Variable cost of goods sold

Variable cost of goods manufactured $9,280,000

Ending Inventory                                    $928,000

Variable cost of goods sold                                        $8,352,000

Manufacturing margin                                                  $2,448,000

Variable selling and administrative                             $1,080,000

expenses

Contribution margin                                                     $1,368,000

Fixed Cost:

Fixed manufacturing cost                        $320,000

Fixed selling and administrative              $180,000

expenses

Total fixed cost                                                                $500,000

Income from operation                                                  $868,000

3. The reason for difference of amount for income from operation is $32,000 ($900,000 - $868,000). It is due to fixed manufacturing cost which is included for ending inventory under absorption costing (320,000 / 80,000 * 8,000). Hence, income under absorption costing is higher by $32,000 as compared to income under variable costing.
