In this study we examined the construct of financial wellness and its relationship to personal wellbeing, with a focus on the role of financial literacy. We made gender comparisons using a structural equation modeling analysis with variables that measured personal wellbeing, financial satisfaction, financial status, financial behavior, financial attitude, and financial knowledge. The research indicates that males ranked higher in financial satisfaction and financial knowledge than females; on the other hand, females ranked higher in personal wellbeing than males. The model of financial wellness proposed by Joo (2008) was operationalized to examine three alternative structural models. The model that best fitted the data was the one where financial wellness was conceived as a set of relations between variables. The relationship of all the variables to personal wellbeing was mediated by financial satisfaction, with some gender differences: In females the main source of financial satisfaction was financial status; in males it was financial knowledge.
