Abstract Provided is a computation apparatus that is able to adequately obtain a relative value of an incentive point issued by each shop, by computing an exchange rate used in exchanging shop points of the shop into common points. The computation apparatus stores a function for defining the exchange rate, and internally maintains, for rate computation, the used house point (UHP) that represents a portion of shop points that has been spent (redeemed) in a shop that has issued the shop points), and the active general point (AGP) that represents a portion of common points that is obtained by exchanging shop points and is not spent yet. A rate function is defined so as to yield a higher exchange rate in exchanging shop points of the shop into common points when the used house point (UHP) of the shop is larger, and to yield a lower exchange rate when the active general point (AGP) of the shop is larger.
