A method for cost estimation in the period of conceptual design was presented in this paper. First a model based on weight similarity was proposed for measuring the similarity between the features of a sample and the product whose cost needed to be estimated. Then by analyzing the similarity and fitting the data, a result of cost estimation with good precision was obtained.
