Formula & How It Works
Weighted GPA Calculation Formula
Multiplies each course grade point value by credit hours, sums all points, and divides by total credits.
Worked Examples
Four Course Semester
Input: 3 courses A (4.0, 3 cr), 1 course B (3.0, 3 cr)
Explanation: (4*3 + 4*3 + 4*3 + 3*3) / 12 = 45 / 12 = 3.75.
Weighted AP Class
Input: AP Calculus A (5.0, 4 cr), English B (3.0, 3 cr)
Explanation: (5*4 + 3*3) / 7 = 29 / 7 = 4.14.
Straight A Semester
Input: 5 classes grade A (15 credits total)
Explanation: 60 / 15 = 4.00.
Frequently Asked Questions
How is GPA calculated?▼
Multiply each course's grade points by its credit hours, add all quality points together, and divide by total attempted credits.
What is the difference between weighted and unweighted GPA?▼
Unweighted GPA caps at 4.0 regardless of difficulty, while weighted GPA awards extra points (+0.5 or +1.0) for honors and AP/IB courses.
What GPA is an A-?▼
An A- is worth 3.7 grade points on the standard 4.0 scale.
Can your GPA exceed 4.0?▼
Yes, on a weighted scale with AP, IB, or honors coursework, a GPA can exceed 4.0 (up to 5.0).
Do withdrawn (W) classes affect GPA?▼
Normally no, courses dropped with a 'W' do not factor into GPA calculation.
Is my grade data stored?▼
No, all GPA computations run locally in your browser and are never uploaded.

⚠️ Common Pitfalls to Avoid
- •Treating 1-credit lab courses with the same weight as 4-credit lecture classes.
- •Forgetting that plus/minus grades alter grade points (e.g. B+ is 3.3, B- is 2.7).
💡 Practical Real-World Uses
- •College students tracking academic standing and Dean's List eligibility.
- •High school seniors calculating weighted GPA for college admissions applications.
- •Scholarship applicants verifying minimum GPA qualification thresholds.
