolerance, and then the platform creates and manages a portfolio for you.
But that definition covers a range of services. One platform may offer discretionary investment advice, meaning it has legal authority to trade on your behalf. Another may provide only model portfolios, calculators, or trade automation without acting as a fiduciary. A third might bundle a brokerage account, advisory account, bank sweep, and access to a human adviser in one product.
Before funding an account, identify these specifics:
- Legal entity and registration status (check SEC or state regulator databases)
- Whether the account is advisory, brokerage, or a hybrid
- Whether a human adviser is available and at what cost
- Whether the platform has discretion to trade or requires you to approve each transaction
- Which portfolio models or ETFs are used
- How the service handles cash (sweep account, money market, or interest-bearing feature)
- How often rebalancing occurs and what triggers it
- How taxes are handled (loss harvesting, gain deferral, reporting)
- How to close, transfer, or change risk level
Read the questionnaire assumptions
The SEC Investor Bulletin on robo-advisers encourages investors to understand how the tool uses information about goals and risk. A short questionnaire can be convenient, but it may miss details that matter for taxes, concentration risk, debt, estate planning, or country-specific rules.
Check whether the questionnaire covers:
- Goal and time horizon (retirement, education, home purchase, etc.)
- Need for emergency cash reserves
- Income stability (steady salary vs. variable income)
- Existing investments (outside the robo-adviser)
- Taxable versus retirement account type (Roth, traditional, SEP, etc.)
- Risk tolerance and capacity for loss (how much loss you can afford)
- Withdrawal plans (lump sum, periodic, or not yet)
- Concentrated positions or employer stock holdings
- Preference for human advice or self-directed access
If the questionnaire skips several of these items, the resulting portfolio recommendation may not align with your full financial picture. For example, a person with a concentrated single stock position may need very different allocation advice than someone with only diversified index funds.
Compare fees and underlying funds
FINRA explains that brokerage and advisory accounts can charge differently. Advisory fees are often a percentage of assets under management (AUM) charged periodically, while brokerage accounts have transaction costs, commissions, or markups. For automated investing, the total cost includes multiple layers.
Collect these figures before funding:
- Advisory fee (usually 0.15% to 1.0% annually of AUM)
- Fund expense ratios (underlying ETFs or mutual funds)
- Cash allocation and cash yield (the platform may hold a percentage in cash that earns a lower yield)
- Tax-loss harvesting fee or availability (some charge extra, others include it)
- Human adviser add-on cost (if you want to speak to a person)
- Account closure or transfer fee (usually $50–$100)
- Underlying ETF bid-ask spreads (can add cost at trade execution)
- Margin, borrowing, or securities lending settings (if enabled, they introduce leverage and counterparty risk)
A low advisory fee can be offset by high underlying fund costs or a large cash allocation that earns near zero. For instance, a 0.30% advisory fee might look low compared to a human adviser, but if the platform's funds have expense ratios averaging 0.20% and another platform uses only Vanguard ETFs at 0.03%, the total cost difference matters over time. Also, if the platform holds 10% cash that earns 0.1% while inflation runs 2%, the effective return drag is significant.
Understand the algorithm and controls
FINRA's alert on automated investment tools notes these tools range from simple calculators to portfolio selection and online investment management programs. Investors should understand the tool's assumptions and limitations.
Ask the following about the algorithm:
- Rebalancing frequency: How often does the platform rebalance? Is it calendar-based (quarterly, annually) or threshold-based (drift of 1-2% triggers rebalance)? During volatile markets, frequent rebalancing can generate more trades and potentially higher tax costs.
- Portfolio change triggers: What events cause the algorithm to change your allocation? A change in risk profile, a large deposit or withdrawal, or market conditions?
- Deviation from target: Can the portfolio drift significantly from the target allocation before a rebalance occurs? Some platforms allow drift up to 10%, others 5%.
- Proprietary funds: Does the platform use its own in-house funds or affiliated ETFs? This creates a potential conflict of interest if the platform pushes higher-fee proprietary products.
- Exclusion options: Can you exclude certain securities, industries, or sectors for ethical, religious, or personal reasons? Some robo-advisers offer ESG (environmental, social, governance) screens, others do not.
- Market stress handling: How does the system behave during sharp market downturns? Does it automatically reduce risk, or does it stay the course? Automated rebalancing during a crash could force you to sell at low prices if you are not prepared.
- Deposits and withdrawals: How are deposits invested (proportionally vs. lump sum) and how are withdrawals funded (from cash first, then sell positions)?
Automation is not a substitute for suitability in every situation. If you need estate planning, complex tax advice, concentrated stock planning, business-owner planning, cross-border considerations, or help with Social Security claiming strategy, a simple digital model is likely insufficient. A human adviser may be necessary to address those complexities.
Red flags to pause on
If you encounter any of these warning signs, consider delaying funding until you obtain clarification:
- The tool promises market-beating returns or downside protection (no algorithm reliably predicts short-term market movements, and any guarantee of downside protection likely involves additional costs or insurance products).
- The questionnaire is extremely short (three to five questions) for a portfolio that claims to be fully customized, especially if your situation includes multiple accounts, a family, or concentrated holdings.
- Fees are quoted as a percentage without mentioning underlying fund expenses. A 0.25% fee sounds low, but if the fund costs 0.50% on top of that, the total 0.75% is competitive with many human advisers.
- The platform does not disclose whether it uses affiliated funds. This conflict of interest could inflate costs or reduce diversification.
- Tax-loss harvesting is marketed heavily without explaining its limitations. Loss harvesting can generate tax savings, but only if you have realized gains elsewhere, and the benefit may be offset in future years when you sell the harvested funds.
- You cannot find clear instructions for changing risk level, stopping automatic deposits, or transferring assets out. This suggests poor transparency or a lock-in mechanism.
- The service blurs the line between general education, brokerage execution, and investment advice. For example, a calculator that suggests a portfolio model without a fiduciary duty may not be acting in your best interest. A robo-adviser registered with the SEC as an investment adviser must act as a fiduciary, but some platforms operate only as broker-dealers.
The exit terms
Before you open an account, understand how you can leave. Robo-advisers vary in how they handle account closures:
- Is there a closure or transfer fee?
- Can you transfer assets in-kind to another brokerage, or must you liquidate?
- How long does the process take?
- Does the robo-adviser allow automated withdrawals or periodic transfers?
- What happens to a systematically withdrawn income stream if you decide to leave?
If the exit terms are punitive or unclear, that is a reason to reconsider. Some platforms offer free transfers to encourage long-term retention, while others charge a flat fee for outgoing transfers.
Verification note
This checklist is based on publicly available investor education materials from the SEC, FINRA, and Investor.gov. It does not evaluate or rank specific robo-adviser providers. Fee structures, fund expense ratios, tax rules, regulatory status, and platform features change over time. Before funding an account, verify the current fee schedule, registration status, and portfolio models on the platform's official regulatory filings (such as Form ADV for investment advisers). Be aware that tax implications depend on your individual jurisdiction and tax bracket; consult a qualified tax professional for personalized advice.
Bottom line
Automated investing is strongest when your goal is clear, your account type is simple, and the platform fully discloses fees, portfolio construction, rebalancing methodology, cash treatment, and exit terms. Do not select a robo-adviser based solely on a ranking or a low headline fee. Use this checklist to verify how the service actually works, whether the questionnaire covers enough of your financial picture, and whether any conflicts of interest exist. The convenience of automation should not come at the expense of understanding what you own and what you pay.
