The aim of the paper is to identify and evaluate the development opportunities for farms in Poland in terms of area groups. The analysis covered the 2015-2019 period and was based on the results of individual farms keeping agricultural accounts under the Polish FADN. The paper determined the level and rate of accumulation, as well as the level of depreciation, taxes and fees, operating subsidies, and the ratio of operating subsidies to public accumulation and support that the farms receive under the Common Agricultural Policy (CAP). The results indicate the financial and organizational diversity of the group of farms. Very small, medium-large, large, and very large farms had a positive accumulation rate. In this group of farms, the accumulation in terms of value covered the depreciation, and even in the case of large and very large farms it exceeded the depreciation. By contrast, small and medium-small farms were characterized by negative accumulation rates, which was associated with the lack of reproduction of fixed assets. These farms have no development opportunities. In conclusion, the ratio of subsidies to public accumulation is the most beneficial in the case of medium-large farms, where the ratio of subsidies to fiscal burden was over 20:1. Very small farms receive the least benefits under the CAP in terms of public accumulation. In this case, the ratio of subsidies to public accumulation is approximately 2:1 throughout the entire research period.
