GPA calculator
Choose a grade and type the credits for each course, and the calculator gives the GPA of those courses on the 4.0 scale. Fill in your GPA so far and its credits to get the cumulative GPA as well.
This answer is for the example courses above. Change a grade or its credits to see your own answer, or clear the courses to start from none.
How it works
Each grade is worth grade points, and each course has credits. The calculator multiplies the points of the grade by the credits of the course, adds the results for all the courses, and divides by the credits added up. Some schools call those products quality points.
The list of grades shows the points of each one. They follow the table in the grading policy of IU Kokomo, where A+ and A are both 4.0 and D- is 0.7. The registrar of Pepperdine University prints the same table without an A+.
Leave a row empty if you took fewer than ten courses. Credits can have decimals, such as 1.5, up to 99 for a course. A course with a grade and no credits, or with credits and no grade, is left out, and the answer says which.
A worked example
Take five courses of 3, 4, 4, 3 and 1 credits, graded A-, B+, B, A and A. Their grade points are 11.1, 13.2, 12, 12 and 4, which add up to 52.3. Over 15 credits that is 3.4867, shown as 3.49.
The bulletin of IU Kokomo works a semester of five courses of 3 credits each, graded A, B, C+, D- and F. The credit points are 12, 9, 6.9, 2.1 and 0, so 30 over 15 credit hours is a GPA of 2.0. The calculator gives 2.00 for the same grades.
The cumulative GPA
To add these courses to what you have earned already, fill in your GPA so far and the credits it covers. The calculator turns them into grade points, 3.25 times 60 is 195, adds the 52.3 of the new courses, and divides by all 75 credits. That is 247.3 over 75, which is 3.30.
The mean of the two GPAs, 3.25 and 3.49, would be 3.37. Here it comes out too high, because it counts the 15 new credits as much as the 60 you had.
What it leaves out
The GPA is unweighted, on the 4.0 scale. It has no extra points for an honors or AP course, because a school that weights its grades has its own rule for them. Pass or fail grades, withdrawals, incompletes and repeated courses are not in it either, so leave those courses out, and for a repeat follow the rule of your school.
The table of your school may differ from the one here. For a figure that counts, compare the result with the GPA that your school gives you.

Questions
How do I calculate my GPA?
Multiply the grade points of each course by its credits, add those up, and divide by the total credits. Five courses of 3, 4, 4, 3 and 1 credits graded A-, B+, B, A and A come to 52.3 grade points over 15 credits, which is a GPA of 3.49.
How do I find a cumulative GPA?
Divide all the grade points you have earned by all the credits, which is how the Notre Dame registrar defines it. With 3.25 over 60 credits so far and 52.3 grade points over 15 credits now, that is 247.3 over 75, or 3.30. The mean of 3.25 and 3.49 would be 3.37, which forgets that the 60 credits weigh more than the 15.
Which grade points does the calculator use?
The table in the grading policy of IU Kokomo: A+ and A are 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3, C 2.0, C- 1.7, D+ 1.3, D 1.0, D- 0.7 and F 0.0. Each grade in the list shows its points.
Does every school use the same grade points?
No. A school prints its own table. The table of Pepperdine has no A+, for example, and IU Kokomo counts A+ as 4.0. Check the table of your school.
What does the calculator do with a course that has no credits?
It leaves the course out and says so under the answer. The same goes for credits with no grade, credits that are not a number, and 0 credits. A row with neither a grade nor credits is just unused.
