An RIA’s margin is a simple, easily observable figure that encompasses a range of underlying considerations about a firm that are more difficult to measure, resulting in a convenient shorthand for how well the firm is doing. Does a firm have the right people in the right roles? Is the firm charging enough for the services it is providing? Does the firm have enough–but not too much—overhead for its size? The answers to all of these questions (and more) are condensed into the firm’s margin.
