PROBLEM TO BE SOLVED: To provide an information processor with shopping calculation function, a shopping calculation program, and a recording medium having the function of making a required calculation at shopping time, and capable of easily confirming a calculation history. SOLUTION: A store number is set by inputting a 'store' key 45, a numeric key, and a '=' key. After setting the store number, a shopping amount is inputted by a four-rule calculation key 40, and when inputting a 'capital' key 41, a shopping count increases by 1, and when inputting a 'change' key 42 by inputting the capital, a change amount is calculated by subtracting a payment amount from the capital. When finishing shopping at one store, a new store number is set, and the above shopping calculation is made. Since a shopping history is collected for every store number, the history can be confirmed in more detail.
