What Is a Weighted GPA Calculator?
A Weighted GPA Calculator estimates your grade point average while considering both your grades and the difficulty of your courses. Advanced courses can receive additional grade points, which means a weighted GPA may be higher than a standard unweighted GPA.
This calculator supports Regular, Honors, and AP/IB course levels. It also considers course credits, so classes with more credits have a proportionally greater effect on the final result.
Regular
Uses the standard 4.0 grade scale without an additional course difficulty bonus.
Honors
Adds 0.5 points to the standard grade-point value in this calculator.
AP / IB
Adds 1.0 point to the standard grade-point value for advanced AP or IB courses.
How Does the Weighted GPA Calculator Work?
The calculator converts each selected letter grade into grade points. It then adds the selected course-level bonus and multiplies the result by the number of course credits.
After all courses have been processed, the calculator divides the combined weighted quality points by the total number of credits.

Weighted GPA vs. Unweighted GPA
An unweighted GPA normally evaluates grades using the same standard scale regardless of course difficulty. A weighted GPA can assign additional points to advanced classes such as Honors, AP, or IB courses.
For example, an A may equal 4.0 in a regular class, 4.5 in an Honors class, and 5.0 in an AP or IB class under the weighting system used by this calculator.
Why Do Course Credits Matter?
Credits determine how much influence a course has on your overall GPA. A course worth more credits contributes more quality points than a lower-credit course with the same grade.
