How does this weighted high school GPA calculator work?

This is an educational tool designed to ease the process of weighing grades and computing averages as it determines the GPA taking account of the grade values, from A+ to F and the five weights (Regular, Honors, College, AP (Advanced Placement) and IB (International Baccalaureate).

Moreover the weighted high school GPA calculator will display as well the un-weighted high school GPA in case you are interested to check it.

Please note that by selecting Add 1 button you can insert more fields in the form so you can put more than the default five items on the list.

Plus the tool above allows you to mix classifications to create your own customized table of classes or courses to retrieve the overall weighted average.

What is the Weighted GPA?

This is the term that refers to the GPA calculated from grades in classes or courses that are considered of increased difficulty and in which the grades A-F have different values.

As listed above, there is a grade top up of 0.5 to 1.00 for some classes. Therefore a calculator that tries to calculate such a GPA needs to take in consideration what kind of classification the class has, as discussed previously.

What are class credits?

Class credits are used to give a precise value to the importance of a certain class to the final GPA. Cumulative credits are calculated by adding all completed credits.

In order to calculate GPA you need to multiply the value of your grade with the number of credits then divide this value to the total number of credits.

Example calculation





















Result: Weighted GPA = 2.98; Unweighted GPA = 2.55
