Understanding Robo-Advisors and How They Manage Investments
Robo-advisors are designed to simplify investing by automating portfolio selection, rebalancing, and other routine investment tasks. For beginners, they can provide a structured way to invest without having to manage every decision manually.
A robo-advisor is an automated investing platform that asks you a handful of questions about your goals and risk tolerance, builds a diversified portfolio of low-cost funds on your behalf, and then handles the ongoing maintenance automatically, including rebalancing, dividend reinvestment and, where offered, tax optimization.
Fees are generally lower than those of a traditional human advisor, but they vary by provider, so compare each platform's current fee schedule.

Why Robo-Advisors make Sense for New Investors
For many new investors, decision fatigue and emotional reactions do more damage than the market itself.
Morningstar's 2026 Mind the Gap study found that the average dollar invested in US funds and ETFs earned 8.7% a year over the 10 years to 2025, while the funds themselves earned 9.9% (Morningstar).
The 1.2-point gap comes from the timing and size of investors' purchases and sales, which can include panic-selling in downturns or chasing hot assets.
Robo-advisors remove most of those decisions. You answer questions once, make regular contributions, and the platform handles everything else.
There is no temptation to tinker because the interface is not designed for active trading. For people who want to build long-term wealth without spending hours researching investments, it is a practical way to start.

Five Robo-Advisors Compared
I ranked these mainly on cost for smaller balances and ease of use, using each provider's published terms.
Confirm the details on each provider's own page before you open an account, since fees, minimums and features change.
Fidelity Go
Fidelity Go is the lowest-cost fit for many beginners, so it comes first. It charges no advisory fee on balances under $25,000, uses Fidelity's own zero-expense-ratio funds, and has no account minimum, though you need $10 to start investing.
At $25,000 the fee becomes 0.35% a year on the whole balance, not just the amount above it. Fidelity's educational resources are a strength, though customer service experiences vary. For fees, minimums and account types: See Fidelity Go's page.
Schwab Intelligent Portfolios
Schwab Intelligent Portfolios charges no advisory fee, and you pay the underlying fund expenses. The trade-off is a required cash allocation, which can drag on returns, and an account minimum.
That cash allocation has been controversial. In 2022, Schwab subsidiaries agreed to pay $187 million to settle SEC charges that they hadn't disclosed how the cash holdings, which the SEC order put at 6% to 29.4% of the model portfolios, could reduce returns (SEC).
Schwab also ended its Premium tier, which added access to a certified financial planner, in early 2026, so the service is now fully automated. Fees, minimums and account types: see Schwab’s page.
Betterment
Betterment was among the first major robo-advisors and is known for its tax tools.
Its daily tax-loss harvesting, selling positions at a loss to offset gains elsewhere in your portfolio, is a feature Betterment says can add to after-tax returns for some investors.
That is a company estimate, and results depend on your tax situation and market conditions. It also offers goal-based planning, socially responsible portfolios, and a high-yield cash account.
Fees, minimums and account types: See Betterment's fee page.
Wealthfront
Wealthfront is worth comparing, particularly at larger balances. At six-figure taxable balances it offers direct indexing, which means owning individual stocks that replicate an index instead of an ETF, and that can create more tax-loss harvesting opportunities.
Fees, minimums and account types: see Wealthfront’s pricing page.
Acorns
Acorns takes a unique approach by rounding up everyday purchases and investing the spare change automatically. Spend $4.60 on coffee and $0.40 goes into your portfolio.
It sounds small, but the habit can add up. The main caveat is the flat monthly fee, which can weigh disproportionately on very small balances.
Acorns can work well as a supplement to a primary investment account. Fees, minimums and account types: See Acorns' pricing page.
Understanding Your Investment Numbers
One of the most important decisions a robo-advisor makes is how your portfolio is divided between stocks, bonds, and other investments. That allocation can have a significant effect on both the potential growth of your portfolio and the size of losses during market declines.
An aggressive portfolio generally holds a larger share of stocks and may be appropriate for investors with a long time horizon who can tolerate substantial short-term fluctuations.
A moderate portfolio typically combines stocks and bonds to balance growth potential with lower volatility. This can suit investors whose goals require growth but who also want to reduce the impact of market declines.
A conservative portfolio places greater emphasis on preserving capital and limiting volatility. It may be more appropriate for shorter investment horizons or investors who have less tolerance for significant fluctuations.
The right allocation depends on your investment horizon, financial goals, and ability to tolerate losses. A portfolio that is appropriate for one investor may be unsuitable for another.
For a deeper look at how allocation works, see our guide to building your first investment portfolio.
The Tax-Advantaged Accounts
Where you hold your investments can matter nearly as much as what you invest in. Most major robo-advisors support IRAs, but confirm that your provider offers the type you want.
A Roth IRA lets you contribute after-tax money, and earnings can be withdrawn tax-free once you are 59½ and have held a Roth IRA for five years (IRS Publication 590-B). Contribution limits change every year, so check the IRS’s current figures. For many younger investors it is a strong account to prioritize.
A Traditional IRA may give you a tax deduction now, depending on your income and whether you have a workplace plan, but you pay income tax on withdrawals in retirement. It is better suited for people expecting to be in a lower tax bracket later.
A taxable brokerage account has no contribution limits but no special tax treatment. Use it after maxing out tax-advantaged accounts.
How to Get Started
If you're just starting out, compare robo-advisors based on their fees, account minimums, investment options, tax features, and the level of human support available before choosing a platform.
If you decide to use a robo-advisor, choose a contribution amount that fits comfortably within your budget and review your account periodically rather than making decisions based on short-term market movements.
The biggest mistake most beginners make is waiting for the perfect moment or the perfect amount. Neither exists.
Conclusion
Robo-advisors have made investing accessible in a way that didn't exist a decade ago. For anyone who wants to build long-term wealth without becoming a full-time student of financial markets, they're a practical starting point.
Pick the platform that matches your balance and goals, automate your contributions, and then do the hardest part of investing: leave it alone and let it work.
