How to Calculate & Formula Details
Mathematical Model Formula
GPA = Sum(Grade Points x Credit Hours) / Total Credit Hours. Grade points use the standard 4.0 scale (A = 4.0, A- = 3.7, B+ = 3.3, ... F = 0.0). Weighted GPA adds +0.5 per course for Honors and +1.0 for AP/IB before averaging.A Grade Point Average (GPA) calculator is an essential tool for high school and college students to track their academic standing. Your GPA is a single numerical representation of your overall academic performance across a semester or an entire degree program.
Unweighted vs. Weighted GPA
An unweighted GPA is calculated on a standard 4.0 scale regardless of class difficulty. A weighted GPA gives extra weight to advanced classes like AP (Advanced Placement), IB (International Baccalaureate), or Honors courses, often grading them on a 5.0 scale (A = 5.0, B = 4.0).
Standard 4.0 Letter Grade Scale
- A / A+: 4.0 points
- A-: 3.7 points
- B+: 3.3 points
- B: 3.0 points
- B-: 2.7 points
- C+: 2.3 points
- C: 2.0 points
- D: 1.0 point
- F: 0.0 points
