About GPA Calculator
Enter each course's grade and credit hours to calculate your grade point average, weighted properly by credits.
The weighting is what makes a GPA more than an average of letters. Each grade converts to points โ typically A=4.0, B=3.0, C=2.0, D=1.0, F=0 โ and is multiplied by that course's credit hours. Total the quality points, divide by total credits, and you have the GPA. This means a four-credit course affects your average twice as much as a two-credit one, which is why a poor grade in a major requirement hurts more than the same grade in a one-credit elective.
Weighted GPA is a separate concept and the source of most confusion. Some institutions add points for advanced courses โ an A in an AP or honours class might count as 5.0 rather than 4.0 โ producing averages above 4.0. Unweighted GPA caps at 4.0 regardless of course difficulty. Which one an application asks for varies, and reporting the wrong one either undersells you or looks like an error.
One practical note on cumulative GPA: as credits accumulate, each new course moves the average less. Early grades therefore carry disproportionate weight over a whole degree, and a low GPA becomes progressively harder to raise not because later grades matter less individually but because they are averaged against an increasingly large body of completed credits.

Frequently asked questions
How is GPA calculated?
Each grade becomes points (typically A=4.0, B=3.0, C=2.0, D=1.0, F=0), multiplied by that course's credit hours to give quality points. Total quality points divided by total credit hours is the GPA.
What is the difference between weighted and unweighted GPA?
Unweighted caps at 4.0 regardless of difficulty. Weighted adds points for advanced courses โ an A in an AP class might count 5.0 โ so weighted GPAs can exceed 4.0. Check which one an application is asking for.
Why do credit hours matter?
Because they weight each grade. A four-credit course influences your average twice as much as a two-credit one, so results in major requirements matter more than in small electives.
Why is it hard to raise a low GPA later?
Because each new course is averaged against all previously completed credits. As your total grows, any single course moves the average less โ which is why early grades carry disproportionate weight across a degree.
