Perfect, or personalized, pricing involves charging each customer the maximum price they are willing to pay for a good or service. In theory, this practice extracts all consumer surplus, converting it into producer surplus. To determine the revenue and profit under this strategy, one must first identify each individual customer’s demand curve, and specifically, their reservation price. The firm then sells each unit at the highest price the customer is prepared to accept, accumulating revenue equal to the area under the aggregate demand curve up to the quantity sold. This area represents the total revenue collected, and subtracting the total cost of production from this revenue yields the total profit realized. An example is a consultant who negotiates a fee based on the perceived value they bring to each client individually.

This pricing approach, while often considered optimal for the seller, drastically alters the distribution of welfare within the market. Consumer surplus vanishes, as consumers pay their absolute maximum. The firm’s profit expands substantially compared to a single-price scenario or other forms of differentiated pricing. Historically, such pricing was more common in scenarios involving direct negotiation, such as bespoke goods or professional services. However, technological advancements, especially in data analytics and online platforms, have enabled more refined price targeting strategies that approximate personalized pricing in various sectors. The ability to gather detailed consumer data enables a closer estimation of individual willingness to pay.
