Estimated Income Statements, using Absorption and Variable Costing

Prior to the first month of operations ending October 31 Marshall Inc. estimated the following operating results:

Sales (21,600 x $75)	$1,620,000
Manufacturing costs (21,600 units):
Direct materials	984,960
Direct labor	233,280
Variable factory overhead	108,000
Fixed factory overhead	129,600
Fixed selling and administrative expenses	35,300
Variable selling and administrative expenses	42,600

The company is evaluating a proposal to manufacture 24,000 units instead of 21,600 units, thus creating an Inventory, October 31 of 2,400 units. Manufacturing the additional units will not change sales, unit variable factory overhead costs, total fixed factory overhead cost, or total selling and administrative expenses.

a. 1. Prepare an estimated income statement, comparing operating results if 21,600 and 24,000 units are manufactured in the absorption costing format. If an amount box does not require an entry leave it blank or enter 0.

b. What is the reason for the difference in income from operations reported for the two levels of production by the absorption costing income statement?

The increase in income from operations under absorption costing is caused by the allocation of fixed factory overhead cost over a larger number of units. Thus, the cost of goods sold is less . The difference can also be explained by the amount of fixed factory overhead cost included in the ending inventory.
