High School GPA Calculator
Weighted and unweighted high-school GPA side by side, with the AP, IB, and honors bumps applied the way American high schools apply them. Colleges ask for different versions of this number, so the calculator shows both rather than picking one.
Works offline — your inputs never leave this device. How that works
This one uses the US 4.0 scale. The weighted-GPA convention — a 5.0 ceiling for advanced courses — is specific to American high schools, so there is no scale picker here rather than a conversion that would be made up.
| Course | Grade | Credits | Level | Remove |
|---|---|---|---|---|
Letters from A+ to F. A failing grade never receives a bump.
4.07 weighted
Across 3 credits. Advanced-course bumps add 0.50.
🔢 Show the math
- Convert each letter to grade points on the 4.0 scale: 4, 3, 3.7.
- Add the bump for advanced courses (honors +0.5, AP +1, IB +1); a failing grade gets no bump.
- Multiply by credits and total: 12.2 quality points across 3 credits.
- 12.2 ÷ 3 = 4.07.
Grading scales vary by institution — your school's own table and syllabus govern. Conversions shown here follow common published conventions.

What it is
This calculates a high-school GPA both ways at once: unweighted on the plain 4.0 scale, and weighted with the extra points American high schools award for AP, IB, and honors courses.
How it works
Each letter converts to grade points on the 4.0 scale. In weighted mode, honors courses receive an extra half point and AP or IB courses a full point, except where the grade is failing. Points are then multiplied by credits and divided by total credits.
Getting the most from it
- Enter every course from the transcript, including the ones outside your strongest subjects — leaving out a weak grade produces a number nobody else will recognise.
- Set each course's level accurately, since the bump is the whole difference between the two figures.
- Use your school's credit values rather than assuming one credit per course; year-long and semester courses often differ.
- Compare the weighted and unweighted results, because different applications ask for different ones.
Reading your result
The headline follows the mode you selected, and both figures are listed underneath. The gap between them is what your course load is worth: a wide gap means a demanding schedule, and it is a gap admissions offices read directly.
What it can't tell you
Weighting conventions vary between school districts — some award different bumps, some cap the weighted GPA, and many colleges recalculate their own from the transcript using only academic courses. This is your school's arithmetic, not an admissions office's.
Frequently asked questions
What is the difference between weighted and unweighted GPA?
Unweighted treats every course the same on a 4.0 scale. Weighted adds points for harder courses — commonly half a point for honors and a full point for AP or IB — so it can exceed 4.0. A 4.3 weighted GPA is ordinary; a 4.3 unweighted one is not possible.
How much does one AP class raise my GPA?
Less than people expect, because the bump is divided across all your credits. One AP course among eight raises a weighted GPA by roughly an eighth of a point, and the calculator shows the exact difference between your weighted and unweighted figures.
Which GPA do colleges look at?
Many recalculate their own from your transcript, using only academic courses and often their own weighting. Report the figure your school reports, keep both, and treat neither as the number an admissions office will ultimately use.
Does a failing grade in an AP class still get the bump?
No. The convention is that a failing grade earns no weight bonus, since the bump rewards completing harder material rather than enrolling in it. The calculator applies that rule, so an F stays a zero regardless of course level.
