The formula followed by Anna University to calculate CGPA/GPA is:

GPA/CGPA= (i=1nCi*GPi) (i=1nCi)


  • Ci is the credit points for a course.
  • GPi is the grade point obtained for a course
  • n is the number of all the courses cleared successfully in a semester.

Here’s an example of credits earned and the CGPA calculated for a student in a semester.

Course nameCredit points assigned for the courseGrade scored
Engineering Mathematics 14B
Engineering Chemistry4A
C programming4O
Computer Aided Drawing lab1A+
Japanese Spoken Language3A+

According to Anna University’s grading regulations 2021,

Score for B will fall between 51-60

Score for A is between 71-80

And for A+ it will be 81-90 

Mark range for O is 91-100

So his/her CGPA will be,

CGPA = [(4*56) + (4*78) + ((4*97) + (1*85) + (3*83)]


The final result will be CGPA = 7.862
