How to Interpret Your Results
How Your GPA is Calculated
Your Grade Point Average (GPA) represents the average of your final grades across all courses, weighted by the credit hours of each course. A standard GPA calculation follows a straightforward arithmetic progression:
- Assign Grade Points: Each letter grade corresponds to a numeric value on the standard 4.0 scale (e.g., A = 4.0, B = 3.0, C = 2.0).
- Calculate Quality Points: Multiply the grade points earned in a course by the number of credit hours assigned to that course.
- Sum Totals: Add up all the quality points earned, and divide by the total number of credit hours attempted.
Standard 4.0 GPA Conversion Scale
| Letter Grade | Percentage Scale | Standard Grade Points |
|---|---|---|
| A | 93% – 100% | 4.0 |
| A- | 90% – 92% | 3.7 |
| B+ | 87% – 89% | 3.3 |
| B | 83% – 86% | 3.0 |
| B- | 80% – 82% | 2.7 |
| C+ | 77% – 79% | 2.3 |
| C | 73% – 76% | 2.0 |
Utilizing a standard scaling method helps maintain consistency across different institutions and departments.

- GPAGrade Point Average
- The final computed metric representing your overall academic standing.
- Grade PointsLetter Grade Value
- The standard numeric equivalent assigned to each letter grade (e.g., A = 4.0, B = 3.0, C = 2.0).

Step-by-Step Example
GPA Calculation Example
Let's walk through an example of a student who completed three courses in a semester.
Given Example Inputs:
Calculation Steps:
1.Calculate Quality Points per Course
Multiply each course's letter grade point value by its credit hours.
Formula:Quality Points = Grade Points × Credit HoursMATHMath: 4.0 × 4 = 16.0 | English: 3.0 × 3 = 9.0 | Chemistry: 3.7 × 3 = 11.12.Sum Graded Quality Points and Graded Credits
Combine all calculated points and credit hours to find cumulative values for the term.
Formula:Total Points = Σ Quality Points, Total Credits = Σ Graded CreditsMATHTotal Points: 16.0 + 9.0 + 11.1 = 36.1 | Total Credits: 4 + 3 + 3 = 103.Divide Total Quality Points by Total Credits
Divide your cumulative quality points by your total semester graded credits.
Formula:GPA = Total Points / Total CreditsMATHGPA = 36.1 / 10 = 3.61
Frequently Asked Questions
What is a standard 4.0 GPA scale?
The 4.0 scale is the most common grading scale used in US colleges. Letter grades are assigned numeric point values: A=4.0, B=3.0, C=2.0, D=1.0, and F=0.0.
How do credit hours affect my GPA?
Courses with more credit hours have a greater impact on your GPA. A 4-credit course with an 'A' grade earns more quality points than a 1-credit course with an 'A'.
Are Pass/Fail courses included in GPA?
No, Pass/Fail (or Credit/No Credit) courses do not impact your GPA. While they award credit upon passing, no grade points are assigned, so they are excluded from calculations.
What is the difference between semester GPA and cumulative GPA?
Semester GPA is the average of grades earned in a single semester. Cumulative GPA combines grades and credits from all completed semesters during your college career.
