Weighted Grade Calculator

How to use the Weighted Grade Calculator

Use this when different parts of a class contribute different percentages to the final grade. Add each score and its weight to calculate the weighted average.

Model a grade made of named categories such as homework, quizzes, labs, and exams. The calculator is designed for category-based syllabi where each average contributes a fixed share of the course.

Fieldlet performs the calculation locally. Compare important academic results with the grading policy published by the relevant instructor or institution.

1. Each score is multiplied by its percentage weight.
2. The weighted points are added together.
3. If the entered weights total less than or more than 100%, Fieldlet also shows the normalized current average across the weights entered.

Worked examples

How the result is produced

A category's contribution is its average multiplied by its share of the course. Fieldlet totals the contributions and normalizes by the entered weights when they do not yet add to 100%.

• Use category averages, not category point totals
• Check that the same assignment is represented in only one category
• Use decimal scores only if the gradebook reports that precision

Limitations and common mistakes

• This model does not automatically drop a lowest score within a category.
• Extra-credit categories can follow rules that a simple weighted average cannot infer.
