The price point on the original demand curve is I and the new demand curve is G, while the prices are OE and OC respectively. Step 4: Next, compute the difference between the original and new equilibrium quantity. Step 5: Next, compute the difference between the prices paid for the original and new demand curve at the new equilibrium quantity. Step 6: Finally, the formula for deadweight loss is expressed as the area of the triangle with base equivalent to price difference step 5 and height equivalent to quantity difference step 4 as shown below.
The concept of deadweight loss is important from an economic point of view as it helps is the assessment of the welfare of society. Basically, it is a measure of the inefficiency of a market, such that a higher value of deadweight loss indicates a greater degree of inefficiency prevalent in the market.

In the deadweight loss graph below, the deadweight loss is represented by the area of the blue triangle , which is equal to the price difference base of the triangle multiplied by the quantity difference height of the triangle , divided by 2. Now that we learned how to calculate deadweight loss, we can see from this deadweight loss formula that the more the new price deviates from the original one, the greater the deadweight loss.
Furthermore and this usually goes hand in hand with the price difference , the more the new quantity differs from the original one, the higher the deadweight loss. Our deadweight loss calculator allows you to estimate the deadweight loss of a market in four simple steps:.
Under the new market conditions, the consumers and the producers both profited from the new measure, but the government incurred the cost - a cost greater than the consumer and producer surpluses combined.
The overall economic welfare of the country decreased by an amount equal to the deadweight loss. To calculate this loss, we type 1 in the field "Original price" , 0. Embed Share via. Table of contents: What is deadweight loss? How to calculate deadweight loss?
Using the deadweight loss calculator. Read on if you want to know what is deadweight loss and how to calculate it. What is deadweight loss? To understand the deadweight loss definition, let's first observe some general economic concepts: In an unregulated and monopoly-free market, where prices are naturally set by supply and demand, the total economic welfare generated by that market is equal to the sum of what we call the consumer surplus and the producer surplus.
Using the deadweight loss calculator Our deadweight loss calculator allows you to estimate the deadweight loss of a market in four simple steps: Enter the original free-market price of the product in the field "Original price". Fill in the new price of the product in the field "New price".

Deadweight losses primarily arise from an inefficient allocation of resources, created by various interventions, such as price ceilings, price floors, monopolies, and taxes.
These factors lead to the price of a product not being accurately reflected, meaning goods are either overvalued or undervalued. If the price of a product is not reflected accurately, this leads to changes in consumer and producer behavior, which usually has a negative impact on the economy.
