Each item’s percentage (points earned ÷ points possible) counts in proportion to its weight. If the weights entered do not total 100, they are scaled so the result is still a percentage.

Also called: Weighted score calculator, Category grade calculator.

## Inputs
- Item 1 points earned (default 45; optional)
- Item 1 points possible (default 50; optional)
- Item 1 weight (unit %; default 20; optional)
- Item 2 points earned (default 34; optional)
- Item 2 points possible (default 40; optional)
- Item 2 weight (unit %; default 30; optional)
- Item 3 points earned (default 70; optional)
- Item 3 points possible (default 100; optional)
- Item 3 weight (unit %; default 50; optional)
- Item 4 points earned (default ; optional)
- Item 4 points possible (default ; optional)
- Item 4 weight (unit %; default ; optional)
- Item 5 points earned (default ; optional)
- Item 5 points possible (default ; optional)
- Item 5 weight (unit %; default ; optional)
- Item 6 points earned (default ; optional)
- Item 6 points possible (default ; optional)
- Item 6 weight (unit %; default ; optional)
- Item 7 points earned (default ; optional)
- Item 7 points possible (default ; optional)
- Item 7 weight (unit %; default ; optional)
- Item 8 points earned (default ; optional)
- Item 8 points possible (default ; optional)
- Item 8 weight (unit %; default ; optional)

## Results
- Weighted score
- Unweighted total-points score
- Weights entered
- Items counted

## Formula

```
Weighted score = Σ wᵢ × (eᵢ ÷ pᵢ) ÷ Σ wᵢ × 100;  Points score = Σ eᵢ ÷ Σ pᵢ × 100
```

Where:
- eᵢ: points earned on item i
- pᵢ: points possible on item i
- wᵢ: weight of item i

## Worked example
1. Item scores: 45/50 = 90%, 34/40 = 85%, 70/100 = 70%.
2. Weighted = 0.20 × 90 + 0.30 × 85 + 0.50 × 70 = 18 + 25.5 + 35 = 78.5%.
3. Total points = 149 ÷ 190 = 78.42% for comparison.

**Result:** With weights of 20%, 30% and 50%, these scores give a weighted 78.5% (78.42% on raw points).

## What the result means

When the weights match your syllabus, the weighted score is your course grade so far. The points score shows what a points-based teacher would record instead.

## Assumptions and limits
- Each row is one item or one category total with its syllabus weight.
- Dropped lowest scores, extra credit and curves are not applied.

## Questions

### My weights only add to 60% so far. Is that a problem?

No. The calculator scales by the weights entered, giving your grade on the work completed so far.

### Should I enter each homework or the category total?

Either. For category weights, enter the category’s total points earned and possible with the category weight.
