Weighted GPA Calculator
This weighted GPA calculator adds your school's bonus for honors, AP or IB classes to each grade's points before averaging, so harder classes count more.
5 classes = 4.10 weighted GPA
4.10
20.5 grade points ÷ 5 credits

Example default: North Carolina's weights, +0.5 for honors and +1.0 for AP or IB (change them to your school's). College Board's sample school profile adds a full point to both.
By default no bonus is added to an F. Change “Which grades get the bonus?” if your school does it differently.

The AP GPA scale with a +1.0 bonus
A +1.0 bonus for AP or IB classes, this calculator's example default and the point College Board's sample school profile adds, makes an A count 5.0, a B 4.0 and a C 3.0. Your school may use other weights; the chart below shows every grade at every level.

Good to know
- Weights differ by state and school: this page's example default adds 0.5 for honors and 1.0 for AP or IB, while College Board's sample school profile adds a full point to both. Set the bonus boxes to your school's policy before you compare numbers.
- Some colleges strip the bonus out or apply their own weights so applicants from different schools compare fairly. Keep both your weighted and unweighted GPA, and your grades by class, for applications.
Common questions
What is a weighted GPA?
A weighted GPA gives harder classes, such as AP and honors, more GPA points than the plain 4.0 scale before the grades are averaged. Your school or state sets the extra points, so check its policy.
How much extra do honors and AP classes add to a weighted GPA?
It depends on the school or state; College Board tells families to check their school's policy. Its sample school profile adds 1 point to both AP and honors classes, while this calculator's example default is +0.5 for honors and +1.0 for AP or IB.
What is the difference between weighted and unweighted GPA?
An unweighted GPA gives every class the same 4.0-scale points (A = 4, B = 3, C = 2, D = 1, F = 0), so it tops out at 4.0. A weighted GPA adds the class-level bonus first, so it can go above 4.0; this calculator shows both side by side.
Is weighted GPA out of 5?
Only where the school's weights make it so: with a +1.0 bonus, as in College Board's sample school profile and this calculator's default, an A in an AP or IB class counts 4.0 + 1.0 = 5.0, so straight A's in those classes average 5.0. A school with other weights has a different top.
Do colleges use my weighted GPA?
College Board says colleges may recalculate GPAs, and some adjust or remove AP and honors weighting so applicants from different schools compare fairly.

Starts at the example default weights (+0.5 honors, +1.0 AP or IB), with no bonus on an F as this calculator's default (no source states it). Your school may differ: change the bonus boxes or “Which grades get the bonus?” in the calculator and this chart follows.
| Grade | Regular | Honors | AP or IB |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F or E | 0.0 | 0.0 | 0.0 |

How it works
A weighted GPA adds a bonus to the grade points of harder classes, such as honors, AP or IB, before averaging. Your school or state sets the bonus; this calculator starts at +0.5 for honors and +1.0 for AP or IB, and every bonus is editable.
Weighted GPA = sum of ((grade points + level bonus) × credits) ÷ total credits
- Turn each grade into points on the 4.0 scale: A = 4, B = 3, C = 2, D = 1, F = 0.
- Add the bonus for the course level: your school's numbers, or the example default of +0.5 for honors and +1.0 for AP or IB.
- Multiply by credits, add up, and divide by the total credits.
- The unweighted GPA is the same average without any bonus.
Worked example: +0.5 for honors, +1.0 for AP or IB
- AP Biology, A: 4.0 + 1.0 = 5.0
- Honors English, B: 3.0 + 0.5 = 3.5
- Geometry (regular), A: 4.0
- (5.0 + 3.5 + 4.0) ÷ 3 = 4.1667
Weighted GPA = 4.17 (unweighted 3.67)

What this doesn't account for
- Your school's own weights or bonus rules beyond the boxes you set.
- Limits on how many weighted classes count (UC, for one, caps its honors points).
- A different base scale or plus and minus grades: the base points are fixed at A = 4, B = 3, C = 2, D = 1 and F = 0.
- How a college may recalculate or remove the weighting.
