<p>In the emerging intricacies of the working class constantly striving for money and contentment balance, the concept of financial satisfaction has garnered much attention. Using human capital theory and theory of planned behavior, the study aims to assess the impact of financial literacy (FL) on employees’ financial satisfaction (FS) and the mediating role of financial behavior (FB) and financial attitude (FA) in this relationship in the context of the human capital of the Indian IT sector. This study employed PLS-SEM to examine the links between dependent, independent, and mediating variables, based on responses from 251 IT sector employees in the West Bengal regions collected through structured questionnaires. The findings revealed that FL had a significant direct and indirect impact on employees’ FS. Concomitantly, FB and FA have significant complementary partial mediating roles in the FL-FS relationship. Considering the available mainstream contemporary literature, to the best of the authors’ knowledge, this research model has not previously been investigated; hence, this study is a pioneer providing implications for both organizations and policymakers; advancing a novel dual-mediation model within the framework of human capital theory and theory of planned behavior. Further, the study findings guide IT firms to inculcate financial well-being through targeted literacy, attitude, and behavior interventions.</p>
