Your weighted GPA rewards you for taking Honors and AP/IB courses by adding bonus grade points on top of the standard 4.0 scale. This calculator shows that weighted number alongside the unweighted GPA colleges often recompute, so you can see both sides of the picture at once.
How the Weighted GPA Calculator works
Each course you enter has a letter grade, credit hours, and a level: Regular, Honors, or AP/IB. The calculator looks up the standard 4.0-scale base points for your grade, then adds a level bonus — +0.5 for Honors, +1.0 for AP/IB, +0 for Regular. That combined per-course value is multiplied by the course's credit hours, summed across every course, and divided by total credit hours to get your weighted GPA. The same process without the level bonus produces your unweighted GPA.
Inputs and what they mean
Course name is optional and only used to label the breakdown table. Grade is your standard letter grade (A+ through F), each mapped to a fixed 4.0-scale point value. Credits reflects how much a course counts toward your average — most single-period high school classes are 1 credit per semester, though your school may use a different convention. Course level determines the bonus: pick Honors or AP/IB only for courses your school actually classifies that way, since the bonus values (+0.5 and +1.0) are the most common convention but can vary by district.
Limits and edge cases
This calculator uses the most common Honors (+0.5) and AP/IB (+1.0) bonus convention, but some schools use different values, cap the number of weighted courses that count, or weight differently for IB versus AP. Check your school's official grading scale before relying on this number for an application. With zero total credit hours entered, the calculator shows a partial result rather than a GPA, since there's nothing yet to average.
