Compare two products by unit price.
Compare two products by price per unit instead of sticker price. Enter price and quantity for A and B to see which is cheaper per gram, item, milliliter or any other shared unit.
Do not enter A in grams and B in kilograms without converting first. The tool assumes both quantity values are directly comparable.
A smaller pack can cost less at checkout but more for each gram or item. Dividing price by quantity puts differently sized packs on the same scale.
Compare grams with grams, milliliters with milliliters, or items with items. For 900 g versus 1.2 kg, convert one side so the quantities are 900 and 1200 in grams.
The result does not account for ingredients, performance, shipping, loyalty points or expiry dates. It answers only the price-per-quantity question.
A lower unit price can still waste money if the extra quantity expires or is never used. For perishable goods, combine unit price with realistic consumption.
