Do the weights need to add up to 100%?
For a full course estimate, yes. If they do not total 100%, the calculator can still show a partial weighted result, but the estimate should be treated carefully.

What this tool is
The Weighted Grade Calculator estimates a course grade by multiplying each category score by that category's course weight.
Tool overview
Weighted grading is common when homework, quizzes, exams, projects, and participation do not count equally. This calculator keeps the model visible so students can understand how each category affects the estimate.
Who it is for
- Students in courses with weighted grading categories
- Learners checking a gradebook against a syllabus
- Students comparing which category has the largest remaining impact
Problems it helps solve
- Combining several category scores into one weighted course estimate
- Checking whether category weights total 100%
- Seeing which category has more influence on the course result
Main features
- Four weighted category rows
- Weighted course grade estimate
- Unused row handling
- Browser-based calculation
- Plain-English formula explanation
How to use it
- Enter a category score, such as homework or exams.
- Enter the weight that category has in the course.
- Repeat for each category you want to include.
- Check the weighted estimate and whether the entered weights total 100%.
Example use case
Combining homework, quizzes, exams, and project scores
A course might count assignments as 30%, quizzes as 20%, exams as 40%, and a project as 10%. If the scores are 88, 82, 84, and 95, the weighted grade estimate is 85.9%.
- Enter 88 with a 30% weight.
- Enter 82 with a 20% weight.
- Enter 84 with a 40% weight.
- Enter 95 with a 10% weight and check the weighted result.
Limitations
- The calculator assumes category weights are percentage-based and transparent.
- Dropped assignments, grading curves, extra credit, minimum category rules, and instructor overrides are not modeled.
- The result is a planning estimate, not an official gradebook value.
Privacy note
The weighted grade calculator runs in the browser and does not require login. Normal grade inputs are used locally for calculation.
FAQ
Can this handle dropped assignments?
No. A basic weighted grade calculator assumes the category score you enter already reflects any dropped assignments or gradebook rules.
Is this the same as GPA?
No. Weighted course grade estimates a percentage course result. GPA depends on school-specific grade points and credit rules.
