Profitability

🎯 About the Project

This repository contains the frontend source code of a web application developed as part of a higher education Capstone Project (Projeto Integrador). The tool is dedicated to calculating and analyzing the net profitability of fixed-income investments, combining concepts from economics, finance, and computer science to support financial literacy and education.

The application communicates with a robust API developed in TypeScript (backend), responsible for logical and financial processing. For details regarding the server architecture, please refer to the API repository.

Implementation Note: In this academic version, the backend URL is statically configured (hardcoded) to point directly to the API instance at https://github.com/EconObs/profitability-api-ts.

🛠️ Architecture and Features

• Profitability Calculator: An interactive interface developed to simulate and compare the net yield of various fixed-income investments.
• Real-Time Data Integration: Dynamic retrieval of official economic indices directly through the Central Bank of Brazil (BCB) API.
• Methodological Approaches: The project includes different calculation approaches, whose compiled versions and development histories can be found in the Releases section.
