The computation algorithm for determination of the socio-economic development integral indicator based on the methods of factor analysis and expert evaluations has been described in the paper. By taking into account the knowledge and experience of experts, the factor model for evaluation of the level of socio-economic development has been improved. Based on the joint use of the methods of factor analysis and expert evaluation, the algorithm of automated computation  for integral indicators has been developed. The approach has increased the reliability of the results of calculations and made it possible to analyze the correlations between indicators in terms of their influence on the overall socio-economic situation. The developed computation algorithm is used in the educational process within the framework of teaching the discipline "Prognostics of socio-economic processes".
