Weighted GPA with AP/Honors Bonus Calculator
Add honors and AP/IB grade bonuses to your unweighted GPA to see your weighted GPA on the boosted scale.
How it works
weighted GPA = unweighted GPA + ( 0.5 × honors courses + 1.0 × AP/IB courses ) ÷ total courses
Weighted GPA rewards harder courses by adding a bonus to each: a common scheme gives +0.5 for honors and +1.0 for AP or IB, letting a weighted GPA climb above 4.0. Because the bonus is spread across all your courses, its effect on the average depends on what fraction of your load is advanced — two AP classes out of seven move the average far less than they would out of four. This tool applies the standard per-course bonus method most U.S. high schools use, though exact weights vary by district.
Worked example
With an unweighted 3.6 across 7 courses, 2 honors add 2 × 0.5 = 1.0 and 2 AP add 2 × 1.0 = 2.0, for 3.0 bonus points. Divided over 7 courses that is +0.429, so the weighted GPA is 3.6 + 0.429 ≈ 4.03.
Frequently asked questions
How much does an AP class boost GPA?
Under the common scale an AP or IB course adds 1.0 point to that course's grade value (and honors adds 0.5). Averaged into your GPA, the boost is diluted by your other courses, so the effect on the overall figure is smaller than a full point.
Why can a weighted GPA be above 4.0?
The bonuses push advanced courses past the normal 4.0 ceiling — an A in an AP class can count as 5.0. So a schedule heavy in AP and honors classes with strong grades produces a weighted GPA over 4.0.
Do colleges use weighted or unweighted GPA?
Both are seen. Many colleges recalculate GPA on their own scale, often stripping weights or applying their own, and read it alongside course rigor. Report your school's official weighted figure but know admissions may recompute it.
