Find which size or pack is the better deal

Unit price comparator

Compare two products by unit price to find which size, pack, or brand is actually the better value.

Formula

unit price = price ÷ quantity — the lower unit price is the better value

Assumptions

• Both quantities must be entered in the same unit (e.g. both grams, or both milliliters) for the comparison to be valid.

Frequently asked questions

Why isn't the bigger pack always the better deal?
Retailers don't always price larger packs proportionally cheaper — sometimes a promotion on the smaller size, or a premium on the largest size, flips the usual assumption that buying bigger saves money. Comparing unit price directly avoids guessing.

What if the products are in different units (e.g. grams vs. ounces)?
Convert one to match the other first — use the Weight converter or another unit converter, then enter both quantities in the same unit here.
