Loss leader
A loss leader is a product sold at or below cost to attract customers who then buy more profitable items.
Sometimes a shop sells you something at a loss on purpose, because the real profit lies in what you buy alongside it. That deliberately cheap item is a loss leader.
A loss leader is a product sold at or below cost, deliberately and at a loss, to attract customers in the expectation that they will also buy other, more profitable items. It is a pricing tactic that sacrifices profit on one product to drive overall sales and profit, using the cheap item as bait to draw customers in.
Bait for the basket
The logic of the loss leader is that the loss on the bait item is more than recovered by the profit on what customers buy alongside it. A supermarket sells a staple at a loss to draw shoppers in, knowing they will fill their basket with profitable items while there. A retailer sells a console near cost to profit from the games. A cheap headline product attracts customers whose overall spending, on full-margin goods, makes the visit profitable. The loss leader is not a mistake but a calculated sacrifice, trading profit on one item for the larger profit on the whole transaction or relationship it brings.
Where it works
Loss leaders work where the cheap item genuinely draws customers who then buy other, profitable things. This requires that customers do not simply take the loss leader and leave, the cherry-pickers who buy only the bargain, but go on to spend on profitable items, and that the traffic the loss leader generates translates into overall profit. It is common in retail, where a tempting bargain draws footfall, and in products with profitable complements or follow-on sales, where cheap hardware leads to profitable consumables or services. The tactic depends on the link between the bait and the profitable purchases it is meant to trigger.
The risks
Loss leaders carry dangers. Customers may buy only the loss leader and nothing else, the cherry-pickers who take the bargain and leave, turning the tactic into pure loss. Selling below cost can attract resellers who buy in bulk to exploit the price. The tactic can trigger price wars if competitors match, and in some places selling below cost is restricted by law as unfair competition. And reliance on loss leaders can train customers to shop only the bargains, eroding the full-margin sales the tactic depends on. The loss leader works only when the loss is genuinely recovered through the profitable sales it brings.
The loss leader is the deliberate sale of a product at a loss to draw customers who will buy profitable items alongside it, a calculated sacrifice that trades margin on the bait for the larger profit of the whole basket or relationship. Effective where the cheap item genuinely drives profitable purchases, it is undone by cherry-pickers who take only the bargain, which is why the tactic rewards a clear understanding of whether the loss is truly recovered by what the bargain brings through the door.
