Answer:
a) Contribution margin is $360,000 and Net income is $101,250.
b) The portion of sales revenue that is not used to pay variable costs is $360,000. That is, the portion of the sales revenue that is left to pay for fixed costs and make a profit is $360,000.
c) The percentage of sales revenue that is left after deducting all the variable costs is 72%. In other words, 72% of sales revenue is left to pay for fixed costs and make a profit.
Explanation:
These can be calculated as follows:
a) Prepare a contribution margin income statement
Tight Drums Company
Contribution margin income statement
For the year ended December 31, 2015
Particulars $ $
Sales revenue (1,000 * $500) 500,000
Variable costs
Plastic for casing (17,000)
Wages of assembly workers (82,000)
Drum stands (26,000)
Sales commissions (15,000)
Total variable cost (140,000)
Contribution margin 360,000
Fixed costs
Taxes on factory (5,000)
Factory maintenance (10,000)
Factory machinery depreciation (40,000)
Lease of equip. for sales staff (10,000)
Accounting staff salaries (35,000)
Admin. management salaries (125,000)
Total Fixed cost (225.000)
Income before tax 135,000
Tax (135,000 * 25%) (33,750)
Net income 101,250
b) Interpret the contribution margin
Contribution margin is sales revenue minus total variable cost.
From part a, contribution of $360,000 therefore implies that the portion of sales revenue that is not used to pay the variable costs is $360,000.
That is, the portion of the sales revenue that is left to pay for fixed costs and make a profit is $360,000.
c) Interpret the contribution margin ratio
Contribution margin ratio = Contribution margin / Sales revenue = $360,000 / $500,000 = 0.72, or 72%
This implies that 72% of sales revenue is left after deducting all the variable cost. In other words, 72% of sales revenue is left to pay for fixed costs and make a profit.
