Calculate your overall GPA
Your cumulative GPA combines the grades from all your courses, weighted by their credit hours, into a single figure. This calculator computes it from your course credits and grades, supporting both 4.0 and 5.0 scales, so you get an accurate overall grade rather than a rough average.
Why credits weight the average
A simple average of your grades is wrong, because courses are not equal: a five-credit course counts more toward your standing than a one-credit one. GPA is a credit-weighted average, so each grade contributes in proportion to its course’s size, which is why a strong grade in a big course lifts your GPA more than the same grade in a small one. The calculator applies that weighting correctly across whichever scale your institution uses.

Frequently Asked Questions
How is cumulative GPA calculated?
As a credit-weighted average of your grades, so each course contributes in proportion to its credit hours rather than counting equally.
Why not just average my grades?
Because courses are not equal. A five-credit course counts more toward your standing than a one-credit one, which a simple average ignores.
Does it support different scales?
Yes. It works on both the 4.0 and 5.0 scales, so it matches whichever your institution uses.
Why does a big course matter more?
Because GPA weights each grade by credit hours, so a strong grade in a large course lifts your GPA more than the same grade in a small one.
Is my data uploaded?
