Explanation of Solution

Income statement under absorption costing when 300 workstations are produced is,

    S.R. Company Income Statement (Absorption Costing) For the year ended 2018
    Particulars Amount ($) Amount($)
    Sales ( 300×$3,000 ) 900,000
    Cost of Goods sold (working note) (414,000)
    Gross Margin 486,000
    Variable Selling and Administrative Cost ( 300×$50 ) (15,000)
    Fixed Selling and Administrative Cost (4,000) (19,000)
    Net Income 467,000
    Table (1)

The net income under absorption costing at 300 units of production is $467,000.

Working note:

Calculation of cost of goods sold is,

    Cost of Goods Sold=Number of Units Sold×Cost Per Unit

Where, the cost per unit can be calculated as,

    Particulars Amount ($) Per Unit
    Direct Materials 800
    Direct Labor 400
    Variable Overheads 100
    Fixed Overheads ( $24,000 300 ) 80
    Total Cost Per Unit 1,380
    Table (2)

Substitute 300 for the number of units and $1,380 for the cost per unit in the above formula.

    Cost of Goods Sold=300×$1,380 =$414,000

Thus, the net income under absorption costing at 300 units of production is $467,000.

Solution:

Income statement under absorption costing when 320 workstations are produced is,

    S.R. Company Income Statement (Absorption Costing) For the year ended 2018
    Particulars Amount ($) Amount($)
    Sales ( 300×$3,000 ) 900,000
    Cost of Goods sold (working note) (412,500)
    Gross Margin 487,500
    Variable Selling and Administrative Cost ( 300×$50 ) (15,000)
    Fixed Selling and Administrative Cost (4,000) (19,000)
    Net Income 468,500
    Table (3)

The net income under absorption costing at 320 units of production is $468,500.

Working note:

Calculation of cost of goods sold is,

    Cost of Goods Sold=Number of Units Sold×Cost Per Unit

Where, the cost per unit can be calculated as,

    Particulars Amount ($) Per Unit
    Direct Materials 800
    Direct Labor 400
    Variable Overheads 100
    Fixed Overheads ( $24,000 320 ) 75
    Total Cost Per Unit 1,375
    Table (4)

Substitute 300 for the number of units and $1,375 for the cost per unit in the above formula.

    Cost of Goods Sold=300×$1,375 =$412,500

Thus, the net income under absorption costing at 320 units of production is $468,500.

    Direct Labor ( 300×$400 ) (120,000)
    Variable production Overhead ( 300×$100 ) (30,000)
    Variable Selling and Administrative Cost ( 300×$50 ) (15,000) (405,000)
    Contribution Margin 495,000
    Fixed Production Overhead (24000)
    Fixed Selling and Administrative Cost (4,000) (28,000)
    Net Income 467,000

Explanation of Solution

  • The income statement prepared under variable costing includes the costing of a product on only direct or variable cost, so, the valuation of the ending inventory is done only on variable cost and not on the fixed cost.
  • The income statement prepared under absorption costing includes the costing of a product on both fixed and variable costs, so, the valuation of the ending inventory is done on both the cost that is fixed and variable.
  • The difference in the value of the closing inventory creates the difference in the incomes under the absorption and variable method.
  • When the value of closing inventory becomes zero or same under both methods, the difference between their incomes becomes zero. So, the difference in income between the variable costing and absorption costing is due to the difference in the value of closing inventory under both the methods.
  • From the calculation above in part 1 and 2 it can be seen that the income is greater when the company produces 320 units and uses the absorption costing, so, the company should take the income as the measure to take decision regarding production.

Thus, the difference in income between the variable costing and absorption costing is due to the difference in the value of closing inventory under both the methods and the company can take the production decision by looking at the income figures under the two methods.
