The present study titled “Financial Anxiety and Spending Behaviour among Gen Z” aims to analyse the level of financial anxiety experienced by Generation Z and to examine its impact on their spending behaviour.The main objectives of the study are to understand the concept of financial anxiety, identify the major factors contributing to financial stress among Gen Z, analyse their spending behaviour patterns, and examine the relationship between financial anxiety and financial decision-making. The research is based on primary data collected through a structured questionnaire from selected Gen Z students and young adults. Secondary data were collected from books, journals, research articles, and reliable online sources. The collected data were analysed using Percentage Analysis and Weighted Average Method. The study concludes that improving financial literacy, encouraging disciplined budgeting methods like the 50–20–30 rule, and promoting responsible spending habits can help reduce financial anxiety and improve long-term financial security among Gen Z.
