From classes to GPA in three steps
Most calculators get one thing wrong: they assume every school uses the same +0.5 / +1.0 weighting. We don't.

Weighting scales
Five scales — pick the one your school uses
Schools don't agree on how much an AP or Honors class is worth. Here's what an A is worth under each common scale.
| Scale | Hon / AP bonus | Honors A | AP A | Used by |
|---|---|---|---|---|
| Standard | +0.5 / +1.0 | 4.5 | 5.0 | Most US public high schools |
| Conservative | +0.25 / +0.75 | 4.25 | 4.75 | Districts limiting grade inflation |
| Third-step | +0.33 / +0.67 | 4.33 | 4.67 | Schools using thirds |
| Uniform | +1.0 / +1.0 | 5.0 | 5.0 | Treats Honors = AP |
| AP-only | 0 / +1.0 | 4.0 | 5.0 | No Honors bonus |

Frequently asked questions
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses a 4.0 scale where every class is treated equally. Weighted GPA gives extra credit for harder courses — typically +0.5 for Honors and +1.0 for AP, IB, and dual-enrollment classes — so an A in an AP class is worth 5.0 instead of 4.0.
Can a weighted GPA be above 4.0?
Yes. With AP and Honors bonuses, students taking advanced course loads regularly reach 4.2 to 4.7 weighted. The cap depends on your school — most cap at 5.0, but some go higher.
Do colleges look at weighted or unweighted GPA?
Most selective colleges recalculate your GPA on a standard scale and consider course rigor separately. They want to see both that you took challenging classes and that you did well in them.
Why does my school's GPA differ from this calculator?
Schools weight differently. Some only weight AP, others include dual-enrollment, some cap the bonus per semester. Use the school weighting scale dropdown to match your district's policy, or check your school's GPA handbook for the exact formula.
How much does an AP class boost my GPA?
On the standard +1.0 scale, an A in an AP class is worth 5.0 quality points instead of 4.0. Over a year of four AP A's, your weighted GPA can sit at 5.0 while your unweighted stays at 4.0.
Is my data saved if I close the tab?
Yes. Your classes and chosen weighting scale save to your browser's local storage. No account needed, no data sent to any server. Clear your browser data to wipe it.
