Lavender is a perennial shrub cultivated primarily for its inflorescence which produces high value essential oil. In Turkey, a great deal of studies has been done regarding the calculation of input, cost and profit of many agricultural products. However; there are not sufficient studies for medical and aromatic plants. In this study, it was aimed to determine the production inputs, costs and profitability of lavender farms. As research field, Isparta Province, which constitutes significant portion of Turkey's lavender production, was chosen. The material of this study consists of data obtained through face-to-face surveys with 38 farmers. The mean yield of farm was calculated as 1636.70 kg ha(-1) while 1 kg lavender production cost was calculated as $0.95. The average selling price of farm for 1 kg of lavender was $1.57. The GPV from lavender farming was calculated as 2573.31$ha(-1). Gross profit and the net profit were calculated as $1695.08 and 1018.37 $ha(-1) respectively. Relative profit was found to be 1.65. Lavender production was an alternative and important source of income for producers in region. Therefore, governmental support to lavender can lead to improvements in profitability indicators.
