How do you calculate GPA from percentage?

To convert a percentage to a 4.0 GPA, identify the range your percentage falls into. Generally, 93-100% is a 4.0 (A), 90-92% is a 3.7 (A-), and 80-89% ranges from 2.7 to 3.3. There is no single universal formula, but a standard conversion table is the most accurate method.

What is the formula for Semester GPA?

The formula is: Total Quality Points divided by Total Credit Hours. Quality Points are calculated by multiplying the grade value (e.g., A=4.0) by the credits for that specific course.

Yes, a 3.5 GPA is considered 'Cum Laude' or 'With Honors' at many institutions. It typically indicates a mix of A's and B's and places you above the average college student.

How to Calculate GPA from Percentage

To calculate your GPA, convert each course percentage to a 4.0 scale score, multiply that score by the course credit hours to get "Quality Points," and then divide the Total Quality Points by Total Credits.

GPA = (Σ [Grade Points × Credits]) ÷ Total Credits

Example: A 95% (4.0) in a 3-credit class = 12 points. An 85% (3.0) in a 2-credit class = 6 points.
(12 + 6) ÷ (3 + 2) = 18 ÷ 5 = 3.6 GPA.
