How to calculate CGPA Manually?

Though the results are mentioned in your scorecard,many students do not know how to calculate CGPA. Here, through an example we have explained clearly so that students can understand how CGPA is calculated.

Example: The result details of semester-1 and semester-2 of a PG course is given below. calculate the total CGPA that student gained in that course. 

For Semester-1  

List of subject	Grade letter	Credits for subject
subject-1	O	3
subject-2	A+	3
subject-3	O	3

For Semester-2

List of subject	Grade letter	Credits for subject
subject-A	O	3
subject-B	O	3
subject-C	O	3

Step-1: Now let’s calculate average grade points and total credits for semester-1 & 2 separately

TOTAL GRADE POINT = AVERAGE GRADE POINT X TOTAL CREDITS

Average grade point= sum of grade points / number of subjects

From the grading system table given above- 
grade point for “O”=10 and For  “A+”= 9

For Semester-1 

List of subject	Grade letter	Grade point	Credits for subject
Subject-1	O	10	3
subject-2	A+	9	3
subject-3	O	10	3

Average grade point = sum of grade points/number of subjects
                                 =(10+9+10)/3
                                  =29/3 
                                  =9.66

Total credits = 3+3+3= 9

TOTAL GRADE POINT for semester-1 = AVERAGE GRADE POINT X TOTAL CREDITS
                                                                = 9.66 x 9
                                                                = 86.94

For Semester-2

List of subject	Grade letter	Grade point	Credits for subject
subject-A	O	10	3
subject-B	O	10	3
subject-C	O	10	3

Average grade point  = sum of grade points/number of subjects
                                 =(10+10+10)/3
                                  =30/3 
                                  =10

Total credits = 3+3+3= 9

TOTAL GRADE POINT for semester-2 = AVERAGE GRADE POINT X TOTAL CREDITS
                                                                = 10 x 9
                                                                = 90

Step-2: CGPA calculation

Total CGPA = (SUM OF TOTAL GRADE POINTS) / (SUM OF TOTAL CREDITS)

CGPA = (86.94+90) / (9+9)
            = 176.9 / 18
            = 9.83
Hence, the final CGPA result = 9.83

CGPA to Percentage Conversion

CGPA score can be converted to percentage by multiplying the CGPA value with 10.

Percentage= CGPA x 10

From the above example CGPA score is 9.83
percentage= 9.83 x 10 = 98.3%

How to Calculate GPA Manually? 

Many students commit mistakes in GPA calculation. Here, through an example we have explained clearly so that students can understand how GPA is calculated.

Example: The grade points by the student in semester-1 are given below. Calculate GPA.

List of subject	Grade letter	Credits for subject
subject-1	O	3
subject-2	A+	2
subject-3	A	3

From the grading system table given above- 
grade point for “O”= 10 and For  “A+”= 9, “A”= 8

Hence

For Semester-1 

List of subject	Grade letter	Grade point	Credits for subject
Subject-1	O	10	3
subject-2	A+	9	2
subject-3	O	8	3

GPA= ((10x3)+(9x2)+(8x3)) / (3+2+3)
        = (30+18+24) / 8
        = 72/8
        = 9
Hence GPA of semester-1 is 9.

Key Takeaways: 

• Cumulative grade point average and grade point average both indicate the weightage of marks secured by the student during their course program.
