How It Works
High school GPA can be calculated on two different scales: unweighted (4.0) and weighted (5.0). All courses count equally (no credit hours).
Unweighted GPA Formula:
GPA = Sum(Grade Points) / Number of Courses
Weighted GPA Formula:
GPA = Sum(Grade Points + Course Type Bonus) / Number of Courses
Honors bonus = +0.5 | AP/IB bonus = +1.0
The unweighted GPA treats all courses the same on a 4.0 scale. The weighted GPA adds bonus points for advanced courses: +0.5 for Honors and +1.0 for AP/IB classes. This rewards students who take more challenging coursework and can result in a GPA above 4.0.
Frequently Asked Questions
Unweighted GPA is calculated on a standard 4.0 scale where an A is always worth 4.0 regardless of course difficulty. Weighted GPA accounts for course difficulty by adding extra points for Honors (+0.5) and AP/IB (+1.0) courses, resulting in a scale that can go above 4.0 (typically up to 5.0).
Most colleges consider both weighted and unweighted GPAs. Unweighted GPA shows your raw academic performance, while weighted GPA demonstrates your willingness to take challenging courses. Many selective colleges recalculate your GPA using their own formula, but having a high weighted GPA shows academic rigor.
On the weighted scale, Honors courses add 0.5 grade points and AP/IB courses add 1.0 grade points. So an A in an AP class is worth 5.0 instead of 4.0, and a B in an Honors class is worth 3.5 instead of 3.0. This means taking harder courses can significantly raise your weighted GPA even if your grades are slightly lower.
Most high school students take 6-8 courses per semester. A typical schedule includes core classes (English, Math, Science, Social Studies) plus electives. The calculator starts with 6 rows to match a standard high school schedule, but you can add or remove courses as needed.
For competitive colleges, a 3.5+ unweighted GPA (or 4.0+ weighted) is typically considered strong. Top-tier universities often expect 3.8+ unweighted. However, GPA is just one factor; colleges also consider course rigor, test scores, extracurriculars, and essays.
