GPA Calculator

Use this college GPA calculator to easily calculate the cumulative grade point average (GPA) for a given semester. Enter letter grades (A, B-, C+, etc.) achieved on all relevant courses, as well as the credits for each course. The GPA is then weighted based on the number of credits.

How to calculate your GPA

With the help of this GPA calculator you can calculate your GPA weighted by the number of credits for each course. This is often referred to as CGPA which may stand for "cumulative GPA" or "college GPA". GPA itself stands for Grade Point Average. The software will also compute the sum total of credits from all courses.

To use the calculator, enter the number of courses you have completed (or intend to complete) and then for each course enter the letter grade or expected grade as well as the number of credits it contributes. The overall GPA is weighted based on the number of credits. This means that if you have special courses which are weighted more heavily, you can alter the number of credits to get an exact calculation. For example, if a course has double the weight, just double its credits. Likewise, if it only weighs half as much as other courses, slash the number of credits in half.

For example, say there are four college courses, two of which are worth 3 credits and two are worth 4 credits. Additionally, one of the latter is considered a special course worth 1.5 times a regular course. If you had A-, B, A and B+ respectively, enter these grades and then enter the weights 3, 3, 4, 6 (4 x 1.5 = 6). This way the weighted GPA will correctly reflect the differential contribution of each course.

High school GPA vs college GPA

This calculator can be used for computing both high-school GPA and college GPA, as long as they use the same GPA scale. If you enter grade points directly, then it makes zero difference what kind of grade point average you are looking to get as it becomes a simple weighted average math, no conversion is involved.

How to convert a letter grade to points

Our GPA calculator uses the following table to convert letter grades to grade points for the purpose of computing their weighted average.

Letter grades to grade points conversion table
Letter gradeGrade points
A+ 4.3
A 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
E/F 0.0

If you know the grade points instead of the letter grades, it is preferable to enter them directly. This will ensure the best possible alignment with the GPA scale used by your educational institution.
