This study examines the relationship between mathematical confidence and financial literacy, exploring how both independently and interactively influence financial behaviors. Utilizing data from the 2021 National Financial Capability Study, the research investigates if confidence in mathematics complements financial knowledge in predicting positive financial actions, such as saving, emergency fund management, and retirement planning. Findings indicate that mathematical confidence is significantly associated with specific financial behaviors, including retirement contributions and planning, and that the interaction between mathematical confidence and financial literacy correlates with emergency fund ownership. The study underscores the potential of incorporating mathematical competence into financial education efforts to enhance financial well-being and suggests future research directions for understanding the nuanced roles of math skills in financial decision-making.
