Weighted GPA Calculator
Mark which of your courses are AP, Honors or IB, and this calculator adds the standard extra grade point on top of the normal letter grade — so you can see your weighted GPA and your unweighted GPA side by side.

What a Weighted GPA Measures
A weighted GPA gives extra credit for course difficulty. An A in a standard class and an A in AP Calculus both look identical on an unweighted 4.0 scale, even though one carries a heavier workload. Weighting fixes that by adding a fixed bonus — almost always 1.0 grade point — to any class flagged as AP, IB or Honors before it's averaged in.
Tick the "AP/Hon/IB" box next to any qualifying course above and the calculator applies that bump automatically. Leave a course unticked and it's scored on the plain 4.0 scale, exactly like the standard GPA calculator.
How Weighted GPA Is Calculated
The mechanics are identical to an unweighted GPA — quality points divided by credit hours — with one extra step for flagged courses.
Four courses, two of them AP:
- AP Biology (4 credits, grade A): 4.0 + 1.0 weighted bump = 5.0 → 4 × 5.0 = 20.0 quality points
- AP English (3 credits, grade B+): 3.33 + 1.0 = 4.33 → 3 × 4.33 = 12.99 quality points
- Gym (1 credit, grade A, not weighted): 1 × 4.0 = 4.0 quality points
- Algebra II (3 credits, grade A-, not weighted): 3 × 3.67 = 11.01 quality points
Total: 11 credits, 47.99 weighted quality points. Weighted GPA = 47.99 ÷ 11 = 4.36. Run the same four courses with every box unticked and the unweighted GPA comes out to 3.68 — the gap is the entire point of weighting.
Which GPA Actually Matters?
Both, for different audiences. Your weighted GPA is what your high school uses for class rank, honor roll and graduation cords — it rewards you for choosing harder classes. Your unweighted GPA is the number most college admissions offices ask for on the application itself, because it lets them compare students from schools with wildly different weighting rules on equal footing.
Selective colleges usually go a step further and recompute a "college GPA" from your transcript using their own formula — often unweighted, and often counting only core academic subjects. That number isn't something a calculator can reproduce without knowing the specific college's rules, so treat the figures here as your reportable school GPA, not a guaranteed admissions number.
Frequently Asked Questions
How much does an AP or Honors class add to GPA?
Most US high schools add 1.0 grade point on a weighted scale, so an A in an AP class is worth 5.0 instead of 4.0. Some schools use a smaller 0.5 bump instead — check your school's profile if the number looks off.
Is a weighted or unweighted GPA better for college applications?
Most colleges that consider GPA recalculate it on their own scale, usually from your unweighted grades and course list, so neither number alone decides admission. Weighted GPA matters most for your school's own class rank and honors cords.
Can a weighted GPA go above 4.0?
Yes. A student taking mostly AP or IB classes with A grades can post a weighted GPA of 4.5, 5.0 or higher, while their unweighted GPA stays capped at 4.0.
How do I convert a weighted GPA back to unweighted?
There is no exact formula, because the conversion depends on knowing which specific courses were weighted. The only reliable way is to re-enter each course and grade without ticking the AP/Honors box — which is what this calculator's toggle is for.
