What Is CGPA?
CGPA (Cumulative Grade Point Average) is a numerical measure of a student’s overall academic performance across all semesters.
It represents the average of all GPA values earned in different semesters, weighted by credit hours.
CGPA is commonly used in:
- Universities and colleges
- Scholarship evaluations
- Job applications
- Academic transcripts
- International admissions
- Performance assessments
CGPA is different from GPA, because GPA is calculated for a single semester, while CGPA covers your entire academic journey.
How the Discussiony CGPA Calculator Works
The calculator automatically:
- Multiplies each subject’s credit hours × grade points
- Adds all total grade points
- Divides them by total credit hours
- Instantly shows the final CGPA
You don’t need to remember any formula or perform manual calculations — the tool does everything for you.
CGPA Formula
CGPA = (Total Grade Points Earned) ÷ (Total Credit Hours)
Example:
If your total grade points are 152 and total credit hours are 44, then:
CGPA = 152 ÷ 44 = 3.45
GPA vs CGPA — What’s the Difference?
GPA shows your performance in one semester.
CGPA shows your performance in all semesters combined.
| Category | GPA | CGPA |
|---|---|---|
| Coverage | One semester | Entire academic duration |
| Use | Short-term performance | Final academic evaluation |
| Impact | Semester grades | Degree completion, jobs, scholarships |
Both are important, but CGPA carries more weight in official records.
CGPA to Percentage Conversion
Many institutions require percentage instead of CGPA. The most commonly used formula is:
Percentage = CGPA × 9.5
Example
If your CGPA is 8.2:
8.2 × 9.5 = 77.9%
SGPA to CGPA Conversion
If you only have SGPA (Semester GPA) for each semester, CGPA is calculated using:
CGPA = (SGPA1 + SGPA2 + SGPA3 + … + SGPAn) ÷ Total Semesters
Example:
If your SGPAs are: 8.1, 7.9, 8.5, 8.2
Then:
CGPA = (8.1 + 7.9 + 8.5 + 8.2) ÷ 4 = 8.175
Why CGPA Calculation Can Be Confusing
Students often get confused because:
- Different universities follow different grading scales
- Some use credit hours, some do not
- Some use 4.0 scale, others use 10.0 or 5.0
- Grade points for A, B, C vary by institution
- Weighted vs non-weighted systems differ
The Discussiony CGPA Calculator solves all these issues by providing an instant error-free calculation.

How to Calculate CGPA Manually (Step-by-Step)

3. Multiply:
Grade Point × Credit Hours
4. Add all subject totals
5. Add all credit hours
6. Apply the formula:
CGPA = Total Grade Points ÷ Total Credit Hours
