The article lists the main sources (objects and processes) that generate costs - a total of 19 possible sources, grouped into four groups. To monitor and take measures to reduce costs, it is advisable to build a formalized model and on its basis a software system that would allow to estimate all costs. This article is devoted to the construction of this model. An article on the estimation of total costs for all possible factors leading to losses and costs in warehouse freight turnover is not available in the literature.
