The company has excess capacity and should only consider the relevant costs. Therefore, the cost to produce the special order is $200 per item ($125 + $50 + $25). If a client wants a price quote for a special order, management only considers the variable costs to produce the goods, specifically material and labor costs. Fixed costs, such as a factory lease or manager salaries are irrelevant, because the firm has already paid for those costs with prior sales.

  • For this reason, non-cash items such as depreciation would not be classed as a relevant cost.
  • For the cost to be considered ‘relevant’, it needs to satisfy all three criteria.
  • In that case, the cost of the warehouse which stores the production unit is avoidable because you can sell the warehouse.
  • It considers the total dollars of the mixed costs at the highest volume of activity and the total dollars of the mixed costs at the lowest volume of activity.
  • Avoidable CostsOnly those costs are relevant to a decision that can be avoided if the decision is not implemented.

These differences—not the similarities—form the basis of the analysis comparison. Electricity charges are incremental to this order and therefore relevant. Lease rentals are a committed cost which cannot be avoided by withdrawing from this order which is why they should be ignored for the purpose of this analysis. This represents the apportionment of general and administrative overheads based on the number of machine hours that will be required on the order. This represents the manufacturing equipment’s depreciation for the number of days in which production for the order will take place.

Example of Incremental Analysis

In many situations, this increased allocation to other product lines may cause other product lines to appear unprofitable. The message here is to be careful when analyzing segmented information containing cost allocations. Allocated costs are typically not differential costs, and therefore are typically not relevant to the decision.

As you can see, even though the total fixed costs remain unchanged at $150,000, the fixed cost per unit will change depending on how many bicycles are produced. In May, the fixed costs per bicycle were $300, while in June, that number was $200. Contribution margin means a measurement of the profitability of a product. Allocated fixed costs (also called common fixed costs) are fixed costs that cannot be traced directly to a product line, and therefore are assigned to product lines using an allocation process. For example, rent paid for Barbeque Company’s retail store is allocated to all three product lines because it is not easily traced to each product line. However, the retail store rent likely will not decrease if the charcoal barbecues product line is eliminated (unless the company chooses to move to a smaller, less costly store).

What’s a Limitation of Incremental Analysis?

An opportunity cost For example, assume you have the choice between going to school and working. The opportunity cost of attending school is the lost wages from working. Notice tax dates and deadlines in 2021 that in Figure 4.1 “Differential Analysis for Phillips Accountancy” the columns labeled Alternative 1 and Alternative 2 show revenues, costs, and profit for each alternative.

Special order

However, even long term financial decisions such as investment appraisal may use the underlying principles of relevant costing to facilitate an objective evaluation. Note that additional fixed costs caused by a decision are relevant. So, if you were evaluating the viability of a new production facility, then the rent of a building specially leased for the new facility is relevant. The book value of fixed assets like machinery, equipment, and inventory is another example of irrelevant sunk costs. The book value of a machine is a sunk cost that does not affect a decision involving its replacement.

Opportunity

The closure of Production Line A would also result in the revenue lost being greater than the value of the costs saved, so this isn’t a good idea either.

For example, a furniture manufacturer is considering an outside vendor to assemble and stain wood cabinets, which would then be finished in-house by adding handles and other details. The relevant costs in this decision are the variable costs incurred by the manufacturer to make the wood cabinets and the price paid to the outside vendor. If the vendor can provide the component part at a lower cost, the furniture manufacturer outsources the work.

Relevant costing attempts to determine the objective cost of a business decision. An objective measure of the cost of a business decision is the extent of cash outflows that shall result from its implementation. Relevant costing focuses on just that and ignores other costs which do not affect the future cash flows. A relevant cost is any cost that will be different among various alternatives. There is seldom a “one-size fits all” situation for relevant or irrelevant costs. CM can be calculated for a product line using total revenues and total variable costs.
