What is GPA?
GPA, or Grade Point Average, is a standard way of measuring academic achievement in the United States, Canada, and many other countries. It is calculated by assigning a numerical value (grade points) to each letter grade you receive, multiplying by the credit hours of each course, and dividing by the total number of credit hours attempted. GPA is used by colleges, universities, and employers to evaluate academic performance quickly and consistently.
GPA Formula
GPA = Σ(Credits × Grade Points) ÷ Σ(Credits)
To calculate your GPA: multiply each course's credit hours by its grade point value, sum all results, then divide by the total number of credit hours. The result is your GPA on a standard 4.0 scale.
GPA Scale Chart
| Grade | Points | Percentage Range |
|---|
| A+ / A | 4.0 | 93–100% |
| A- | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B- | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 60–66% |
| F | 0.0 | Below 60% |
Example GPA Calculation
Suppose you are taking three courses this semester:
- Mathematics – 4 credits, grade A (4.0) = 16 grade points
- English – 3 credits, grade B+ (3.3) = 9.9 grade points
- History – 3 credits, grade B (3.0) = 9.0 grade points
Total grade points = 16 + 9.9 + 9.0 = 34.9 | Total credits = 4 + 3 + 3 = 10
GPA = 34.9 ÷ 10 = 3.49
Frequently Asked Questions
What is a good GPA?
A good GPA depends on your goals. For most colleges, a GPA of 3.0 (B average) is considered satisfactory. A GPA of 3.5 or higher is considered excellent and may qualify you for honors programs, scholarships, and competitive graduate schools.
How is GPA calculated?
GPA is calculated by multiplying each course's credit hours by its grade point value, adding all results together, then dividing by the total number of credit hours. The formula is: GPA = (Sum of Credit × Grade Points) ÷ (Total Credits).
Does GPA include failed classes?
Yes, failed classes are included in your GPA calculation. An F grade earns 0 grade points, but the credit hours still count toward the total credit denominator. This means a failed course will lower your GPA. However, many schools allow grade replacement if you retake the course and earn a higher grade.
What is the difference between semester GPA and cumulative GPA?
Semester GPA is calculated using only the courses taken in a single semester, while cumulative GPA includes all courses taken across all semesters. Cumulative GPA provides a long-term view of your academic performance and is what most employers and graduate schools consider.
