Formula: Normalized share = (Category weight ÷ Total weight) × 100. Rounded to guarantee an exact 100.0% sum.
How to use
- 1Enter the weight for each grading category — homework, quizzes, midterm, final, and so on.
- 2Weights may be entered as whole numbers or percentages.
- 3The calculator normalizes any total to 100% so you can see each category's share of the final grade.
Formula
Normalized weight = category weight ÷ Σ weights × 100When weights don't sum to 100, the calculator scales each category proportionally so they always total 100%. The same normalization a weighted grade calculator applies internally when you record scores.
Examples
Homework 30, Quizzes 20, Midterm 20, Final 45
Total = 115. Homework = 30 ÷ 115 × 100 ≈ 26.1%; Final = 45 ÷ 115 ≈ 39.1%.
Final carries 39.1%
