The Equity Calculator is a user-friendly financial tool designed to simplify the process of calculating returns on equity investments. Aimed at providing convenience for investors, users can easily enter the purchase price and the quantity of their stocks to determine their profit or loss. This tool is particularly useful for both novice and experienced investors who need quick and accurate calculations.

Developed using Flask, a lightweight web framework, the Equity Calculator integrates seamlessly with the Alphavantage API. This API provides reliable and up-to-date financial data, primarily supporting stocks listed on the New York Stock Exchange (NYSE). However, one of the initial challenges in the development of this tool was finding an API that supports both NYSE and Singapore Exchange (SGX) stocks. While Alphavantage was found to be suitable for NYSE, the search for an API compatible with SGX is still ongoing.

The tool, while functional, has identified areas for improvement, particularly in the design of its user interface (UI). Future developments aim to enhance the UI to make it more visually appealing and intuitive for users, thereby improving the overall user experience. This enhancement is expected to make the Equity Calculator not only a practical tool for equity calculations but also a pleasure to use for investors globally.
