Example of change Costing

IFC is a manufacturer of call cases. Below are excerpts from the company’s income statement for its recent year-end (2018):


IFC does no report an opened inventory. Throughout 2018, the agency manufactured 1,000,000 call cases and reported full manufacturing expenses of $598,000 (around $0.60 every phone case).

The manufacturer freshly received a unique order because that 1,000,000 phone cases at a total price the $400,000. Regardless of having ample capacity, the manager is wake up to expropriate this one-of-a-kind order because it is listed below the price of $598,000 come manufacture the early stage 1,000,000 phone instances as outlined in the company’s revenue statement. Being the company’s price accountant, the manager wants you to determine whether the company should expropriate this order.

Variable costing:

Direct material of $150,000Direct labor of $75,000Variable production overhead that $80,000

Total = $305,000 / 1,000,000 units created = $0.305 variable price per case

Cost to develop special order of 1,000,000 phone instances = $0.305 x 1,000,000 = $305,000. Therefore, there is a donation margin the $400,000 – $305,000 = $95,000.

Based on our variable costing method, the special order have to be accepted. The distinct order will add $95,000 of revenues to the company.

It is crucial to recognize why the manager was reluctant to expropriate the order. The manager had fixed expenses in the cost calculation, i m sorry is untrue in decision-making. Provided ample capacity, the company will no incur additional fixed costs to produce the distinct order that 1,000,000. Together you can see, variable costing plays an important role in decision-making!
