What is Direct Material Price Variance?
Direct Material Price Variance (DMPV) is a measure used in cost accounting to determine the difference between what was actually paid for raw materials and what should have been paid based on standard (budgeted) costs. It helps businesses identify whether their purchasing department is performing above or below expectations.
This variance is a critical component of standard costing systems and variance analysis, enabling companies to identify cost overruns or savings in their procurement processes.
The Direct Material Price Variance Formula
The formula for calculating direct material price variance is straightforward:
Or expressed as:
DMPV = (AP - SP) × AQ
Where:
AP = Actual price per unit of material
SP = Standard (budgeted) price per unit
AQ = Actual quantity purchased
Interpreting the Results
Unfavorable Variance (Positive)
When actual price > standard price
- Company paid more than budgeted
- Increases production costs
- May require investigation
- Could indicate supplier issues, market changes, or poor negotiation
Favorable Variance (Negative)
When actual price < standard price
- Company paid less than budgeted
- Decreases production costs
- Generally positive outcome
- May indicate good negotiation, bulk discounts, or market conditions
Example Calculation
Let's work through a practical example:
Scenario: A furniture manufacturer budgeted to purchase lumber at $10.00 per board foot. They actually paid $12.50 per board foot for 5,000 board feet.
Actual Price (AP) = $12.50
Standard Price (SP) = $10.00
Actual Quantity (AQ) = 5,000 units
Step 2: Calculate the variance
DMPV = (AP - SP) × AQ
DMPV = ($12.50 - $10.00) × 5,000
DMPV = $2.50 × 5,000
DMPV = $12,500 Unfavorable
Interpretation: The company spent $12,500 more on lumber than budgeted due to the higher price. This is an unfavorable variance that warrants investigation.
Causes of Material Price Variance
Causes of Unfavorable Variance
- Market price increases: General inflation or supply shortages
- Rush orders: Paying premium for expedited delivery
- Small order quantities: Losing bulk discounts
- Quality upgrades: Purchasing higher-grade materials
- Supplier changes: Using more expensive vendors
- Poor negotiation: Failing to secure competitive prices
- Transportation costs: Higher shipping or handling fees
Causes of Favorable Variance
- Bulk purchasing: Volume discounts from larger orders
- Market price decreases: Deflation or increased supply
- Better negotiation: Securing competitive bids
- New suppliers: Finding lower-cost vendors
- Early payment discounts: Cash discounts for prompt payment
- Long-term contracts: Locking in favorable prices
Management Actions Based on Variance
| Variance Type | Investigation Triggers | Possible Actions |
|---|---|---|
| Large Unfavorable | Exceeds materiality threshold (e.g., >5%) | Review supplier contracts, seek alternative vendors, verify quality requirements |
| Small Unfavorable | Within acceptable range | Monitor trends, update standards if market has shifted |
| Small Favorable | Within acceptable range | Document savings, consider updating standards |
| Large Favorable | Exceeds expectations significantly | Verify quality is maintained, investigate sustainability, consider locking in prices |
Price Variance vs. Quantity Variance
Material variance analysis typically includes two components:
Price Variance = (Actual Price - Standard Price) × Actual Quantity
Quantity Variance = (Actual Quantity - Standard Quantity) × Standard Price
This separation allows management to identify whether cost overruns are due to:
- Price Variance: Paying more/less per unit (purchasing department responsibility)
- Quantity Variance: Using more/less material than expected (production department responsibility)
Strategies to Improve Material Price Variance
- Develop Strong Supplier Relationships: Build partnerships that encourage favorable pricing and reliable supply
- Implement Competitive Bidding: Regularly request quotes from multiple suppliers
- Consider Long-Term Contracts: Lock in prices when market conditions are favorable
- Optimize Order Quantities: Balance bulk discounts against storage costs
- Monitor Market Trends: Anticipate price changes and adjust purchasing strategies
- Review Material Specifications: Ensure you're not over-specifying requirements
- Explore Alternative Materials: Consider substitutes that meet quality needs at lower cost
- Improve Forecasting: Better demand planning enables more strategic purchasing

Frequently Asked Questions
Price variance is typically calculated at the time of purchase, not when materials are used. This allows for timely identification of purchasing performance issues. Many companies calculate it monthly as part of their management accounting routine.
The threshold varies by company and industry. Common approaches include: investigating variances exceeding a dollar threshold (e.g., $5,000), a percentage threshold (e.g., 5% of standard cost), or using statistical process control limits. The key is consistency in applying your chosen threshold.
Standards are typically reviewed annually as part of the budgeting process. However, in volatile markets, more frequent updates may be necessary. If persistent variances occur, it may indicate that standards are outdated rather than actual purchasing problems.
The purchasing department is typically held responsible for price variances since they negotiate with suppliers and make buying decisions. However, production may bear some responsibility if rush orders or specification changes contributed to higher prices.
Yes. A favorable price variance might result from purchasing lower-quality materials that could cause production problems, increased scrap, or customer complaints. Always investigate significant favorable variances to ensure quality standards are maintained.
