How it works

How to calculate it

Convert each letter grade to grade points on the 4.0 scale, add the bonus for honors or AP and IB courses, multiply by the course credits, then divide the total by the credits attempted. The unweighted figure repeats the calculation with no bonus.

Weighted GPA = Σ((grade points + level bonus) × credits) ÷ Σ(credits)

Worked example

Example calculation

An A in an AP course, a B+ in an honors course, and an A− in a regular course, each worth 1 credit, give a weighted GPA of 4.17 and an unweighted GPA of 3.67.

Before you rely on the number

Things worth checking

Bonus values are not standardized. +1.0 for AP and +0.5 for honors is the most common pattern, but some districts use +1.0 for both and a few use none at all.
Colleges frequently recalculate GPA using their own scale, so the unweighted number is usually the safer one to quote on an application.
Weighted GPA above 4.0 is expected once AP or IB courses are included; it is not an error.
For a college transcript on a straight 4.0 scale with credit hours, use the GPA calculator.
