In the article possibilities of calculation of propensity by means of properly specified econometric models were presented. Propensities to consumption of chosen types of households in Poland were estimated (for the years 1993-2004) with application of Bayesian approach. Propensities for consumption were obtained for informative (Normal - Gamma distribution) and non-informative 'a priori' distribution. 'Highest Posterior Density Intervals' and parameters of precision for calculated estimators were also computed. Finally, distribution of propensities to consumption of analyzed types of households were presented
