The calculation of efficiency indicators in the production of grain and leguminous crops is carried out on the example of the Irkutsk region. Given that the production of agricultural products occurs under conditions of uncertainty, the initial data for calculating these indicators are random variables, so the calculations are carried out using a probabilistic break-even analysis based on the Monte Carlo method. The break-even point, invested income, and operating profit are selected as performance indicators. Based on the given initial data of the Ministry of Agriculture of the Irkutsk Region and the Federal State Statistics Service for the Irkutsk Region, point and interval estimates were obtained during modeling. For the listed performance indicators, the models of their calculation, depending on the source data, are given. As initial data there are: the volume of production of grain and leguminous crops; expenses for a production unit; fixed costs; average price per unit of production; the size of the subsidies.
