Differential Cost

Differential Cost Definition

Differential Cost is a technique of decision making in which the cost between various alternatives is compared and contrasted for the purpose of choosing between the most competing alternative.  It is useful when you want to understand a) Whether to process the product further or not b) Whether to accept an additional order at a lower existing price or not

It differs from the marginal cost in the sense that marginal costMarginal CostMarginal cost formula helps in calculating the value of increase or decrease of the total production cost of the company during the period under consideration if there is a change in output by one extra unit. It is calculated by dividing the change in the costs by the change in quantity.read more includes labor, direct expenses, and variable overheads, whereas differential cost includes both fixed and variable costs.

Examples of Differential Cost

The following are examples to understand this concept in a better manner.

Example #1

ABC Ltd is a company that produces card boxes. ABC Limited’s monthly cost statistics are as follows:

  • Units made and sold: 800 units per month
  • Maximum production and sales capacity: 1200 units per month
  • Selling price: $ 30

The bifurcation of cost is as given below:

ActivityVariable Cost per UnitFixed Cost per Unit
Manufacturing173060
Marketing & Administrative51740
Total224800

They are having an alternative to increasing the production of up to 900 by reducing the selling price at 28.

Please evaluate the feasibility of the option.

Solution 

Option 1: Present situation: selling price 30       

Example 1.1

 Hence, presently entity is earning a profit of $ 5600 per month.

Option 2: Alternative to increase the production

Differential Cost Example 1.2

Based on the two options, the cost of both the options can be evaluated as given below:

Example 1.3

From the above analysis, we can observe that with the change in the alternative, an entity will have to incur an additional cost of $ 1000. Hence an increase in production is not advisable. 

Example #2

Continuing the above example, ABC Ltd has an opportunity for a one-time-only special order to sell 100 units at $25 each. Should they accept the special order?

Solution 

Option 1: Present Situation

Example 2

Option 2: Accepting one-time order

Differential Cost Example 2.1

The differential analysis of both the options are as given below:

Differential Cost Example 2.2

Thus, we can observe that there is an increase in profit after accepting the order. Hence, ABC ltd should accept the order and should enhance their profit.

Usage of Differential Cost Analysis

  • Getting Prices of Products: What can be the optimum price quoted through which tended can be won.
  • Accepting or Rejecting Special Orders: Whether to work out in any additional specific order that comes in business or not.
  • Adding or Eliminating Products, Segments, or Customers: Whether to continue or to diversify from any specific business segment or not.
  • Processing or Selling Joint Products: Whether to co-produce or co-sell the products or to jointly market the products;
  • Deciding whether to Make Products or Buy them: Whether to manufacture the product or to leverage the production facility of others.
