Summary. Market equilibrium occurs when market supply equals market demand. The equilibrium price of a good or service, therefore, is its price when the supply of it equals the demand for it. If the market reaches equilibrium, the supply, demand, and price will generally be stable unless an external factor applies downward or upward pressure on demand or supply.
