About: Marginal profit

In microeconomics, marginal profit is the increment to profit resulting from a unit or infinitesimal increment to the quantity of a product produced. Under the marginal approach to profit maximization, to maximize profits, a firm should continue to produce a good or service up to the point where marginal profit is zero. At any lesser quantity of output, marginal profit is positive and so profit can be increased by producing a greater amount; likewise, at any quantity of output greater than the one at which marginal profit equals zero, marginal profit is negative and so profit could be made higher by producing less.
