Features of calculating the initial (maximum) prices of contracts in the implementation of public procurement

Justification of the initial (maximum) contract price is one of the main tools used at the stage of supplier selection. Establishing the marginal price of the contract has a significant impact on the quality of work performance, qualification of the supplier and, as a consequence, on the efficiency of budget financing utilization as a whole. The aim of the study is to analyze the correctness of the methods used in practice to calculate the initial (maximum) prices of contracts enshrined in the regulatory legal acts of the Russian Federation. Thus, the methods of analysis, synthesis, abduction and comparison of the obtained mathematical calculations were used in the work. The documentation attached to the notices published in the Unified Information System justifying the calculation of the marginal price of various contracts has been analyzed. In the course of the analysis, the author calculated the coefficients necessary to decide on the acceptability of the values applied by customers at the stage of supplier selection, in particular, the coefficients of variation and mean square deviation used in the method of comparable market prices. The study identified cases of incorrect application of mathematical justification models in determining the amount of funding aimed at realizing the objectives of budgetary institutions. Such incorrect application of models can lead to an increase in the cost of work and, as a result, the risks of unfair behavior of participants in the contract model.
