The past decade has seen a growing awareness of the importance of individual financial well-being. This note presents a consensual concept of financial well-being, including a preliminary conceptual framework and a working definition, as well as a preliminary roadmap for developing a measurement framework. The note aims to help identify financial sector policies and other factors that can positively affect financial well-being, recognising the role of broader economic and social factors. The note was developed for the G20 Global Partnership on Financial Inclusion (GPFI) jointly by Brazil’s 2024 G20 Presidency and the OECD, with contributions from the Consultative Group to Assist the Poor (CGAP) and the Office of the United Nations Secretary-General’s Special Advocate for Financial Health (UNSGSA).
