How the High School GPA Calculator works
Unweighted GPA converts each grade to the standard 4.0 scale and averages them. Weighted GPA rewards course rigor first: honors classes add 0.5 and AP or IB classes add 1.0 to the grade points before averaging, which is how weighted GPAs above 4.0 happen.
Weighted points = grade points + 0.5 (honors) or + 1.0 (AP/IB), if passing
Each class counts as one credit here, matching how most high schools compute year GPA from full-year courses. A failed class earns no boost regardless of type, following the common rule that rigor bonuses only apply to passing grades.
Frequently asked questions
What is a good weighted GPA?
It depends on your school's course offerings, but broadly: above 4.0 signals consistent success in advanced classes, and competitive applicants to selective colleges often sit in the 4.3 to 4.8 range on a 5.0 scale.
Do colleges use weighted or unweighted GPA?
Both, and often neither exactly: many admissions offices recalculate GPA on their own scale from your transcript. They see your course rigor either way, so taking harder classes helps under every system.
Does a B in an AP class beat an A in a regular class?
On a weighted scale they tie at 4.0 (3.0 + 1.0 versus 4.0 + 0). Admissions officers commonly say they prefer the A in the AP class, but between these two, the harder course with a B generally reads as stronger.
Why is my school's GPA different from this?
Schools vary: some weight honors at 1.0, some use 4.5 caps, some compute on 100-point scales. This calculator uses the most common +0.5/+1.0 convention; your transcript's number follows your school's specific policy.
