How CGPA Is Calculated

CGPA = (Sum of [Grade Point × Credit Hours] for all subjects) ÷ (Total Credit Hours). Each subject's contribution is weighted by how many credit hours it's worth, so a 4-credit course affects your CGPA more than a 1-credit course.

Common Use Cases

• Tracking your cumulative academic performance across semesters.
• Estimating your final CGPA before results are officially published.
• Converting your CGPA to a percentage for job or scholarship applications.
• Planning what grades you need in remaining subjects to reach a target CGPA.

Privacy & Security

All calculations happen locally in your browser. Your subject list is optionally saved in your browser's local storage for convenience and is never uploaded to any server.
