How this GPA calculator works
Enter the total grade points and the total credits. The calculator divides the points by the credits and shows the GPA to two decimal places. GPA = total grade points ÷ total credits.
Grade points for one course are that course’s grade multiplied by its credits. The first box is the sum of those products, not the sum of the grades alone. A grade of 9 on 4 credits contributes 36. A grade of 8 on 3 credits contributes 24. A grade of 10 on 3 credits contributes 30. The totals are 90 points and 10 credits, so the GPA is 90 ÷ 10 = 9.00.
Credits change the weight. Grades of 10 and 6 look like an average of 8 if you divide by two courses. With 4 credits and 1 credit, the points are 40 and 6. 46 ÷ 5 = 9.20, which is the figure this page returns. Equal credits are the special case where a plain average of the grades matches the GPA.
The result is always two decimal places. 200 ÷ 24 = 8.333…, shown as 8.33. 85 ÷ 16 = 5.3125, shown as 5.31. The scale is whatever you used when you built the grade points. 100 points over 10 credits is 10.00 on a 10-point scale. 29 points over 10 credits is 2.90 on a 4-point scale. Grade points must be 0 or greater, and credits must be greater than 0. Zero points over 10 credits is 0.00. An empty box, a credit total of 0, or a negative value shows --. This page does not turn the GPA into a percentage.
