Final weighted grade
Frequently asked questions
How is my final grade calculated?
Your final grade is the sum of each category's score multiplied by its weight (score times weight divided by 100), added across every row. This matches how most syllabi define weighted grades.
What if my weights don't add up to 100%?
The calculator still computes a result, but the weight remaining indicator turns red as a warning. Most grading schemes are only accurate when weights total exactly 100%, so double-check your syllabus.
Is my grade data saved anywhere?
Your categories, scores, and weights are saved to your browser's local storage only, so they'll still be there next time you open this page on the same device. Nothing is sent to a server.
