Learning Objective 6 Subdivide the sales-volume variance into the sales-mix variance and the sales-quantity variance and the sales-quantity variance into the market-share variance and the market-size variance
The customer-profitability analysis in the previous section focused on the actual profitability of individual customers within a distribution channel (wholesale, for example) and their effect on the Provalue Division’s profitability for 2019. At a more strategic level, however, recall that Provalue Division sells Provalue in two different markets: wholesale and directly to businesses. The operating margins in the business-sales market are higher than the operating margins in the wholesale market. In 2019, the Provalue Division had budgeted to sell 60% of Provalue through wholesalers and 40% directly to businesses. It sold fewer Provalue computers in total than it had budgeted, and its actual sales mix (in computers) was 66.67% to wholesalers and 33.33% directly to businesses. Regardless of the profitability of sales to individual customers within each of the wholesale and business-sales channels, the Provalue Division’s actual operating income, relative to the master budget, is likely to be negatively affected by the lower number of Provalue computers sold and the shift in mix toward the less profitable wholesale customers. Sales-quantity and sales-mix variances can identify the effect of each of these factors on the Provalue Division’s profitability. Companies such as Cisco, GE, and Hewlett-Packard perform similar analyses because they sell products through multiple distribution channels like the Internet, the telephone, and retail stores.
The Provalue Division classifies all customer-level costs, other than fixed machining costs of $11,400,000, as variable costs and all distribution-channel, division-sustaining, and corporate-sustaining costs as fixed costs. To simplify the sales-variance analysis and calculations, we assume that variable costs vary with the number of Provalue computers sold. (This means that average batch sizes remain the same as the total number of Provalue computers produced and sold change.) Without this assumption, the analysis becomes more complex and needs to be done using the ABC-variance analysis approach described in Chapter 8. The basic insights, however, do not change.
Budgeted and actual operating data for 2019 are as follows:

The table depicts selling price, variable cost per unit, contribution margin per unit, sales volume in units, sales mix (based on units), and contribution margin for wholesale channel and business-sales channel as well as totals. The details of the table are as follows:
1. Wholesale channel
2. Business-sales channel
3. Total

The table depicts selling price, variable cost per unit, contribution margin per unit, sales volume in units, sales mix (based on units), and contribution margin for wholesale channel and business-sales channel as well as totals. The details of the table are as follows:
The budgeted and actual fixed distribution-channel costs, division costs, and corporate-level costs are the same (see Exhibit 15-6 and Exhibit 15-7).
Recall that the levels of detail introduced in Chapter 7 included the static-budget variance (level 1), the flexible-budget variance (level 2), and the sales-volume variance (level 2). The sales-quantity and sales-mix variances discussed in this chapter are level 3 variances that subdivide the sales-volume variance.*
The static-budget variance is the difference between an actual result and the corresponding budgeted amount in the static budget. Our analysis focuses on the difference between actual and budgeted contribution margins (column 6 in the preceding tables). The total static-budget variance is $2,125,000 unfavorable variance (U) (actual contribution margin of Exhibit 15-11 (columns 1 and 3) uses the columnar format introduced in Chapter 7 to show detailed calculations of the static-budget variance. Managers can gain more insight about the static-budget variance by subdividing it into the flexible-budget variance and the sales-volume variance.
