Key Takeaways A consumer surplus happens when the price consumers pay for a product or service is less than the price they're willing to pay. Consumer surplus is based on the economic theory of marginal utility, which is the additional satisfaction a consumer gains from one more unit of a good or service.

Many producers are influenced by consumer surplus when they set their prices. Compare Accounts.

Related Terms Understanding the Law of Supply and Demand The law of supply and demand explains the interaction between the supply of and demand for a resource, and the effect on its price.

Producer Surplus Definition A producer surplus is the difference between the amount of a good the producer is willing to accept for a product versus how much he actually receives in the transaction. 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.

So any increase in consumer surplus due to the decrease in price may be offset by the fact that consumers that want the good cannot purchase it. When a price floor is set above the equilibrium price, consumers will have to purchase the product at a higher price. Therefore, fewer consumers will purchase the product because some will decide that the utility they get from the good is not worth the price.

Necessarily, this reflects a drop in consumer surplus. Privacy Policy. Skip to main content. Economic Surplus. Search for:. Consumer Surplus. Willingness to Pay and the Demand Curve In general as the price of a good increases, the quantity demanded of that good decreases. Learning Objectives Explain the relationship between price and quantity demanded. Key Takeaways Key Points Demand is the willingness and ability of a consumer to purchase a good under certain circumstances.

Key Terms demand curve : The graph depicting the relationship between the price of a certain commodity and the amount of it that consumers are willing and able to purchase at that given price. The Demand Curve and Consumer Surplus Consumer surplus is the difference between the maximum price a consumer is willing to pay and the actual price they do pay.

Learning Objectives Illustrate consumer surplus with the demand schedule and demand curve. Key Takeaways Key Points On a supply and demand chart, consumer surplus is bound by the y-axis on the left, the demand curve on the right, and a horizontal line where y equals the current market price.

Key Terms consumer surplus : The difference between the maximum price a consumer is willing to pay and the actual price they do pay. That for any given the quantity of the good you're selling, that that point on the curve is actually showing the marginal benefit for that incremental unit. So this is a marginal benefit for that first unit. This is the marginal benefit for that second unit.

And there's multiple ways that you could view this, assuming that we're talking about this new car here. Now, let's say if you want to sell two units, that second unit might be bought by that same person. And they might say, well, I already have one car. That's the point at which I am neutral. That's the point at which I'm right on the fence of willing to buy that car. But when you think about that reality, what's actually happening is that this fourth person is right on the fence.

So it's kind of like, hey, will you be willing to trade this dollar for a dollar? Well, you probably would be kind of on the fence about that. You're very close to going either way. You feel like it's a good deal if you could get it for maybe a penny less. It's a bad deal if you're getting it for a penny more. So right on the fence, but you're going to just barely get this fourth person to transact at this price.
