Workplace financial interventions are increasingly being implemented to mitigate employee financial stress and enhance financial behavior. However, the evidence regarding their comparative effectiveness, gender responsiveness, and applicability to emerging economies remains fragmented. This systematic review seeks to identify and assess the effectiveness of financial interventions implemented within the workplace, with a particular focus on the design of interventions, delivery mechanisms, and gender-specific reporting. In accordance with PRISMA guidelines, comprehensive searches were conducted across major academic databases and institutional sources for studies published between 2000 and 2024. A total of nineteen empirical studies on workplace interventions met the inclusion criteria, covering default-based interventions, financial education, financial coaching, and digital financial wellness programs. The results demonstrate that default-based payroll interventions consistently lead to the most significant and enduring improvements in saving behaviors, while educational and digital programs show varied behavioral outcomes. Financial coaching is effective for participants who are highly engaged, though its reach is limited. Nonetheless, there is a scarcity of gender-disaggregated outcomes and evidence from India. This review offers an evidence-based framework to assist employers, HR teams, and policymakers in crafting more effective and inclusive workplace financial programs, while also identifying critical areas for future research
