GPA formula
GPA = total grade points / total credits
Grade points are calculated by multiplying each course's credits by the grade value. This calculator uses a common 4.0 scale, but schools can use slightly different scales.

Quick intro
GPA is a credit-weighted average of your course grade points. A three-credit course affects your GPA more than a one-credit lab, so credits matter as much as the letter grade.
Example 1: three college courses
- English: 3 credits, A
- Biology: 4 credits, B+
- History: 3 credits, A-
GPA: 3.65
The four-credit Biology course has more impact than each three-credit course, so its B+ matters more in the total.
Example 2: improving with a high-credit course
- Math: 4 credits, A
- Art: 2 credits, B
- Lab: 1 credit, C+
GPA: 3.33
The A in the four-credit math class pulls the GPA up because it carries the most credits.
What is GPA?
GPA stands for grade point average. It converts letter grades into numbers, then averages them using course credits.
A GPA is often used for academic standing, scholarships, graduation requirements, and transfer applications.
How GPA is calculated
Each letter grade has a grade point value. For example, A is usually 4.0, B+ is usually 3.3, and C is usually 2.0.
Multiply the grade point value by the course credits. Add those grade points across all courses, then divide by total credits.
GPA vs weighted average
A weighted course average uses percentages inside one class. GPA combines multiple classes with credits and letter grade points.
If you want to know your grade in one course, use the weighted grade calculator. If you want a semester or term average, use the GPA calculator.
GPA Calculator FAQ
Does this calculator support A+ as 4.3?+
This version treats A+ as 4.0 because many schools cap the 4.0 scale at 4.0. If your school uses 4.3, adjust the grade points manually using your school's rules.
Should pass/fail courses be included?+
Usually pass/fail courses do not affect GPA unless your school says otherwise. Leave them out if they do not have grade points.
Can I use this for high school GPA?+
Yes for an unweighted 4.0 estimate. Weighted honors or AP GPA systems can differ by school.
Why does a high-credit class change my GPA so much?+
Credits represent the size of the course. A four-credit course contributes more grade points than a one-credit course.
