Methodology

NerdWallet's ratings for brokers and robo-advisors are weighted averages of several categories, including investment selection, customer support, account fees, account minimum, trading costs and more. Our survey of brokers and robo-advisors includes the largest U.S. providers by assets under management, plus notable and/or emerging players in the industry. Factors we consider, depending on the category, include advisory fees, branch access, user-facing technology, customer service and mobile features. The stars represent ratings from poor (one star) to excellent (five stars). Ratings are rounded to the nearest half-star.
