GPA is calculated by taking the total number of credit points earned and dividing it by the number of hours attempted for a grade.


Every grade has a number value called a grade point associated with it. For example, A has a value of 4.0 while a D has a value of 1.0. You grades are calculated by multiplying your grade the number of course hours, adding up all your courses and averaging them out by dividing it by the total number of course hours.

  • Multiply the credit hour value of each course by the point value of the grade. For example, a three credit hour course in which you earn a B (3 points) is worth 9 credit points.
  • Second, add up the credit points you have earned in all your courses.
  • Finally, divide the total credit points by the number of credit hours you have attempted for a letter grade.

Simple Grade Point Average

Each letter graded course carries grade point value computed as: the total credit hours earned in the course times the point value of the letter grades earned. For example: a student earning an A (point value of 4) in a 3 credit hour course would earn 12 grade points for the course.

Semester GPA

The semester grade point average (GPA) is the sum of all grade points earned in a semester divided by all credit hours attempted for letter grade. Grade Points are calculated by multiplying the number of credit hours assigned to a course by the value of the grade earned in that course.

Cumulative GPA

The average of all grades earned by a student as outlined below is termed the cumulative grade point average. It is used for determining probation and suspension. The cumulative grade point average is defined as the sum of all grade points earned divided by all credit hours attempted for letter grade. Find out more on cumulative GPA.

Weighted GPA

Weighted GPA is calculated after adding extra points for honors or Advanced Placement courses. Basically this means that an A in these courses receives 5 points rather than 4 and a B receives 4 rather than 3, so the overall GPA can exceed 4.0. Find out how to calculate weighted GPA in details.

How To Calculate High School GPA

Calculating high school GPA is easy. There are two parameters to choose from:

  • Letter grade (A,B,C etc.)  and
  • Class type (regular, honors and college)
High school GPA is mostly weighted GPAs, i.e. they factor in class type to calculate weighted high school GPA.
