GPA Calculator
GPA Calculator works out your grade point average on the standard 4.0 scale. Add a row per course, choose its letter grade and credit hours, and the weighted GPA updates instantly.
Credit hours act as weights, so heavier courses count more toward the final number — just like an official transcript.

How GPA is calculated
Each letter grade maps to grade points on a 4.0 scale: A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0, with pluses and minuses in between. Each course contributes its grade points multiplied by its credit hours.
GPA is the sum of those weighted points divided by the total credit hours. A 3-credit A and a 1-credit C, for instance, average closer to the A because the A carries more weight.
Scales and honors courses
This calculator uses the common unweighted 4.0 scale. Some schools use a weighted scale that adds points for honors or AP courses, pushing a GPA above 4.0 — adjust the grade points if your school does that.
To plan a target GPA, add hypothetical future courses with the grades you expect and watch how the average moves.
