CGPA Calculator
Convert semester GPAs into a cumulative GPA and an approximate percentage.
Inputs
Formula
- CGPA = Σ(GPA × credits) / Σ(credits)
- Percentage ≈ CGPA × 9.5 (10-point scale)
A cumulative GPA is credit-weighted, so a heavy semester counts more than a light one. The percentage conversion uses the common ×9.5 rule that most Indian universities publish — check your own institution's table before quoting it.
