Weighted vs Unweighted GPA
3 min read · Updated 2026-10-18
How each is calculated
An unweighted GPA converts every grade to the standard 4.0 scale, so an A is 4.0 whether it came from AP Calculus or an elective. A weighted GPA adds a bonus to the grade points of designated harder courses before averaging, so an A in an AP class becomes 5.0. Compare both with the weighted GPA calculator and the unweighted GPA calculator.
Worked example
| Course | Grade | Unweighted | Weighted |
|---|---|---|---|
| AP Calculus | A | 4.0 | 5.0 |
| Honors English | B+ | 3.3 | 3.8 |
| AP Biology | B | 3.0 | 4.0 |
| Spanish III | A− | 3.7 | 3.7 |
| US History | B+ | 3.3 | 3.3 |
| Art | A | 4.0 | 4.0 |
| Average | 3.55 | 3.97 |
With one credit per course, the totals are 21.3 and 23.8 grade points over six courses. The same transcript reads as a 3.55 unweighted and a 3.97 weighted. Neither number is wrong; they answer different questions.
Why weighted GPAs from different schools don’t match
- Bonus size: +0.5 for Honors and +1.0 for AP or IB is common, but some schools give a full point for Honors or weight dual-enrollment courses too.
- Which courses and years count: some schools weight only certain grades or only junior and senior years.
- The cap: a weighted GPA may top out at 4.5, at 5.0, or have no fixed maximum.
So a 4.2 weighted GPA from one high school and a 4.2 from another are not the same number, which is why colleges look past them.
Which do colleges use?
Many colleges recalculate a consistent GPA — sometimes unweighted, sometimes using only core academic courses — so all applicants are compared on the same basis, then consider course rigor separately. The University of California, for example, recalculates using only 10th- and 11th-grade A–G courses and adds an extra point for at most eight semesters of UC-approved honors courses, no more than four of them from 10th grade. Knowing both numbers helps.
Which number should you report?
Report exactly what the form asks for. If it doesn’t specify, give the GPA on your transcript and say whether it is weighted; many applications have separate boxes for each. Your school profile, which counselors send with your transcript, explains your school’s scale to admissions readers.
