This work evaluated the economic viability of a teak plantation (Tectona grandis L.f. ) submitted to thinning. The following economic criteria of project analysis were applied: Net Present Value, Equivalent Annual Benefit (Cost), Internal Return Rate and Land Expected Value. The discount rate applied was 10% a year. The indicators showed the economic viability of the teak plantation, under the conditions established in the analysis. The plantation will not be viable by reducing 25% of the revenues or increasing 35% of the costs, being more sensitive to the variations in income decrease than to variations in cost increase.
