The purpose of bagging table guava fruits is to protect them against attack of insects and to reduce application and residue levels of agrochemicals. The aim of this study was to evaluate the economic sustainability of guava production through the comparison between the production costs of bagging and non-bagging systems. This study was carried out using data from a commercial table guava orchard sited in Valinhos - SP. In this case, the production cost was represented by Total Cost (TC), which is composed by the Operational Cost (OC) and the Annual Costs of Asset Renewal method (ACARM). In this case, the TC of the guava bagging production system was R$ 72,208.39 ha-1 against R$ 66,467.30 ha-1 for the non-bagging system. To maintain producer's net revenue, the average price must raise from the current R$ 1.85 kg-1 to at least R$ 1.96 kg-1 when the fruits are capped by bags. Both production systems have shown to be sustainable once the gross revenue is superior to the Total Cost.
