How weighted GPA works
GPA is usually calculated on a 4.0 scale by converting each letter grade into grade points, then weighting those grade points by the number of credit hours for the course.
This matters because a four-credit course should influence your GPA more than a one-credit course. A simple average of letter grades does not capture that difference, but a weighted GPA does.
Example GPA calculation
Suppose you earn an A in a 3-credit course, a B in a 4-credit course, and a C in a 2-credit course. You would multiply each grade-point value by its credits, add the totals, and divide by 9 total credits to get the final GPA.
That approach makes the B in the 4-credit course matter more than the C in the 2-credit course, which reflects how most schools calculate GPA.
When to use semester vs cumulative GPA
Use semester GPA when you want to understand performance in one term. Use cumulative GPA when you want a broader view across multiple terms or your full academic record.
If your school uses plus/minus grading, honors weighting, or a scale other than 4.0, double-check how those grades convert before relying on the result for official reporting.
Frequently Asked Questions
How is GPA calculated?
A weighted GPA is calculated by multiplying each course's grade points by its credit hours, adding those totals together, and then dividing by the total number of credit hours.
What is the difference between GPA and a course grade?
A course grade reflects performance in one class. GPA combines multiple classes into a single average, usually weighted by credit hours so larger classes affect the result more.
Can I use this for semester and cumulative GPA?
Yes. Enter only the courses from one term to estimate semester GPA, or include all relevant courses and credit hours to estimate cumulative GPA.
