Weighted Grade Calculator: Complete Guide (2025)
Use our weighted grade calculator to determine your course grade when assignments have different importance (weights). Perfect for college syllabi with midterms (30%), finals (40%), homework (20%), etc.
What is a Weighted Grade?
In a weighted grading system, each assignment contributes a percentage of your final grade based on its weight. Unlike simple averages, a 100% on a 10% quiz affects your grade less than a 100% on a 40% exam.
How to Calculate Weighted Grade
Formula:
Weighted Grade = Σ(Score × Weight) / Total Weight
Example:
- Midterm: 85% × 30% = 25.5
- Final: 90% × 40% = 36.0
- Homework: 95% × 20% = 19.0
- Participation: 100% × 10% = 10.0
- Total = 90.5%
What Score Do I Need on the Final?
Formula:
Required Final Score = (Desired Grade − Current Weighted) / Final Weight
Example: Current = 78.5%, Final worth 30%, Want 85%:
- Required = (85 − 78.5) / 0.30 = 21.67% on final? Wait—no:
- Actually: Required = [(Desired × 100) − (Current × (100 − Final Weight))] / Final Weight
- = [(85 × 100) − (78.5 × 70)] / 30 = 100.5% (impossible)
Weighted vs Unweighted GPA
| Type | Description | Example |
|---|---|---|
| Weighted | Honors/AP get +0.5 or +1.0 | A in AP = 5.0 |
| Unweighted | All classes equal | A = 4.0 |
