Explanation:

Dead-weight loss is also known as excess burden. It is a situation where in there is a loss of economic sufficiency as a result of tax.

This economic sufficiency is when the supply of goods and services aren't met. That is, there is no market equilibrium between demand and supply. Taxes, subsidies, price rise or fall can be the reason for dead-weight loss as it causes the imbalance of demand and supply of goods or services to the consumers through price manipulations.

To calculate dead-weight loss, change in price as well as change in quantity demanded are important factors to consider.
