The current state of most of Russia's territories is such that the development rates of specific regions remain low. This phenomenon does not allow for sustainable long-term economic security. Therefore, it is necessary to develop measures to determine the financial stability of the individual regions and territories of the country for the purposes of their development under current conditions. In this sense, the real problem is to determine the financial indicators to assess the economic security of rural areas. This can be achieved through the formation of a scientifically based action algorithm aimed at improving the situation in rural areas. The research topic is the formation of a system to identify financial indicators in the evaluation of the economic security of rural areas. The theoretical and practical significance of solving problems related to the achievement of sustainable development in rural areas determined the choice of goals, objectives, object and theme of this study. Based on the above, the object of the study is the municipal budget and agricultural enterprises as the basis for the development of rural areas. The purpose of the study is to establish the methodology for evaluating financial security in rural areas as a financial management instrument at the municipal level. The following tasks were implemented in the course of the study: selection of financial indicators based on official and expert sources; Foundation of the mathematical apparatus to calculate the comprehensive and private indicators of the financial security of the territory using the principles of qualimetry (the science of measuring quality). The proposed methodology allows to systematize the financial and economic indicators, it serves as the main calculation of the financial and economic security of the Udmurt Republic; the methodology can also be applied to other rural areas of the country.
