High School GPA Calculator

This calculator works by taking your inputted grade info like letter grades and credits and running them through a mathematical formula to find and display your average GPA.

It specifically takes the letter grade for each course and multiplies it by the corresponding credit. That value is then divided by the sum of all of the credits. Then that new value is your total GPA.

Here’s the most common formula used to calculate GPA:
(GPA) = (grade1 x credit1 + grade2 x credit2 + … + gradeN x creditN) / (credit1 + credit2 + … + creditN)

The value for each letter grade is based on the standard 4.0 grading scale that is used by most schools. Here’s that grading scale:

A+ = 4.0 GPA
A = 4.0 GPA
A- = 3.7 GPA
B+ = 3.3 GPA
B = 3.0 GPA
B- = 2.7 GPA
C+ = 2.3 GPA
C = 2.0 GPA
C- = 1.7 GPA
D+ = 1.3 GPA
D = 1.0 GPA
D- = 0.7 GPA
F = 0.0 GPA
