In order to provide practitioners and researchers with a standard, reliable, and broadly available way to measure individual financial well-being, the CFPB led a rigorous research effort to develop a consumer-driven definition of financial well-being, and then tested a set of questions–a “scale”–to measure financial well-being. The scale is designed to allow practitioners and researchers to accurately and consistently quantify, and therefore observe, something that is not directly observable–the extent to which someone’s financial situation and the financial capability that they have developed provide them with security and freedom of choice. This guide describes the research behind the CFPB Financial Well-Being Scale and provides detailed steps for using it, including how to score individuals’ responses and compare their scores.
