In economics, an isoquant (derived from quantity and the Greek word iso [meaning equal]) is a contour line drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs. Another way of defining the isoquant is a curve that shows all possible quantities of inputs that result in the same level of output with a given production function. While an indifference curve helps to answer the utility-maximizing problem of consumers, the isoquant deals with the cost-minimization problem of producers.
