Calculate My Grade: Weighted Grades, Finals, and Class Scores
Learn how to calculate your grade from assignments, tests, weights, and final exam targets with clear formulas and examples.
Searching calculate my grade usually means you want to know your current class grade or what score you need on a final exam. The right formula depends on whether your class uses points, category weights, or a final exam weight.
Use our Grade Calculator to calculate it quickly.
Points-Based Grade
For a points-based class:
Grade = Points earned / Points possible x 100
Example:
You earned 420 points out of 500.
420 / 500 x 100 = 84%
Weighted Grade Formula
For weighted categories:
Final grade = Sum of (category average x category weight)
Example:
| Category | Average | Weight | Weighted Score |
|---|---|---|---|
| Homework | 90% | 20% | 18 |
| Quizzes | 80% | 30% | 24 |
| Exams | 85% | 50% | 42.5 |
Total = 18 + 24 + 42.5 = 84.5%
What Grade Do I Need on the Final?
Use this formula:
Needed final score = (Target grade - Current grade x Current weight) / Final weight
Example:
- Current grade: 82%
- Current coursework weight: 80%
- Final exam weight: 20%
- Target grade: 85%
(85 - 82 x 0.80) / 0.20 = 97
You need 97% on the final.
Common Mistakes
