What this GPA calculator does
Your GPA (grade point average) is the weighted average of your course grades, where each grade is weighted by how many credit hours the course is worth. A four-credit class pulls on your GPA nearly twice as hard as a class worth two and a half credits, so a simple average of letter grades gets the answer wrong. This calculator does the weighting for you.
How to use it
Enter one course per line in the format:
Course Name, Letter Grade, Credit HoursFor example:
Biology, A, 4
Calculus, B+, 3
History, C, 3The course name is optional — A, 4 on its own works fine — and blank lines are ignored, so you can space things out. Choose your grading scale, and the result updates as you type. You'll get your weighted GPA, total credit hours, and total quality points (the sum of grade points × credits), plus a count of the courses included.
How GPA is calculated
For each course, the letter grade becomes a grade point on a numeric scale, which is multiplied by the course's credit hours to give its quality points:
GPA = Σ(grade point × credit hours) ÷ Σ(credit hours)So an A (4.0) in a 4-credit course contributes 16 quality points, while a B+ (3.3) in a 3-credit course contributes 9.9. Add up every course's quality points, divide by the total credit hours, and you have your weighted GPA.
The grading scales
The 4.0 scale is the US standard: A and A+ both equal 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down in 0.3–0.4 steps to F at 0.0. The 4.3 scale is identical except that an A+ is rewarded above a plain A, at 4.3 — the convention some universities use. Pick whichever your school reports.
Frequently asked questions
What's the difference between weighted and unweighted GPA here? This tool weights by credit hours, which is how nearly every college computes a term or cumulative GPA. It does not add honors/AP bonus points — that's a separate high-school "weighted GPA" convention.
Can I use half credits? Yes. Any positive number of credit hours is accepted, including values like 1.5 or 0.5.
Does it handle plus and minus grades? Yes — A-, B+, C-, and the rest all map to their standard grade points.
