High School GPA Calculator

Work out both your weighted and unweighted high school GPA. Choose a grade and a level for each class: Honors classes add 0.5 and AP, IB or dual-credit classes add 1.0 to the grade points, the most common weighting in US high schools.

      Formula

      Unweighted GPA = sum of grade points ÷ number of classes
      Weighted grade points = grade points + 0.5 (Honors) or + 1.0 (AP / IB / dual credit)
      Weighted GPA = sum of weighted grade points ÷ number of classes

      How to use it

      1. Choose the final grade for each class.
      2. Set the level of each class: Regular, Honors or AP/IB.
      3. Leave unused rows on “—”.
      4. Compare the weighted and unweighted results.

      Weighted versus unweighted

      An unweighted GPA tops out at 4.0 and treats every class the same. A weighted GPA rewards harder classes: an A in an AP class counts as 5.0 and an A in Honors as 4.5, so the weighted figure can exceed 4.0.

      Colleges see both. Many recalculate GPA their own way from your transcript, so course rigor matters as much as the number.

      Assumptions to check against your school

      Every class here counts equally, as full-year or equal-credit courses do. A failed class earns no weighting bonus. Schools differ: some add 0.5 for AP rather than 1.0, some count A+ as 4.3, and some weight only core subjects. Your school profile or counselor has the exact rules.

      Questions people ask

      What is a B in an AP class worth?

      4.0 weighted (3.0 + 1.0) and 3.0 unweighted. In an Honors class the same B is 3.5 weighted.

      Can my weighted GPA be above 4.0?

      Yes. Straight As with four AP classes out of six works out to (4 × 5.0 + 2 × 4.0) ÷ 6 = 4.67.

      Which GPA do colleges look at?

      Both, alongside the difficulty of your courses. Report whichever the application asks for, and say which it is.
