Grade Weight Distribution Calculator
Normalize grade weights to 100%.
Enter raw category weights or points. The calculator automatically normalizes them to sum to 100%.

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%
About
The Grade Weight Distribution Calculator converts any set of grade weights into a normalized breakdown that totals 100%. Enter the weight for each category — homework, quizzes, midterms, finals — and the tool scales them proportionally if they don't already add up. This makes category distribution easy to understand at a glance and prepares the weights for use in a weighted grade calculation. Teachers use it to verify syllabi weighting, and students use it to see how large a role each component plays in the final course grade.
Frequently asked questions
Why normalize weights?
Some teachers define weights that don't total 100. Normalizing shows the effective share of each category and matches how a weighted grade calculator always works.
Does this change my grade?
It changes the weights, not scores. Once normalized, use the weights to compute the weighted average of your category scores.
