Weighted GPA Calculator
Add your classes, pick input type (percentage, letter grade, or points), choose Regular/Honors/AP, and get Weighted GPA instantly. Works with credit hours.
Scale controls how letter/percentage convert into grade points.
Weighted GPA adds a bonus to grade points for harder classes.
No need to convert yourself. Pick how you want to enter grades.
- If your school caps weighted GPA, you can switch to custom table and bonuses.
- Credits can be 0.5, 1, 3, 5 etc. Calculator uses credit-weighted average.
- If you enter points directly, weighting still applies based on level (unless “No weighting”).
How Weighted GPA Calculator Works
Pick your GPA scale (4.0/5.0/custom), choose course weighting, and select how you’ll enter grades: percentage, letter, or points.
Add your classes and enter grade + credits. Then choose the level: Regular, Honors, or AP/IB.
Hit Calculate. We convert your input to points, apply weighting bonus for Honors/AP, then compute: (points × credits) ÷ total credits.
Why Use This Weighted GPA Calculator?
Add classes and calculate your weighted GPA in seconds. No messy spreadsheets.
Enter grades as percentage, letter, or points. We convert automatically.
Regular, Honors, and AP/IB supported. Bonus points apply to reflect course difficulty.
Save your classes, copy a share link, or download CSV for your counselor or parents.
How to Use the Weighted GPA Calculator
This calculator helps you compute your high school weighted GPA using your classes, grades, course level, and credit hours. It matches how most schools calculate GPA when Honors or AP/IB courses carry extra weight.
What Is a Weighted GPA?
A weighted GPA increases your grade points for harder classes.
Regular classes keep the base points, while Honors and AP/IB add a bonus.
Typical setup:
Regular: no bonus
Honors: +0.5
AP/IB: +1.0
So an A in AP becomes higher than an A in Regular, because the course is more difficult.
How the Calculator Converts Your Grades
You can enter grades in three ways, and the calculator converts them automatically:
Percentage (example: 92)
Letter grade (A-, B+, etc.)
Grade points (3.7, 4.0, etc.)
This removes manual conversion errors that many students face.
How Weighted GPA Is Calculated
The calculator follows the standard school formula:
Weighted GPA = (Grade Points × Credits) ÷ Total Credits
Then it applies the course bonus:
Honors → adds Honors bonus
AP/IB → adds AP bonus
Example:
AP Biology: A (4.0) + 1.0 bonus = 5.0, credits 1
English: B (3.0), credits 1
Weighted GPA = (5.0 + 3.0) ÷ 2 = 4.0
Why Credit Hours Matter
Credit hours control how much each class affects GPA.
A 5-credit class impacts GPA more
A 0.5-credit elective impacts less
That’s why accurate GPA always uses credits, not simple averages.
When to Use Weighted GPA
Students usually need weighted GPA for:
High school transcripts
College admissions comparison
Scholarship applications
Class rank evaluation
Colleges often look at both weighted and course rigor together.
Tips to Improve Your Weighted GPA
Take Honors or AP in strong subjects
Avoid low grades in weighted classes
Balance rigor with realistic performance

Key Takeaway
Weighted GPA rewards academic difficulty.
Harder classes can raise GPA more than regular ones, but only if you maintain solid grades.
FAQs
Quick answers to common questions about weighted GPA calculation and course weighting.
1. What is a weighted GPA?
A weighted GPA gives extra grade points for harder courses like Honors and AP/IB. Regular classes use base points (like 4.0 for A), while weighted classes add a bonus (for example +0.5 or +1.0).
2. How is weighted GPA calculated?
Weighted GPA is calculated using credit hours and course level: (grade points + course bonus) × credits ÷ total credits. Honors and AP classes increase grade points before averaging.
3. How much does Honors or AP increase GPA?
Most schools add about +0.5 for Honors and +1.0 for AP/IB courses. However, weighting varies by school, which is why the calculator allows custom weighting values.
4. Can I enter percentage or letter grades?
Yes. You can enter grades as percentage, letter grade, or grade points. The calculator converts them into GPA points automatically before applying course weighting.
5. Do credit hours affect weighted GPA?
Yes. Credit hours determine how much each class impacts GPA. A higher-credit course influences GPA more than a low-credit elective because the formula uses credit-weighted averaging.
6. Is weighted GPA higher than regular GPA?
Usually yes. If you take Honors or AP courses and earn good grades, weighted GPA becomes higher than unweighted GPA because of added difficulty bonuses.
