Weighted Grade Calculator

List each category — assignments, quizzes, projects, exams — with the grade you earned and the weight it carries. We compute the weighted course average.

CategoryGradeWeight

Grades and weights are in percent. Weights don't have to sum to 100 — we normalize what you enter.

Final88% · 40%

Examples

Homework 95% × 30%, Midterm 82% × 30%, Final 88% × 40%

= 88.30%

Quizzes 90% × 20%, Projects 84% × 35%, Exam 78% × 45%

= 82.50%

How it works

A weighted average multiplies each grade by its weight, sums the results, and divides by the total weight.

Weighted grade · Σ(gradei × weighti) ÷ Σ(weighti)

Frequently asked questions

A weighted grade is an average where each item counts proportionally to its assigned weight. A 100% on a 30%-weighted final affects your average more than a 100% on a 5%-weighted homework assignment.

Not for this calculator — we normalize the weights you enter, so a partial weighting still works (useful when you only care about the items you've completed so far).

Your syllabus is the source of truth. A typical breakdown might be 40% exams, 30% homework, 20% projects, 10% participation.

Yes — add it as a category with a weight that matches what your professor specified, or assign it a small weight (e.g., 2%) and a grade above 100%.
