Enter the consumer surplus and producer surplus into the calculator to determine the economic surplus. Economic surplus is the sum of consumer surplus and producer surplus, representing the total benefit to society from the production and consumption of goods and services.

Economic Surplus Formula

The following formula is used to calculate the economic surplus:

ES = CS + PS

Variables:

  • ES is the economic surplus ($)
  • CS is the consumer surplus ($)
  • PS is the producer surplus ($)

To calculate the economic surplus, add the consumer surplus to the producer surplus.

What is Economic Surplus?

Economic surplus, also known as total welfare or Marshallian surplus, is a measure of the economic benefit that is derived by consumers and producers as a result of participating in the market. Consumer surplus is the difference between what consumers are willing to pay for a good or service and what they actually pay, while producer surplus is the difference between what producers are willing to accept for a good or service and the actual price they receive. The sum of these two surpluses reflects the total gains from trade in the market.

How to Calculate Economic Surplus?

The following steps outline how to calculate the Economic Surplus:


  1. First, determine the consumer surplus (CS) in dollars.
  2. Next, determine the producer surplus (PS) in dollars.
  3. Use the formula from above = ES = CS + PS.
  4. Finally, calculate the Economic Surplus (ES) in dollars.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Consumer Surplus (CS) = $150

Producer Surplus (PS) = $200
