How To Calculate Cgpa From Percentage

Calculating CGPA from percentage is a crucial aspect of evaluating academic performance. Many institutions and job applications require this conversion to determine a student’s overall grade point average. Understanding the formula and process for obtaining CGPA from percentage is essential for students and professionals alike. In this article, we will explore the steps involved in this calculation.

To calculate CGPA from percentage, it is important to first understand the grading scale used by your educational institution. Most institutions follow a 10-point grading system where each grade represents a specific range of marks. For instance, an A+ may correspond to marks ranging from 90-100%, while a B might correspond to 80-89% and so on. In this system, the CGPA is calculated by assigning each grade a certain weightage, based on the predetermined grading scale.

For example, if your institution follows a 10-point grading scale and an A+ grade carries a weightage of 10, then you would multiply the credit hours of each course with the grade points assigned to it. Adding up the total grade points and dividing it by the total number of credit hours will yield your CGPA. This method allows for a fair evaluation of a student’s performance across different courses and credit hours.

Calculating CGPA from percentage provides a standardized measure to assess academic achievement. This is particularly important when applying for further studies or employment opportunities. Employers and universities often have specific CGPA requirements for admissions or job eligibility criteria. By converting percentage to CGPA, students can meet these requirements and gain a fair advantage in their applications.

In conclusion, understanding how to calculate CGPA from percentage is crucial for students and professionals. By familiarizing oneself with the grading scale and the weightage assigned to each grade, one can convert their percentage marks into a standardized CGPA. This not only provides a fair assessment of academic performance but also helps meet the requirements set by educational institutions and employers. So, the next time you need to calculate your CGPA, remember to refer to the grading scale and follow the necessary steps to obtain an accurate result.


Calculating CGPA (Cumulative Grade Point Average) from a percentage is a vital process carried out by students to assess their academic performance. It is essential to know how to convert percentage to CGPA accurately. This article will provide a step-by-step guide on how to calculate CGPA from a percentage.

Step 1: Understand the Grading System

Before calculating CGPA from a percentage, it is crucial to be familiar with the grading system used by your educational institution. Different institutions may have distinct grading scales, such as a 4.0 scale or a 10.0 scale. Usually, the grading system consists of letter grades or grade points assigned to different percentage ranges. Make sure you have this information at hand.

Step 2: Assign Grade Points

Based on the grading system used by your institution, assign grade points to the corresponding letter grades. For instance, a 4.0 scale commonly associates an ‘A’ grade with 4.0 grade points, a ‘B’ grade with 3.0 grade points, and so on. Note down the grade point values for each letter grade.

Step 3: Determine Percentage Equivalent

Divide the obtained percentage by the maximum marks attainable and multiply the result by 100. This will provide you with the percentage equivalent for that particular subject or semester.

Step 4: Calculate Cumulative Grade Points

Next, convert the obtained percentage equivalent to grade points using the grade point values assigned in step 2. For example, if your institution uses a 4.0 scale and you scored 80% in a subject, which corresponds to the letter grade ‘B,’ with 3.0 grade points, your equivalent grade points for that subject would be 3.0.

Step 5: Weighted Average Calculation

To calculate CGPA, you need to consider the credit hours or weightage assigned to each subject. Multiply the grade points obtained in each subject by the respective credit hours.

Step 6: Total Grade Points and Total Credit Hours

Sum up all the weighted grade points obtained in step 5 to get the total grade points. Similarly, calculate the total credit hours by summing up the credit hours of all the subjects.

Step 7: Calculate CGPA

Finally, divide the total grade points by the total credit hours. The result will be your CGPA. It is typically rounded to two decimal places.


Calculating CGPA from a percentage involves understanding the grading system, assigning grade points, determining percentage equivalents, calculating cumulative grade points, and obtaining the weighted average. By following the step-by-step guide mentioned above, you can accurately calculate your CGPA and evaluate your academic performance.

In conclusion, calculating CGPA from percentage is a straightforward process that can be easily understood and applied. By converting the percentage to a scale of 10 and assigning the corresponding grade points, one can determine the CGPA. This method allows for a standardized measure of academic performance, regardless of the grading system used by different educational institutions. It is important to note that CGPA is a useful tool for evaluating a student’s overall performance and can be utilized for various purposes including scholarships, job applications, and further academic pursuits. With the clear step-by-step approach outlined in this article, individuals can confidently calculate their CGPA, gaining a better understanding of their academic achievements.

FAQ – How To Calculate CGPA From Percentage

1) What is CGPA?

CGPA stands for Cumulative Grade Point Average. It is a grading system used by educational institutions to evaluate a student’s overall academic performance.

2) How is CGPA different from percentage?

Percentage is a numerical representation of a student’s performance based on the total marks obtained in a subject or course. On the other hand, CGPA is an average of the grades obtained in all the subjects or courses over a specific period.

3) How can I calculate CGPA from percentage?

To calculate CGPA from percentage, you need to divide the percentage obtained by the maximum percentage and then multiply the result by 10. This formula can be represented as follows:
CGPA = (Percentage / Maximum Percentage) * 10

4) What is the maximum percentage in CGPA calculation?

The maximum percentage in CGPA calculation is usually 100%.

5) Can CGPA be greater than 10?

No, CGPA cannot be greater than 10. It is generally capped at 10 since it represents a student’s overall performance on a scale of 1 to 10.

6) Is CGPA applicable for all education systems?

CGPA is applicable for most education systems that follow a grading system. However, the scale and calculation method may vary between different educational institutions and countries.

7) Can CGPA be converted back to percentage?

Yes, CGPA can be converted back to percentage by multiplying the CGPA by the maximum percentage and then dividing the result by 10. The formula for converting CGPA to percentage is as follows:
Percentage = (CGPA * 10) / Maximum Percentage

8) How is CGPA useful for college admissions?

CGPA provides a comprehensive evaluation of a student’s overall academic performance rather than focusing solely on individual subject marks. It helps colleges and universities assess a student’s capabilities and potential for higher education.

9) Are there any additional factors considered in CGPA calculation?

In some cases, certain factors like credit hours or subject difficulty level may also be involved in CGPA calculation. However, the basic calculation method mentioned earlier is widely used.

10) Can you give an example of CGPA calculation from percentage?

Sure, suppose a student has obtained 80% in a particular course out of a maximum of 100%. To calculate the CGPA, we use the formula:
CGPA = (Percentage / Maximum Percentage) * 10
CGPA = (80 / 100) * 10
CGPA = 8

Note: This example assumes a maximum percentage of 100% for simplicity.
