How do Robo-Advisors Work and Are They Effective?
A robo-advisor (sometimes written as roboadvisor) is an online platform that helps you manage your money and investments automatically—no financial advisor required. It asks you a few questions about your goals and financial situation, usually through a quick survey. Then, using smart algorithms, it gives you personalized advice and handles your investments for you.
You might also hear robo-advisors called things like automated investment advisors, digital advice platforms, or automated portfolio managers.
The best robo-advisors are easy to use, offer strong financial planning tools, low fees, and extra features like educational content, customer support, and strong security.
A Quick Look at the History
Robo-advisors really started to gain traction in 2008 when Betterment and Wealthfront launched. Wealthfront originally focused on mutual funds for the tech crowd, while Betterment aimed to make managing investments easier with online tools.
While the technology behind robo-advisors isn’t exactly new—human advisors have used similar software since the early 2000s—it was only available to professionals back then. These new platforms opened the door for everyday investors.
Most robo-advisors use passive investing strategies based on modern portfolio theory (MPT). This means they focus on building long-term, diversified portfolios instead of picking individual stocks.
How Robo-Advisors Work
Once you open an account, the robo-advisor builds a portfolio using ETFs (exchange-traded funds) or mutual funds. You typically don’t pick the investments yourself. Instead, the platform does everything based on your goals and risk level.
Some robo-advisors offer specialized portfolios like:
- Socially responsible investing (SRI)
- Halal investing
- Tactical strategies that mimic hedge funds
Many also provide advanced features like tax-loss harvesting, automatic rebalancing, and retirement planning.

Automatic Rebalancing
After your portfolio is created, it needs to be maintained. Robo-advisors handle this automatically through a process called rebalancing.
What’s Rebalancing?
Let’s say your ideal portfolio is:
- 30% emerging market stocks
- 30% U.S. blue-chip stocks
- 40% government bonds
You give each asset a target percentage with a small flexibility range, say ±5%. If market changes push your holdings outside that range, the robo-advisor will automatically buy or sell to get everything back in balance.
Tax-Loss Harvesting
Some robo-advisors also use a strategy called tax-loss harvesting to help reduce your taxes.
Here’s how it works:
If an ETF you own loses value, the robo-advisor might sell it to “lock in” the loss (which offsets your capital gains tax). Then, it buys a similar (but not identical) ETF to keep your portfolio on track.
These platforms follow IRS rules, like the wash-sale rule, which says you can’t buy back a “substantially identical” investment within 30 days of selling it.
Why People Like Robo-Advisors
Robo-advisors are growing fast—and for good reason. Here’s why so many people are using them:
✅ Pros:
- Low Cost: Fees are often under 0.4%, much lower than the 1% most human advisors charge.
- Easy to Start: You can often get started with as little as $0 to $500.
- 24/7 Access: You can log in and check your investments any time.
- Simple Setup: Most platforms walk you through a quick survey and do the rest.
- Good for Beginners: You don’t need to know much about investing.
- No Emotional Decisions: Algorithms stay consistent even when markets are crazy.
What Robo-Advisors Can’t Do
They’re great for many people, but robo-advisors aren’t perfect.
❌ Cons:
- No Human Touch: They won’t offer emotional support or personalized advice during tough times.
- Not Great for Complex Needs: Estate planning, tax strategy, and trust management usually require a real advisor.
- One-Size-Fits-All: You’ll need to clearly understand your goals, which not everyone does.
- Not Ideal During Market Crashes: Many users feel uneasy without a human to talk to during downturns.
A study by Investopedia found that about 40% of users wouldn’t feel comfortable using only a robo-advisor during major market volatility.

Choosing the Right Robo-Advisor
Not all robo-advisors are the same. Some focus on beginner investors, while others are built for experienced users. Before choosing one, compare features like:
- Fees
- Minimum investment requirements
- Available tools and customer service
- Portfolio customization options
You’ll usually start by answering a few questions about your finances and linking your bank account to fund your account.
Who Uses Robo-Advisors?
They’re especially popular among Millennials and Gen Z—people who are tech-savvy, comfortable sharing info online, and just starting to grow their wealth.
Most robo-advisors reach out to these users through social media and mobile-friendly platforms.
Are Robo-Advisors Regulated?
Yes, robo-advisors must follow the same rules as human advisors. They’re registered with the SEC and many are members of FINRA. You can even look them up on BrokerCheck just like a regular advisor.
Keep in mind: your investments aren’t FDIC-insured because they’re not held as cash in a bank. However, most robo-advisors are covered by SIPC, which protects up to $500,000 if the company fails.
How Do Robo-Advisors Make Money?
Most robo-advisors charge a flat percentage based on how much money they manage for you—usually around 0.25–0.40% per year.
They may also earn money by:
- Payment for order flow: Earning tiny fees for sending trade orders to certain partners
- Partner offers: Promoting mortgages, credit cards, or insurance products to users

Final Thoughts
Robo-advisors are changing the way people invest. They make financial planning simple, affordable, and accessible—even if you’re just starting out.
But they’re not for everyone. If you need complex advice or prefer talking to someone face-to-face, a traditional advisor may be better. Still, for many, a robo-advisor is a smart, low-stress way to grow your money.
