Weighted Grade & Class Calculator
Determine your current grade and what you need on the final exam.
How to Use the Class Grade Calculator
This weighted grade calculator helps you stay on top of your academic performance by calculating your current standing based on different syllabus categories. To get an accurate result, follow these steps:
- Enter Scores: Input the percentage you have earned in each category (e.g., if you have a 90% average on homework, enter 90).
- Assign Weights: Enter the percentage weight for each category as defined in your course syllabus. The total weight (including the final) should ideally equal 100%.
- Set Your Target: If you want to know what you need on your final exam, enter your desired final grade for the semester and the weight of the final exam.
Understanding Weighted Grades
In most college and high school courses, not all assignments are created equal. A "weighted grade" means that certain categories, like a final project or midterm, contribute more to your final GPA than others, like daily attendance or short quizzes.
The formula for a weighted grade is:
Grade = (w1 × g1 + w2 × g2 + … + wn × gn) / (w1 + w2 + … + wn)
Where w is the weight and g is the grade earned in that category.
Example Calculation
Imagine your class is broken down into three parts:
- Homework: 40% of grade (You scored 95%)
- Midterm: 30% of grade (You scored 80%)
- Final Exam: 30% of grade (Not yet taken)
Your current weighted score is (95 * 0.40) + (80 * 0.30) = 38 + 24 = 62%. However, since you've only completed 70% of the course weight, your current average is 62 / 70 = 88.57%.
If you want an "A" (90%) in the class, you would calculate: (90 – 62) / 0.30 = 93.33%. You need a 93.33% on your final exam to reach your goal.
