Direct Materials Quantity Variance: Definition

Direct materials quantity variance is a part of the overall materials cost variance that occurs due to the difference between the actual quantity of direct materials used and the standard quantity allowed for the output.

Direct materials quantity variance is also known as direct material usage or volume variance. It indicates whether or not the material has been properly utilized.

A favorable materials quantity variance indicates savings in the use of direct materials. An unfavorable variance, on the other hand, indicates that the amount of materials used exceeds the standard requirement.

Frequently Asked Questions

How is the direct material quantity variance calculated?

The direct materials quantity variance can be calculated as follows: Quantity of Direct Materials Used (4,000 units) – Standard Quantity Allowed (4,200 units) = Direct Material Quantity Variance (200 units unfavorable)

If a company's actual quantity used exceeds the standard allowed, what would the variance be?

If a company's actual quantity used exceeds the standard allowed, then the direct materials quantity variance will be unfavorable. This means that the company has utilized more materials than expected and may have paid extra in materials cost.

How is direct material usage variance calculated in a multi-product company?

In a multi-product company, the total quantity variance is divided over each of the products manufactured. This will result in a product usage variance for each unit produced.

What is meant by standard direct material usage?

Standard direct material usage refers to the amount of materials allowed to be used per unit produced. It may also refer to the amount expected under normal circumstances.

How is direct materials price variance calculated?

A direct materials price variance can be calculated as follows: Actual Direct Materials Price (per unit) – Standard Direct Materials Price (per unit) = Direct Materials Price Variance (Unfavorable or Favorable)
