CGPA into Percentage: A Comprehensive Guide

CGPA into Percentage

Cumulative Grade Point Average (CGPA) is a common grading system used in educational institutions worldwide to assess a student’s academic performance. However, when it comes to converting CGPA to a percentage, confusion often arises due to variations in grading scales. In this comprehensive guide, we will explore the concepts of CGPA and its conversion into a percentage. We will delve into the scenarios of 8.3 CGPA, 8.6 CGPA, 8.5 CGPA, and 8.4 CGPA to provide clarity on how to convert these CGPAs into their respective percentage equivalents.

What is CGPA?

Cumulative Grade Point Average (CGPA) is a grading system used to represent a student’s overall academic performance. It is calculated by averaging the Grade Points obtained in each course over a specific period, usually a semester or an academic year. The scale for CGPA Calculator can vary from one educational institution to another, but the most common scale is a 10-point system. In this scale, the highest possible CGPA is 10, which corresponds to an exceptional performance (usually equivalent to an ‘A’ grade in most grading systems).

Understanding the 10-Point CGPA Scale

To understand CGPA better, let’s take a closer look at the 10-point CGPA scale:

  • Grade Point 10: This is the highest grade point and indicates exceptional performance.
  • Grade Point 9: An ‘A+’ grade equivalent, showing excellent performance.
  • Grade Point 8: Equivalent to an ‘A’ grade, reflecting very good performance.
  • Grade Point 7: Corresponds to a ‘B’ grade, indicating good performance.
  • Grade Point 6: Equivalent to a ‘C’ grade, suggesting satisfactory performance.
  • Grade Point 5: Represents a ‘D’ grade, indicating a pass.
  • Grade Point 4: Equivalent to an ‘E’ grade, showing marginal pass performance.
  • Grade Point 3: Indicates a ‘F’ grade, meaning a fail.
  • Grade Point 2: Corresponds to a ‘G’ grade, signifying significant failure.
  • Grade Point 1: The lowest grade point, representing a considerable failure.

Assign Grade Points to Each Course

For each course, you need to assign the corresponding Grade Point based on the grade you received. For example, if you received an ‘A’ grade, assign a Grade Point of 8.

Calculate the Weighted Grade Points

Multiply the Grade Points assigned to each course by the respective credit hours for that course.

Calculate the Total Weighted Grade Points

Sum up all the weighted Grade Points obtained in step 2.

Calculate the CGPA

To calculate your CGPA, divide the total weighted Grade Points by the total credit hours for all courses.

Mathematically, the CGPA formula is as follows:

CGPA = (Total Weighted Grade Points) / (Total Credit Hours)

Converting CGPA into Percentage

Converting CGPA to a percentage can be tricky because the percentage can vary based on the grading system and the specific method used for conversion. In many countries, including India, a common formula is used to convert CGPA to a percentage. This formula is as follows:

Percentage = (CGPA – 0.75) x 10

This formula assumes that the highest CGPA is 10 and the lowest passing CGPA is 4. However, as we mentioned earlier, grading scales can vary. Therefore, it’s essential to check with your educational institution to confirm the specific conversion method they use.

Now, let’s delve into the conversions for the requested CGPA values: 8.3, 8.6, 8.5, and 8.4.

Converting 8.3 CGPA in Percentage

Using the common conversion formula:

  • Percentage = (CGPA – 0.75) x 10
  • Percentage = (8.3 – 0.75) x 10
  • Percentage = (7.55) x 10
  • Percentage = 75.5%

So, an 8.3 CGPA is equivalent to 75.5% using this conversion formula.

Converting 8.6 CGPA in Percentage

Using the same conversion formula:

  • Percentage = (CGPA – 0.75) x 10
  • Percentage = (8.6 – 0.75) x 10
  • Percentage = (7.85) x 10
  • Percentage = 78.5%

An 8.6 CGPA is equivalent to 78.5% using this conversion formula.

Converting 8.5 CGPA in Percentage

Once again, applying the formula:

  • Percentage = (CGPA – 0.75) x 10
  • Percentage = (8.5 – 0.75) x 10
  • Percentage = (7.75) x 10
  • Percentage = 77.5%

Hence, an 8.5 CGPA is equivalent to 77.5% using this conversion formula.

Converting 8.4 CGPA in Percentage

Applying the formula as before:

  • Percentage = (CGPA – 0.75) x 10
  • Percentage = (8.4 – 0.75) x 10
  • Percentage = (7.65) x 10
  • Percentage = 76.5%

So, an 8.4 CGPA is equivalent to 76.5% using this conversion formula.

Factors Affecting CGPA to Percentage Conversion

It’s important to note that the conversion formula mentioned above is not universal, and different institutions or countries may use their own conversion methods. Additionally, some universities might provide a conversion table or a specific formula to convert CGPA to a percentage. To avoid discrepancies, always check with your educational institution for their official conversion method.

Furthermore, the grading scale can vary, with some institutions using a 4-point scale, a 5-point scale, or even a 12-point scale. In such cases, the conversion formula would need to be adjusted accordingly.


Understanding CGPA and its conversion to a percentage is crucial for students, especially when applying for further studies or job opportunities. While the formula provided here is commonly used, it’s essential to verify the specific method your educational institution or prospective employer uses for CGPA to percentage conversion.

In this comprehensive guide, we have explained what CGPA is, how to calculate it, and the standard conversion formula used in many countries. We have also provided percentage conversions for the requested CGPA values of 8.3, 8.6, 8.5, and 8.4, demonstrating the practical application of the formula. Remember that the accuracy of the conversion depends on the grading scale and method employed by your institution, so always verify with your educational authority for precise conversions.
