Abstract: Personal financial management has become in- creasingly crucial in today’s fast-paced world where individuals struggle to track their expenses manually. This research paper presents the design, development, and implementation of a comprehensive Expense Tracker web application built using the MERN (MongoDB, Express.js, React, Node.js) stack. The application provides users with an intuitive platform to monitor income and expenses, categorize transactions, set monthly budgets, and analyze spending patterns through interactive visualizations. Key features include JWT-based authentication, dynamic transaction filtering, category management, budget tracking with proactive alerts, and data visualization. The paper discusses the technology selection rationale, system architec- ture, implementation challenges, and performance evaluation. The application demonstrates how modern web technologies can be leveraged to create effective financial management tools that empower users to make informed financial decisions.
