Variances are calculated and reported at regular intervals to ensure the quick remedial actions against any unfavorable occurrence. Where,
SQ is the standard quantity allowed,
AQ is the actual quantity of direct material used, and
SP is the standard price per unit of direct material. An adverse or unfavorable material quantity variance occurs when the actual volume of materials used in production exceeds the standard quantity that is expected for the level of output in a period.
You’ll have a truer sense of your company’s total manufacturing costs when you properly account for variances in price, quantity, and efficiency. Premium Furniture, a US based Inc., uses a standard costing system to control its direct materials and conversion costs. During the month of December 2022, its workers used 3,750 feet of timber to finish 1,500 office chairs. The standard length of timber allowed to manufacture an office chair is 2.75 feet and the standard rate per foot of timber is $3.50. How much is the direct materials quantity variance of Prime Furniture Inc. for the month of December 2022?
- The material quantity is usually set by the engineering department, and is based on an expected amount of material that should theoretically be used in the production process, along with an allowance for a reasonable amount of scrap.
- If workers manufacture a certain number of units using a quantity of materials that is less than the quantity allowed by standards for that number of units, the variance is known as favorable direct materials quantity variance.
- Like direct materials price variance, this variance may be favorable or unfavorable.
- The material quantity variance can yield unusual results, since it is based on a standard unit quantity that may not be even close to actual usage.
Subtracting from that the product of the Standard Quantity of raw materials (AQ) and the Standard Cost (SC) would give the total expected cost of materials if the conversion process used those materials exactly as expected. A number of parties may be held responsible for an unfavorable quantity variance (or take credit for a favorable variance!). For example, the scrapping of a number of units in the production process may mean that the quality of incoming components was inadequate, which could be the problem of the purchasing department. Conversely, the same level of scrap may be caused by improper equipment setup, which is the responsibility of the industrial engineering staff. Or, the issue may be caused by improper training of the production staff, which is an issue for the production manager.
As is the case when analyzing other variances, the direct material price variance needs to be assessed in the context of other relevant variances and factors, such as direct material price variance and direct labor variances. The management therefore needs to assess performance while taking all these relevant factors into account. With either of these formulas, the actual quantity used refers to the actual amount of materials used at the actual production output.
You’re most likely to run into an unfavorable materials quantity variance because of one of the following issues. The above material quantity variance formula has the following components. Similarly, poorer quality materials may be more difficult to work with; this may lead to an adverse labour efficiency variance as the workforce takes longer than expected to complete the work. Looking at the individual variances, Gamma has a very small favourable variance.
What is the formula to calculate material variances?
Figure 10.35 shows the connection between the direct materials price variance and direct materials quantity variance to total direct materials cost variance. Figure 8.3 shows the connection between the direct materials price variance and direct materials quantity variance to total direct materials cost variance. 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. Generally, the production managers are considered responsible for direct materials quantity variance because they are the persons responsible for keeping a check on excessive usage of production inputs. However, purchase managers may purchase low quality, substandard or otherwise unfit materials with an intention to improve direct materials price variance. In such cases, the responsibility of any unfavorable quantity variance would lie on the purchasing department.
Ignore how much you actually paid for raw materials; we’re just trying to quantify the actual vs. expected quantity. To evaluate the price difference, you’re looking for a different accounting formula called the direct material price variance. Don’t immediately blame inferior raw materials or your factory workers for an unfavorable materials quantity variance.
When you calculate the variance, you’re comparing actual material usage to what you expected. It could be that the expectation you created in the product development process is askew. A quantity variance is the difference between the actual usage of something and its expected usage. For example, if a standard quantity of 10 pounds turbotax official site of iron is needed to construct a widget, but 11 pounds are actually used, then there is a quantity variance of one pound of iron. The variance typically applies to direct materials in the manufacture of a product, but it could apply to anything – the number of hours of machine time used, square footage used, and so on.
If the standard is excessively generous, there will be a long series of favorable material quantity variances, even though the production staff may not be doing an especially good job. Conversely, a parsimonious standard allows little room for error, so there is more likely to be a considerable https://intuit-payroll.org/ number of unfavorable variances over time. Thus, the standard used to derive the variance is more likely to cause a favorable or unfavorable variance than any actions taken by the production staff. In a question, use either the usage variance or the mix and yield variances.

From this it can be seen that the more Beta used, the more expensive the final product will be. You can check this video of mine for more examples of the material quantity variance. Now that we know the standard quantity, we can use the DMQV formula to calculate the variance.
Responsibility for Quantity Variances
In many production processes, it may be possible to combine different levels (use a different mix) of the input materials to make the same product. This, in turn, may result in differing yields, depending on the mix of materials that has been used. This year, Band Book made 1,000 cases of books, so the company should have used 28,000 pounds of paper, the total standard quantity (1,000 cases x 28 pounds per case). However, the company purchased 30,000 pounds of paper (the actual quantity), paying $9.90 per case (the actual price).

Material quantity variance represents the difference between the actual and standard quantities of material used for a specific product. Material quantity variance is crucial for companies to control costs and adhere to defined standards. Standard direct material usage refers to the amount of materials allowed to be used per unit produced. The actual quantity in the actual mix is given in the question, as are the standard costs.
