Normal profit is the minimum level of profit needed for a company to remain competitive in the market.
Also known as "economic profit".
Normal profit occurs at the point at which the resources available to the firm are being efficiently used and could not be put to better use elsewhere. It is important to note that zero economic profit does not mean that the company is not earning any money (accounting profit). It is simply a measure of how well resources are being used relative to all possible options.
