Calculate Overall CGPA of All Semesters (Multi-Scale Guide)
Cumulative Grade Point Average (CGPA) is an essential academic metric that reflects your overall performance across multiple semesters. Whether you are a high school, college, or university student, understanding how to calculate your CGPA is crucial for tracking academic progress. This article provides a step-by-step guide to calculating overall CGPA across all semesters using different grading scales, including 4.0, 5.0, 7.0, and 10.0.
What is CGPA?
CGPA (Cumulative Grade Point Average) is the average of grade points obtained in all subjects over multiple semesters. It helps institutions assess students’ academic performance on a standardized scale. CGPA provides an overview of a student’s academic consistency and progress throughout their educational journey. Unlike semester GPA (SGPA), which is calculated for a single term, CGPA accumulates performance over the entire course duration. Many universities and colleges use CGPA as a criterion for academic evaluations, scholarship eligibility, and even job placements. A good CGPA can open up better career and higher education opportunities, making it essential for students to maintain a strong academic record.
Key Terms to Know:
- Semester GPA (SGPA): The GPA calculated for one semester.
- Grade Points: The numerical value assigned to grades (e.g., A = 4.0 on a 4.0 scale).
- Credits: The weight assigned to each subject is based on difficulty and hours.
- Total Credits: The sum of credits across all subjects.
- Total Grade Points: The sum of grade points multiplied by the respective subject credits.

How to Calculate Overall CGPA?
The formula for calculating overall CGPA across multiple semesters is:
CGPA=∑(SGPA×TotalSemesterCredits)/ ∑TotalSemesterCredits
Step-by-Step Calculation:
- List all semesters and their respective SGPAs.
- Find the total credits for each semester.
- Multiply the SGPA of each semester by its total credits.
- Sum up the values obtained in step 3.
- Divide the total grade points by the total credits.
- The result is your overall CGPA.
CGPA Calculation on Different Scales
Depending on your institution’s grading system, CGPA is calculated on different scales. Below is a breakdown of how CGPA is determined on various scales.
1. CGPA Calculation on a 4.0 Scale
Grade Point Table (4.0 Scale):
| Grade | Grade Point |
| A+ | 4.0 |
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| F | 0.0 |
Example Calculation:
| Semester | SGPA | Credits |
| 1st | 3.8 | 20 |
| 2nd | 3.6 | 22 |
| 3rd | 3.9 | 18 |
| 4th | 3.7 | 20 |
CGPA=(3.8×20)+(3.6×22)+(3.9×18)+(3.7×20)/20+22+18+20
CGPA=76+79.2+70.2+7480CGPA = 3.78
2. CGPA Calculation on a 5.0 Scale
Grade Point Table (5.0 Scale):
| Grade | Grade Point |
| A+ | 5.0 |
| A | 5.0 |
| A- | 4.7 |
| B+ | 4.3 |
| B | 4.0 |
| B- | 3.7 |
| C+ | 3.3 |
| C | 3.0 |
| C- | 2.7 |
| D+ | 2.3 |
| D | 2.0 |
| F | 0.0 |
Example Calculation:
If the SGPAs for four semesters are 4.5, 4.3, 4.6, and 4.4 with respective credits of 20, 22, 18, and 20, the CGPA calculation follows the same formula as above.
CGPA=(4.5×20)+(4.3×22)+(4.6×18)+(4.4×20)/80 = 4.45
3. CGPA Calculation on a 7.0 Scale
Grade Point Table (7.0 Scale):
| Grade | Grade Point |
| HD | 7.0 |
| D | 6.0 |
| C | 5.0 |
| P | 4.0 |
| F | 0.0 |
Using the same formula, if the SGPAs are 6.5, 6.2, 6.7, and 6.4, CGPA is calculated as: CGPA=(6.5×20)+(6.2×22)+(6.7×18)+(6.4×20)/80 = 6.45
4. CGPA Calculation on a 10.0 Scale
Grade Point Table (10.0 Scale):
| Grade | Grade Point |
| O | 10.0 |
| A+ | 9.0 |
| A | 8.0 |
| B+ | 7.0 |
| B | 6.0 |
| C | 5.0 |
| P | 4.0 |
| F | 0.0 |
Using the same formula, if the SGPAs are 9.2, 8.9, 9.4, and 9.1, CGPA is calculated as: CGPA=(9.2×20)+(8.9×22)+(9.4×18)+(9.1×20)/80 = 9.15
Calculating your overall CGPA is straightforward if you understand the grading scale used by your institution. By following the formula and method outlined above, you can track your academic progress effectively. Whether you are using a 4.0, 5.0, 7.0, or 10.0 scale, the key is to multiply semester GPA by credits and divide by the total credits.
