How to Calculate Weighted GPA
Complete step-by-step guide to calculating weighted GPA for high school students
Quick Answer:
Weighted GPA: give each course a point value (A = 4.0 regular or 5.0 for AP/IB/honors), multiply by credit hours, add up, divide by total credits. This guide walks you through it step-by-step with examples.
What is Weighted GPA?
Weighted GPA gives extra points for advanced courses like AP, IB, and honors classes. This system rewards students for taking more challenging coursework and provides a more accurate representation of academic achievement.
Key Differences:
- Unweighted GPA: Uses standard 4.0 scale for all courses
- Weighted GPA: Gives extra points for advanced courses (up to 5.0 scale)
- Purpose: Better reflects course difficulty and student effort
Step-by-Step Weighted GPA Calculation
Step 1: Identify Course Types
Regular Courses
Standard 4.0 scale (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0)
Advanced Courses
Weighted 5.0 scale (A=5.0, B=4.0, C=3.0, D=2.0, F=0.0)
Step 2: Convert Letter Grades to Points
| Letter Grade | Regular Points | Weighted Points |
|---|---|---|
| A+ | 4.0 | 5.0 |
| A | 4.0 | 5.0 |
| A- | 3.7 | 4.7 |
| B+ | 3.3 | 4.3 |
| B | 3.0 | 4.0 |
Step 3: Calculate Weighted GPA
Formula:
Weighted GPA = (Sum of Grade Points × Credit Hours) ÷ Total Credit Hours
Example Weighted GPA Calculation
Sample Student Grades:
| Course | Type | Grade | Points | Credits | Total Points |
|---|---|---|---|---|---|
| AP Calculus | Advanced | A | 5.0 | 1.0 | 5.0 |
| English | Regular | B+ | 3.3 | 1.0 | 3.3 |
| AP History | Advanced | A- | 4.7 | 1.0 | 4.7 |
| Chemistry | Regular | B | 3.0 | 1.0 | 3.0 |
Calculation:
Total Points: 5.0 + 3.3 + 4.7 + 3.0 = 16.0
Total Credits: 4.0
Weighted GPA: 16.0 ÷ 4.0 = 4.0

Frequently Asked Questions
What's the difference between weighted and unweighted GPA?
Unweighted GPA uses a standard 4.0 scale for all courses, while weighted GPA gives extra points for advanced courses like AP, IB, and honors classes, often using a 5.0 scale.
Do colleges prefer weighted or unweighted GPA?
Most colleges consider both, but they often recalculate GPA using their own standards. Weighted GPA shows course rigor, while unweighted GPA shows raw academic performance.
How do I know if my school uses weighted GPA?
Check your school's grading policy or ask your guidance counselor. Most high schools that offer AP, IB, or honors courses use weighted GPA systems.
How much do AP and honors courses add to my GPA?
AP and IB usually add 1.0 point (A = 5.0); honors often add 0.5 (A = 4.5). This varies by school, so check your district's policy.
Can I calculate weighted GPA without a calculator?
Yes. Multiply each letter grade's points by the course credit (or weight), add them up, then divide by total credits. Our calculator does this instantly.
