Definition
Sales Margin Mix Variance, also known as Sales Mix Profit Variance, is a variance that arises in standard costing systems. It measures the impact of the change in the actual sales mix compared to the budgeted or standard sales mix on the overall profit. This variance isolates the portion of the total sales volume variance that can be attributed to differences in product mix.
Detailed Explanation
The Sales Margin Mix Variance is calculated as the difference between:
- The actual total sales volume based on the actual mix of products.
- The actual total sales volume based on the budgeted mix of products.
These values are both valued at the standard margin per product. This variance helps businesses understand how changes in the proportion of different products sold affect the profitability compared to what was planned or expected.
Formula
\[ \text{Sales Margin Mix Variance} = (\text{Actual Total Sales Volume} \times \text{Actual Mix} - \text{Actual Total Sales Volume} \times \text{Standard Mix}) \times \text{Standard Margin per Product} \]
Examples
Example 1: A company budgets to sell 100 units of products in the following mix: 60 units of Product A and 40 units of Product B, with standard margins of $5 and $10 per unit, respectively.
However, the actual sales mix is 40 units of Product A and 60 units of Product B, though the total sales volume remains at 100 units.
- Budgeted Sales Mix Profit: (60 units * $5) + (40 units * $10) = $300 + $400 = $700
- Actual Sales Mix Profit: (40 units * $5) + (60 units * $10) = $200 + $600 = $800
The Sales Margin Mix Variance is:
- \( $800 - $700 = +$100 \)
The variance is favorable because the actual sales mix resulted in higher profit margins.
Example 2: Suppose another scenario where the company planned a mix of 50 units of Product A and 50 units of Product B at the same standard margins. Suppose they actually sell 70 units of Product A and 30 units of Product B.
- Budgeted Sales Mix Profit: (50 units * $5) + (50 units * $10) = $250 + $500 = $750
- Actual Sales Mix Profit: (70 units * $5) + (30 units * $10) = $350 + $300 = $650
The Sales Margin Mix Variance is:
- \( $650 - $750 = -$100 \)
The variance is adverse because the actual sales mix resulted in lower profit margins.
Frequently Asked Questions (FAQs)
What is the main purpose of calculating Sales Margin Mix Variance?
The main purpose is to understand the effect of sales mix changes on profitability. It helps in identifying whether a different sales mix has contributed positively or negatively to the overall profit.
How does Sales Mix Profit Variance differ from Sales Volume Variance?
Sales Mix Profit Variance focuses on the impact of the product mix on profit, while Sales Volume Variance looks at the overall effect of changes in sales volumes, irrespective of the mix of products sold.
Can Sales Margin Mix Variance be both favorable and adverse?
Yes, it can be both. A favorable variance indicates the actual sales mix was more profitable than the budgeted mix, whereas an adverse variance signifies the opposite.
