This study explores the critical relationship between Digital Financial Literacy (DFL) and Digital Financial Inclusion (DFI) among salaried individuals in the Delhi NCR region, with a particular emphasis on the influence of family and social networks. Despite increased availability of digital financial services such as mobile banking, e-wallets, and online investment platforms, disparities persist in their adoption and usage, largely due to gaps in digital financial literacy. Based on a structured survey of 399 salaried respondents, the research identifies a strong positive correlation between DFL and DFI, establishing that higher digital financial literacy leads to greater inclusion, more informed financial decision-making, and improved personal financial management. The findings suggest that social and familial influences play a pivotal role in empowering individuals to navigate digital finance confidently and securely. Older and more educated individuals are shown to be more digitally financially literate and inclusive, underscoring the need for targeted interventions aimed at younger and less-educated segments. Integrating a sustainability perspective, this study highlights how promoting digital financial literacy fosters economic resilience, social equity, and sustainable financial empowerment, which are crucial for reducing inequalities and supporting enduring digital financial ecosystems. The research underscores that sustainable digital inclusion requires not only technological access but also ongoing education and community engagement to ensure long-term financial well-being and environmental consciousness in economic behaviors. The study advocates digital financial literacy as a key enabler of sustainable development, aligned with global sustainability goals.
