The vacancy rate calculation apparatus receives table identification information of a table at which a customer or customers is/are seated and the number of the customer or customers and determines whether or not the number of the customers exceeds the number that can be seated at the table. When it is determined that the number of the customers exceeds, the vacancy rate calculation apparatus determines whether or not another table is vacant which can be combined with the table indicated by the received table identification information. When it is determined that said another table is vacant, the vacancy rate calculation apparatus stores the table identification information of said another table at which a customer is assumed to be seated, along with the received table identification information.
