How We Review Robo-Advisors (2024)

Investopedia’s list of the best robo-advisors is based on in-depth research and robust data across 21 companies that offer digital investment services. We reviewed each company’s account services, investment options, customizable portfolio management features, cash management tools, fees, and much more. This guide explains the categories and criteria we used to evaluate each company’s offerings and our scoring process for determining the best robo-advisors.

Our editors and researchers independently evaluate all recommended products and services. If you click on links we provide, we may receive compensation.

How We Research Robo-Advisors

Through a combination of subject matter expertise, consumer survey and company survey data, and industry research, we developed a quantitative model that scores each company based on nine major categories and 59 criteria that are crucial in evaluating the advisors’ offerings and usability.

To collect the data, we sent a digital survey with 64 questions to each of the 21 companies we included in our rubric. Additionally, our team of researchers verified the survey responses and collected any missing data points through online research and conversations with each company directly. The data collection process spanned from Jan. 8, to Feb. 9, 2024.

In 2023, our research team conducted a survey of 205 U.S. adults aged 18 to 72 who are current clients of one of 18 robo-advisors that are part of our rubric. Participants in this 2023 survey opted-in to an online, self-administered questionnaire from a market research vendor. Survey data collection took place between Aug. 30, and Sept. 15, 2023, with 11 video interviews conducted with volunteer respondents from Sept. 7, to Sept. 17, 2023. Multiple quality checks, including screeners, attention gauges, comprehension evaluations, and logic metrics, among others, were used to ensure only the highest quality responses were included.

This 2023 survey was used to inform our weighting and scoring process for our 2024 best robo-advisor awards to best serve readers’ needs. We adjusted the weights for goal planning, fees, portfolio contents, portfolio management, and user experience because our survey told us that those factors matter more and less to readers looking for a robo-advisor.Investors are likely to use robo-advisor platforms to invest for goals like large purchases—houses, vehicles, and travel—more than retirement. The majority of investors who use these platforms are in their 20s and 30s, and consider themselves to have intermediate-to-advanced computer skills. Fee-based financial planning tools and services is the most searched topic by robo-advisor users.

Robo-Advisor Evaluation Categories

Based on a combination of subject matter expertise and the results of our 2023 Robo-Advisor Consumer Survey, we developed the following category weights:

These categories were then broken down into 59 weighted criteria, resulting in 1,239 data points that make up our scoring rubric.

Through this all-encompassing data collection and review process, Investopedia has provided you with an unbiased and thorough review of the top robo-advisors.

Data Collection and Scoring

• Data points are scored on a 0.00 - 1.00 scale
• Binary criteria = [0,1]
• Scaled criteria (e.g., 5-point) = [0.00, 0.25, 0.50, 0.75, 1.00]
• Continuous criteria, minimum value in the database was re-scaled to 0.00 and maximum value was re-scaled to 1.00
  

Goal Planning

Investors have diverse sets of goals and timelines that extend well beyond simply saving for retirement. That's why having access to tools that help you build the capital needed to make large purchases is also a top considerations when choosing a robo-advisor.

This entire section accounts for 21% of the total weighted score in our evaluation.

To evaluate goal planning, we looked to see if the following tools and features were available to clients:

Retirement Planning Tools

We score this on a binary scale, awarding 1 point to companies offering retirement planning tools, and 0 points to those that lacked these tools.

Planning Tools for Large Purchases

We score this on a binary scale. If the robo-advisor offers planning tools for large purchases, a score of 1 was given. For companies lacking these tools, a score of 0 was given.

Other Goal Tools

For this criteria, we scaled the responses (0.00, 0.25, 0.50, 0.75, 1.00) and awarded companies with the largest selection of goal-planning tools outside of retirement and large purchases the highest scores. Conversely, companies with more limited goal-planning tools received the lowest scores.

Portfolio Management

The quality and availability of portfolio management features is critical when choosing a robo-advisor. It’s essential to know how portfolios are managed and the features available to clients to monitor their portfolios. This entire section accounts for 17% of the total weighted score in our evaluation.

To evaluate portfolio management, we looked at the following features:

Automatic Rebalancing

We scored this item on a continuous scale of 0.00 to 1.00, as opposed to a binary scale.

Portfolio Contents

The asset management industry is always evolving and new investment vehicles that improve tax efficiency, provide access to new asset classes, and address socially sensitive concerns are constantly being introduced. The best robo-advisors quickly incorporate these features and maintain a wide range of non-proprietary investment types that help lower the barrier to entry, suppress fees, and broaden allocation options.

This entire section accounts for 17% of the total weighted score in our evaluation.

To evaluate portfolio contents, we looked to see if the following asset classes were available to clients:

Socially Responsible Investing (SRI) or Environment, Social, and Governance (ESG) Options

Robo-advisors that provide SRI or ESG investments were given a binary score of 1, while a 0 was given if these options are not available.

Fees

Because many of these digital wealth management platforms invest client assets in prepackaged portfolios and involve minimal human supervision, they are able to charge lower fees than traditional financial advisors. But there are also a number of robo-advisors that provide more customized products and access to licensed representatives, which may result in higher fees.

This entire section accounts for 15% of the total weighted score in our evaluation.

When analyzing the costs associated with using a robo-advisor’s platform and services, we looked at the following criteria:

Fees and Commissions Charged for Trading Individual Stocks

We used a scaled criteria model (0.00, 0.25, 0.50, 0.75, 1.00) and gave the highest scores to companies with the lowest average underlying fee for ETFs. Conversely, companies with the highest average underlying fee were given the lowest scores.

User Experience

At their core, robo-advisors are digital wealth management platforms, which means human assistance is often limited during the onboarding process. Therefore, the best robo-advisors provide a smooth user journey and easy-to-use features that make investing enjoyable for less experienced investors.

This entire section accounts for 5% of the total weighted score in our evaluation.

To evaluate each platform’s user experience, we looked at the following features:

Usability

We scored this item on a continuous scale of 0.00 to 1.00, as opposed to a binary scale. Our subject matter expert tested the usability of each platform and gave companies with the best user experience a high score. Conversely, platforms that offer a weak user experience were given lower scores.

Security and Education

Although robo-advisors are designed so that you only need minimal involvement in the money management process beyond the initial onboarding survey, the best robo-advisors provide useful prompts and other forms of educational content to help guide you along your journey.

In addition, most robo-advisors offer two-factor authentication and encrypted security measures. However, there are meaningful differences in the level of SIPC insurance available to insure your money against institutional failure.

This entire section accounts for 5% of the total weighted score in our evaluation.
