The primary objective of this study is to investigate the impact of financial literacy on consumer financial behavior through a systematic literature review. While numerous studies have explored this association, there is a lack of a comprehensive analysis that consolidates diverse insights and offers a holistic view. Our study addresses research questions, including the utilization of theoretical frameworks explaining the impact of financial literacy on consumer financial behavior. Also, we explore the diverse contexts encompassing industries, countries, and consumer types, involved in this relationship. We scrutinize the dependent, independent, control, mediating, and moderating variables involved, along with the methodological approaches utilized for assessing the impact. Employing the Theory, Context, Characteristics, and Methodology (TCCM) framework, we systematically analyzed 79 identified papers using the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR‐4‐SLR) protocol. The findings highlight the multifaceted factors shaping individuals' financial decisions and behaviors, shedding light on the complex dynamics prevalent across industries, countries, and consumer segments. Our review offers insights into future research directions, advocating the integration of fresh theories and innovative methodologies to enhance existing knowledge. This study significantly contributes to academic understanding and offers valuable guidance for policymakers, businesses, and educators seeking to enhance financial literacy education and shape positive consumer financial behaviors.
