A weighted GPA pays you back for taking hard classes: the same A is worth 4.0 in a regular course, 4.5 in Honors, and 5.0 in AP or IB. Tag each class below with its course type and this calculator applies the standard bumps for you, showing your weighted GPA on the 5.0 scale alongside the unweighted 4.0 version colleges will also compute.
Instructions
Enter each class with its letter grade and course type. Honors adds +0.5 per class; AP, IB, and Dual Enrollment add +1.0; Regular adds nothing. Your unweighted GPA appears below the weighted result automatically, so you get both numbers from one set of inputs.

Weighting adds a fixed rigor bonus to the grade points of each advanced class before averaging. The dominant US convention is the one this calculator uses:
Course type
Bump
An A earns
Regular
+0.0
4.0
Honors
+0.5
4.5
AP / IB / Dual Enrollment
+1.0
5.0
The bump attaches to the class, not the grade — a B in AP Calculus (3.0 + 1.0 = 4.0) scores the same as an A in regular math. That equivalence is the whole argument for weighting: it removes the incentive to duck hard courses to protect a GPA.

Weighted vs. Unweighted Side by Side
Both numbers describe the same transcript — unweighted answers "how well did you do?" on a fixed 4.0 scale, while weighted folds in "how hard was the material?" A student with several APs will typically see a gap of 0.3–0.8 between the two, and that gap itself is informative: it's a rough index of schedule rigor. For a full comparison with a graded example transcript scored both ways, see our high school GPA calculator, which computes both numbers with a single toggle.
Is a 5.0 GPA Possible?
Only at the theoretical limit: a 5.0 requires an A in every single class and every single class carrying the full +1.0 bump — a schedule of nothing but AP, IB, or Dual Enrollment. Since most schools require regular-weight courses like PE or health, a true 5.0 is rare-to-impossible in practice. Also note that many schools don't use a 5.0 scale at all: 4.5, 6.0, and higher scales are common, so always check the GPA legend on your own transcript before comparing numbers.
How Colleges Treat Weighted GPA
Because every district weights differently, admissions offices can't compare weighted GPAs across schools — so most don't. The typical process strips your GPA back to a standardized recalculation (often unweighted, core courses only) and then evaluates rigor as its own factor, using the school profile your counselor submits to see how many advanced courses were even offered. The takeaway for course selection: an A in AP beats an A in regular, but a C in AP rarely beats a B in regular in an admissions read. Take the hardest schedule you can earn A's and B's in, and let the admissions chances calculator show you how the whole profile lands.
Frequently Asked Questions
Under the most common system, Honors classes add 0.5 and AP, IB, and Dual Enrollment classes add 1.0 to the grade points earned. Regular classes, electives, and PE get no bump. Every district defines its own list, though — some weight pre-AP or advanced classes too, and a few weight nothing at all.
On the standard 5.0 scale, yes — a 4.5 generally means mostly A's in a schedule heavy with Honors, AP, or IB coursework, which puts a student in range for very selective colleges. Its exact meaning depends on your school's scale and how many advanced classes were available, which is why admissions offices read it alongside your transcript rather than in isolation.
Neither number is taken at face value. Most admissions offices start from the unweighted GPA for a common 4.0 yardstick, then judge rigor by looking directly at how many advanced courses you took relative to what your school offered. Many recalculate your GPA with their own in-house formula, so the weighted figure on your transcript mainly drives class rank locally.
There is no national standard for weighting. Plenty of schools cap the scale at 4.5, add a full point only for AP and IB, or use 6.0, 7.0, or even 12-point systems. The legend on your transcript defines your school's scale, and colleges receive that legend along with your grades, so an unusual scale doesn't disadvantage you.
Generally no. Weighted GPA is a high school construct, and middle school coursework — even high-school-level classes like Algebra I taken in 8th grade — is usually excluded from the high school GPA entirely. Some districts do put those courses on the high school transcript for credit, but typically at regular weight; your counselor can confirm the local policy.
Your AP scores are the other half of the rigor story.
