Overall weighted percentage
AI explanation
Formula
Overall % = (sum of each component's score × its weight) ÷ (sum of all weights)Worked example
4 components: scores 85, 78, 92, 88 weighted 20%, 20%, 25%, 35%
| Field | Value |
|---|---|
| Component scores (%) | 85, 78, 92, 88 |
| Component weights (%) | 20, 20, 25, 35 |
| Overall weighted percentage | 86.4 |
| Letter grade | B |
Assumptions
- The scores and weights lists must have the same number of entries, in matching order.
- Weights need not sum to exactly 100 — they're normalized by their own total.
- Letter grade uses a common absolute scale (A≥90, B≥80, C≥70, D≥60, else F) — actual grading scales vary by institution.
Frequently asked questions
How is this different from the Grade Calculator?
The Grade Calculator handles exactly 3 fixed components (assignment, midterm, final) — this one supports any number of components with any weights, useful for courses with quizzes, labs, projects, and more.
What if my weights don't add up to 100%?
That's fine — the formula normalizes by the total weight you entered, so relative weights (e.g. 2, 2, 3) work just as well as percentages that sum to 100.
Can I use this for GPA too?
No — GPA weights grade points by credit hours across whole courses; this calculates one course's overall grade from its internal components. Use the GPA Calculator for that.
