GPA Calculator
Calculate credit-weighted semester GPA and optionally combine it with prior GPA credits for an updated cumulative GPA.
Calculate semester and cumulative GPA
Add courses, credit hours and letter grades to calculate a credit-weighted GPA. Optionally include a previous cumulative GPA and completed credits for an updated cumulative estimate.

How this GPA calculator works
GPA is usually calculated with credit-weighted grade points. For each course, multiply the grade-point value by the course credits to get quality points. Add all quality points, add all GPA credits, then divide: GPA = total quality points ÷ total GPA credits.
Semester GPA example
If a 3-credit course earns 4.0 grade points, it contributes 12 quality points. A 4-credit course at 3.3 contributes 13.2 quality points. The calculator performs this multiplication for every course and then divides the combined quality points by the combined credits.
Cumulative GPA calculator
If you already have a cumulative GPA, enter that GPA and the number of credits behind it. The tool converts the prior GPA back into prior quality points, adds the new term, and divides by the new total credit count. This avoids incorrectly averaging two GPAs that may represent different numbers of credits.
Grade scales vary by institution
The default selector uses a common 4.0 scale with plus/minus values, but universities and schools can use different point values, exclusions, repeat-course rules, pass/fail handling and rounding methods. Always compare the result with the grading policy on your transcript or registrar website.
