Understanding Direct Materials Usage Variance
Direct Materials Usage Variance is a crucial metric in cost accounting that assesses the difference between the actual quantity of materials used in production and the standard quantity that should have been used, multiplied by the standard cost per unit of material. This variance helps management understand how efficiently they are utilizing materials and can highlight areas where waste or inefficiency is occurring.
The formula to calculate Direct Materials Usage Variance is:
1Direct Materials Usage Variance = (Actual Quantity Used - Standard Quantity Allowed) × Standard Cost per Unit
Examples
-
Example 1:
A company sets a standard of 5 kg of raw material to produce one unit of product. The standard cost is $10 per kg. If the company actually uses 520 kg of materials to produce 100 units, the variance would be calculated as follows:
- Standard Quantity Allowed = 100 units × 5 kg/unit = 500 kg
- Actual Quantity Used = 520 kg
- Standard Cost per Unit = $10/kg
1Direct Materials Usage Variance = (520 kg - 500 kg) × $10/kg = 20 kg × $10/kg = $200 unfavorable
-
Example 2:
For a batch of products that typically should use 300 meters of fabric at a cost of $6 per meter, if only 280 meters are used, the variance is:
- Standard Quantity Allowed = 300 meters
- Actual Quantity Used = 280 meters
- Standard Cost per Unit = $6/meter
1Direct Materials Usage Variance = (280 meters - 300 meters) × $6/meter = -20 meters × $6/meter = $120 favorable
Frequently Asked Questions (FAQs)
Q: What causes Direct Materials Usage Variance?
- A: Several factors can lead to variance, including inefficient material use, theft, spoilage, changes in production processes, and errors in setting the standard quantity.
Q: How can a company reduce unfavorable Direct Materials Usage Variances?
- A: Companies can improve variance by training employees, improving inventory management, maintaining equipment, preventing theft, and constantly reviewing and updating standards based on actual results.
Q: Is a favorable Direct Materials Usage Variance always good?
- A: While a favorable variance indicates efficient use of materials, it could also mean that the standard was set too loosely, potentially leading to a decrease in product quality.
Standard Quantity Allowed:
- The expected amount of materials required to produce a specific number of units, based on established standards.
Standard Cost:
- The predetermined cost per unit of material used in production, based on budgeted or planned expenses.
Material Price Variance (MPV):
- The variance that arises due to the difference between the actual price paid for materials and the standard cost expected to be paid.

### A company has a standard material usage of 100 kg for a batch, but they actually used 110 kg at a standard cost of $5 per kg. What is the Direct Materials Usage Variance?
- [ ] $50 favorable
- [ ] $50 neutral
- [x] $50 unfavorable
- [ ] $500 unfavorable
> **Explanation:** The variance would be (110 kg - 100 kg) × $5/kg = 10 kg × $5/kg = $50 unfavorable.
