How to use this calculator
- Enter each class in the semester block — names optional.
- Pick the grade (or switch to Percentage input above the calculator).
- Set the course type — Honors adds +0.5 and AP/IB adds +1.0 automatically; that's what makes this GPA "weighted."
- Adjust credits if your classes aren't all 1.0 credit, or switch to Without credits.
- Add semesters for a multi-term weighted GPA — the cumulative number rolls up at the bottom.
- Read the highlighted weighted GPA — the unweighted 4.0 result sits alongside for comparison.
How weighting works
A weighted GPA rewards course rigor. Each grade converts to standard 4.0-scale points first, then a bonus is added based on the class type:
| Class type | Bonus | An A is worth | A B is worth |
|---|---|---|---|
| Regular | — | 4.0 | 3.0 |
| Honors | +0.5 | 4.5 | 3.5 |
| AP / IB | +1.0 | 5.0 | 4.0 |
That's the most common system, but it isn't universal — some districts weight Honors a full point, and some use 6.0 scales. This calculator uses the standard +0.5 / +1.0 convention. No bonus is applied to an F, since you earn weighting by passing the harder class. For the full picture of how scales differ, see the GPA scale explained: 4.0 vs 5.0.
Why your weighted GPA matters
Class rank and many scholarship cutoffs at the high school level run on weighted GPA, because it lets a student taking five APs compete fairly with one taking none. Colleges care about it differently: most look past the number to your transcript, and several big systems recalculate it themselves — the UC system caps honors points, and UF re-weights core academics only.

Frequently asked questions
What's a good weighted GPA?
Above 4.0 means you're earning A-range grades with real rigor in the mix. Applicants to selective colleges commonly sit between 4.3 and 4.8 weighted — but the honest answer depends on how many advanced classes your school offers. Context in what is a good high school GPA.
Should I take the AP class if I might get a B?
On a weighted scale, a B in an AP class (4.0) equals an A in a regular class — and admissions officers consistently say they prefer the harder schedule. A C is where the trade-off gets real. More in how colleges view your GPA.
My school doesn't use credit hours — can I still use this?
Yes. Switch the toggle to Without credits and every class counts equally, or use the dedicated no-credits GPA calculator.
