Calculate a weighted course grade
Enter each category or graded component as a percentage score and its percentage weight in the course. The calculator normalizes partial weights when they do not yet total 100%.

Formula and interpretation
How this calculation works
The calculator keeps the weighting visible so you can trace the result and compare it with the method in your syllabus, transcript or institutional policy.
Worked calculation
Example: exams, assignments and participation
Suppose exams are 50% at 84%, assignments are 35% at 92%, and participation is 15% at 100%. The weighted contributions are 42.0, 32.2 and 15.0. Together they produce an 89.2% course grade.
Before relying on the estimate
Check the rules behind your numbers
- Use category averages when the syllabus weights categories rather than individual tasks.
- Do not enter both a category and its assignments unless the course truly counts both.
- Check whether missing work is treated as zero or excluded until graded.
- Confirm whether the learning-management system normalizes weights.
- Treat the result as an estimate until every item and policy matches the gradebook.
Questions students ask
Free Weighted Grade Calculator FAQs
What if my weights do not total 100%?
The tool reports the entered total and normalizes the weighted average across those rows. That is useful for completed work but may differ from the full-course grade.
Should I enter every assignment?
Only if assignments themselves carry weights. If the syllabus weights categories, enter the category averages and category weights instead.
How are ungraded assignments handled?
Do not enter them unless you want to test a projected score. A blank future category should not be silently treated as zero.
Why is my LMS grade different?
The LMS may use points, drop rules, extra credit, category normalization or hidden items. Compare the result with the syllabus calculation method.
