Consumer surpluses are affected by price elasticity of demand (which refers to the relationship between the price of and demand for a product). In a graph like the one shown above, the formula for calculating consumer surplus is 1/2 the length of the base multiplied by the overall height. Where, Qe = Quantity demanded at equilibrium, where Supply = Demand. This column argues this observation has powerful implications for understanding rent seeking and price controls. Consider the market price (equilibrium price) and the maximum price at which the purchased product falls to zero. Consumer surplus refers to the amount of product's price which the consumer pays reduced from the total product's price consumer willing to pay. Consumer surplus will only increase as long as the benefit from the lower price exceeds the costs from the resulting shortage. The formula used for calculating it is: 1/2 base x height. To find the maximum price that the consumer is willing to pay. Consumer surplus: Consumer surplus is quite easy to understand, since it’s the difference between how much someone is willing to pay for a given quantity of goods, an how much they actually pay. We base the formula on an economic theory of marginal utility. To get the height, find the difference between the maximum willingness to pay (where demand intercepts the price axis) and market price. Difference between (1) and (2). Consumer Surplus is defined as the difference between the amount of money consumers are willing and able to pay for a good or service (i.e. Consumer Surplus = ½ * Demand Quantity at Equilibrium * (Maximum Price Willing to pay – Market Price) This is also known as the extended consumer surplus formula.

The above formula is a simple representation of how consumer surplus can be obtained. In more complicated problems, however, you need to gather the value from the demand curve. Consumer Surplus. Consumer surplus = maximum price (consumers are willing to pay) – actual price. Extended Formula to calculate Consumer Surplus : Consumer Surplus = Qe x ΔP. To get the base, find equilibrium quantity (Q*). From the definition, consumer surplus is actually the difference between the highest amount consumers are willing to pay and the actual price they pay for the goods and services. If you think back to geometry class, you will recall that the formula for area of a triangle is ½ x base x height. Calculate how much consumers actually pay for a good.

Another way to calculate consumer surplus is through demand and supply graph. So essentially, you could view this as the area of this little thing right over here. In simple terms, you can just subtract the amount paid from the expected amount value.

On a graph, consumer surplus equals the area above the market price and below the demand curve. If we can remember the formula for area of a triangle, that is fine. Producer surplus and consumer surplus both amount to the total benefit to society – otherwise known as the economic surplus. The total economic surplus equals the sum of the consumer and producer surpluses. Consumer surplus generally declines with consumption. Declining consumer surplus. If you're using the formula to find what you need to deposit today to have a certain value \(P\) sometime in the future, \(t \lt 0\) and \(A(t)\) is called the present value.
