College GPA runs on real credit hours, not a simple average — a 4-credit class pulls more weight than a 1-credit seminar. Add your courses below to get your semester GPA in seconds, or add multiple semesters to track your cumulative GPA across your whole degree.

How to Use the College GPA Calculator
- Enter your course name — optional, but useful for keeping track of which grade belongs to which class
- Select your letter grade — choose the grade you earned from the dropdown
- Enter your credit hours — most college courses are worth 3 or 4 credits; check your syllabus for the exact number
- Add more courses — repeat for every class in the semester
- Add your previous GPA (optional) — check the cumulative box and enter your prior GPA and credit hours to see your GPA across your whole degree, not just this semester
The Formula Behind It
Each course's grade is converted to grade points (A = 4.0, B = 3.0, and so on), multiplied by that course's credit hours to get quality points, then all courses are totaled and divided by total credit hours. This is exactly the calculation your registrar runs — a 4-credit A contributes more to your GPA than a 1-credit A, because it carries more weight in both the numerator and denominator.

Frequently Asked Questions
How is college GPA different from high school GPA?
The underlying math is the same credit-weighted formula, but college courses vary more in credit value (commonly 1 to 4 credits per class), and college GPA typically uses the full plus/minus scale more consistently than high school.
How many credits is a typical college class?
Most college courses are worth 3 or 4 credit hours, though labs, seminars, and certain electives can be worth fewer. Check your course catalog or syllabus for the exact credit value.
Does this calculator save my data?
No data is stored or sent anywhere. Everything runs directly in your browser, so refreshing or leaving the page will clear your entries.
Can I calculate my GPA across multiple semesters?
Yes. Check the cumulative GPA option and enter your previous GPA and credit hours alongside your current semester's courses to see your combined GPA across your whole college career.
What GPA scale does this use?
The standard U.S. plus/minus scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0. Some colleges use a simpler scale without plus/minus grades, so check your school's specific policy.
