How do the best robo-investors compare?
What makes a robo-advisor “best” in the US?
A top robo-advisor in the US stands out by delivering the following four elements:
- Low, transparent fees: Competitive pricing at 0.20%–0.40% annually or low flat fees, with no trading commissions.
- Strong portfolio construction: Diversified ETF portfolios, automatic rebalancing, and risk-based allocation built for long-term investing.
- Tax and account efficiency: Support for taxable accounts and IRAs, plus features like tax-loss harvesting where available.
- Security and reliability: SEC oversight, SIPC protection up to $500,000, and stable, well-established US operators.
Acorns - Best for effortless micro-investing and beginners
Acorns is a US-based robo-advisor and micro-investing platform designed to help beginners build long-term investing habits with minimal effort. Its core proposition is automation: spare change investing through Round-Ups, simple ETF portfolios, and a mobile-first experience that combines investing, retirement, and banking in one app.
Acorns uses a flat monthly subscription model, rather than the percentage-based fees common among most robo-advisors. This makes costs predictable, but potentially expensive for small balances.
Acorns offers three plans:
- Personal: $3 per month
- Personal Plus: $6 per month
- Premium: $12 per month
In addition to the subscription fee, investors also pay the underlying ETF expense ratios, which range from 0.04% to 0.22%, depending on the portfolio. These fees are charged by ETF providers, not Acorns itself. There are no trading commissions for managed portfolios.
However, Acorns charges a transfer-out fee of $50 per ETF when moving assets to another brokerage. Because fees are flat, the effective cost can be high at low balances. For example, a $3 monthly fee on a $500 portfolio equals 7.2% per year, well above the industry norm of around 0.25% for AUM-based robo-advisors.
Acorns portfolios are constructed using modern portfolio theory, which aims to balance expected return and risk through diversification.
During onboarding, users answer questions about:
- Financial goals
- Time horizon
- Risk tolerance
Acorns assigns one of several model portfolios ranging from conservative to aggressive. Portfolios include:
- US and international equity ETFs
- Bond ETFs
- Real estate investment trusts (REITs)
- Up to 5% allocation to a Bitcoin-linked ETF in eligible portfolios
Portfolios are automatically rebalanced, ensuring allocations stay aligned with the selected risk profile. Users cannot select individual ETFs or customize sector exposure.
Acorns offers very limited tax optimization compared with many competitors.
- Tax-loss harvesting: Not available
- Advanced tax strategies: Not supported
- Capital gains management: Automated through portfolio management only
For retirement planning, Acorns provides:
- Traditional, Roth, and SEP IRAs via Acorns Later
- A built-in investment calculator showing projected balances over time
- IRA contribution matching at higher tiers:
- 1% match on eligible contributions (Personal Plus)
- 3% match (Premium), subject to limits and conditions
While the IRA match can partially offset fees, investors seeking sophisticated tax strategies may find Acorns less competitive than platforms like Wealthfront or Betterment.
Acorns is designed as a low-touch, fully automated investment platform and does not offer access to certified financial planners or dedicated advisors.
Customer support is available through:
- Live chat
- Email support
- In-app help centre and FAQs
Higher-tier subscribers may receive priority support and access to live educational sessions, but there is no one-on-one financial advice. This contrasts with some competitors that provide CFP access at higher balances or fees.
Acorns is best suited to:
- First-time investors with little or no investing experience
- People who struggle to save consistently and benefit from automation
- Mobile-first users who want a simple, all-in-one financial app
- Long-term savers using IRAs or custodial accounts via higher tiers
It is less suitable for:
- Investors with large portfolios
- Those seeking tax-loss harvesting or advanced planning tools
- Users who want control over ETF selection or portfolio design
Betterment - Best for goal-based investing with strong tax tools
Betterment is one of the largest and most established robo-advisors in the US. Founded in 2008, it offers low-cost, goal-based investing with a strong focus on automation, tax efficiency, and long-term planning. The platform is designed for hands-off investors who want diversified portfolios, clear pricing, and scalable tools that grow with their finances.
Betterment uses a tiered pricing structure that combines percentage-based fees with a flat monthly charge for smaller balances.
For the Betterment Digital plan:
- 0.25% per year on balances over $24,000, or if you set up recurring monthly deposits of $250 or more
- Otherwise, a $5 per month flat fee applies
This means smaller balances can face a higher effective fee. For example, paying $5 per month on a $10,000 balance equals roughly 0.6% annually, which is higher than the industry average.
For larger portfolios, Betterment offers progressive fee discounts:
- 0.15% on balances between $1 million and $2 million
- 0.10% on balances above $2 million
In addition to advisory fees, Betterment portfolios include ETF expense ratios, ranging from 0.04% to 0.17% for the Core Portfolio. These are charged by ETF providers and deducted automatically.
Betterment also charges a $75 outbound transfer fee when moving investments to another brokerage. There are no fees for deposits, withdrawals, rebalancing, or dividend reinvestment.
Betterment builds portfolios using modern portfolio theory, emphasising diversification and risk-adjusted returns. During onboarding, users define:
- Financial goals (e.g., retirement, emergency fund, general investing)
- Time horizon
- Risk tolerance
Betterment allocates investments across 12 asset classes using low-cost ETFs. Portfolios are managed automatically with:
- Automatic rebalancing, triggered when allocations drift by 3% or more
- Dividend reinvestment
- Ongoing adjustments as contributions, withdrawals, or market movements occur
Beyond the Core Portfolio, Betterment offers:
- Flexible Portfolios, allowing limited adjustments to asset class weights
- Socially responsible portfolios (Broad Impact, Climate Impact, Social Impact)
- Crypto ETF portfolios holding Bitcoin and Ethereum ETFs
- Since late 2025, the ability to buy and sell individual stocks and ETFs within the Betterment app
Tax efficiency is one of Betterment’s strongest areas. Key tools include:
- Tax-loss harvesting on taxable accounts, included at no extra cost
- Tax-Coordinated Portfolio, an asset location strategy that places tax-efficient assets in taxable accounts and tax-heavy assets in retirement accounts (requires both account types at Betterment)
- Tax Impact Preview, which shows the potential tax consequences of portfolio changes before execution
- Charitable giving tool, allowing tax-efficient donations of appreciated securities
While Betterment does not offer direct indexing (available at some competitors for very large balances), its tax tools are among the most comprehensive available to mainstream robo-advisor users.
Support levels depend on the plan selected.
- Betterment Digital: No direct access to financial advisors. Support is provided via email and phone during business hours.
- Betterment Premium: Requires a $100,000 minimum and charges a 0.65% annual fee. Includes unlimited access to a team of Certified Financial Planners (CFPs) via phone, video, and email.
Premium advisors can help with:
- Retirement planning
- Education planning
- Goal prioritisation
- Basic estate planning and tax strategy discussions
Betterment Premium does not manage assets held outside the platform, but advisors can factor them into planning conversations.
Betterment is best suited to:
- Hands-off investors who want low-cost, automated investing
- Beginners, thanks to the $10 entry point and guided goal setup
- Long-term and retirement-focused investors
- Users who value tax optimization and goal-based planning
- Investors who may want to “graduate” to human advice later via the Premium plan
It may be less suitable for:
- Active traders or frequent stock pickers
- Investors seeking highly bespoke portfolio construction
- Users who want unlimited human advice without meeting a high balance threshold
Fidelity Go - Best for existing Fidelity clients wanting low-cost automation
Fidelity Go is Fidelity Investments’ robo-advisor, launched in 2016. It’s built for investors who want a hands-off portfolio with the comfort of a large, established US trading platform behind it. Fidelity Go combines an onboarding questionnaire (goals, risk tolerance, time horizon) with portfolios built from Fidelity’s own funds, and it becomes more compelling once balances reach $25,000 due to added human coaching and tax features.
Fidelity Go’s pricing is simple and balance-based:
- No advisory fee for balances under $25,000
- 0.35% per year once your balance reaches $25,000+ (35 basis points)
A key differentiator is the underlying investments. Fidelity Go portfolios use Fidelity Flex mutual funds, which have no expense ratios (or no fund management fees “in most cases”), meaning you may avoid the extra layer of ETF expense ratios that many robo-advisors pass through.
There are no additional account fees for things like setup, maintenance, trades, transfers of money, or closing (this can vary by account type and how you move assets, but the overall positioning is “low-fee, low-friction”).
The moment you cross $25,000, you move from “free” to a standard robo-advisor fee. If you are planning to stay just below that threshold, the cost difference can be material over time.
Fidelity Go builds your portfolio after you complete a short questionnaire about:
- Your investing goal(s)
- Time horizon
- Risk tolerance
Portfolios are allocated according to that profile and then managed on your behalf. Fidelity Go offers human portfolio oversight, with day-to-day trading and portfolio decisions handled by a dedicated Fidelity team (often described as a registered investment advisor unit within Fidelity).
Portfolio building blocks and diversification:
- Portfolios are built from Fidelity Flex mutual funds
- Coverage across four broad asset classes: domestic, foreign (international), bonds, and short-term/cash-like exposure
- Customers can choose from 16 portfolios (eight taxable and eight retirement)
Management features include:
- Automatic rebalancing to keep allocations aligned with the chosen strategy
- Periodic reviews to ensure the strategy still matches the client’s situation and goals
Fidelity Go is not designed for hands-on portfolio construction. You cannot pick individual holdings, and investment choice is restricted to the Fidelity Flex fund lineup used in the program.
Fidelity Go’s tax capabilities appear to be tier-dependent and updated over time.
- Tax-loss harvesting: Available only at $25,000+
- Tax-aware construction: Fidelity Go may use municipal bond funds in taxable accounts, which can help reduce taxable income versus fully taxable bond exposure
Planning tools are a stronger part of the Fidelity ecosystem than the robo itself:
- Goal setting and progress tracking
- Access to Fidelity’s broader education and planning resources
- Retirement planning support via Fidelity’s tools (especially relevant if you already hold IRAs or rollovers at Fidelity)
Fidelity Go may feel limited compared to robo-investors that provide tax tools with lower or no minimums.
Fidelity’s customer support footprint is one of the strongest among robo-advisors backed by major brokers:
- Phone support is described as 24/7
- Live chat is available Monday to Friday, 8 a.m. to 6 p.m. Eastern
- A thorough FAQ/help center
For investing guidance rather than customer service, the key threshold is $25,000:
- At $25,000+, users can access unlimited coaching sessions with Fidelity-trained advisors
These coaching sessions are positioned as goal and planning guidance rather than bespoke portfolio design. Fidelity Go remains an automated managed solution, not a fully personalized wealth management relationship.
Fidelity Go is best for:
- Existing Fidelity customers who want to manage multiple accounts under one login and one institution
- Beginner investors who want a low barrier to entry ($0 to open, $10 to start investing)
- Hands-off investors who prefer human oversight of portfolio decisions, rather than a purely algorithm-driven model
- Investors who expect to reach $25,000+, where coaching become part of the value proposition
It may be less suitable for:
- Investors who want ETFs, individual stocks, REITs, or crypto inside their robo portfolio (Fidelity Go is largely limited to Fidelity Flex funds)
- People looking for socially responsible investing (SRI/ESG) portfolio options
- Investors who want robust tax tools below $25,000, depending on current feature availability and eligibility rules
Schwab Intelligent Portfolios - Best for fee-free automated investing
Schwab Intelligent Portfolios is the automated investing service offered by Charles Schwab. It builds diversified ETF portfolios based on an investor’s goals, risk tolerance, and time horizon, and manages them automatically with rebalancing and dividend reinvestment. Its defining feature is that it charges no advisory or management fee, though portfolios include a required cash allocation.
Schwab Intelligent Portfolios does not charge an advisory or management fee, which is rare among mainstream robo-advisors. However, investors still incur indirect costs:
- ETF expense ratios: Portfolios are built using ETFs with an average expense ratio of around 0.12% annually, ranging from 0.04% to 0.16% depending on the strategy.
- Cash allocation impact: Each portfolio includes a mandatory cash allocation that is swept into Schwab’s cash program. While there is no explicit fee, this cash generally earns less than invested assets, which can reduce overall returns over time.
There are no commissions, account maintenance fees, or rebalancing fees.
Schwab Intelligent Portfolios uses an onboarding questionnaire to assess:
- Financial goals
- Time horizon
- Risk tolerance
Based on these, Schwab assigns a diversified ETF portfolio drawn from a broad universe of funds.
Portfolio characteristics include:
- Exposure to up to 20 asset classes
- Use of 51 ETFs across global equities, bonds, and alternative exposures
- Strategy groupings such as Global, US-focused, and Income-focused portfolios
Management is fully automated and includes:
- Automatic rebalancing
- Dividend reinvestment
- Ongoing monitoring to keep allocations aligned with the chosen strategy
Customization is limited. You cannot freely swap ETFs, although the ability to exclude up to three ETFs, which Schwab replaces with alternatives.
A key structural feature is the required cash allocation, ranging from 6% to more than 20%, depending on portfolio risk level. This can help reduce volatility but may also dampen long-term growth.
Schwab Intelligent Portfolios offers tax-loss harvesting, but only under specific conditions:
- Available only for taxable accounts
- Requires a minimum balance of $50,000
- Clients must opt in to the feature
Below this threshold, tax optimization is limited to general diversification and rebalancing.
Schwab also provides access to retirement calculators and planning tools through its broader platform, but the robo-advisor itself does not deliver personalized tax strategies or asset-location optimization.
Schwab provides strong customer support, but not personalized investment advice for robo-advisor users. Support options include:
- 24/7 phone and live chat support
- Access to Schwab representatives with securities licenses (Series 7/63 or 7/66)
- In-person assistance at Schwab branch locations
These representatives can help with account questions and platform use, but they do not offer customized portfolio advice or financial planning as part of Schwab Intelligent Portfolios.
Schwab Intelligent Portfolios is best suited to:
- Cost-conscious investors who want automated investing with no advisory fee
- Existing Schwab clients who want all accounts under one provider
- IRA investors, where the impact of cash drag may be less significant
- Hands-off investors who value diversification and automatic rebalancing
It may be less suitable for:
- Growth-focused investors who want to stay fully invested
- Investors with balances under $5,000
- Users who want personalized financial advice or planning
- Those seeking tax-loss harvesting at lower account balances
Wealthfront - Best for tax-efficient investing and advanced automation
Wealthfront is a robo-advisor built around automation and tax efficiency. It’s best known for daily tax-loss harvesting, optional direct indexing (stock-level tax-loss harvesting) at higher balances, and a strong suite of planning tools, including its Path financial planning dashboard and “Self-Driving Money” automation. Wealthfront also pairs its managed investing with a high-yield cash account and a separate DIY stock investing account.
Wealthfront’s standard managed investing fee is straightforward:
- 0.25% per year for automated investment management (deducted over time rather than billed upfront)
- Example: $100,000 managed = about $250/year in advisory fees
You’ll also pay the underlying fund costs:
- ETF expense ratios average 0.08% (these are charged by fund providers, not Wealthfront)
Notable fee exceptions and related products:
- No management fee or trade commissions for Wealthfront’s stock investing account (DIY investing inside Wealthfront)
- No annual/inactivity/account maintenance fees for the core platform experience
- Some Wealthfront speciality portfolios can have different pricing, but the core robo-managed service is the 0.25% baseline most investors will compare.
Wealthfront’s value proposition is less about being the cheapest and more about after-tax returns, because it leans hard into tax optimization.
Wealthfront starts with an onboarding questionnaire designed to gauge:
- Your goal(s)
- Time horizon
- Risk tolerance
Portfolios are built using ETFs across up to 12 asset classes, with a typical portfolio holding exposure to 6 to 8 asset classes depending on your settings.
Asset class coverage includes a mix of:
- US stocks, international stocks, emerging markets
- Bonds (including municipal bonds for taxable accounts)
- Inflation-protected securities, and sometimes alternatives such as real estate/natural resources
Management features include:
- Automatic rebalancing – threshold-based (rebalancing when allocations drift rather than on a fixed quarterly schedule)
- Rebalancing and dividend reinvestment often occur naturally during deposits, withdrawals, or reinvestment events, helping reduce unnecessary taxable gains in taxable accounts
Customization is a differentiator versus many robo-advisors:
- Wealthfront allows clients to add or remove certain ETF holdings, and users can build a portfolio from scratch within the Wealthfront framework.
- There are also separate product tracks beyond the core automated portfolio, including managed bond solutions and the option to combine DIY investing with a managed portfolio at the same provider.
Wealthfront’s automated investing may not invest every last dollar due to ETF fractional-share limitations, meaning a small amount of cash can remain uninvested.
Tax optimization is Wealthfront’s standout feature set, especially for taxable accounts.
Key tools include:
- Daily tax-loss harvesting on taxable accounts
- Stock-level tax-loss harvesting (direct indexing) available at no additional cost for taxable accounts with $100,000+
- Below $100,000, the platform may use a broad-market ETF instead
- A direct indexing approach can create more harvesting opportunities than ETF-only portfolios because it can harvest losses at the individual stock level, not just at the fund level.
- Tax-minimized transfers for new clients moving into existing holdings (designed to incorporate transferable securities where possible and manage capital gains sensitivity)
Planning tools are unusually broad for a robo-advisor:
- Path, Wealthfront’s planning dashboard, which can be used even without paying for portfolio management
- Goal planning tools covering retirement, home buying, college savings, and general savings
- “Self-Driving Money” automation that can route cash toward goals
Wealthfront is often strongest when you’re investing in a taxable account and care about after-tax outcomes, not just headline fees.
Wealthfront does not offer human financial advisors, even for an additional fee. What it does offer:
- Customer support
- “Product specialists” or licensed professionals may be available for platform support, but they do not provide personalized investing advice like a dedicated advisor or CFP relationship.
This is a key difference versus platforms like Betterment (Premium tier) or Fidelity Go.
Wealthfront is best for:
- Hands-off investors who want a strong automated robo experience
- Investors using taxable accounts, where Wealthfront’s tax optimization tools can matter most
- People who want planning tools alongside investing
- Investors who want both a managed portfolio and a DIY investing option in one place
- Families saving for college who want 529 plan management through a robo investing platform
It may be less suitable for:
- Investors who want access to a human advisor or CFP
- New investors who can’t meet the $500 managed account minimum
- Users who want the simplest possible “set-and-forget” with minimal product sprawl
Are robo-advisors safe?
Yes, US robo-advisors are considered safe from an operational and regulatory standpoint, provided they are properly regulated and use established custodians to hold client assets. However, safety relates to platform security and asset protection, not protection from market losses.
Regulation and oversight
US robo-advisors operate as registered investment advisers (RIAs) and are overseen by the Securities and Exchange Commission (SEC). This requires them to act as fiduciaries, disclose fees and risks clearly, and follow strict compliance rules. Many also fall under the supervision of the Financial Industry Regulatory Authority.
Investor protection
Investment accounts are protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 per customer, including $250,000 in cash, if a brokerage fails. This does not protect against market losses.
Cash balances held in robo-advisor cash or savings accounts are placed with partner banks and covered by the Federal Deposit Insurance Corporation (FDIC), up to $250,000 per bank, and sometimes more when funds are spread across multiple banks
Security and risks
Most robo-advisors use bank-grade security, including encryption, two-factor authentication, and continuous monitoring. Client assets are held separately from company funds, often with large third-party custodians.
The main risks to understand are:
- Portfolio values can fall during market downturns
- Automated strategies may underperform in certain conditions
- No guarantee of returns
Methodology - How we score robo-advisor platforms
Each robo-advisor in this guide was evaluated using a standardized scoring framework designed to reflect how real investors use automated investing platforms in the US.
Testing combined hands-on platform analysis, fee and cost modelling, feature-by-feature reviews, and regulatory and safety checks. Public disclosures, platform documentation, and user-facing tools were reviewed to ensure accuracy and consistency across providers.
Scoring framework
Each robo-advisor was assessed across the following categories, with adjustments made to reflect robo-investor functionality rather than active trading:
- Investing approach and portfolio construction: Asset allocation, diversification, rebalancing, and customisation options
- Platform design and usability: Onboarding process, mobile and web experience, and account management tools
- Account types and products: Taxable accounts, IRAs, cash management, and long-term planning features
- Tax optimization and planning tools: Tax-loss harvesting, asset location, and goal-based planning tools
- Fees and costs: Management fees, fund expenses, minimums, and cost transparency
- Safety and reliability: Regulatory oversight, asset protection, and operational safeguards
- Customer support and education: Access to guidance, support availability, and investor education resources
- Funding and withdrawals: Deposit methods, withdrawal speed, and transfer policies
Each category is scored out of 5, then weighted according to its importance for long-term, hands-off investing. The weighted scores are combined to produce the final overall rating.
This methodology prioritizes cost efficiency, portfolio quality, tax effectiveness, and platform reliability, ensuring rankings reflect practical value rather than promotional claims or short-term performance.
How to pick the right robo-advisor for you?
If you’re unsure which robo-advisor fits your needs, the quickest way to decide is to match your priorities with the platforms below. Each category groups 1–3 options that solve a specific investor problem, helping you narrow your choice without comparing every feature.
Best for beginners and first-time investors
- Acorns - Designed for people new to investing, Acorns removes friction by automating contributions through Round-Ups and recurring deposits. With no account minimum and investing triggered once balances reach $5, it’s built to help users form saving habits rather than optimize portfolios.
- Betterment - Betterment’s $10 minimum to start investing and goal-based onboarding make it accessible to beginners who want more structure than micro-investing. Automatic rebalancing and diversification across 12 asset classes help new investors stay invested without making decisions themselves.
Best for low fees and cost-conscious investing
- Schwab Intelligent Portfolios - Schwab stands out for charging $0 in advisory fees, which is rare among robo-advisors. Investors only pay underlying ETF expenses (averaging 0.12%). This appeals to long-term investors focused on minimizing ongoing costs, especially within IRAs where tax drag is less relevant.
- Fidelity Go - Fidelity Go charges no advisory fee for balances under $25,000, making it one of the lowest-cost entry points among major US providers. Even above that threshold, the 0.35% fee includes portfolio management and access to Fidelity’s broader planning ecosystem.
Best for tax-efficient investing in taxable accounts
- Wealthfront - Wealthfront is built around after-tax returns. It offers daily tax-loss harvesting on all taxable accounts and stock-level tax-loss harvesting (direct indexing) at $100,000+, a feature reserved for high-net-worth investors. ETF expense ratios average 0.08%, keeping total costs competitive.
- Betterment - Betterment provides tax-loss harvesting, asset location (Tax-Coordinated Portfolios), and tools like Tax Impact Preview, which shows potential tax consequences before changes are made. While it doesn’t offer direct indexing, it delivers strong tax optimization at a lower balance threshold than most competitors.
Best for investors who want guidance without full DIY control
- Fidelity Go - Once balances reach $25,000, Fidelity Go includes unlimited coaching sessions with Fidelity advisors at no extra cost. This suits investors who want human input on goals and planning without managing investments themselves.
- Betterment (Premium) - Betterment Premium offers access to Certified Financial Planners (CFPs) for households with $100,000+, at a lower cost than traditional advisory relationships. It’s a middle ground between a robo-investor and a full-service financial advisor.
How to start using a robo-advisor?
Getting started with a robo-advisor is designed to be quick and low-effort, even for first-time investors.
Most platforms let you set up an account, build a portfolio, and begin investing in under 15 minutes.
- Choose a platform that fits your goals: Compare robo-advisors based on fees, minimum balances, tax features, and whether you want optional human support. The right choice depends on whether you’re investing for the long term, retirement, or a specific goal like building wealth passively.
- Complete the onboarding questionnaire: You’ll answer questions about your income, time horizon, and risk tolerance. The robo-advisor uses this information to recommend a diversified portfolio aligned with your goals.
- Fund your account: Link a bank account and make an initial deposit, which can be as low as $0–$500 depending on the platform. Many robo-advisors also allow recurring deposits to automate investing.
- Monitor and adjust over time: Once invested, the portfolio is managed automatically through rebalancing and dividend reinvestment. You can review performance, update goals, or change contributions as your financial situation evolves.
What is a robo-advisor?
A robo-advisor is a digital investment platform that automatically builds and manages an investment portfolio on your behalf. It uses algorithms to create diversified portfolios, made up of low-cost ETFs, making it a hands-off way to approach ETF investing based on your financial goals and risk tolerance.
Robo-advisors are designed for hands-off, long-term investing rather than active trading. They charge lower fees than traditional financial advisors by automating most of the investment process.
How does a robo-advisor work?
After signing up, you complete a questionnaire covering your income, time horizon, and attitude to risk.
The platform uses this information to select an appropriate portfolio and invests your money automatically.
Your portfolio is then monitored and rebalanced over time to maintain the target allocation as markets move. Many robo-advisors also reinvest dividends and apply tax optimization strategies where available.
How much do robo-advisors cost?
Robo-advisors are low-cost compared to traditional financial advisors, but pricing models vary. Most platforms charge an annual management fee of 0.20%–0.40% of assets under management (AUM), while some use flat monthly fees, which can be cheaper for larger balances but expensive for small portfolios.
Typical robo-advisor costs
| Cost type | Typical range | What it covers |
|---|---|---|
| Management fee | 0.20%-0.40% per year | Portfolio construction, rebalancing, automation |
| Flat monthly fee | $3-$10 per month | All-in advisory access regardless of balance |
| Fund expense ratios | 0.03%-0.15% per year | Fees charged by ETF providers |
| Trading commissions | $0 | Most robo-advisors offer commission-free investing |
| Minimum investment | $0-$500 | Higher minimums may unlock premium features |
In practice, a $10,000 portfolio costs $20-$40 per year with a percentage-based robo-advisor, excluding small ETF expenses. Features such as tax-loss harvesting or access to human advisors may require higher balances or upgraded plans, which can increase total costs.
FAQs
A robo-advisor is worth it for long-term investors who want low-cost, automated portfolio management. Most charge 0.20%-0.40% annually, compared with around 1% for a traditional financial advisor.
Average long-term returns range from 5% to 8% per year before inflation, depending on risk level. Returns vary significantly year to year and are not guaranteed.
There is no single best-performing robo-advisor because performance depends on portfolio risk and market conditions. Platforms are best compared on fees, diversification, and tax efficiency, not short-term returns.
Robo-advisors generally do not outperform the S&P 500 in strong bull markets. They prioritize diversification and risk management, which can reduce volatility but also cap upside.
Most US robo-advisors are registered with the SEC and use custodians covered by SIPC insurance up to $500,000. This protects against broker failure, not market losses.
Yes, robo-advisors invest in markets, so account values can fall during downturns. Losses are possible in the short term, especially in higher-risk portfolios.
Many robo-advisors have $0-$500 minimums, making them accessible to beginners. Advanced features like tax-loss harvesting often require $25,000-$100,000.
Some robo-advisors offer tax-loss harvesting, which can improve after-tax returns by 1%-2% annually in taxable accounts. Availability depends on balance size and platform.
Yes, withdrawals from taxable accounts are available at any time with no penalties. Retirement accounts may trigger taxes or early withdrawal penalties if accessed before age 59½.
Robo-advisors are cheaper and suitable for straightforward investing needs. Human advisors may add value for complex planning, but charge three to five times more in annual fees.
Acorns is the best robo-advisor for beginners because it removes friction through automated Round-Ups and a $0 account minimum. Flat fees start at $3 per month, and portfolios use diversified ETFs with automatic rebalancing. For beginners who want more structured goal planning at scale, Betterment offers a 0.25% annual fee and diversified portfolios across 12 asset classes.
Betterment is the strongest option for retirees due to its goal-based planning tools, retirement income features, and tax-coordinated portfolios. It supports multiple IRA types and offers access to Certified Financial Planners at $100,000+ via its Premium plan. For retirees focused on minimising advisory fees, Schwab Intelligent Portfolios charges $0 management fees, with average ETF costs around 0.12%.
Fidelity Go stands out for Roth IRAs because it charges no advisory fee under $25,000, making it cost-effective for smaller retirement accounts. Portfolios use Fidelity Flex funds, which often have zero expense ratios, reducing all-in costs. Betterment is also strong for Roth IRAs due to diversified ETF portfolios and automatic rebalancing at 0.25% annually.
No robo-advisor can guarantee the “best” returns, as performance depends on asset allocation and market conditions. Over long periods, diversified ETF portfolios from providers such as Wealthfront, Betterment, and Schwab tend to track broad market benchmarks after fees. Wealthfront’s focus on daily tax-loss harvesting and optional direct indexing at $100,000+ may improve after-tax returns in taxable accounts, but outcomes vary.
Most leading robo-advisors automatically rebalance portfolios, but Betterment and Wealthfront stand out for disciplined, rules-based rebalancing aligned with target allocations. Both charge 0.25% annually and combine rebalancing with dividend reinvestment and tax optimisation tools. Schwab and Fidelity also offer automatic rebalancing, though Schwab includes a mandatory cash allocation that can affect overall performance.
Wealthfront is widely regarded as the strongest for tax efficiency due to daily tax-loss harvesting on taxable accounts and optional direct indexing at $100,000+. Its average ETF expense ratios are around 0.08%, keeping total costs competitive. Betterment also offers tax-loss harvesting and asset location features, making it a strong alternative at lower balance thresholds.
Acorns offers one of the most user-friendly mobile experiences, built around automated investing, micro-deposits, and integrated banking tools. For investors who want more detailed planning tools in-app, Betterment provides goal tracking, performance breakdowns, and tax features within a clean interface. All major US robo-advisors operate under SEC oversight and offer SIPC protection up to $500,000, but the investing app experience varies by user preference.
