User pays, or beneficiary pays, is a pricing approach based on the idea that the most efficient allocation of resources occurs when consumers pay the full cost of the goods that they consume. In public finance it stands with another principle of "ability to pay," which states that those who have the means should share more of the burden of public services. The ability to pay principle is one the reasons for the general acceptance of the progressive income tax system.
