Calculate My GPA
Your Calculated GPA is:
0.00
Total Credits: 0 | Total Grade Points: 0
How Do You Calculate GPA?
Your Grade Point Average (GPA) is a numerical representation of your academic performance. It is calculated by dividing the total number of grade points earned by the total number of credit hours attempted. This creates a weighted average that accounts for the fact that a 4-credit science lab affects your average more than a 1-credit seminar.
The Step-by-Step GPA Calculation Formula
Assign Point Values: Convert your letter grades into the standard 4.0 scale (A = 4.0, B = 3.0, etc.).Calculate Quality Points: Multiply the point value of the grade by the number of credit hours for that specific course.Sum Totals: Add all the quality points together and add all the credit hours together.Divide: Divide the Total Quality Points by the Total Credit Hours.
Example Calculation
Suppose you took two classes:
Biology (4 Credits): Grade A (4.0). Quality Points: 4 credits × 4.0 = 16.0History (3 Credits): Grade B (3.0). Quality Points: 3 credits × 3.0 = 9.0
Total Quality Points: 16.0 + 9.0 = 25.0Total Credits: 4 + 3 = 7Final GPA: 25.0 ÷ 7 = 3.57
