Weighted GPA Calculator (High School Honors / AP)
Calculate weighted high school GPA with extra points for Honors and AP/IB classes.
What this calculates
Weighted GPA gives extra points for harder classes — Honors typically adds 0.5, AP/IB adds 1.0 to each class's grade. Colleges use weighted GPA differently: some recompute their own version. This calculator gives both weighted and unweighted.
Formula & how it works
Per class: base_grade (A=4, B=3, …) + 0.5 if Honors, +1.0 if AP/IB. Weighted GPA = Σ(weighted_grade × credits) / Σ(credits). Unweighted GPA = Σ(base_grade × credits) / Σ(credits).
Worked example
5 classes (1 credit each): regular A (4.0), regular B (3.0), honors A (4.5), AP A (5.0), AP B (4.0). Weighted = 20.5 / 5 = 4.1. Unweighted = 18.0 / 5 = 3.6.
Frequently asked questions
What scale do colleges use?
Many recalculate to unweighted 4.0 for admissions comparison. Others use their own weighting. Always report both.
Honors vs AP?
Honors = more rigorous than regular but no national exam. AP/IB = standardized curriculum with end-of-course exam.
Can GPA exceed 4.0 unweighted?
Unweighted max is 4.0 (A in everything). Weighted often runs 4.5-5.0 for AP-heavy schedules.
