Weighted Ranking

Select a category and products, set weights, then click "Calculate Weighted Ranking".

Scores are 0–100: each dimension is min–max normalized across the compared set (cost-type dimensions like price / MOQ / lead time are inverted), then weighted-summed by your weights. All computation runs in your browser — transparent and reproducible.

Why weighted comparison?

Two buyers can look at the same catalogue and reach opposite conclusions, because they value different things. A warehouse operator cares about lifetime and lead time; a retailer cares about CRI and MOQ. Weighting the criteria yourself — and seeing the arithmetic — is the difference between a ranking you can defend and one you cannot.
