Weighted GPA Calculator
Add course-level bonuses for honors, AP, IB and dual enrollment classes, and compare your weighted GPA against the unweighted one. The bonus values are yours to set.

The difference is the whole point of a weighted GPA: it is how much credit your school gives you for taking harder courses. A large gap means a demanding schedule — but remember many colleges recalculate GPAs unweighted, so both numbers matter.

How to use this calculator
- Set the bonus points your school awards for each course level. If you do not know, start with the defaults and ask your counsellor.
- Add each course with its credits, grade and level.
- Weighted and unweighted GPAs appear side by side, with the difference between them.
How weighting works
A weighted GPA adds bonus points to the grade points of harder courses before averaging. An A in an AP class worth a 1.0 bonus counts as 5.0 rather than 4.0, so a weighted GPA can exceed 4.0.
The bonus is added to the grade points, not multiplied, and it applies to every grade in that course — a C in an AP class gets the same bonus an A does.
A worked example
Three courses, using the common bonuses of +1.0 for AP and +0.5 for honors:
| Course | Credits | Level | Grade | Points + bonus | Quality points |
|---|---|---|---|---|---|
| AP Biology | 4 | AP | A | 4.0 + 1.0 = 5.0 | 20.0 |
| Honors English | 3 | Honors | B+ | 3.3 + 0.5 = 3.8 | 11.4 |
| Algebra II | 3 | Regular | A- | 3.7 + 0.0 = 3.7 | 11.1 |
| Total | 10 | — | — | — | 42.5 |
Weighted GPA: 42.5 ÷ 10 = 4.25.
Without the bonuses, the same grades give 16.0 + 9.9 + 11.1 = 37.0 quality points, so the unweighted GPA is 37.0 ÷ 10 = 3.70. The difference of 0.55 is what the weighting is worth on this schedule.
Common weighting schemes
There is no national standard. These are patterns you will see, not rules:
| Scheme | Honors | AP / IB | Maximum GPA |
|---|---|---|---|
| Half and full point | +0.5 | +1.0 | 5.0 |
| Full point for both | +1.0 | +1.0 | 5.0 |
| Third-point steps | +0.33 | +0.67 | 4.67 |
| AP only | +0.0 | +1.0 | 5.0 |
Some schools also cap the weighted GPA, or weight only core academic subjects. Your student handbook is the place to check.
Important notes and limitations
Weighted GPAs are not comparable between schools
A 4.4 at a school that adds a full point for honors is not the same achievement as a 4.4 where only AP courses are weighted. This is exactly why many colleges recalculate applicants' GPAs themselves, often unweighted.
- Dual enrollment is weighted at some schools and not others — set its bonus to 0 if yours does not weight it.
- A bonus usually applies to any passing grade in the course, though a few schools withhold it below a C.
- Weighted GPA is a school-specific figure. For applications, know your unweighted number too — the Unweighted GPA Calculator gives it directly.
Frequently asked questions
What is the highest weighted GPA possible?
It depends entirely on your school's bonuses. With +1.0 for AP courses on a 4.0 scale, the ceiling is 5.0 — and only for a student taking nothing but AP classes and earning straight As. With +0.5 bonuses the ceiling is 4.5.
Is a 4.5 weighted GPA good?
It usually indicates strong grades in a demanding schedule, but the number alone is not comparable between schools. Admissions offices read it alongside your transcript and your school's profile, which explains its weighting policy.
Does a bad grade in an AP class still get the bonus?
At most schools, yes — the bonus attaches to the course, not the grade. A C in an AP class worth +1.0 counts as 3.0 rather than 2.0. A minority of schools withhold the bonus below a certain grade, so check yours.
Why is my weighted GPA lower than I expected?
The most common reasons are regular courses diluting the average, a school scheme that weights less generously than you assumed, or weighting that applies only to core subjects. Set the bonus fields above to what your school actually does and the numbers should line up.
Should I take an easier class to protect my GPA?
That is a real trade-off and the arithmetic only tells you half of it. A weighted GPA rewards rigour, and colleges assess course difficulty separately, but a grade you cannot sustain helps nobody. Talk it through with your counsellor rather than deciding on a number.
