High School GPA Calculator

How high school GPA works

Unweighted GPA treats every course the same: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0, averaged over courses. Weighted GPA adds a bonus for harder courses — the common model adds 0.5 for honors and 1.0 for AP/IB, so an A in AP Calculus counts as 5.0 instead of 4.0. That is why weighted GPAs can rise above 4.0.

The catch: bonus values differ by district. Some schools add 0.5 for AP instead of 1.0, some weight only AP and not honors, and some report weighted GPA on a 5.0 scale. The calculator lets you change both bonuses, so set them to your school’s table before trusting the weighted figure officially.

Weighted vs unweighted: which do colleges see?

Usually both. Your transcript normally shows the school’s own GPA, and many colleges recompute an unweighted GPA from your letter grades so applicants from different weighting systems compare fairly. A weighted GPA above 4.0 signals course rigor; an unweighted GPA signals raw grades. Neither alone tells the whole story, which is why this calculator shows both side by side.

• Unweighted GPA: pure grades, capped at 4.0.
• Weighted GPA: grades plus difficulty bonuses, can exceed 4.0.
• Class rank, where a school reports it, usually uses the weighted figure.

High school GPA without credit hours

Most high school courses carry equal weight — one credit each — so the calculator treats every course as one credit by default. If your school weights a course differently (a double-period lab, for example), change its credit value and the average follows the same quality-points maths as a college GPA.

AP, IB and dual enrollment

AP and IB courses are the usual source of weighting bonuses, and the calculator treats them the same way: pick the AP level for AP and IB courses and the bonus applies. Dual enrollment is different — those are real college courses taken during high school, so they often appear on both a high school transcript and a future college transcript. How the bonus applies to them is set by the high school, and whether the college counts them again is set by the college, so confirm both before assuming either.

Class rank and the weighted GPA

Where a school reports class rank, it usually ranks on the weighted GPA, because that is the figure that rewards harder courses. That also means rank depends on the cohort: the same weighted GPA can rank differently in a class full of AP students than in one with few. Some schools have stopped ranking entirely for exactly that reason, reporting deciles or nothing at all. Rank is a comparison inside one school, never a national measure.
