total surplus can be defined as the eagerness to pay price, less than the economic cost. Total surplus is increased in a free market competition when free market equilibrium has been attained.
Consumer surplus is the gain which is obtained by consumers when they are able to purchase a product for a price that is less than the highest amount that they would be willing to pay for that product. Producer surplus is the amount that is acquired by the producers by selling at a market price that is higher than the lowest amount that they would be willing to sell the product for.
