Direct materials are a significant cost component for most businesses. Managers regularly assess the difference in value between the raw materials' purchase price and their utilization in production. This study explores the concept of direct materials variance analysis, which involves assessing the variance in direct materials costs. The report discusses how accountants calculate direct materials variance and its components, with a practical example illustrating its application.
The direct materials variance analysis comprises various components:
Before diving into the calculations, it's essential to understand the key terms involved in direct materials variance analysis:
Accountants use variance calculations to determine the total direct materials variance.
The formulae for the key components are as follows:
| Component | Formula |
|---|---|
| Direct Materials Purchased | AQ × AP |
| Direct Materials Inventory | AQ × SP |
| Direct Materials Price Variance | (AQ × AP) - (AQ × SP) |
| Direct Materials Quantity Variance | (AQ × SP) - (SQ × SP) |
Where:
The total variance is the sum of the price variance and the quantity variance:
| Total Variance | Price Variance + Quantity Variance |
|---|
Let's apply the concept of direct materials variance analysis to a furniture maker's scenario.

The company previously purchased wood for making tables at $4.00 per yard but found a deal to buy it at $3.75 per yard instead. The production plan was to make 1,100 units, but due to the new, harder-to-work-with wood, only 1,000 units were produced. We will calculate whether the total variance is favorable or unfavorable.
| Component | Actual at Actual | Actual at Standard | Standard at Standard |
|---|---|---|---|
| Actual Quantity | 1,000 | 1,000 | 1,100 |
| Actual Price | $3.75 | $4.00 | $4.00 |
| Total | $3,750 | $4,000 | $4,400 |
The direct materials variance calculations include price and quantity variances:
Direct Materials Price Variance:
($3,750) - ($4,000) = -$250 or $250 Favorable
This equation shows that the actual amounts are $250 better than the predicted amounts. The formula gives the actual quantity at actual price minus the actual quantity at standard price.
Direct Materials Quantity Variance:
($4,000) - ($4,000) = -$400 Favorable
This equation gives the actual quantity at standard price minus the standard quantity at standard price. Note that the sign of the variance is not important; favorability or unfavorability is the key. This means there is a total favorable variance of $650.
Favorable Change = $250 + $400 = $650
This represents the difference between the actual cost at actual price and the standard cost at standard price. Despite the cheaper wood, the overall variance is favorable, indicating that the purchasing manager's decision was a good one.
In conclusion, direct materials variance analysis is a crucial tool for businesses to assess and manage their direct materials costs. By calculating price and quantity variances, companies can make informed decisions about their material procurement strategies. In the case of the furniture maker, even though cheaper wood was used, the overall variance was favorable, demonstrating the importance of considering both price and quality when making purchasing decisions. This analysis aids managers and accountants in controlling costs and optimizing production processes.
