CGPA Calculator
A CGPA (Cumulative Grade Point Average) calculator helps students calculate their overall academic performance based on their grades across multiple semesters or courses.
How to Calculate CGPA
- Convert grades to grade points for each course (common scale):
- A+ = 4.0
- A = 4.0
- A- = 3.7
- B+ = 3.3
- B = 3.0
- B- = 2.7
- C+ = 2.3
- C = 2.0
- D = 1.0
- F = 0.0
- Multiply each course’s grade points by its credit hours to get quality points
- Sum all quality points
- Sum all credit hours
- Divide total quality points by total credit hours to get CGPA
Example Calculation
| Course | Credit Hours | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| Math | 3 | A | 4.0 | 12.0 |
| Science | 4 | B+ | 3.3 | 13.2 |
| English | 2 | A- | 3.7 | 7.4 |
| History | 3 | B | 3.0 | 9.0 |
Total Quality Points = 12.0 + 13.2 + 7.4 + 9.0 = 41.6
Total Credit Hours = 3 + 4 + 2 + 3 = 12
CGPA = 41.6 ÷ 12 = 3.47

What is CGPA?
CGPA (Cumulative Grade Point Average) is the average of all your Grade Point Averages (GPA) across multiple semesters or academic years. Unlike GPA, which measures performance in a single term, CGPA provides a long-term overview of your academic achievements.
Why is CGPA Important?
- University Admissions – Many institutions require a minimum CGPA for eligibility.
- Scholarships & Grants – Higher CGPAs increase chances of financial aid.
- Job Applications – Employers often consider CGPA for fresh graduates.
- Academic Progress Tracking – Helps identify strengths and weaknesses.
How to Calculate CGPA (Step-by-Step Formula)
Calculating CGPA manually is simple if you follow these steps:
Step 1: Convert Grades into Grade Points
Most institutions use a 4.0 scale, but some follow a 10-point system. Here’s a common grading scale:
| Grade | Grade Points (4.0 Scale) | Grade Points (10.0 Scale) |
|---|---|---|
| A+ | 4.0 | 10.0 |
| A | 4.0 | 9.0 |
| A- | 3.7 | 8.0 |
| B+ | 3.3 | 7.0 |
| B | 3.0 | 6.0 |
| B- | 2.7 | 5.0 |
| C+ | 2.3 | 4.0 |
| C | 2.0 | 3.0 |
| D | 1.0 | 2.0 |
| F | 0.0 | 0.0 |
Step 2: Multiply Grade Points by Credit Hours
Each course has a credit weight. Multiply the grade points by the credits to get Quality Points.
Formula:
Quality Points = Grade Points × Credit Hours
Step 3: Sum All Quality Points & Credit Hours
Add up all the Quality Points and Total Credit Hours for the semester.
Step 4: Divide Total Quality Points by Total Credits
CGPA Formula:
[
\text{CGPA} = \frac{\text{Total Quality Points}}{\text{Total Credit Hours}}
]
Example CGPA Calculation
Let’s say a student has the following grades in one semester:
| Course | Credit Hours | Grade | Grade Points (4.0) | Quality Points |
|---|---|---|---|---|
| Mathematics | 4 | A | 4.0 | 16.0 |
| Physics | 3 | B+ | 3.3 | 9.9 |
| Chemistry | 3 | A- | 3.7 | 11.1 |
| English | 2 | B | 3.0 | 6.0 |
Calculations:
- Total Quality Points = 16.0 + 9.9 + 11.1 + 6.0 = 43.0
- Total Credit Hours = 4 + 3 + 3 + 2 = 12
- CGPA = 43.0 / 12 = 3.58
This student’s CGPA for the semester is 3.58 on a 4.0 scale.
GPA vs. CGPA: What’s the Difference?
| Factor | GPA (Grade Point Average) | CGPA (Cumulative GPA) |
|---|---|---|
| Definition | Average for a single semester | Overall average across all semesters |
| Calculation | Based on one term’s grades | Includes all academic terms |
| Flexibility | Changes every semester | More stable, long-term measure |
| Usage | Short-term performance check | Used for final transcripts, job applications |

How to Convert CGPA to Percentage
Different universities use different conversion methods. Here are two common approaches:
1. Direct Multiplication (For 10-Point Scale)
[
\text{Percentage} = \text{CGPA} \times 9.5
]
(Example: 8.5 CGPA × 9.5 = 80.75%)
2. 4.0 Scale Conversion (For US Universities)
Some schools use:
[
\text{Percentage} = (\text{CGPA} / 4.0) \times 100
]
(Example: 3.6 CGPA / 4.0 × 100 = 90%)
Always check your institution’s specific formula.
Tips to Improve Your CGPA
- Focus on High-Credit Courses – They impact CGPA more.
- Retake Low-Grade Subjects – Some schools allow grade replacement.
- Use Active Learning Techniques – Flashcards, group studies, and practice tests help.
- Seek Professor Feedback – Understand where you’re losing marks.
- Balance Course Load – Avoid overloading in a single semester.
FAQs About CGPA Calculation
Q1: Is CGPA the same as overall GPA?
Yes, CGPA is the cumulative GPA that includes all semesters.
Q2: Can I calculate CGPA from percentage?
Yes, reverse the formula:
[
\text{CGPA} = \text{Percentage} / 9.5 \quad (\text{for 10-point scale})
]
Q3: Do failed courses affect CGPA?
Yes, an F grade (0.0 points) lowers your CGPA significantly.
Q4: How do I raise a low CGPA?
- Retake courses with poor grades
- Score higher in upcoming semesters
- Take extra credit courses (if allowed)
Conclusion
Your CGPA is a key indicator of academic success, impacting scholarships, admissions, and career opportunities. By understanding how to calculate CGPA manually or using online tools, you can track and improve your performance effectively.
