How it works
Each grade is multiplied by its weight, the results are added up, and the total is divided by the sum of the weights. This is a weighted average. If your weights add up to 100%, the result is your grade in the course. Rows you leave empty are ignored.
The formula
Weighted grade = (grade₁ × weight₁ + grade₂ × weight₂ + …) ÷ (weight₁ + weight₂ + …)
Worked example
Exams: 88% (weight 50%). Homework: 92% (weight 30%). Projects: 75% (weight 20%).
- 88 × 50 = 4,400, 92 × 30 = 2,760, and 75 × 20 = 1,500. The sum is 8,660.
- The weights add up to 100.
- Weighted grade: 8,660 ÷ 100 = 86.6%, which is a B.
Frequently asked questions
What is a weighted grade?
A weighted grade is an average where some grades count more than others. For example, if exams are worth 50% of the course and homework 30%, a good exam grade moves your final grade more than a good homework grade.
What if my weights do not add up to 100%?
The calculator still averages the grades using the weights you entered, so the result is your grade on the work counted so far. It also shows the total weight and how much weight is still to come, which is useful in the middle of a course.
How do I enter several grades in the same category?
First find the average of that category (for example, all your homework), then enter it with the category weight. If the homework is worth 20% in total, enter one row with the homework average and a weight of 20.
Where do I find the weights?
In your syllabus or grading policy. Teachers usually list percentages such as "quizzes 20%, midterm 30%, final 50%".
