Switching Costs

also: switching cost engineering · lock-in

Definition

Switching costs are the total economic, procedural, and psychological burden a customer incurs when moving from one vendor to another. Klemperer's taxonomy decomposes them into transaction, learning, contractual, uncertainty, and psychological components, each with different decay rates and defensive strategies.

Switching costs act as a form of market power — a firm with locked-in customers can sustainably charge above the competitive price by an amount up to the switching cost. Klemperer's five categories (transaction, learning, contractual, uncertainty, psychological) differ in reversibility: contractual costs are easy to buy out, learning costs are hard to refund. The number of integrated touchpoints drives quadratic growth in total switching friction via the n(n-1)/2 interaction term.
