What is a robo-advisor? A beginner's guide
Financial basics · March 25, 2026Lydia Makin
Investing used to require time, expertise, and often a financial advisor. Robo-advisors have changed that by automating many of the decisions involved in managing investments.
In this guide, we explain what a robo-advisor is, introduce our own, and dive into how it works and whether it might be a good option for you as a beginner investor.

What is a robo-advisor?
A robo-advisor is a digital platform that provides automated, algorithm-driven financial planning and investment services with minimal human intervention. Essentially, it's a software-based service that manages your investment portfolio for you.
The robo-advisor definition centers on the idea of removing the manual effort of picking individual stocks or bonds. Instead of you deciding what to buy and when to sell, the software handles these decisions for you, based on your specific financial goals and risk tolerance. These platforms are often called automated investing platforms or digital advice services.
Traditional wealth management was once reserved for those with significant amounts of money. Now, robo-advisors have made professional-grade investment strategies accessible to almost anyone. By using technology to replace human labor, these platforms can offer services at a lower cost than a traditional human advisor.
How a robo-advisor works
The process of using a robo-advisor is designed to be simple for the customer. It typically begins with a digital interface rather than a face-to-face meeting.
The suitability assessment
When you join a robo-advisor platform, you usually complete an online questionnaire. This survey asks about your financial situation, your investment experience, and what you hope to achieve. Most importantly, it gauges your risk tolerance.
Because everyone has a different comfort level with market fluctuations, the algorithm needs to know if you prefer a conservative approach (protecting your money) or a more aggressive one (seeking higher growth despite higher risk). Once the software has this information, it builds a diversified portfolio tailored to your profile.
The role of algorithms and modern portfolio theory
Most automated investing platforms rely on a concept called Modern Portfolio Theory (MPT). This is a mathematical framework for assembling a portfolio of assets to maximize the expected return for a given level of risk.
Instead of trying to 'beat the market' by picking the next big tech stock, robo-advisors often use passive indexing strategies. This means they invest in exchange-traded funds (ETFs) that track the performance of a specific market index, such as the S&P 500. This approach helps to spread risk across hundreds or thousands of different companies and asset classes.
Automatic portfolio rebalancing
Markets move constantly. Over time, some of your investments might perform better than others, causing your portfolio to drift away from its original target. For example, if your stocks perform very well, they might end up representing 70% of your portfolio, instead of your target 60%.
Robo-advisors monitor this drift. When the weighting of an asset class moves outside of a certain range, the algorithm automatically sells some of the over-performing assets and buys more of the under-performing ones. This process, known as rebalancing, ensures your risk level stays consistent without you needing to lift a finger.
Robo-advisor vs financial advisor: What's the difference?
Deciding between a robo-advisor vs financial advisor often comes down to how complex your needs are and how much personal interaction you want.
Feature | Revolut Robo-advisor | Financial advisor |
Cost | $0.25 per month on balances above $100, or 0.25% of assets under management per year, whichever is higher | Often 1% or more annually |
Accessibility | Available 24/7 via app or web | Requires scheduled appointments |
Minimum balance | $100 | Often high |
Personalisation | Algorithm, based on your inputs | Tailored to complex life events |
Complexity | Best for standard investing | Better for estate planning and taxes |
While human wealth managers can provide empathy and help with complex issues like inheritance tax or estate planning, they are more expensive. Robo-advisors are useful if you want a straightforward, low-cost way to grow your money over the long term.
The advantages of automated investing platforms
For many people, the shift towards digital advice is driven by 3 main benefits: accessibility, efficiency, and strategy.
Accessibility and lower entry barriers
In the past, many investment firms would not work with customers unless they had a minimum of $50,000 to invest. Robo-advisors have removed this barrier. Many automated investing platforms allow you to start with very small amounts, making it easier for beginners to enter the market.
Efficiency and time management
Managing a portfolio manually requires hours of research and execution. You would need to monitor news, understand financial statements, and execute trades during market hours. A robo-advisor does all of this for you. Once you've set your goals and added money, the system works in the background, allowing you to focus on other priorities.
Consistency in strategy
Human beings are prone to emotional decision-making. When markets fall, many investors panic and sell at a loss. When markets rise, they might buy in too late due to a fear of missing out. An algorithm doesn't have these emotions. It follows the data and stays detached, which can lead to more discipline and better long-term results.
Important considerations and risks
No investment is without risk, and robo-advisors are no exception. It's important to remember that when you invest, your capital is at risk. The value of your investments can go down as well as up, and you may get back less than you originally put in.
Automated platforms are also not a perfect solution for everyone. Because they're driven by code, they can't account for sudden changes in your personal life that you haven't entered into the system. If you lose your job or have an unexpected medical expense, the robo-advisor won't know unless you update your profile or change your contribution settings.
Most robo-advisors offer a limited range of investment options. You generally can't choose specific stocks or bonds to include in your automated portfolio. If you want to have total control over every single asset, you might prefer stock trading where you make the decisions yourself.
Regulation and security of your money
In the US, robo-advisors are subject to the same strict regulations as traditional brokerage firms and financial advisors.
While the value of your investments isn't protected against market losses, your assets are often protected against the failure of the firm itself. It's always important to check the specific protections offered by any platform you choose.
