The work presents a level and a structure of stocks costs in relation to distance to supply markets. The research was carried out in 30 randomly selected farms in the south region of Poland. It was stated among others that an average index of stocks costs amounted to 87.2 PLN·t-1 of the stored goods and it decreased along with the increase of the distance from farms to supply markets from 101.0 PLN to 49.1 PLN. The costs of storing constituted 5.4-26.3% and the costs of maintenance were within the range of 74.7-94.6%. Limitation of stock depletion risk (40-69.2%) as well as protection against natural disaster were the main reasons of keeping stocks (42,9-70).
