The aim of the article is the development of a toolkit of models and methods for choosing a compromise rate for the management company and structural bu­siness unit within an integrated group of enterprises, making it possible to increase the efficiency of basic production activities of the holding company units and thus maintaining the stability of the financial sector and the profitability of corporate capital. The subject of the study is to investigate the influence of external factors of the market environment and controllable production factors of holding enter­prises on the effective rate for intercompany loans. The model calculations were carried out by the example of a virtual enterprise with a hierarchical organizational structure, for which the neoclassical dependence "labor-capital expenditures – out­put of commodity products" is valid for the divisions (technological divisions). As methods the article provides relevant economic and mathematical models for de­termining the effective rate of intra-company credit and a description of the origi­nal analytical method of selecting the compromise rate proposed by the aut hors. This rate was calculated by the example of test data, and the influence of each of the external factors on its value was studied. Interpretation of the results and specific steps for the holding enterprises to maximize the return on credit in the production sector and efficient corporate resource allocation is proposed.
