How to calculate a weighted grade
- Add each assignment, exam, or category and its percentage score.
- Enter how much each item contributes to the course grade.
- Review the weighted percentage, letter estimate, and total weight.
The calculation is Σ(score × weight) ÷ Σ(weight). For example, scores of 85, 78, and 92 weighted at 30%, 30%, and 40% produce 85.7%. Letter grades use common US boundaries, which may differ from your school.
FAQ
How is the weighted grade calculated?
Each score is multiplied by its weight. Those weighted points are added and divided by the total entered weight, so partial course weights are normalized.
Do my weights need to total 100%?
A complete course breakdown normally totals 100%. The calculator can still estimate a grade from partial weights and clearly reports the total entered.
Which letter-grade scale is used?
The estimate uses A at 90%, B at 80%, C at 70%, D at 60%, and F below 60%. Use your institution’s boundaries if they differ.
Can I calculate grades by category?
Yes. Enter category averages such as Assignments, Midterm, and Final with their course weights, or enter individually weighted assessments.
Is my grade information saved?
No. Calculation happens in your browser and the entered rows disappear when the page is reloaded.
