Ratings Methodology for Robo-Advisors
NerdWallet’s overall ratings for robo-advisors are weighted averages of ratings in the following larger categories:
Types of accounts supported.
Customer support options.
Human advisor option.
Data collection and review processNerdWallet currently reviews 18 robo-advisors that together constitute the majority of the robo-advisor market based on their assets under management.
We collect data from providers and observe provider demonstrations as necessary. Our process starts by sending detailed questionnaires to providers. The questionnaires are structured to equally elicit both favorable and unfavorable responses. They are not designed or prepared to produce any predetermined results. The questionnaire answers, combined with product demonstrations, interviews of provider personnel and hands-on research by our specialists, make up our proprietary assessment process that scores each provider’s performance across more than 20 factors.
The final output produces star ratings from poor (1 star) to excellent (5 stars). Ratings are rounded to the nearest half-star.
Our writers and editors conduct robo-advisor reviews on an annual basis. Throughout the year, we maintain contact with providers and update any changes to their offerings.
Factor weightingsThe weighting of each rating factor is based on our team’s assessment of which features are most important to consumers and which ones impact the consumer experience in the most meaningful way. Those factors vary depending on the category.

Account minimumWe consider the minimum dollar amount (if any) required to open an account. A $0 account minimum earns the highest rating, and an account minimum of $25,000 or higher earns the lowest rating.
Account feesThis category takes into account the following from each provider:
Portfolio mixWe consider:
Accounts supportedWe consider the number and type of accounts the provider is able to manage, including:
Providers that offer all of the above options, or that manage accounts held by outside custodians, earn the highest rating. Those that offer only an IRA or a taxable account earn the lowest rating.
Customer supportWe rate customer support on two factors: Phone support and website usability. If a provider offers 24/7 phone support, it earns the highest rating. If it offers no support by phone, email or chat, it earns the lowest rating. We define website usability as how easy it is for our reviewers to find key details on the site. If we can find all information in under five minutes, a provider earns the highest rating. If we can’t find any information, the provider earns the lowest rating.
Automated servicesThis takes into account whether a provider offers:
Human advisor optionWe consider whether robo-advisors offer financial planning advice from a licensed professional, whether that advice carries an additional fee, how accessible those professionals are, and what licenses they carry. If a provider offers unlimited access to CFPs, it earns the highest rating. If it offers no human advisor option, it earns the lowest rating.
