The primary difference between GPA and CGPA is the scope of calculation. GPA (Grade Point Average) measures a student's performance in a single semester or term, whereas CGPA (Cumulative Grade Point Average) measures their cumulative performance across the entire duration of their degree program.
Comparison Table
| Feature | GPA (Grade Point Average) | CGPA (Cumulative Grade Point Average) |
|---|---|---|
| Scope | Single term, semester, or academic block. | Entire academic program (all semesters). |
| Formula Basis | Credits and grades earned in one semester. | Weighted sum of all grades and credits across all terms. |
| Frequency | Calculated at the end of each semester. | Updated cumulatively as semesters progress. |
| Key Utility | Used to assess term progress or check immediate performance. | Used by recruiters, admissions boards, and graduation panels. |
How They Relate Mathematically
Your CGPA is essentially the credit-weighted average of all your semester GPAs. If you have semesters of varying credit loads, you cannot calculate CGPA by simply adding your GPAs and dividing by the number of semesters.
To find CGPA from GPA values:
CGPA = Σ (Semester GPA × Semester Credits) / Total Program Credits
