How it works
Each category contributes its average times its fraction of the course. Missing categories should be omitted or weighted zero explicitly.
Formula
Overall = Σ (category average × category weight) with weights summing to 1
How to use Weighted Grade Calculator
- Add a category name, its average score, and weight percent.
- Ensure category weights sum to 100% (or let the tool normalize).
- Review the weighted total and adjust what-if scores.
- Pair with the final grade calculator for end-of-term planning.
Worked examples
Concrete numbers and cases you can check against the tool above.
Exams 50%, homework 30%, final 20%
Exam average 88, homework 92, final 85 → overall 0.5×88 + 0.3×92 + 0.2×85 = 89.0%.
When to use Weighted Grade Calculator
Syllabi rarely give equal weight to every score. This calculator mirrors how LMS systems compute totals so you can track your standing before grades post.
Common use cases
- Track a semester where exams are 60% and homework 40%.
- See how one bad quiz affects the total when quizzes are 10%.
- Rebuild your average after a dropped lowest score manually.
Inputs and outputs
- Category weights in percent
- Scores as percentages or points converted to percent

Frequently asked questions
- What if weights do not add to 100%?
- Some tools warn you; others normalize. Fix weights to match your syllabus for accuracy.
- Can I enter letter grades?
- Convert letters to midpoints (e.g. B = 85%) unless the tool maps letters for you.
- How is this different from GPA?
- This page is one course’s percentage. GPA blends multiple courses with credit hours.
