• Selling price: \$120 per unit

• Variable marketing and administrative expenses per unit: \$4
• Fixed marketing and administrative expenses per month: \$1,120,000

Manufacturing costs:

• Direct materials cost per unit: \$30
• Direct labor cost per unit: \$14
• Variable manufacturing overhead cost per unit: \$4
• Fixed manufacturing overhead cost per month: \$1,280,000

Management is anxious to see the success as well as profitability of newly designed unique booster.

Excellent examples. In the one above, under ‘Income reconciliation’ how do you arrive at the figure of \$160,000 for fixed manufacturing overhead cost deferred in inventory?

1. osai

the unit still remain d same for closing stock. however the differences in price in absorption \$80 and variable \$48 =\$32 so \$32×5000=\$160,000.
hope u get d vibs

The number of units in ending inventory is 5,000 and the fixed manufacturing overhead per unit is \$32. Therefore, the fixed manufacturing overhead cost deferred in inventory under absorption costing is \$160,000 as computed below:

5,000 units × \$32* = \$160,000

*1,280,000/40,000

The amount of \$160,000 also represents the cause of difference of net operating income figure under two costing methods. Read this article for details

Hope this helps.

how does absorpton costing happen in service firm,
here is my question
Viti Boutique imports designer clothing manufactured by subcontractors in New Zealand. Clothing is a seasonal product. The goods must be ready for sale prior to the start of the season. Any goods left over at the end of the season usually must be sold at steep discounts. Viti Boutique prepares a dress design and selects fabrics approximately six months before a given season. It receives these goods and distributes them at the start of the season. Based on past experience, Viti Boutique estimates that 60 percent of a particular lot of dresses will be unsold at the end of the season and will be marked down to half of the initial retail price. Even with the markdown, a substantial number of dresses will remain unsold and will be returned to Viti Boutique and destroyed. Although a large number of dresses must be discounted and destroyed, Viti Boutique needs to place a minimum order of 1,000 dresses to have a sufficient selection of styles and sizes to market the design.

Recently, Viti Boutique placed an order for 1,000 dresses of a particular design for \$25,000 plus import duties of \$5,000 and a \$7 commission for each dress sold at retail, regardless of the price. Return mailing and disposing of each unsold dress cost \$3 after the end of the markdown period.

REQUIRED

1. Use absorption costing to compute the cost of each dress in this lot of dresses.

Examples had excellently served me. If variable unit is not specified in the problem, can we use the amount of “selling and administrative” provided under the variable cost per unit?

4. RGP

Units in beginning inventory 300
units produced 1000
units sold 800
units in ending inventory 500
variable cost per unit:
Direct Materials P 1200
Direct Labor P 1400
Fixed cost per year:

Required:
1. Compute the unit costs under absorption and variable costing methods.
2. Compute the operating income under absorption and variable costing methods.
3. Compute the value of ending inventory under absorption and variable costing methods.
4. Reconcile the differences in operating income under the absorption and variable costing methods.

Hi RGP,

Thank you for using accountingformanagement.org Your question is very simple. I think you should be able to easily solve it if you go through all the articles, exercises and problems about variable and absorption costing given in this site:

Hope this helps.

Hello RGP, this explaination on variable and absorption costing methods were perfect, and i understood the illustrations and their solution very well. The illustration given don’t have selling price, and i want to know if it is advisabe to use the per unit production cost as selling price.

7. Accounting For Management

Chukssy Pat is right, RGP has not give selling price and question cannot be solved without it.

what is meant by over absorption of manufacturing cost? where should i put this in income statement under varible cost.?

9. Rasel

I’m having a problem here with absorption costing..
How do we calculate the current units produced if we have units produced in last year.

13. Miss Quinto

Els co. had net income for the first 10 months of the current year of P200000. They used standard costing system and there were no variances through Oct 31. 100000 units were manufactured and old during the period. There are no selling and administrative expense. Both variable and fixed costs are expected to continue at the same rates for the balance of the year, fixed cost at P200000 per month and variable cost at the same variable cost per unit. there were 10000 units in inventory on October 31. 18000 units are to be produced and 22000 units are to be sold in total over the last 2 months of the current year. Assume that the standard unit variable cost is the same as in the previous year.

Required:
1. if operations proceed as described, what will net income for the year in total be under variable costing? absorption costing?

Ignore income taxes.

Kindly answer this problem. I really need it. Thank you.
