What This Calculator Does
This weighted GPA calculator computes both your unweighted GPA (standard 4.0 scale) and weighted GPA that accounts for course difficulty. Honors courses receive a 0.5-point bonus, while AP and IB courses receive a full 1.0-point bonus, reflecting the additional rigor of advanced coursework.
The Formula
Each letter grade has a base point value on the 4.0 scale (A = 4.0, B = 3.0, etc.). For the weighted GPA, Honors courses add 0.5 points and AP/IB courses add 1.0 point to each grade. These weighted points are multiplied by course credits, summed, and divided by total credits.
Step-by-Step Example
Enter your courses
Add each course with its name, letter grade, credit hours, and level (Regular, Honors, AP, or IB).
Example course load
AP Biology (A, 4 credits), Honors English (B+, 3 credits), Regular Math (A-, 4 credits), AP History (B, 3 credits).
Calculate unweighted GPA
Base points: 4.0 + 3.3 + 3.7 + 3.0. Weighted by credits: (16 + 9.9 + 14.8 + 9) / 14 = 3.55 unweighted.
Calculate weighted GPA
AP Bio: 5.0 x 4 = 20. Honors Eng: 3.8 x 3 = 11.4. Reg Math: 3.7 x 4 = 14.8. AP Hist: 4.0 x 3 = 12. Weighted GPA: (20 + 11.4 + 14.8 + 12) / 14 = 4.16.
Real-World Use Cases
College Applications
Many colleges consider weighted GPA to evaluate course rigor. A 3.8 weighted GPA with AP courses can be more impressive than a 4.0 with only regular courses.
Scholarship Eligibility
Some scholarships have minimum GPA thresholds. Knowing your weighted GPA helps determine which scholarships you qualify for.
Academic Planning
Model how taking AP or Honors courses would affect your GPA to make informed course selection decisions.
Common Mistakes to Avoid
Confusing weighted and unweighted GPA when reporting to colleges. Some schools want one or the other. Check application requirements.
Assuming all schools weight GPAs the same way. Some add 0.5 for AP instead of 1.0. Use your school official weighting policy.
Not accounting for plus/minus grades. An A- (3.7) is significantly different from an A (4.0) over many courses.
Forgetting that weighted GPA can exceed 4.0. A student with all A grades in AP courses would have a 5.0 weighted GPA.
