Own-brand products sit beside national brands at lower prices, and the gap is not explained by lower quality. The cost structures behind the two are fundamentally different.
The distribution cost is already paid
A branded manufacturer has to earn its place on the shelf, which involves trade terms, promotional funding and listing negotiations with every retailer it wants to sell through.
The retailer's own product faces none of that. Its route to the customer is the retailer's own estate, and the decision to stock it is made internally at no commercial cost.
That difference alone accounts for a meaningful share of the price gap, before any consideration of manufacturing, packaging or the specification of what is inside.
Demand creation is borrowed
National brands invest continuously in advertising to create demand that exists before the shopper enters the store. That expenditure is recovered in the price of every unit sold.
Own-brand products generally rely on being present at the moment of choice, adjacent to a product the shopper already came in wanting. The demand was created by somebody else.
This is the structural asymmetry: the branded product funds awareness for the whole category, and the own-brand alternative benefits from it at the shelf without contributing anything.
Manufacturing is often shared
Own-brand goods are frequently produced by manufacturers who also make branded products, sometimes on the same production lines and to closely comparable specifications.
For the manufacturer this fills capacity and spreads fixed costs, though it also builds a competitor to its own brand and gives the retailer detailed knowledge of production economics.
Specifications are typically written by the retailer, which means quality is a deliberate choice at a chosen price point rather than an inevitable consequence of being cheaper.
Retailers control the comparison
Placement, facings and price positioning are all decided by the party that owns one of the two products. Own-brand items are commonly placed directly beside the brand they reference.
Packaging similarity reinforces the comparison, and the boundary between legitimate reference and infringement is contested regularly, with the standards applied varying by jurisdiction.
The branded supplier therefore negotiates with an organisation that is simultaneously its largest customer and a direct competitor, which limits how hard it can push on any single issue.
Where brands retain the advantage
Categories with genuine technical differentiation, strong habitual preference, or a high perceived risk in switching remain difficult for own-brand products to take share in.
Categories where the product is largely undifferentiated and the specification is easy to replicate have seen own-brand share rise steadily over the long term.
Which category a product falls into is not fixed. It moves as manufacturing capability spreads and as retailers invest more heavily in their own product development functions.
