Calculate your grade point average from courses and credits.

How is GPA calculated?
GPA = Σ(grade points × credits) ÷ Σ(credits), using A=4.0, A-=3.7, B+=3.3, B=3.0 and so on. Courses with more credits influence the GPA more, on the common US 4.0 scale. For example, “A 3” and “B 3” give (4.0×3 + 3.0×3) ÷ 6 = 3.5. Enter each course's grade and credit hours to get your weighted average.
Understanding your result
Courses with more credits influence the GPA more. This uses the common US 4.0 scale.
Formula and method
GPA = Σ(grade points × credits) ÷ Σ(credits), using A=4.0, A-=3.7, B+=3.3, B=3.0 and so on.
Assumptions and limitations
The calculator uses the standard US 4.0 scale and cannot apply your institution's specific rules, such as plus and minus values, weighted honours points, or how retaken and pass or fail courses are handled. Always confirm the result against your official transcript. Entries are calculated in your browser and are not saved anywhere.
Worked example
“A 3” and “B 3” give (4.0×3 + 3.0×3) ÷ 6 = 3.5.

About the GPA Calculator
Compute your weighted GPA on a 4.0 scale from your course grades and credit hours.
Who should use this tool
College and university students tracking academic performance, and advisers helping them plan. If you want your weighted GPA on the common US 4.0 scale from a set of courses with their grades and credit hours, this multiplies each grade by its credits and averages them so heavier courses count more.

- Handles several courses in a single calculation
- Runs in your browser with nothing stored
Practical use cases
- Working out your GPA at the end of a term

Frequently asked questions
Which scale is used?
The standard US 4.0 scale with plus/minus grades. Your institution’s scale may differ slightly.
Why do courses with more credits affect my GPA more?
GPA is a weighted average, so each course's grade points are multiplied by its credit hours before the total is divided by the total credits. A four-credit course therefore counts roughly twice as much as a two-credit one, meaning heavier courses move your GPA more.
Does this match my school's official GPA?
It uses the common US 4.0 scale, which many institutions follow, but schools differ on details like plus and minus values, honours weighting and how pass or fail courses count. Treat the result as a reliable estimate and check your official transcript for the definitive figure.
