Chapter 7 Variable Costing: A Tool for Management 3/17/04

2 Absorption Costing Treats all manufacturing costs as product costs, and non-manufacturing costs as period costs Unit costs consist of direct material and direct labor and both variable and fixed manufacturing overhead. Fixed manufacturing overhead is allocated to each unit of production GAAP

3 Variable Costing Only those costs of manufacturing that vary with output (variable costs) are treated as product costs This would include direct material, direct labor and variable manufacturing overhead Fixed manufacturing overhead is expensed during the current period Variable costing is used for internal planning and control only; it’s not GAAP!

4 Overview of Absorption and Variable(Marginal) Costing
The only cost of driving my car on a 200 mile trip today is $12 for gasoline. Variable Costing

5 Overview of Absorption and Variable Costing
No! You must consider these costs too! Absorption Costing

6 Overview of Absorption and Variable (Marginal) Costing
You are wrong. I have the car payment and the insurance payment even if I do not make the trip. Variable Costing

7 Overview of Absorption and Variable Costing
Who’s right? How should we treat the car payment and the insurance?

8 Marginal Costing Provides a useful tool for evaluating marginal business propositions Example, WTT exhibit Marginal costs versus fixed costs

13 Quick Check  Which method will produce the highest retained earnings? (Hint: Remember the balance sheet equation.) a. Absorption costing b. Variable costing c. There would be no difference in retained earnings under the two methods. d. It depends ...

Which method will produce the highest retained earnings? (Hint: Remember the balance sheet equation.) a. Absorption costing, because some fixed costs stay in inventory until the product is sold b. Variable costing c. There would be no difference in retained earnings under the two methods. d. It depends ... Assets = Liabilities + Owners’ Equity  

15 Overview of Absorption and Variable Costing
Let’s put some numbers to the issue and see if it will sharpen our understanding.

16 Unit Cost Computations
Harvey Co. produces a single product with the following information available:

17 Unit Cost Computations
Unit product cost is determined as follows: Selling and administrative expenses are always treated as period expenses and deducted from revenue.

18 Income Comparison of Absorption and Variable Costing
Harvey Co. had no beginning inventory, produced 25,000 units and sold 20,000 units this year.

19 Income Comparison of Absorption and Variable Costing
Harvey Co. had no beginning inventory, produced 25,000 units and sold 20,000 units this year.

20 Income Comparison of Absorption and Variable Costing
Now let’s look at variable costing by Harvey Co. Variable costs only. All fixed manufacturing overhead is expensed.

21 Quick Check  The net operating income under absorption costing was $120,000 and under variable costing it was $90,000 because of higher expenses. Where is the missing $30,000 under absorption costing? a. It has disappeared into an accounting black hole. b. It is in ending inventories. c. It represents taxes that have been saved. d. The $30,000 wasn’t a real cost, so nothing is really missing.

The $30,000 wasn’t a real cost, so nothing is really missing.

23 Income Comparison of Absorption and Variable Costing
Let’s compare the methods.

24 Reconciliation We can reconcile the difference between absorption and variable income as follows: Fixed mfg. overhead $150,000 Units produced ,000 units = = $6.00 per unit

25 Extending the Example Let’s look at the second year of operations
for Harvey Company.

26 Harvey Co. Year 2 In its second year of operations, Harvey Co. started with an inventory of 5,000 units, produced 25,000 units and sold 30,000 units.

27 Unit product cost is determined as follows:
Harvey Co. Year 2 Unit product cost is determined as follows: No change in Harvey’s cost structure.

28 produced in the current period.
Harvey Co. Year 2 These are the 25,000 units produced in the current period.

29 All fixed manufacturing overhead is expensed.
Harvey Co. Year 2 Variable costs only. All fixed manufacturing overhead is expensed.

30 Reconciliation We can reconcile the difference between absorption and variable income as follows: Fixed mfg. overhead $150,000 Units produced ,000 units = = $6.00 per unit

31 Summary

32 Comparative Income Effects Exhibit 7-4
Production = Sales No change in inventory; income the same for both absorption and variable costing Production > Sales Inventories increase; Absorption Income higher than Variable Cost income due to more fixed cost retained in inventory Production < Sales Inventories decrease; Absorption Income lower than Variable Cost income as more fixed costs are released from inventory

33 Advantages of the Variable Cost Approach
Consistent with CVP analysis. Management finds it easy to understand. Can be used for marginal Cost analysis. Advantages Easier to estimate profitability of products and segments. Profit is not affected by changes in inventories. Impact of fixed costs on profits emphasized.

34 Variable versus Absorption Costing
All manufacturing costs must be assigned to products to properly match revenues and costs. Fixed costs are not really the costs of any particular product. Variable Costing Absorption Costing

35 Variable versus Absorption Costing
Depreciation, taxes, insurance and salaries are just as essential to products as variable costs. These are capacity costs and will be incurred even if nothing is produced. Absorption Costing Variable Costing

36 Variable versus Absorption costing
They are the numbers that appear on our external reports. Absorption costing product costs are misleading for decision making. Absorption Costing Variable Costing
