About BeautyByRatio
BeautyByRatio is a beauty and cosmetics price comparison tool. We score every makeup and skincare product by real price per unit (gram, ml, oz) across top retailers such as Ulta and Target, and flag ingredient cleanliness so shoppers can see actual value beyond the shelf price.
How we calculate cost per gram
We take the current retail price and divide it by the product's net weight in grams, giving a standardised unit cost that makes cross-product comparison fair regardless of package size.
What makes a beauty product clean
We score cleanliness based on the presence or absence of commonly flagged ingredients — parabens, sulphates, synthetic fragrances, phthalates, and other additives linked to skin irritation or broader health concerns.
Is BeautyByRatio free to use?
Yes. Comparing products, viewing ingredient breakdowns, and accessing price-per-gram data is completely free.
