Weighted GPA Calculator
Honors courses usually add 0.5 points and AP/IB courses add 1.0. This calculator applies that boost per course and caps each course at 5.0.
The rule this calculator applies
Each course starts from its normal 4.0 grade point. The course type then adds a bonus before the credit weighting is applied:
| Course type | Bonus | A becomes | B becomes |
|---|---|---|---|
| Regular | +0.0 | 4.0 | 3.0 |
| Honors | +0.5 | 4.5 | 3.5 |
| AP / IB | +1.0 | 5.0 | 4.0 |
No single course is allowed above 5.0, and an F earns nothing regardless of type. That matches the arrangement used by the majority of US high schools that publish a 5.0 scale.
Weighted GPA = Σ(min(grade point + bonus, 5.0) × credits) ÷ Σ(credits)
Worked example
| Course | Type | Grade | Base | Bonus | Credits | Quality points |
|---|---|---|---|---|---|---|
| AP Physics | AP | B | 3.0 | +1.0 | 1 | 4.0 |
| AP Calculus AB | AP | A− | 3.7 | +1.0 | 1 | 4.7 |
| Honors Chemistry | Honors | B+ | 3.3 | +0.5 | 1 | 3.8 |
| English | Regular | A | 4.0 | 0.0 | 1 | 4.0 |
| Physical Education | Regular | A | 4.0 | 0.0 | 1 | 4.0 |
| Total | — | — | 5 | 20.5 |
20.5 ÷ 5 = 4.10 weighted. The same five grades without bonuses come to 18.0 ÷ 5 = 3.60 unweighted. The 0.50 gap is entirely produced by the two AP courses and the honors course.
Where schools diverge
- Bonus size. +0.5/+1.0 is the most common; some districts give +1.0 to honors as well, which inflates the weighted GPA considerably.
- Which courses qualify. Some schools weight only AP and IB, not honors. Others weight dual-enrollment college courses. PE, band and electives are almost never weighted.
- The ceiling. 5.0 is typical, 6.0 exists, and a few districts cap the overall GPA at 4.5 regardless of individual courses.
- Class rank. A weighted GPA is often used for rank instead of the unweighted figure, which is why students chase AP sections even when the unweighted number is what colleges look at.
Why the number matters less than it looks
A weighted GPA rewards the difficulty of your schedule, so it is a fairer internal ranking tool for a single school than a comparison tool across schools. When colleges compare applicants from different districts, they almost always recompute the figure themselves from the transcript — usually unweighted, sometimes with their own bonus structure. A 4.6 from a district that weights everything is not automatically better than a 3.9 from a district that weights nothing.
Common questions
Can my weighted GPA be lower than my unweighted GPA?
Only if your school applies a penalty, which is rare, or if you entered a negative bonus by mistake. A bonus can never reduce a grade point, so the weighted figure is always greater than or equal to the unweighted one.
Does a B in an AP class beat an A in a regular class?
On a 5.0 weighted scale they tie at 4.0 points. On a +0.5 honors scale the regular A wins, 4.0 to 3.5. Unweighted, the A always wins. This is exactly the calculation students run when deciding whether to take a harder section, and the answer depends on which number the school ranks by.
Do AP exam scores change my GPA?
No. The bonus follows the course designation on the transcript. Exam scores are used for college credit and placement, and are reported separately on applications.
