The objective of this study was to assess the economic viability of a Tectona grandis plantation subjected to thinning in the State of Mato Grosso and to compare the results with others Tectona grandis plantations in the state. There were simulated 4 forestry management alternatives with variations in the intensity of thinning , at 5, 10 and 15 years of age. It was considered a planning horizon of 20 years. Independent of the management alternative adopted, all were economically unviable, according to the Net Present Value (NPV) and Internal Rate of Return (IRR) methods. This behavior can be explained by the rate growth of the forest, which in this study was very low. It was designed a new stage of growth and carried out new economic analysis. From this new scenario, all forestry alternatives management were considered viable for the production of round wood. The alternative of 35, 35 and 25% reduction in basal area, for ages 5, 10 and 15 years respectively, was the most economically viable. The IRR for these management alternatives was higher than others, reaching 12%.
