Weighted GPA Calculator
Enter your classes, grades, and course levels — Honors and AP/IB classes get extra weight, just like most high school transcripts calculate them.
Weighted GPA adds +0.5 for Honors and +1.0 for AP/IB classes to each course’s grade point before averaging — this matches how most U.S. high schools calculate it, though some schools use slightly different bonus values.
How Weighted GPA Is Calculated
An unweighted GPA treats every class the same — an A in gym counts exactly as much as an A in AP Calculus. Weighted GPA fixes that by adding bonus points for harder courses: typically +0.5 for Honors classes and +1.0 for AP or IB classes, on top of the standard 4.0 grade-point scale. That means an A in an AP class can be worth 5.0 instead of 4.0.
To calculate it, each course’s grade is converted to a grade point (A=4, B=3, and so on), the course-level bonus is added if applicable, and the result is multiplied by that course’s credit hours. All of those are summed and divided by total credit hours to get the final weighted GPA.
One thing to double check with your school: bonus values aren’t universal. Most U.S. high schools use +0.5 for Honors and +1.0 for AP/IB, but some use +1.0 for both, and a handful cap weighted GPA at 5.0 regardless of how many advanced classes you take. This calculator uses the most common +0.5 / +1.0 system with no cap.
Weighted GPA Bonus Scale
| Course Level | Bonus Added | Example: A grade |
|---|---|---|
| Regular | +0.0 | 4.0 |
| Honors | +0.5 | 4.5 |
| AP / IB | +1.0 | 5.0 |
Frequently Asked Questions
Does every high school weight GPA the same way?
No — bonus values vary by school and district. The +0.5 Honors / +1.0 AP-IB system used here is the most common, but check your school’s counseling office or transcript key for the exact scale they use.
Is weighted or unweighted GPA more important for college applications?
Most colleges recalculate GPA using their own formula anyway, often looking closely at course rigor separately from the raw number. Both figures matter — weighted shows you took harder classes, unweighted shows raw grade performance.
Can a weighted GPA go above 4.0?
Yes — that’s the point of weighting. A student who takes several AP or IB classes and earns A’s can end up with a weighted GPA of 4.3, 4.5, or higher, depending on their school’s scale.
What if my school uses plus/minus grades differently?
The grade-point values here (A=4.0, A-=3.7, B+=3.3, etc.) follow the standard U.S. scale used by most high schools and colleges. If your school rounds differently, your actual transcript GPA may be slightly different from this estimate.
