Frequently Asked Questions
GPA is calculated by mapping percentage ranges to GPA values. For the standard scale, 90-100% = 4.0, 80-89% = 3.0, 70-79% = 2.0, 60-69% = 1.0, below 60% = 0.0. The weighted scale adds an extra point for honors/AP courses.
Standard GPA uses a 4.0 scale, while weighted GPA uses a 5.0 scale to account for more challenging courses like honors or AP. A 90% in a weighted course yields a 5.0 instead of 4.0.
This calculator is designed for the typical US grading system. Other countries may use different scales; please adjust accordingly.
