Step by Step: Calculate CGPA from Marks
If you want to calculate your CGPA from your marks, follow these steps:
Step 1: Calculate the Grade Point from the marks.
First, convert the marks for each subject into grade points (using the grading table).
Step 2: Add the grade points of all subjects.
Total Grade Points = the sum of grade points from all subjects.
Step 3: Divide by the number of subjects.
Formula:
CGPA = Total Grade Points of All Subjects / Number of Subjects
CGPA Calculation Formula
CGPA = Σ Grade Points of Subjects / Total Number of Subjects
If you need the percentage, the formula will be:
Percentage = CGPA × 9.5
Example: Calculate CGPA from Marks
Let’s assume you have 5 subjects and the marks are as follows:
- Maths = 85 → Grade Point = 9
- Science = 92 → Grade Point = 10
- English = 76 → Grade Point = 8
- Hindi = 67 → Grade Point = 7
- Social Science = 81 → Grade Point = 9
Total Grade Points = 9 + 10 + 8 + 7 + 9 = 43
Number of Subjects = 5
Therefore, CGPA = 43 ÷ 5 = 8.6
Percentage = 8.6 × 9.5 = 81.7%
In this way, you can easily calculate your CGPA and then your percentage from your marks.
