Financial Inclusion refers to the accessibility of economic entities to affordable and essential financial products and services, which meets their financial needs. This paper aims to find the factors contributing to FI of the women slum dwellers in Kolkata, through PMJDY, the factors contributing to influence these women slum dwellers in Kolkata, to have a bank account, and the impact of FI on the financial aspects of women slum dwellers, representing a very vulnerable section of the population. To achieve these objectives, it has used a structured questionnaire to collect primary data from the women slum dwellers of Kolkata. The stratified random sampling method was used. It has analysed the data in SPSS using techniques of logistic regression, descriptive statistics, etc. as is relevant. The findings shows that the PMJDY scheme has provided banking access to such deprived sections, has profound effect on their financial habits, gave access to several other governmental schemes, through their identification of the bank accounts, etc. It has particularly benefitted the women section, by mobilising their savings into channels of investment for their future. This has been a massive overcome from their habits of hoarding money, which ultimately finds its way to necessary or unnecessary consumptions, leaving them in financial stress. Thus, the findings have proved to some extent the beneficiary-centric theories of Financial Inclusion. It does find that FI benefits the financially deprived sections, by aligning them with the mainstream. It has impressed upon the idea of empowering the vulnerable sections in general and the women in these groups in particular, towards achievement of the SDG goals. It suggests the enhanced role of private–public partnership (PPP) in achieving a better result in these initiatives, through the Corporate Social Responsibility (CSR) policy involvement.
