The cumulative GPA is the grade point average of all grades a student has secured in a semester or term.
A cumulative grade point average (GPA), or overall GPA, is calculated by dividing a student's total grade points from all semesters by the number of total credit hours. The resulting average gives a more comprehensive picture of a high school or college career than a semester or year GPA.
If you want to calculate your semester GPA, add together all the total points (57) and divide them by the number of credit hours (17). A cumulative GPA calculates all the grade points you have earned across all semesters and finds your grade point average.
