Weighted GPA vs Unweighted GPA: Key Differences, Calculations, and Impact Explained
Understanding the difference between weighted GPA vs unweighted GPA is essential for students preparing for college applications. These two GPA types represent academic performance in distinct ways, influencing how institutions evaluate a student’s achievements.
While weighted GPAs consider course difficulty, unweighted GPAs provide a basic measure of academic success. Knowing how both work can help students make informed choices about course selection and academic planning, ultimately improving their chances in the competitive college admissions process.
What is a Weighted GPA?
A weighted GPA considers course difficulty, awarding extra points for honors, AP, and IB classes. For example, an A in a standard class may equal 4.0 points, but in an AP course, it could be worth 5.0 points. Weighted scales often vary, commonly using 5.0 or 6.0 point systems, with advanced courses earning higher points. Cumulative GPAs can also be weighted if they include such courses.
Why GPA Calculation Matters?
Calculating GPA accurately helps students gauge academic standing and make informed course selections. Knowing how weighted GPAs work can help students boost their scores strategically.
How to Calculate Weighted GPA:
Here’s a step-by-step guide to calculating a weighted GPA using a modified example. Imagine you’re taking these classes in a semester:
- English Honors (Grade: A)
- Math (Grade: B)
- Biology AP (Grade: A)
- History (Grade: B)
Step 1: Convert Grades to Points Convert letter grades into grade points based on the standard 4.0 scale:
- A in English Honors = 4.0 points
- B in Math = 3.0 points
- A in Biology AP = 4.0 points
- B in History = 3.0 points
Step 2: Apply Weighted Adjustments Add extra points for advanced courses:
- English Honors: 4.0 + 0.5 (Honors boost) = 4.5 points
- Math: 3.0 points (standard weight)
- Biology AP: 4.0 + 1.0 (AP boost) = 5.0 points
- History: 3.0 points (standard weight)
Step 3: Calculate Total Grade Points Multiply the grade points by the number of credits for each class. Assuming each class carries 1 credit:
- English Honors: 4.5 points × 1 credit = 4.5 total points
- Math: 3.0 points × 1 credit = 3.0 total points
- Biology AP: 5.0 points × 1 credit = 5.0 total points
- History: 3.0 points × 1 credit = 3.0 total points
Step 4: Compute the Weighted GPA Add the total points and divide by the number of credits:
- Total Points: 4.5 + 3.0 + 5.0 + 3.0 = 15.5 points
- Total Credits: 4 credits
- Weighted GPA = 15.5 ÷ 4 = 3.875
In this example, your weighted GPA for the semester would be 3.875.
Example:
- English Honors (A): 4.5 points
- Math (B): 3.0 points
- Science AP (A): 5.0 points
- History (B): 3.0 points Total Points: 15.5 | Credits: 4 | Weighted GPA: 3.875
How to get a Weighted GPA?
Taking advanced courses can positively impact your GPA. Some examples of such courses include Honors, AP, and IB classes, which can contribute additional points to your overall score.
- Honors: More challenging than standard courses, adding about 0.5 points. These classes involve a deeper exploration of subjects and often require advanced critical thinking skills.
- AP (Advanced Placement): College-level courses adding 1.0 point, with potential for college credit based on exam scores. AP classes offer a rigorous curriculum and prepare students for college-level coursework, often including exams that can provide college credit if scored well.
- IB (International Baccalaureate): Internationally recognized, also adding 1.0 point per class. IB courses focus on a global curriculum with an emphasis on writing, research, and critical thinking, often culminating in a diploma program requiring multiple courses and assessments.

What is an Unweighted GPA?
An unweighted GPA uses a standard 4.0 scale without considering course difficulty. For example, an A equals 4 points, a B equals 3 points, and so on.
How to Calculate Unweighted GPA:
- List classes and grades.
- Assign standard grade points (A=4, B=3, C=2).
- Add points together and divide by the number of classes.
Example:
- English (A) = 4
- Spanish (A) = 4
- Statistics (B) = 3
- Art History (B) = 3
- Chemistry (C) = 2 Total: 16 points | Classes: 5 | Unweighted GPA: 3.2
Weighted GPA vs Unweighted GPA Comparison:
| Aspect | Weighted GPA | Unweighted GPA |
|---|---|---|
| Definition | Considers course difficulty | Based on grades only |
| Scale | Often up to 5.0 or 6.0 | Typically on a 4.0 scale |
| Impact of Courses | Honors/AP/IB add extra points | All courses graded equally |
| Calculation Example | B in AP = 4 points | B in any class = 3 points |
| Purpose | Reflects course rigor | Provides a basic performance measure |
| College Impact | Shows readiness for college work | Simple grade comparison |

Conclusion:
Weighted and unweighted GPAs offer different insights into a student’s performance. While weighted GPAs reflect course rigor, unweighted GPAs provide a standard measure of grades. Understanding both can help students plan their coursework and present a stronger college application.
