Because of the law of diminishing marginal utility, the demand curve is downward sloping. Consumer surplus is measured as the area below the downward-sloping demand curve, or the amount a consumer is willing to spend for given quantities of a good, and above the actual market price of the good, depicted with a horizontal line drawn between the y-axis and demand curve. Consumer surplus can be calculated on either an individual or aggregate basis, depending on if the demand curve is individual or aggregated.
Economic welfare is also called community surplus, or the total of consumer and producer surplus. Consumer surplus always increases as the price of a good falls and decreases as the price of a good rises.
Consumer surplus is zero when the demand for a good is perfectly elastic. But demand is perfectly inelastic when consumer surplus is infinite. Consumer surplus is the benefit or good feeling of getting a good deal.
However, businesses know how to turn consumer surplus into producer surplus or for their gain. The airline knows there will be a spike in demand for travel to Disney World during school vacation week and that consumers will be willing to pay higher prices. So by raising the ticket prices, the airlines are taking consumer surplus and turning it into producer surplus or additional profits.

This chart graphically illustrates consumer surplus in a market without any monopolies, binding price controls, or any other inefficiencies. The price in this chart is set at the pareto optimal.
This means that the price could not be increased or decreased without one of the parties being made worse off. The consumer surplus, as marked in red, is bound by the y-axis on the left, the demand curve on the right, and a horizontal line where y equals the equilibrium price.
This area represent the amount of goods consumers would have been willing to purchase at a price higher than the pareto optimal price. Generally, the lower the price, the greater the consumer surplus. Consumer Surplus : Consumer surplus, as shown highlighted in red, represents the benefit consumers get for purchasing goods at a price lower than the maximum they are willing to pay. Some goods, like water, are valuable to everyone because it is a necessity for survival.
Since the utility a person gets from a good defines her demand for it, utility also defines the consumer surplus an individual might get from purchasing that item. However, if a person finds a good incredibly useful, consumer surplus will be significant even if the price is high. Consumer surplus decreases when price is set above the equilibrium price, but increases to a certain point when price is below the equilibrium price.
Consumer surplus is defined, in part, by the price of the product. Recall that the consumer surplus is calculating the area between the demand curve and the price line for the quantity of goods sold. Assuming that there is no shift in demand, an increase in price will therefore lead to a reduction in consumer surplus, while a decrease in price will lead to an increase in consumer surplus.
Consumer Surplus : An increase in the price will reduce consumer surplus, while a decrease in the price will increase consumer surplus. The total economic surplus equals the sum of the consumer and producer surpluses. A binding price ceiling is one that is lower than the pareto efficient market price. This means that consumers will be able to purchase the product at a lower price than what would normally be available to them.
It might appear that this would increase consumer surplus, but that is not necessarily the case. For consumers to achieve a surplus they have to be able to purchase the product, which means that producers have to make enough to be purchased at a price. So while more consumers will want to purchase the product because of its low price, they will not be able to.
This means the market will have a shortage for that good. This shortage will create a deadweight loss, or a market wide loss of efficiency and value that neither producer nor consumers obtain.

Video transcript Let's say you run an orange stand. And this right here, you could view this as either the demand curve for your orange stand or your marginal benefit curve, or really you could call it the willingness to pay, the first pounds of oranges.
But then the st pound would be a little bit less than that. So that's the willingness to pay, or the marginal benefit of that incremental pound. What I want to think about is, what is the total consumer surplus that your consumers got? And the way to think about consumer surplus is, how much benefit did they get above and beyond what they paid?
So for example, the person who bought-- let's just think about the exact th pound. So if you wanted to figure out the entire consumer surplus, well, you just have to do it for all of the pounds. So that was th pound. So essentially, you could view this as the area of this little thing right over here.
