How is weighted GPA calculated?

Each course grade is converted to grade points (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0). Quality points equal grade points times credit hours. Weighted GPA is the sum of quality points divided by total credit hours.

Can I enter a percentage instead of a letter grade?

Yes. Enter a number like 87 and it will be converted to a letter grade automatically using the standard scale (90–100 = A, 80–89 = B, 70–79 = C, 60–69 = D, below 60 = F).

What does a 4.0 GPA mean?

A 4.0 GPA is the highest possible on the standard scale and corresponds to straight A grades across all courses.

Do credit hours affect my GPA?

Yes. Courses with more credit hours carry more weight. A B in a 4-credit course contributes more to your GPA than a B in a 1-credit course.

Is a plus/minus grading scale supported?

Yes. The calculator supports A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-, and F for fine-grained GPA computation on the 4.0 scale.

Can I calculate a single course grade from quarters and a final exam?

This tool calculates overall multi-course semester GPA using credit hours. To calculate a single course grade combining quarters and a final exam, use a final grade or weighted grade calculator.

Is my data saved anywhere?

No data is sent to any server. All calculations happen in your browser. Your course list is optionally saved in localStorage so it persists between sessions.
