1. What is the GPA Calculator?

Your GPA is the average of your grade points weighted by credit hours. Add each course with its credit hours and grade to get your semester GPA. Enter your previous CGPA and total credit hours to see your updated cumulative CGPA. The grade points follow the common 4.0 scale used by most universities, including HEC-recognised universities in Pakistan.

4. Tips for best results

Your text never leaves your device — The tool runs entirely in your browser using JavaScript. Nothing is uploaded, so you can paste private documents without worry. That also means there is no account to create and no file to upload.
It works on your phone too — Open the tool in any modern browser on Android or iPhone. The layout adjusts to the screen and everything works the same way on a small screen as on a desktop.
Read the breakdown, not just the headline number — The result updates as you type. The breakdown underneath shows how the number was worked out, which is where mistakes usually show up.
