Graphically Representing Deadweight Loss Consider the graph below: At equilibrium, the price would be $5 with a quantity demand of 500. Now, the cost exceeds the benefit; you are paying $40 for a bus ticket, from which you only derive $35 of value. The profit is calculated by subtracting total cost from total revenue ($1200 - $400 = $800).

With this new tax price, there would be a deadweight loss: As illustrated in the graph, deadweight loss is the value of the trades that are not made due to the tax.

In a perfectly competitive market, firms are both allocatively and productively efficient. Instead, demand and supply are moved artificiallyby factors like taxation, subsidies, product surplus, consumer surplus, monopoly, oligopoly, price ceiling, and price floor. That's because producers are compelled to want to create less supply as a result of a tax. Solution:Dead weight = 0.5 * (P2-P1) * (Q1-Q2).

Alternatively, you can find total revenue and total cost's rectangles and then find that difference. Finding this rectangle is pretty much the same as in perfect competition: find our price point, go up or down to the ATC, and then go over to finish off the rectangle.
