How GPA is calculated
Each letter grade is worth a number of grade points, from 4.0 for an A to 0 for an F. Multiply each course's points by its credit hours, add everything up, and divide by the total credits. Courses with more credits count more.
The formula
GPA = Σ(grade points × credits) ÷ Σ credits
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.
Worked example
You took four courses: an A (3 credits), a B+ (4), an A− (3), and a C (2).
- Grade points: 4.0 × 3 + 3.3 × 4 + 3.7 × 3 + 2.0 × 2 = 12 + 13.2 + 11.1 + 4 = 40.3.
- Total credits: 3 + 4 + 3 + 2 = 12.
- GPA: 40.3 ÷ 12 ≈ 3.36.
Frequently asked questions
Is an A+ worth more than 4.0?
At most schools an A+ counts as 4.0, the same as an A, and that is what this calculator uses. Some schools give 4.33 for an A+, so check your school’s grading policy.
What's the difference between weighted and unweighted GPA?
An unweighted GPA, like this one, uses the 4.0 scale for every class. A weighted GPA adds extra points for honors, AP, or IB classes, often 0.5 or 1.0, so it can go above 4.0. High schools differ in how they weight.
How do I find my cumulative GPA?
Enter the courses from every term, with their credits. If you already know your total grade points and total credits so far, add the new ones to each: cumulative GPA = all grade points ÷ all credits.
