About This Tool

Free weighted grade calculator — add each grading category (like Homework, Quizzes, Midterm, Final Exam), its weight as a percentage of your final grade, and your score in that category, and instantly get your overall weighted course grade. No sign-up, no upload, entirely browser-based. Most college and high school courses don't grade everything equally — a final exam might count for 40% while homework only counts for 10%. This tool handles that math automatically and warns you if your category weights don't add up to 100%.

How to Use

  1. 1

    Add each category

    Enter the name, weight percentage, and your score for each grading category (e.g. Homework 20%, Exams 50%, Final 30%).

  2. 2

    Check the weights total 100%

    The tool flags it if your entered weights don't add up to 100%.

  3. 3

    Read your overall grade

    See your final weighted percentage grade calculated instantly.

Frequently Asked Questions

What happens if my weights don't add up to 100%?+
The calculator still computes a result using the weights as entered, but shows a warning — double-check your syllabus, as most courses weight categories to total exactly 100%.
Can I add or remove categories?+
Yes, add as many grading categories as your course has, or remove ones you don't need.
How is a weighted grade different from a simple average?+
A simple average treats every item equally. A weighted grade multiplies each category's score by its assigned weight, so a category worth 40% affects your final grade four times as much as one worth 10%.
