Question

Problem 18.31
Contribution Margin Variance, Contribution Margin Volume Variance, Sales Mix Variance

Haysbert Company provides management services for apartments and rental units. In general, Haysbert packages its services into two groups: basic and complete. The basic package includes advertising vacant units, showing potential renters through them, and collecting monthly rent and remitting it to the owner. The complete package adds maintenance of units and bookkeeping to the basic package. Packages are priced on a per-rental unit basis. Actual results from last year are as follows:

Explanation / Answer

1.

Contribution margin variance = Actual contribution margin – Budgeted contribution margin

Contribution margin = Sales – Variable expenses

Actual contribution margin

Basic

Complete

Selling price

$140

$300

Variable expenses

$85

$240

Contribution margin per unit

$55

$60

Sales units

2000

400

Contribution margin

$110,000

$24,000

Actual contribution margin = $110,000 + $24,000 = $134,000

Budgeted Contribution margin

Basic

Complete

Selling price

$145

$290

Variable expenses

$90

$242

Contribution margin per unit

$55

$48

Sales units

1950

460

Contribution margin

$107,250

$22,080

Budgeted Contribution margin = $107,250 + $220,80 = $129,330

Contribution margin variance = $134,000 - $129,330 = $4,670 F

2.

Budgeted sales units = 1950 + 460 = 2410 rental units

Budgeted contribution margin = $129,330

Budgeted average contribution margin per unit = $129,330 / 2410 = $53.6639

Actual sales units = 2000 + 400 = 2410 rental units

Contribution margin volume variance = (Actual sales unit – Budgeted sales unit)*Budgeted CM per unit

= (2000 – 2410)* $53.6639 = $22,002.20 U

This unfavorable variance shows that the actual contribution margin is less than budgeted contribution margin because of sales units.

3.

Basic sales mix data = (2000 – 1950)($55 - $53.6639) = $66.81 F

Complete sales mix data = (400 – 460)($48 - $53.6639) = $339.83 F

Sales mix variance = $66.81 F + $339.83 F = $406.64 F
