AP/IB courses add +1.0, honors courses add +0.5
| Course | Grade | Level | Credits |
|---|
| Letter Grade | Grade Points | With +1.0 (AP/IB) | With +0.5 (Honors) |
|---|---|---|---|
| A | 4.0 | 5.0 | 4.5 |
| A- | 3.7 | 4.7 | 4.2 |
| B+ | 3.3 | 4.3 | 3.8 |
| B | 3.0 | 4.0 | 3.5 |
| B- | 2.7 | 3.7 | 3.2 |
| C+ | 2.3 | 3.3 | 2.8 |
| C | 2.0 | 3.0 | 2.5 |
| C- | 1.7 | 2.7 | 2.2 |
| D+ | 1.3 | 2.3 | 1.8 |
| D | 1.0 | 2.0 | 1.5 |
| F | 0.0 | 0.0* | 0.0* |
*Many schools don't add weight to a failing grade, since the whole point of the bump is to reward attempting a hard course without penalizing a near-miss; a weighted F stays 0.0. Plus/minus steps of 0.3 shown here are the most common convention, but your district may round differently or skip minus grades entirely.
| Weighted GPA | Typical Reading |
|---|---|
| 5.0 | Straight As in all AP/IB coursework, the ceiling at most schools |
| 4.5 – 4.9 | Mostly As in mostly AP/IB, top-tier applicant range |
| 4.0 – 4.4 | Strong mix of As and Bs across weighted courses |
| 3.5 – 3.9 | Solid college-bound record with some honors/AP mixed in |
| 3.0 – 3.4 | Average college-bound range; rigor varies |
| Below 3.0 | Signals room to grow; course rigor matters more than the number |
Reading a weighted number without knowing the course load is close to useless, which is exactly why colleges also read your transcript. A 4.2 earned in six AP courses means something different from a 4.2 earned in one.
Weighted GPA exists because an A in AP Calculus and an A in a regular elective shouldn't look identical on paper. High schools respond by adding points to the base 4.0 scale for harder courses. The most widespread scheme, and the one this calculator uses: +1.0 for AP, IB, and often dual enrollment, +0.5 for honors, +0.0 for everything else.
Grade points come from the letter grade (A = 4.0, B = 3.0, and so on in 0.3 steps for plusses and minuses). Each course's weighted points equal its grade points plus its level bump. Multiply by the course's credits, sum across every course, and divide by total credits:
Weighted GPA = Σ[(grade points + level bump) × credits] ÷ Σcredits
The unweighted GPA runs the same math with every bump set to zero. Credits matter more than people expect: a year-long 1.0-credit course moves your GPA twice as much as a 0.5-credit semester class.
Enter each course with its grade, level, and credit weight. Use half credits for semester courses at schools that count a full year as 1.0. The calculator updates as you type and shows both GPAs together, because the gap between them is itself information: a big gap means you've leaned into weighted coursework, a small one means you haven't.
Say your semester looks like this: an A in AP Calculus BC (5.0), a B+ in AP US History (4.3), an A in Honors English (4.5), a B in Honors Chemistry (3.5), an A in Spanish 3 (4.0), and a B in a half-credit US Government course (3.0). Quality points: 5.0 + 4.3 + 4.5 + 3.5 + 4.0 + 1.5 = 22.8 across 5.5 credits. That's a weighted GPA of 22.8 ÷ 5.5 = 4.15. Strip the bumps and the same transcript averages 19.8 ÷ 5.5 = 3.60 unweighted. One semester of heavy AP loading moved the needle by more than half a point.
One caution before you quote these numbers anywhere: schools disagree on the details. Some cap weighted GPA at 5.0, some don't weight Fs, some give +0.5 for dual enrollment instead of +1.0, and a few use entirely different scales. This calculator follows the most common convention; your student handbook is the source of truth for yours.
Add a bump to the standard grade points for harder classes, then average by credits. The most common scheme adds 1.0 for each AP or IB course and 0.5 for each honors course, so an A in AP Calculus is worth 5.0 instead of 4.0. Weighted GPA equals the sum of (grade points + level bump) times credits, divided by total credits.
Unweighted GPA uses only the 4.0 scale, so course difficulty doesn't matter: an A in gym and an A in AP Physics both count as 4.0. Weighted GPA adds points for AP, IB and honors courses, pushing the scale toward 5.0. Two students with identical grades can hold the same unweighted GPA but very different weighted ones.
Context sets the bar, but rough lines: above 3.0 is the college-bound norm, 4.0 means straight Bs or better with a few weighted courses mixed in, and 4.3 or higher signals mostly As in AP and IB classes. At schools that cap at 5.0, anything above 4.5 puts you in the top tier of applicants.
Both, and many look at neither directly. Admissions offices receive your full transcript and lots of them recalculate GPA with their own formula, often ignoring weights entirely and instead checking how many honors and AP courses you took relative to what your school offered. The rigor pattern matters as much as either number.
At most US high schools it's 5.0: a straight-A student in all AP or IB courses. Some districts use 6.0 scales that weight even more aggressively, and a few cap weighted grades at a ceiling lower than 5.0. Your student handbook is the only definitive source for your school's scale.
Very often yes, many districts weight dual enrollment college courses the same +1.0 as AP and IB, but it's school-specific. Some weight it less, some not at all. Check the grading policy before assuming the bump, since it can move a semester GPA by a tenth or two.
