How to Use the GPA Calculator
Add each course with its letter grade and credit hours — the calculator converts each grade to grade points, weights it by credit hours, and totals everything to show your GPA, updating instantly as courses are added, removed, or edited.
The GPA Calculator handles the credit-hour weighting automatically — here's what to enter for an accurate result.
Adding courses accurately
For each course, enter the letter grade received and the correct number of credit hours — credit hours specifically, since that's what determines each course's weight in the final average, not simply the number of courses taken.
Calculating cumulative GPA across semesters
To calculate a cumulative GPA rather than a single semester, add every course from every semester into the same running list — the weighted formula handles the combination correctly as long as all courses and their actual credit hours are included together, rather than averaging separate semester GPAs.
