DEVICE AND METHOD FOR ESTIMATING COST

PROBLEM TO BE SOLVED: To quickly and simply obtain the production cost of a molding on a design stage by providing a cost estimating device with an estimate reference data base part and a cost element calculating part for calculating each cost element based upon estimate reference data. SOLUTION: A CAD data storing part previously stores two-dimensional CAD shape data or the like of each molding to be calculated at its estimate. An information extracting processing part 10 extracts information necessary for estimate calculation from the CAD shape data, drawing information and so on. An input information processing part 3 receives information or the like which can not be extracted by the processing part 10 from an input processor 1 and processes the information or the like. The estimate reference data base part 11 stores cost factor information by functions of a component. The cost element calculating part 12 calculates each cost element by the use of the data base part 11 based upon the extracted information, input information and so on. A cost calculating processing part 7 mutually adds respective cost elements calculated by the calculating part 12 to calculate the production cost.
