PROBLEM TO BE SOLVED: To provide a program execution time analytical method and a device for analyzing a program statically and predicting an execution time (performance value) without actual operation by a computer. SOLUTION: This device is constituted by a processing structure analytical means 101 for inputting a source program 111, analyzing the processing structure of the source program, and extracting variables exerting an influence on the execution time, a data structure analytical means 102 for analyzing the data structure of the source program relative to the variables extracted by the processing structure analytical means, and extracting a variable requiring input of a value, an estimation data input means 103 for inputting the value into the variable extracted by the data structure analytical means, and an execution time evaluation means 104 for estimating the execution time corresponding to the value inputted by the estimation data input means. The device can analyze the program, calculate an index for comparing and evaluating the length of the execution time, and estimate the execution time.
