The basic formula to calculate CGPA is to add the grade points and divide them by the total number of subjects. The CGPA calculator is a system for educational institutes to measure students' performance.
To Calculate CGPA add the grade points and divide the sum by the total number of subjects. It is advised to be aware of the GPA, Grade Point Average. It represents the average value of the accumulated final grades scored in courses over time.

How to Calculate CGPA?
To calculate CGPA out of ten or to learn how to calculate CGPA from marks, students may divide their percentage by 9.5, and the result obtained would be their CGPA. However, students can calculate CGPA by dividing their total score of grade points for all subjects throughout their semesters by the total number of credit hours attended.
Most universities follow this particular grade system. The table will briefly explain how to calculate CGPA in University.
Grade (Points) | Marks |
S - 10 points | Greater Than 91 |
A - 9 points | 81-90 |
B - 8 points | 71-80 |
C - 7 points | 61-70 |
D - 6 points | 57-60 |
E - 5 points | 50-56 |
F - 0 points | Less Than 50 |
Consider a student who got the following grade in five subjects
- Subject A - 9
- Subject B - 7
- Subject C - 8
- Subject D - 8
- Subject E - 7
Note: Considering the total marks for each subject as 10.
Step 1: Add the grade points of all the 5 subjects
- 9+7+8+8+7 = 39
Step 2: Divide the total by no of subjects, i.e., 5
- 39/5 = 7.8
The CGPA of the candidate is 7.8
CGPA Formula
The CGPA Formula is not complicated at all. To find out the CGPA, students only need to know the basic formula of CGPA which is also known as CGPA calculator. Students need to add all the grade points of the subjects and divide them with the total number of subjects. The CGPA formula is mentioned below:
CGPA Calculator | Sum of Grade Points ÷ Total Number of Subjects |
Subjects | Grade Points |
Subject 1 | 7 |
Subject 2 | 9 |
Subject 3 | 7 |
Subject 4 | 7 |
Subject 5 | 8 |
Total | 38 |
CGPA | 38 ÷ 5 = 7.6 |

How to Calculate CGPA to Percentage?
Students willing to know how much percentage they have obtained in their 10th and 12th board exams can convert their CGPA into a percentage. Below are the steps to convert CGPA into a percentage.
- Students need to add all their subject points and divide them by the total number of subjects they have.
- Now they need to multiply these points with 9.5
CGPA to Percentage Formula | CGPA × 9.5 = Total Percentage |
For example:
A student's 5 subjects points are as follows: 5, 7, 6, 6, 8.
To convert into a percentage, follow the below steps.
- Add these points: 5+7+6+6+8 = 32.
- Now divide by total subjects: 32/5 = 6.4
- Now your CGPA points are 6.4.
- Finally multiply CGPA with 9.5 scale: 6.4×9.5 = 60.8
- So the student's percentage is 60.8%.
This is how students may convert their CGPA to percentages. Some colleges do follow a 10 scale for the conversion of percentage, and in that case, the percentile is 6.4×10 = 64%.

GPA to Percentage Converter
The conversion of GPA to percentage can be done on the basis of knowing the individual GPA of a subject.
GPA Formula:
GPA Formula = ∑Grade Points/ ∑Gradeable Credits |
Below are the steps to calculate GPA
Step 1: Divide the student's GPA with the maximum GPA.
- For example, the maximum GPA for a particular subject is 4 and, the GPA score obtained by the candidate is 3.25 and 3.25/4 = 0.8125
Step 2: Multiply the value with 100 (move the decimal points 2 places to the right, i.e., 0.8125) = 81.25
- Now, the GPA percentage in an individual subject is 81.25%
A few more ways for the conversion of Percentage to GPA are as follows.
Conversion of One Percentage into a 4.0 GPA
Conversion of one percentage into 4 GPA is calculated with a specific formula.
The formulae for this method is,
GPA = (x/20)-1, where "x" is the percentage score of the student
For example:
X = 75%, then GPA = (75/20) - 1 = 2.75
The GPA equivalent of 75% is 2.75.
Conversion of Multiple Grades into 4.0 GPA
To calculate CGPA, the typical score system is followed in most schools. Follow the table below to understand the scoring system followed by most schools.
Grade | Marks |
A | 4 |
A- | 3.7 |
B+ | 3.3 |
B | 3 |
B- | 2.7 |
C+ | 2.3 |
C | 2 |
C- | 1.7 |
D+ | 1.3 |
D | 1 |
D- | 0.7 |
F | 0 |
Below are the steps to convert multiple grades into 4 GPA.
Step 1: Now assume students got the following grades A, B, C-, and D in Physics, Maths, Literature, and Gym, respectively.
Step 2: Add the score value: 4+3+1.7+1 = 9.7
Step 3: Divide the sum with the number of subjects: 9.7/4 = 2.4
The GPA equivalent is 2.4
Hence, to learn how to calculate CGPA, one must follow the rules and should have adequate numbers. The marks should be entered carefully to overcome the chances of error.

Merits and Demerits of CGPA Conversion
Now that students know how to calculate the CGPA and derive the percentage, some merits and demerits are associated with the same.
Merits | Demerits |
The CGPA reduces the tension and pressure of scoring high marks in the exam as the actual marks are not mentioned in the results/ report cards. | Students often tend to underperform themselves as they know the actual marks will be converted into the grading system. |
Additionally, students get an opportunity to weigh their strengths and weaknesses. Further, they can work on improving it. | The students' performance is hampered, and the CGPA does not reflect the actual performance. |
