Step-by-Step: How to Calculate Your Final Grade
Your final grade depends on the weighted average of different components such as homework, quizzes, projects, midterms, and final exams.
Here’s how to do it step by step.
Step 1: Identify Each Category and Its Weight
Check your course syllabus or grading policy to find out how much each component counts toward your final grade.
Example weighting:
- Homework: 20%
- Quizzes: 10%
- Midterm: 30%
- Final Exam: 40%
Step 2: Find Your Average Score in Each Category
Let’s say your scores are:
- Homework: 90%
- Quizzes: 85%
- Midterm: 80%
- Final Exam: 88%
Step 3: Convert Percentages to Decimals
Before multiplying, convert each weight and grade to a decimal.
| Category | Grade | Weight | Decimal Conversion |
| Homework | 90% | 20% | 0.20 |
| Quizzes | 85% | 10% | 0.10 |
| Midterm | 80% | 30% | 0.30 |
| Final Exam | 88% | 40% | 0.40 |
Step 4: Multiply Each Grade by Its Weight
Now calculate each category’s weighted contribution:
| Category | Grade (Decimal) | Weight | Weighted Score |
| Homework | 0.90 | 0.20 | 0.18 |
| Quizzes | 0.85 | 0.10 | 0.085 |
| Midterm | 0.80 | 0.30 | 0.24 |
| Final Exam | 0.88 | 0.40 | 0.352 |
Step 5: Add All Weighted Scores
Add them up to find your final grade:
✅ Final Grade = 85.7% (B)
Your final class average is 85.7%, which usually corresponds to a B.

Why Weighted Grades Matter
Each category in your course doesn’t count equally. The weight determines its influence on your final average.
For example:
- Missing a homework worth 5% won’t drastically lower your grade.
- Failing a final exam worth 40% can significantly impact your final score.
That’s why it’s essential to know how much each assignment is worth and calculate your current standing regularly.
