How it Works:
Unweighted GPA: Calculated as (Total Unweighted Grade Points) / (Total Attempted Credits). Each letter grade (A, B, C, etc.) has a standard point value (e.g., A=4, B=3).
Weighted GPA: Calculated as (Total Weighted Grade Points) / (Total Attempted Credits). Advanced courses add points based on a weighting factor (e.g., an A in a weighted course might be 5 points instead of 4). The "weighted total points" is calculated by summing up the weighted points for each course.
GPA Difference: The absolute difference between your calculated Weighted GPA and Unweighted GPA.

What is Weighted GPA vs Unweighted GPA?
Understanding your Grade Point Average (GPA) is crucial for academic success, college admissions, and scholarship applications. However, not all GPAs are calculated the same way. Schools often use two primary methods: unweighted GPA and weighted GPA. While both aim to represent your academic performance, they differ significantly in how they account for course difficulty. This guide, along with our weighted GPA vs unweighted GPA calculator, will help you grasp these differences and their implications.
The unweighted GPA provides a straightforward measure of your performance based solely on the letter grades you receive. Each letter grade is assigned a standard numerical value (typically A=4, B=3, C=2, D=1, F=0), regardless of the course's subject or difficulty level. This offers a uniform comparison across all students within a school that uses the same unweighted scale.
Conversely, the weighted GPA acknowledges that some courses are inherently more challenging than others. Advanced Placement (AP), International Baccalaureate (IB), Honors, or Dual Enrollment courses often carry extra weight. This means a student earning a 'B' in an AP class might receive the same points (or even more) as a student earning an 'A' in a standard-level class. This system aims to reward students for taking on rigorous coursework.

Common Misconceptions
Misconception 1: Weighted GPA always means a higher GPA. Not necessarily. While it inflates the potential score for harder classes, a student struggling in weighted courses might still have a lower weighted GPA than their unweighted one.
Misconception 2: All schools weight courses the same. This is false. Weighting scales vary significantly between educational institutions. Some might add 0.5 points for honors, while others add a full point for AP/IB courses. Always check your school's specific policy.
Misconception 3: Weighted GPA is the only GPA colleges care about. Colleges typically look at both. They often recalculate GPAs based on their own standards, paying close attention to the rigor of the courses taken (which the weighted GPA reflects).
Weighted GPA vs Unweighted GPA: Formula and Mathematical Explanation
Understanding the core formulas is key to appreciating the difference between weighted and unweighted GPAs.
Unweighted GPA Formula
The unweighted GPA is a simple average of grade points earned per credit hour.
Total Unweighted Grade Points: The sum of points earned for each course, based on a standard scale (e.g., A=4, B=3, C=2, D=1, F=0). For example, if you got an A (4 points) in a 3-credit course, that's 4 * 3 = 12 points. If you got a B (3 points) in a 4-credit course, that's 3 * 4 = 12 points. Sum these up for all courses.
Total Attempted Credits: The total number of credit hours for all courses included in the GPA calculation.
Weighted GPA Formula
The weighted GPA accounts for the increased difficulty of advanced courses. The calculation method involves assigning higher point values to grades earned in these courses.
Total Weighted Grade Points: This is calculated by taking the unweighted grade points for each course and multiplying it by the course's weighting factor, then summing these adjusted values. For example, an 'A' (4 points) in a 3-credit AP course with a 1.2 weighting factor would yield (4 * 1.2) * 3 = 14.4 weighted points.
Total Attempted Credits: This typically remains the same as for the unweighted GPA calculation, representing the total credit hours. Some schools might use weighted credits, but using total credits is more common for comparing the two GPA types directly.

Practical Examples (Real-World Use Cases)
Example 1: Focusing on Standard and Honors Courses
Sarah is a sophomore with the following courses:
English 10 (3 credits, Grade: A, Unweighted Points: 4)
Algebra II (4 credits, Grade: B, Unweighted Points: 3)
Biology (4 credits, Grade: A, Unweighted Points: 4)
World History – Honors (3 credits, Grade: A, Unweighted Points: 4, Weighting Factor: 1.2)
Spanish III (3 credits, Grade: B, Unweighted Points: 3)
Interpretation: Sarah's weighted GPA (3.87) is higher than her unweighted GPA (3.59), reflecting the positive impact of taking an Honors course. This shows colleges she can handle advanced material while maintaining strong grades.
Example 2: Adding AP Courses to the Mix
Consider Michael, who is taking more challenging courses:
Interpretation: Michael's weighted GPA (4.16) significantly exceeds his unweighted GPA (3.53). This is expected given his enrollment in multiple AP courses, which carry a higher weighting factor. Colleges will see this as a strong indicator of academic ambition and capability.

Key Factors That Affect Weighted GPA vs Unweighted GPA Results
Several factors influence the disparity between your weighted and unweighted GPAs:
Number of Weighted Courses: The more AP, IB, Honors, or Dual Enrollment courses you take, the greater the potential difference between your weighted and unweighted GPA. Each weighted course contributes to inflating the weighted score.
Grades in Weighted Courses: Earning high grades (A's and B's) in weighted courses significantly boosts your weighted GPA. Conversely, earning lower grades (C's or below) in these challenging classes can lower your weighted GPA substantially, potentially more than it would affect your unweighted GPA due to the multiplier effect.
Weighting Scale Used by School: Different schools assign different multipliers. A school that assigns a 1.5 factor for AP courses will see a larger GPA difference than a school using a 1.1 factor for the same courses and grades. This is a critical factor for college applications, as they often recalculate GPAs based on standardized weighting.
Credit Hours of Courses: Courses with more credit hours have a larger impact on the overall GPA, whether weighted or unweighted. A high grade in a 5-credit AP course will move the weighted GPA more than a high grade in a 3-credit Honors course.
Total Number of Credits: The more total credits you have accumulated, the less impact any single course (or even a few courses) will have on your overall GPA. This means the initial difference between weighted and unweighted GPA might become less pronounced as you progress through high school.
Performance in Standard vs. Advanced Courses: If your grades are consistently higher in standard courses than in advanced ones, your weighted GPA will be lower than your unweighted GPA might suggest. The GPA difference highlights this balance.
Frequently Asked Questions (FAQ)
What is the standard GPA scale?
The most common unweighted GPA scale is 4.0, where A=4, B=3, C=2, D=1, and F=0. Weighted scales often extend this, allowing GPAs above 4.0 (e.g., A in an AP course might be worth 5 points).
Does weighted GPA matter more for college admissions?
Colleges consider both. They use the unweighted GPA as a baseline and the weighted GPA (or their own recalculation of it) to assess the rigor of your coursework. Taking challenging courses is often viewed favorably, even if it slightly lowers the calculated weighted GPA compared to an easier course load.
Can my weighted GPA be lower than my unweighted GPA?
Yes, it's possible if you perform significantly better in standard courses than in advanced, weighted courses. However, typically, students taking weighted courses aim for high grades in them, resulting in a higher weighted GPA.
How do I find my school's weighting scale?
Your school counselor or the school's official website is the best source. Look for course catalogs or academic policies that detail how AP, IB, Honors, or other advanced courses are weighted.
Should I prioritize weighted courses even if I might get a lower grade?
This is a strategic decision. Colleges value rigor. A 'B' in an AP or Honors class often carries more weight than an 'A' in a standard class. Discuss your course load with your counselor to balance difficulty, potential grades, and your overall academic goals.
What if I took courses at a community college for credit?
Dual enrollment credits earned at a community college may be weighted differently or not at all, depending on your high school's policy and the college's transfer agreements. Check with your counselor.
How does the calculator handle Pass/Fail courses?
This calculator assumes numerical grade points. Pass/Fail courses typically do not earn grade points and may not be included in GPA calculations, or they might be treated as zero-point courses depending on school policy. Consult your school's guidelines.
What does "Total Attempted Credits" mean?
This refers to all the credits for courses you have taken and for which you received a grade (even an F). Dropped courses after the deadline or withdrawal may count as attempted credits depending on the school's policy.
