High School GPA Calculator
Calculate your high school GPA — weighted or unweighted — on the 4.0 scale. Unweighted treats every class the same: an A is 4.0, a B is 3.0, and so on. Weighted GPA adds a bonus for tougher classes, typically +0.5 for Honors and +1.0 for AP or IB, so a weighted GPA can rise above 4.0 (often to a 5.0 cap). Switch the scale toggle to compare both, since colleges look at each differently. Enter each class’s credits and grade, mark Honors or AP where it applies, and get your GPA instantly. Free, private, and browser-only.
Unweighted: every class on the 4.0 scale; Weighted: +0.5 Honors, +1.0 AP/IB above the base point
- Worked example: an A in an AP class counts as 5.0 weighted but 4.0 unweighted
- Colleges often recalculate to their own scale — knowing both your weighted and unweighted GPA helps.
Frequently asked questions
How is weighted high school GPA calculated?
Start from the 4.0 base point for each grade, then add the rigor bonus: +0.5 for Honors and +1.0 for AP or IB. So an A (4.0) in an AP class becomes 5.0. Credit-weight the boosted points across all classes. The exact bonus varies by school — this calculator uses the common +0.5/+1.0 convention.
Do colleges use weighted or unweighted GPA?
Both. Many colleges recalculate applicants onto their own scale — sometimes stripping weighting, sometimes applying their own. Reporting both your weighted and unweighted GPA is safest, so calculate each with the scale toggle here.
