How to Calculate CGPA and Percentage in CBSE Class 10 and 12: A Complete Guide

Every year, lakhs of students appear for CBSE Class 10 and Class 12 board exams. After the results are announced, one common area of confusion among students and parents is how to calculate CGPA (Cumulative Grade Point Average) and percentage. At Skool Guru, we believe in making academics simpler and more transparent for everyone. So, here's a detailed guide to help you understand and calculate CGPA and convert it to a percentage.

🎯 What is CGPA?

CGPA stands for Cumulative Grade Point Average. It is an average of grade points obtained in all subjects, excluding subjects for additional performance like the 6th subject in Class 10.

The CBSE uses a 10-point grading scale to evaluate a student’s performance in individual subjects. The grades range from A1 (10 points) to E (fail).

📊 Grading System Used by CBSE

✅ How to Calculate CGPA in Class 10

Follow these steps to calculate CGPA:

🔢 Step-by-Step:

• Check the Grade Points you received in the main 5 subjects.
• Add all the grade points.
• Divide by 5 (number of main subjects).

📌 Example:

Suppose you received the following grade points:

English – 9

Mathematics – 10

Science – 8

Social Science – 9

Hindi – 10

Total = 9 + 10 + 8 + 9 + 10 = 46
CGPA = 46 ÷ 5 = 9.2

🧮 How to Convert CGPA into Percentage

CBSE provides a simple formula:

Percentage = CGPA × 9.5

👉 This formula is based on statistical analysis and benchmarking done by CBSE.

💡 Example:

If your CGPA is 9.2, then:

Percentage = 9.2 × 9.5 = 87.4%

📝 Important Notes for Class 12 Students

In Class 12, CBSE does not provide CGPA in the marksheet. You get raw marks (out of 100) for each subject.

To calculate your percentage in Class 12:

Add the marks obtained in the best 5 subjects.

Divide by 5.

Example:

Total = 90 + 88 + 84 + 89 + 92 = 443
Percentage = 443 ÷ 5 = 88.6%

📌 Difference Between CGPA and GPA

CGPA is the cumulative GPA for the entire academic session.

GPA may refer to the grade point average for one term or subject.

Understanding your CGPA and percentage is important, especially when applying for higher education, scholarships, or competitive exams. While CBSE has made grading easy to reduce pressure on students, knowing how to interpret your grades can give you a clear picture of your performance.
