What is the GPA Calculator?
A GPA calculator computes your grade point average on a 4.0 scale by weighting each course's grade points by its credit hours and dividing by the total credits attempted, giving you an accurate semester or cumulative GPA.

GPA Calculator formula
GPA = Σ(grade_point × credit_hours) ÷ Σ(credit_hours). On a 4.0 scale, A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. Pluses add 0.3 and minuses subtract 0.3 (e.g. A− = 3.7, B+ = 3.3), except A+ which usually stays 4.0.
How to use the GPA calculator
- 1For each course, enter the letter grade you received (A, A−, B+, etc.).
- 2Enter the credit hours for that course (typically 3 or 4).
- 3Add additional rows for every course in the term.
- 4Click Calculate to see your term GPA, total credits and total grade points.
- 5To find cumulative GPA, combine every course across all terms in one list.
Example calculation
Three courses: A (4 credits) = 4.0 × 4 = 16.0 points; B+ (3 credits) = 3.3 × 3 = 9.9 points; C (3 credits) = 2.0 × 3 = 6.0 points. Total points = 31.9; total credits = 10; GPA = 31.9 ÷ 10 = 3.19.
Frequently asked questions
- How is GPA calculated on a 4.0 scale?
- Multiply each course's grade point (A=4.0, B=3.0, C=2.0, D=1.0, F=0) by its credit hours, sum these across all courses, then divide by the total credit hours attempted. The result is your GPA on a 4.0 scale.
- How do I calculate my cumulative GPA?
- List every course from every term, multiply each grade point by its credits, sum them all, and divide by total credits attempted. Entering all courses at once gives the same cumulative GPA as your transcript.
- What is a good GPA?
- A 3.5 GPA (B+ average) is generally considered strong and qualifies for many scholarships and graduate programs. A 3.7+ is competitive for top-tier graduate schools; 3.0 is a common minimum for honor rolls and some programs.
- How do AP, IB or honors credits affect GPA?
- Many high schools add 1.0 to the grade point for honors/AP/IB courses (so an A becomes 5.0). College policies vary — some cap the boost. Check your school's weighting policy and adjust grade points accordingly.
- Does an F affect my GPA?
- Yes. An F earns 0 grade points but the credits still count in the denominator, so it pulls your GPA down sharply. A 3-credit F combined with a 3-credit A gives (4.0×3 + 0×3) ÷ 6 = 2.0 GPA for those two courses.
