Clear Wealth: An Intelligent, Client-Side Personal Finance and Investment Management System

Personal financial management has evolved from simple expense tracking into comprehensive wealth management requiring strategic budgeting, investment forecasting, and behavioral analysis. This paper introduces "ClearWealth," a holistic, browser-based personal finance application designed to address these multifaceted needs. Unlike traditional backend-heavy trackers, ClearWealth operates as a highly responsive client-side application utilizing HTML5, CSS3, and JavaScript, augmented by Chart.js for data visualization and html2pdf.js for automated reporting. The system integrates secure local authentication for multi-user data segregation, a dynamic 50-30-20 budget tracking algorithm, Systematic Investment Plan (SIP) and Lumpsum calculators, goal-oriented savings trackers, and an AI-driven advisory module that analyzes localized financial states. This study details the architectural framework, mathematical models governing the investment calculators, and the user-interface design principles that drive financial mindfulness. Experimental deployment demonstrates that integrating real-time visual feedback with embedded investment planning significantly enhances user engagement and financial literacy.
