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.
