GPA Calculator
Calculate your grade point average on the 4.0 scale, weighted by credits.
Add each course with its letter grade and credit hours to calculate your GPA on the standard 4.0 scale. Your grade point average updates as you go.
GPA is credit-weighted, so a grade in a 4-credit course counts more than the same grade in a 1-credit course. This tool handles that for you.

Formula
Grade points per course
grade value × credits = quality points
Each letter maps to a value (A = 4.0, B = 3.0, …). Multiply by the course's credits.
GPA
total quality points ÷ total credits = GPA
Add the quality points across all courses and divide by the total credits.

| All A's | A, A, A | GPA 4.00 |
How GPA is calculated
Each letter grade is worth a number of points on the 4.0 scale: A and A+ are 4.0, A− is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. For each course, multiply the grade value by the number of credits to get quality points. Add up all the quality points and divide by the total credits to get your GPA.
Because the average is weighted by credits, larger courses move your GPA more. This unweighted 4.0 scale is the most common in US colleges; some schools use weighted scales for honors or AP courses.
Tips for an accurate result
Use the credit hours from your transcript or syllabus, not the number of class meetings. If your school uses plus/minus grades, include them — they change the result. Pass/fail courses usually do not affect GPA and can be left out.
Frequently asked questions
How is GPA calculated on a 4.0 scale?
Each grade has a point value (A = 4.0, B = 3.0, …). Multiply each by the course credits, add them up, and divide by total credits.
What is the difference between weighted and unweighted GPA?
Unweighted GPA caps at 4.0 and treats all courses equally by difficulty. Weighted GPA gives extra points for honors/AP courses. This tool uses the standard unweighted 4.0 scale.
Do pass/fail courses count?
Usually not — pass/fail grades typically don't affect GPA, so you can leave them out.
Is my information private?
Yes. Your grades are processed in your browser and never sent to a server.
