Final Grade Calculator
Calculate Your Weighted Final Grade
Add grade categories with scores and weights to calculate a weighted final percentage. Weights can be any positive numbers — they are normalized automatically.
Weights are relative — enter any positive numbers. Final grade = sum(score × weight) ÷ sum(weights).
| Category | Score (0–100) | Weight | Remove |
|---|---|---|---|
| Category 1 | |||
| Category 2 |
Enter at least one score and weight to calculate your final grade.
How Weighted Grades Work
- 01
Add categories
Each row is an assignment, exam, or grade category.
- 02
Enter score (0–100)
The percentage score for that category.
- 03
Enter weight
How much that category counts toward the final grade. Weights are relative — 30 and 70 works the same as 3 and 7.
- 04
View weighted result
Final grade = sum(score × weight) ÷ sum(weights).
Examples
Two equal categories
Midterm 85% (weight 50) + Final 90% (weight 50) = 87.5% final.
Unequal weights
Homework 95% (weight 20) + Exam 80% (weight 80) = 83% final.
Three categories
Quizzes 88% (30) + Project 92% (30) + Final 78% (40) = 85.4% final.
