CGC (Capital Gain Calculator) is a capital‑gain visualization tool designed to automate the tax computation process for stock market trades. I built it to simplify the otherwise tedious task of manually calculating gains from AIS Trade Data downloaded from the Income Tax e‑Filing Portal.

CGC processes multiple CSV files, extracts all relevant trade details, and generates a structured Capital Gain.xlsx dashboard that makes tax planning and trade analysis far easier. With a clean, modern UI built using Flet, the tool can be compiled as a desktop app, web app, or even an Android APK, making it flexible for different use cases

UI/UX Is Important

CGC handles a lot of raw trade data, and without a clear interface, the process can quickly become overwhelming. That’s why the UI/UX became a core part of the project. The interface guides the user step‑by‑step — selecting CSV files, choosing an output folder, and generating the final dashboard — without exposing them to the complexity happening behind the scenes.

The clean layout, modern design, and simple workflow make the tool approachable even for users who aren’t familiar with spreadsheets or tax calculations. By focusing on clarity and ease of use, CGC turns a traditionally messy process into a smooth, predictable experience that anyone can follow confidently. If you want, I can also help you add a Why I Built This, Benefits, or Technical Approach section for CGC.
