What is price gap?
The percentage difference between the price of one product or brand and a comparable alternative, such as branded versus private label.
Definition
A price gap compares like-for-like products: a brand against private label, a brand against its closest competitor, or the same product at two retailers. It is usually expressed as a percentage premium or discount.
How Data Purl measures it
Data Purl compares prices within the same category, normalized to price per unit where pack sizes differ, so a larger pack is not mistaken for a more expensive product.
Why it matters
A widening gap between a brand and private label can precede share loss. Gaps between retailers on the same product show who is leading or following on price.
