An information processing method includes: deciding a timing when transfer to a memory is completed in a total time that is a sum of a calculation time at one or plurality of second layers at which calculation is carried out earlier than a first layer regarding a timing when data relating to calculation of the first layer is stored in the memory based on a calculation time estimated in advance regarding each of one layer or a given number of layers in a plurality of layers included in a neural network and a time of transfer of data relating to calculation of each of the one layer or the given number of layers to the memory; and storing the data relating to calculation of the first layer in the memory based on the decided timing in sequentially carrying out calculation of each layer of the neural network.
