We evaluated the viability of the strawberry small farm in Paraná, in two areas, 0.3 ha (average area cultivated by family farms) and 1 ha, during a year. A spreadsheed cash flow was prepared in which it was calculated: Payback Period of Capital (PPC), Return on Investment (ROI), Net Present Value (NPV) and Internal Rate of Return (IRR). All for Operational Cost Effective (OCE), Total Operating Cost (TOC) and Total Cost of Production (TCP). In a situation considered normal, profitability indicators calculated were (Cost Type: NPV standard area (IRR standard area) / NPV effective area (effective area IRR)) OCE: US$ 17.856,55 (42%) / US$ 4.795,85 (39%); TOC: US$ 5.182,40 (11%) / - US$ 1.691,97 (-13%), TCP: US$ 4.846,26 (10%) /- US$ 1.792,80 (- 14%). A scenario analysis was made for the factors productivity, sales price and manpower, analyzing the NPV and IRR. The size of the area influenced the economic viability, showing the importance of determining annually the minimum viable area for family farms. The results indicated that culture is viable in the short term, when considered as a parameter of the OCE analysis, but can not be sustained in longer when considering the TOC, TCP and variation of some factors of production. By analysis of scenarios defined by production factors, NPV and IRR change to risky levels exploitation.
