High School GPA Calculator

Each course's letter grade converts to grade points on the US 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0). Multiply by credit hours to get quality points, sum across all courses, divide by total credit hours, and round to two decimals. That is the unweighted GPA. The weighted GPA adds a course-type bonus to each grade point (Honors +0.5, AP +1.0, IB HL +1.0, Dual Enrollment +0.5) before the multiplication, so the same A in AP Calculus contributes 5.0 to weighted GPA but 4.0 to unweighted. Both numbers come out in one pass.

This calculator assigns 0 grade points to an F before applying course bonuses, so an F remains 0 in weighted and unweighted results. That is an implementation rule, not a national policy. Districts differ on which grades and courses receive a boost, so check your school handbook.

The college calculator uses an unweighted 4.0 mapping. This high-school calculator also applies fixed course bonuses: Honors +0.5, AP +1.0, IB HL +1.0, and Dual Enrollment +0.5. Its honors labels are internal GPA bands, not a claim that your school awards Latin honors at those cutoffs.

A common transcript convention is 1 credit for a full-year course and 0.5 for a semester course, but districts use other systems. Relative weighting is what matters for the GPA calculation, so enter the credit values printed on your transcript and use one scale consistently.

Policies vary. A college may use the transcript GPA, recalculate selected academic courses, or review grades and course rigor without one converted number. This calculator shows both its weighted and unweighted results, but neither is guaranteed to match an admissions office's method.
