Comment Calculer le GPA
A complete, step-by-step guide to understanding and computing your Note Point Moyen—whether you're in high school, college, or graduate school.
What is GPA and Why Does It Matter?
Your Note Point Moyen (GPA) is a single number that summarizes your academic performance across all of your courses. Universities, scholarship committees, and employers use your GPA to evaluate your academic achievements at a glance.
Whether you're applying to college, applying for financial aid, or just want to track your progress, knowing how to calculate your GPA is an essential student skill.
The GPA Formula
The formula for calculating GPA is straightforward:
Here's what each part means:
- Points: The numerical value of your letter grade (A = 4.0, B = 3.0, etc.)
- Crédits: The number of credit hours the course is worth
- Σ (Sigma): The sum of all courses
Step 1: Know Your Note Point Values
On the standard 4.0 scale used in the United States:
| Note | Points |
|---|---|
| A / 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 |
| F | 0.0 |
Step 2: Multiply Points by Crédits
For each course, multiply the grade point value by the number of credits. This product is called quality points.
Example: A 3-credit course with a grade of B (3.0 points) gives you 3 × 3.0 = 9.0 quality points.
Step 3: Add Up Everything
Sum all of the quality points from all courses. Then sum all of the credit hours. Divide the total quality points by total credits to get your GPA.
Complete Worked Example
| Course | Crédits | Note | Points | Quality Points |
|---|---|---|---|---|
| English 101 | 3 | A | 4.0 | 12.0 |
| Biology 201 | 4 | B+ | 3.3 | 13.2 |
| History 101 | 3 | B | 3.0 | 9.0 |
| Art 100 | 2 | A- | 3.7 | 7.4 |
| Math 150 | 4 | C+ | 2.3 | 9.2 |
Total Quality Points: 12.0 + 13.2 + 9.0 + 7.4 + 9.2 = 50.8
Crédits Totaux: 3 + 4 + 3 + 2 + 4 = 16
GPA = 50.8 ÷ 16 = 3.175 → 3.18 (rounded to two decimal places)
Semester GPA vs. Cumulative GPA
Semester GPA includes only the courses from a single academic term. Cumulative GPA includes all courses across all semesters. The calculation method is the same—the difference is just which courses you include.
To calculate cumulative GPA, enter every course from every semester into the GPA calculator.
Tips for Improving Votre GPA

- Consider retaking courses if your school has a grade replacement policy
- Seek help early—tutoring and study groups can make a big difference

Questions Fréquemment Posées
Generally, pass/fail courses do not affect GPA because no grade points are assigned. However, a "fail" may count as an F at some institutions. Check with your school.
A "W" (withdrawal) typically does not affect your GPA. However, too many withdrawals may affect financial aid or academic standing. Consult your academic advisor.
If all courses carry equal credit, you can simply average the grade points. However, most students have courses with different credit values, making the weighted formula essential.
