Weighted Grade Calculator
Enter each category grade and how much that category is worth. The weights should add up to 100.
How to use this calculator
Use this calculator to estimate an overall grade when different categories have different weights. Enter each category name, the score for that category, and how much that category counts toward the final grade.
Example
If tests are worth 40%, homework is worth 30%, quizzes are worth 20%, and participation is worth 10%, the calculator combines those category scores based on their weights to estimate the overall grade.
Common mistakes to avoid
- Make sure the category weights add up to 100%.
- Do not enter the same category twice unless your class separates it that way.
- Use the correct score for each category, not just one assignment score.
Weighted grades can vary by teacher or school. Always check the class grading policy to make sure the category weights match the course rules.
Who this tool helps
This calculator is useful for students, parents, and teachers in classes where tests, homework, quizzes, projects, or participation count for different percentages of the final grade.
When to use this tool
Use it when the class uses category weights instead of treating every point or grading period equally. Check the syllabus or grading policy before entering the weights.
Frequently asked questions
Do the category weights need to total 100%?
For a complete overall-grade estimate, the class category weights should normally add up to 100%.
Should I enter one assignment or the category average?
Enter the current average for each category unless your class grading policy says otherwise.
Is this the same as a weighted GPA calculator?
No. This tool combines weighted course categories; GPA uses grade points and, in some schools, course credits or advanced-course rules.
