The working
Unweighted 16 ÷ 5 = 3.20 · Weighted 17.50 ÷ 5 = 3.50

| Algebra II | Regular | 1 | B | 3.0 | 3.0 |
| AP US History | AP/IB | 1 | 88% (B) | 3.0 | 4.0 |
| Chemistry | Regular | 1 | A | 4.0 | 4.0 |

What is the difference between weighted and unweighted GPA?
An unweighted GPA counts every A as 4.0, whatever the class. A weighted GPA adds extra points for harder classes: commonly 0.5 for honors and 1.0 for AP, IB and college classes, so an A in an AP class counts as 5.0. In the example above, the same grades give an unweighted GPA of 3.20 and a weighted GPA of 3.50.
Worked example: 5 classes, one honors and one AP
The working table under the calculator lists each class with its points before and after weighting.
- Letters: percentages turn into letters on the College Board chart (90–100 is an A, 80–89 a B, 70–79 a C).
- Unweighted: add the points, 16, and divide by 5 credits = 3.20.
- Weighted: add 0.5 to the honors grade and 1 to the AP grade first: 17.50 ÷ 5 = 3.50.
Weighted GPA rules differ by school
There is no national rule. North Carolina sets one for every public high school in the state: honors classes add 0.5 and AP, IB and college classes add 1.0, and an F earns 0 at any level. Many other schools use the same numbers; some weight only AP classes, and some cap the weighted GPA. Open Weighting above and change the extra points to match your school's profile or handbook.
Which GPA do colleges use?
Both appear on many transcripts. The College Board notes that colleges may recalculate your GPA with their own rules, for example by leaving out non-core classes such as physical education. That is why it helps to know both numbers. For college grades, use the college GPA calculator.

Its chart lists D as 66–69 and E/F as below 65, which leaves 65 itself unassigned; we count 65 as a D. The chart has no plus or minus grades, so B+ counts as a B on this scale.

Green Bay gives the plus and minus grades in thirds of a point (A- 3.67, B+ 3.33); many schools round these to 3.7 and 3.3, so check your own handbook. F* (fail, no credit), P (pass), INC (incomplete), MX (medical excuse) and NG (no grade) are not counted in GPA. The page sets no honors or AP weighting: the weighting boxes in the calculator are your school's rules. Not counted in GPA: F*, P, INC, MX, NG.
