This study examines the complex relationship between digital financial inclusion and broader sustainable development objectives, particularly within low-income sectors. Through a comprehensive methodology incorporating systematic literature review, theoretical frameworks, and both quantitative and qualitative analyses, the research investigates how financial inclusion correlates with poverty alleviation, economic growth, and social development. The study employs a structured questionnaire methodology with 134 respondents and utilizes statistical tools including correlation analysis, regression analysis, and Partial Least Square Structural Equation Modeling (PLS-SEM). Findings reveal significant positive correlations between financial inclusion initiatives and sustainable development outcomes, with behavioral intention, social influence, and usability emerging as key determinants. The research demonstrates that participation in the financial system stimulates business creation, employment opportunities, and economic growth while reducing income disparities. Additionally, it examines financial inclusion’s influence on enhancing investment knowledge and other critical Sustainable Development Goals (SDGs) components. These insights prove valuable for policymakers, financial institutions, and development professionals working to create more inclusive and sustainable financial systems.
