The objective of this article was to evaluate the yield and risk in the production and storage of the Arabian coffee. Cash flows are elaborated for coffee production in two productive systems, one with low productivity and other with high productivity. Twelve different scenarios are simulated, each one representing the returns and risks in the production and storage for every month of the year. The financial indicators Payback Period (PP), Net Present Value (VPL) and Internal Rate of Return (TIR) and the indicator Average Cost (CMe), suggest that high productivity is important to increase profitability and to decrease the activity risk, being the best periods to sale coffee, on the part of the producers, the months that precede the harvest, January, February and March.
