- Enter each Course Name, select the Letter Grade, and enter the Credit Hours.
- Click + Add Course to add more rows, or click ✕ to remove a course.
- Click Calculate GPA to see your cumulative GPA and total credits.
Formula
Each letter grade is converted to grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0 on a 4.0 scale). The GPA is the weighted average where each course contributes proportionally to its credit hours.
Examples
Math (3 credits, A=4.0), English (3 credits, B=3.0), Science (4 credits, A=4.0).
GPA = (3×4.0 + 3×3.0 + 4×4.0) / (3+3+4) = 37/10 = 3.70
History (3, B=3.0), Chemistry (4, C=2.0), PE (1, A=4.0).
GPA = (3×3.0 + 4×2.0 + 1×4.0) / 8 = 21/8 = 2.625
Honors English (4, A=5.0), Regular Math (3, B=3.0).
GPA = (4×5.0 + 3×3.0) / 7 = 29/7 = 4.14
Frequently Asked Questions
What is the difference between 4.0 and 5.0 scales?
The 4.0 scale is standard for most schools. The 5.0 scale is used at some schools where AP/honors courses can earn up to 5.0 points instead of the maximum 4.0.
Does this calculate weighted GPA?
This calculator computes unweighted GPA. Weighted GPA accounts for course difficulty (AP, Honors, IB) and is typically calculated differently by each school.
How do I improve my GPA?
Focus on earning higher grades in high-credit courses, as they have the greatest impact on your GPA. Retaking courses (where your school allows grade replacement) can also help.
