How to Calculate GPA
How to calculate GPA is a common question for students trying to track their academic performance or prepare college applications. Grade Point Average (GPA) converts letter grades into a numerical scale, making it easier to compare performance across subjects.
The GPA Formula
The general formula for how to calculate GPA is:
GPA = Total Grade Points Earned ÷ Total Credit Hours Attempted
Each letter grade is assigned a grade point value, typically on a 4.0 scale:
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
Step-by-Step Example
Here’s how to calculate GPA using a sample semester:
- Course 1: Grade A (4.0), 3 credit hours → 4.0 × 3 = 12 points
- Course 2: Grade B (3.0), 4 credit hours → 3.0 × 4 = 12 points
- Course 3: Grade C (2.0), 3 credit hours → 2.0 × 3 = 6 points
- Total grade points: 12 + 12 + 6 = 30
- Total credit hours: 3 + 4 + 3 = 10
- GPA = 30 ÷ 10 = 3.0
In this example, the student’s GPA for the semester is 3.0.
Weighted vs Unweighted GPA
When learning how to calculate GPA, it’s important to know the difference between weighted and unweighted systems. Unweighted GPA treats all courses equally on a 4.0 scale, while weighted GPA gives extra points for honors, AP, or IB courses, sometimes allowing GPAs above 4.0.
Cumulative GPA
Your cumulative GPA reflects your performance across all semesters combined, not just one term. To calculate it, add up grade points and credit hours from every semester before dividing, using the same formula shown above.
For official guidance on GPA systems and academic standards, resources like Khan Academy’s study skills section offer helpful context for students.

FAQs
1. What is the formula for how to calculate GPA?
GPA is calculated by dividing total grade points earned by total credit hours attempted.
2. What does a 4.0 GPA mean?
A 4.0 GPA typically means a student has earned straight A’s across all their courses on an unweighted scale.
3. How is weighted GPA different from unweighted GPA?
Weighted GPA gives additional points for advanced courses like AP or IB, while unweighted GPA treats all courses equally.
4. Can GPA be higher than 4.0?
Yes, weighted GPA scales can exceed 4.0 due to bonus points awarded for honors or advanced coursework.
Knowing how to calculate GPA helps students track academic progress and understand exactly where they stand each semester.
