How to Use This Calculator
Enter your letter grades as a comma-separated list (e.g. A,B+,C) and the corresponding credit hours for each course (e.g. 3,4,3). The calculator outputs your weighted GPA on the 4.0 scale.
Formula
GPA = Σ(Grade Points × Credits) / Σ Credits
Example
Grades: A,B+,C | Credits: 3,4,3 → GPA = (12+13.2+6)/10 = 3.12
Frequently Asked Questions
- GPA (Grade Point Average) is the weighted average of your grade points across all courses, where each course is weighted by its credit hours. In most US institutions, the scale runs from 0.0 to 4.0, where 4.0 represents straight A grades. GPA is calculated as: GPA = Σ(grade points × credit hours) ÷ total credit hours. For example, if you earned an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course, your GPA = (4.0×3 + 3.0×4) ÷ 7 = 24/7 ≈ 3.43.
- This calculator accepts the standard US letter grade system: A+, A, A−, B+, B, B−, C+, C, C−, D+, D, D−, and F. Enter them as a comma-separated list (e.g., A,B+,C,A−) matched to a corresponding comma-separated list of credit hours (e.g., 3,4,3,3). Make sure both lists have the same number of items. Note that A+ is mapped to 4.0 in the standard scale — some institutions give A+ a 4.33, but this calculator uses the common 4.0 cap.
- On the standard 4.0 scale: a 4.0 is a perfect GPA (all A grades). A GPA of 3.5–4.0 is generally considered excellent and often qualifies for the Dean's List. A 3.0–3.5 is good and is commonly required for graduate school admission. A 2.0–3.0 is average — many programs require at least a 2.0 to stay enrolled. Below 2.0 may place a student on academic probation. For professional programs like medical or law school, a 3.5+ is typically needed to be competitive.
- The standard 4.0 scale assigns: A+ = 4.0, 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, D− = 0.7, F = 0.0. Note that A and A+ are both 4.0 on the standard scale — a common variation gives A+ a 4.3 boost, but this is not universal. Check your institution's policy if you see a discrepancy. This scale is used by most four-year universities in the United States.
- GPA is a weighted average: GPA = Σ(grade points × credit hours) ÷ Σ(credit hours). Higher-credit courses count more toward your GPA. Example: Grades A (4.0), B+ (3.3), C (2.0) with credits 3, 4, 3. Weighted sum = 4.0×3 + 3.3×4 + 2.0×3 = 12 + 13.2 + 6 = 31.2. Total credits = 10. GPA = 31.2 ÷ 10 = 3.12. A common mistake is computing a simple average of grade points (4.0 + 3.3 + 2.0) / 3 = 3.1, which ignores the credit weight difference.
