How to use the GPA Calculator
- List each course with credits and grade.
- Add or remove rows.
- Read your GPA and total credits.
How it works
GPA = Σ(Credits × Grade points) ÷ Σ(Credits). Grade points: A+/A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, F = 0.
Worked example
Math 4 credits A− (3.7), English 3 credits B+ (3.3), Biology 3 credits A (4.0): (14.8 + 9.9 + 12) ÷ 10 = 3.67.
Good to know
Schools differ on A+ value and plus/minus grades.
Weighted GPAs for honors or AP classes are not included here.
