What is 'Demand'. Demand is an economic principle that describes a consumer's desire and willingness to pay a price for a specific good or service. Holding all other factors constant, an increase in the price of a good or service will decrease demand, and vice versa. Think of demand as your willingness to go out and buy a certain product. For example, market demand is the total of what everybody in the market wants.
