Abstract

The Personal Expense Tracker with Currency Converter is a web-based application designed to assist users in efficiently managing and monitoring their daily financial activities. The system enables users to record, categorize, and analyse income and expenses through a simple and user-friendly interface while maintaining a digital log of all transactions. It provides analytical insights using summaries and visual representations to help users understand their spending behaviour. A significant feature of the proposed system is the integrated currency converter, which allows real-time conversion of expenses into multiple currencies using updated exchange rates, making it particularly useful for users handling international transactions or travel-related expenses. The primary objective of this project is to enhance personal financial management, promote savings awareness, and simplify expense tracking through automation. The application is implemented using web technologies such as HTML, CSS, JavaScript, and a backend language like Python for data handling and processing, thereby offering an efficient and practical solution for modern personal finance management.
