GPA Calculator
Calculate your cumulative GPA from course grades and credit hours. Supports 4.0 and 5.0 scales with weighted credits.
Cumulative GPA
3.65 / 4.00
Total credits
10
Quality points
36.5
Method
How this calculator works
Each course contributes grade points equal to its grade points × credits. The cumulative GPA is the total quality points divided by the total credits.
gpa = Σ (gradePoints × credits) / Σ credits
# Example (4.0 scale)
A (3 credits) → 4.0 × 3 = 12.0
B+ (4 credits) → 3.3 × 4 = 13.2
A- (3 credits) → 3.7 × 3 = 11.1
────
quality points = 36.3
total credits = 10
gpa = 3.63- Pick the grading scale your institution uses (4.0, 4.3, 10-point, or percentage).
- For each course, choose the letter grade (or enter a percentage) and the number of credits.
- The calculator multiplies each grade’s point value by its credit count to get quality points.
- It sums all quality points and divides by total credits to get your weighted GPA.
- Add or remove courses on the fly — the result updates instantly.
