Market Equilibrium
Market equilibrium is a state in which the supply and demand for a product or service are in balance, resulting in a stable price for that product or service. In other words, the quantity of a product or service that buyers are willing and able to purchase is equal to the quantity that sellers are willing and able to sell.

When the market is in equilibrium, there is no excess supply or excess demand. Excess supply occurs when there are more sellers than buyers, and results in lower prices. Excess demand occurs when there are more buyers than sellers, and results in higher prices.
To understand market equilibrium, it is helpful to look at the relationship between supply and demand. The law of supply states that as the price of a product or service increases, the quantity of that product or service supplied will also increase. The law of demand states that as the price of a product or service decreases, the quantity of that product or service demanded will increase.
At a certain price, the quantity of a product or service supplied will be equal to the quantity demanded, resulting in market equilibrium. At this point, buyers and sellers are both satisfied with the price, and there is no incentive for them to change their behavior. If the price were to increase, sellers would supply more than buyers want to purchase, resulting in excess supply and lower prices. If the price were to decrease, buyers would demand more than sellers are willing to supply, resulting in excess demand and higher prices.
