How weighted grades work

A weighted course grade gives different parts of your class different importance. A 20% homework category affects the final course grade less than a 50% exam category, even when the scores are identical.

Formula

Weighted Grade = Σ(Category Score × Category Weight) ÷ Σ(Category Weight)

Example

Suppose homework is 20% at 90%, quizzes are 30% at 80%, and exams are 50% at 88%. The weighted grade is the sum of each score multiplied by its weight.

Total weight matters

For a complete weighted course calculation, the category weights normally add to 100%. Some gradebooks intentionally use a different total during an interim calculation, so the tool also shows your current weight total.

Frequently asked questions

What is a weighted grade?

A weighted grade combines category scores — like homework, quizzes, and exams — using the percentage weight your syllabus assigns to each category, instead of treating every assignment equally.

What if my category weights don't add up to 100%?

The calculator normalizes using only the weights you've entered and flags it, so you can still see a partial-gradebook estimate. For an official course grade, use the full set of category weights from your syllabus.

What's the difference between a weighted grade and a GPA?

A weighted grade is your percentage in one course, based on assignment categories. A GPA averages grades across multiple courses, usually weighted by credit hours rather than assignment categories.

Can I use this for college and high school classes?

Yes. Weighted grading by category (homework, quizzes, midterms, finals, participation) is common at both levels — enter the categories and weights from your specific syllabus.
