1. The Wilcox Company sells two products, A and B, with contribution margin ratios of 40 and 30 percent and selling prices of $5 and $2.50 a unit. Fixed costs amount to $72,000 a month. Monthly sales average 30,000 units of product A and 40,000 units of product B.
Required:
a.
Assuming that three units of product A are sold for every four units of product B, calculate the dollar sales volume necessary to break even.
b.
As part of its cost accounting routine, Wilcox Company assigns $36,000 in fixed costs to each product each month. Calculate the break-even dollar sales volume for each product.
c.
Wilcox Company is considering spending an additional $9,700 a month on advertising, giving more emphasis to product A and less emphasis to product B. If its analysis is correct, sales of product A will increase to 40,000 units a month, but sales of product B will fall to 32,000 units a month. Recalculate the break-even sales volume, in dollars, at this new product mix. Should the proposal to spend the additional $9,700 a month be accepted?
Answer
a. Sales mix = 3 units of A : 4 units of B
So, as mentioned in the question, 30,000 units of product A and 40,000 units of product B can be taken as sales mix.
Break even dollar sales volume is asked here.
Break even dollar sales volume = Fixed cost / Contribution margin ratio
Since, there are two kinds of products, we can't consider the contribution margin ratio of a single product. We should calculate weighted average contribution margin ratio. Here is the workings:
Product A | Product B | Total | ||
Number of units | 30,000 | 40,000 | 70,000 | |
Selling price per unit | $5 | $2.5 | ||
Total sales | Number of units*selling price | 30,000*5 = $150,000 | 40,000*2.5 = $100,000 | $250,000 |
Contribution margin ratio | 40% | 30% | ||
Total contribution margin | Total sales*contribution margin ratio | 150,000*40% = $60,000 | 100,000*30% = $30,000 | $90,000 |
So, total contribution margin for product A $ B = $90,000
Weighted average contribution margin ratio = Total contributon margin / total sales = 90,000/250,000 = 0.36 or 36%
fixed cost = $72,000
So, break even dollar sales volume = 72,000 / 0.36 = $200,000
b. Break even dollar sales volume for each product
Product A | Product B | |
Contribution margin ratio | 40% or 0.4 | 30% or 0.3 |
Fixed cost = $36,000 for each product
Break even dollar sales volume = fixed cost / contribution margin ratio
1. For product A = 36,000 / 0.4 = $90,000
2. For product B = 36,000 / 0.3 = $120,000
c.If advertising is adopted, fixed cost will increase by $9,700
Sales mix also changed. Let's calculate new weighted average contribution margin ratio.
Product A | Product B | Total | ||
Number of units | 40,000 | 32,000 | 72,000 | |
Selling price | $5 | $2.5 | ||
Total sales | seling price*number of units | 5*40,000 = $200,000 | 2.5*32,000 = $80,000 | $280,000 |
Contribution margin ratio (contribution margin ratio for individual products won't change) |
40% | 30% | ||
Total contribution margin | Total sales*contribution margin ratio | 200,000*40% = $80,000 | 80,000*30% = $24,000 | $104,000 |
Weighted contribution margin ratio = Total contribution margin / total sales = 104,000/280,000 = 0.3717 or 37.14%
Fixed cost = 72,000 + 9,700 = $81,700
Break even sales volume in dollars = 81,700 / 0.3714 = $219,978
Decision on advertising proposal
The break even sales volume in dollars was $200,000 before accepting this proposal. But after accepting this, it has increased to $219,978, which means the company has to increase it's sales by $19,978 to attain the break even(or to attain no profit no loss condition). But due to advertising, the gross sales has increased from $250,000 to $280,000. An increase of $30,000 sales is enough to compensate the increase in break even sales of $19,978. SO, THE ADVERTISING PROPOSAL CAN BE ACCEPTED.
