What is Purchase Price Variance (PPV) ?

Purchase Price Variance (PPV) is a measure used in cost accounting to quantify the difference between the standard cost of materials specified for production and the actual cost paid to acquire those materials. It’s a key indicator of how efficiently materials are being procured and managed within a manufacturing process.

Here’s a breakdown of Purchase Price Variance:

Calculation of PPV:

The formula for Purchase Price Variance (PPV) is typically:

PPV=(Standard Price−Actual Price)×Actual Quantitytext{PPV} = (text{Standard Price} – text{Actual Price}) times text{Actual Quantity}PPV=(Standard Price−Actual Price)×Actual Quantity

• Standard Price: The predetermined cost per unit of material established by the company’s standard costing system. This is often based on historical data, negotiated prices, or estimates.

• Actual Price: The actual price per unit paid for the materials purchased.

• Actual Quantity: The actual quantity of materials purchased.

Interpretation of PPV:

• Positive PPV: Indicates that materials were purchased at a lower cost than the standard price. This is generally favorable, as it reduces the cost of goods sold and can positively impact profitability.

• Negative PPV: Indicates that materials were purchased at a higher cost than the standard price. This is unfavorable and can suggest inefficiencies in purchasing, supplier management, or unexpected price increases.

Factors Affecting PPV:

1. Changes in Material Costs: Fluctuations in raw material prices due to market conditions, inflation, currency exchange rates, etc.

2. Supplier Performance: Variations in supplier pricing, discounts, rebates, and shipping costs.

3. Quality of Materials: Higher-quality materials may come at a premium cost, affecting PPV.

4. Volume Discounts: Failure to achieve volume discounts or changes in order quantities can impact PPV.

5. Delivery Delays or Expedited Shipping: Additional costs incurred due to delays or expedited shipping methods can affect PPV.

Importance of PPV:

• Cost Control: PPV analysis helps identify opportunities for cost savings and cost control measures.

• Supplier Management: It provides insights into supplier performance and helps in negotiating better terms with suppliers.

• Budgeting and Forecasting: Helps in refining future cost estimates and budget planning.

• Continuous Improvement: Identifies areas for process improvement and efficiency gains within the procurement process.

Example:

Let’s say a company’s standard cost for a particular raw material is $10 per unit, but due to market fluctuations, they ended up paying $12 per unit for 500 units of the material. The PPV would be calculated as:

PPV=($10−$12)×500=(−$2)×500=−$1,000text{PPV} = ($10 – $12) times 500 = (-$2) times 500 = -$1,000PPV=($10−$12)×500=(−$2)×500=−$1,000

In this case, the negative PPV of $1,000 indicates that the company paid $1,000 more for the material than expected based on standard costs, which could prompt further investigation into the reasons behind the variance and actions to mitigate it in the future.
