How to Calculate GPA Step-by-Step
List Your Courses and Credits
Write down all courses for the semester. Note the credit hours for each course (typically 1-4 credits, found on your course schedule or syllabus).
Convert Grades to Grade Points
Convert each letter grade to its numerical equivalent on your school's scale:
- • 4.0 scale: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0
- • Include +/- adjustments (e.g., B+ = 3.3, B- = 2.7)
Calculate Quality Points
For each course, multiply the grade points by the credit hours. This gives you "quality points" or "grade points earned" for that course.
Example: A (4.0) in 3-credit course = 4.0 × 3 = 12 quality points
Sum and Divide
Add up all quality points from all courses. Add up all credit hours. Divide total quality points by total credits. This is your GPA.
GPA = Σ(Grade Points × Credits) / Σ(Credits)
Complete Example:
Course 1: Calculus I - 4 credits - Grade A (4.0) = 16 quality points
Course 2: English 101 - 3 credits - Grade B+ (3.3) = 9.9 quality points
Course 3: Biology - 4 credits - Grade B (3.0) = 12 quality points
Course 4: History - 3 credits - Grade A- (3.7) = 11.1 quality points
Total: 49 quality points / 14 credits = 3.5 GPA

Common GPA Calculation Mistakes to Avoid
Mistake: Treating all courses equally
A grade in a 1-credit course should NOT count the same as a 4-credit course. Always weight by credits.
Mistake: Mixing different grading scales
Don't combine 4.0 and 10.0 scale grades without converting them first. Use consistent scales.
Mistake: Forgetting +/- grade adjustments
B+ (3.3) is different from B (3.0). Include the adjustment if your school uses plus/minus grading.
Mistake: Including non-graded courses
Pass/Fail or audit courses typically don't count toward GPA. Check your institution's policy.
