High School GPA Calculator
Work out your high school GPA — both unweighted and weighted — in one place. Enter each class, mark it Regular, Honors, or AP/IB, choose your letter grade, and add the credits to see both GPA numbers side by side, calculated exactly the way schools report them on transcripts. Honors classes add 0.5 and AP/IB classes add 1.0 to the weighted figure.
Weighted vs unweighted GPA
Unweighted GPA treats every class equally on the 4.0 scale. Weighted GPA rewards harder coursework: Honors classes typically add 0.5 points and AP or IB classes add a full point, which is why weighted GPAs can go above 4.0. Colleges usually look at both, plus the rigor of your schedule.
Frequently asked questions
Which GPA do colleges use? Many recalculate their own from your transcript, but both numbers matter — report whichever your school officially publishes.
What counts as one credit? Most US high schools count a full-year class as 1 credit and a semester class as 0.5.
