About the Weighted GPA Calculator
A weighted GPA gives extra grade points for harder classes. On a common scale, honors courses add 0.5 and AP or IB courses add 1.0, so an A in an AP class counts as a 5.0. Your unweighted GPA ignores course level and stays on the 4.0 scale. This calculator shows both so you can see how your coursework affects your GPA.
How to use it
- Enter each class name, the letter grade, the credits and the course level.

Weighted GPA formula
Weighted GPA = Σ(grade points + level bonus) × credits ÷ total credits. An A (4.0) in AP Calculus counts as 5.0, a B (3.0) in an honors class counts as 3.5.

| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
