High School GPA Calculator
Calculate weighted and unweighted high school GPA, with extra points for honors, AP and IB classes.
About the High School GPA Calculator
Unweighted GPA uses the plain 4.0 scale. Many high schools add 0.5 points for honors and 1.0 for AP or IB classes, so a weighted GPA can exceed 4.0. Schools differ, and colleges often recalculate GPAs their own way.
The formula
Weighted GPA = Σ((points + bonus) × credits) ÷ Σ credits
- Honors bonus
- +0.5 (typical)
- AP/IB bonus
- +1.0 (typical)
Worked example
Example: Weighted GPA = 3.63
- Input: Courses (grade and credits, one per line): English A 1; Geometry B 1; Biology A- 1 honors; Spanish B+ 1.
- Formula: Weighted GPA = Σ((points + bonus) × credits) ÷ Σ credits
- Result: Weighted GPA = 3.63
- Unweighted: 3.5
- Weighted: 3.63
