Standard Cost Variance Calculations and Analysis

Conversely, if fewer units were to be produced, this means the amount of overhead allocated on a per-unit basis would be higher. Thus, the designation of the production volume variance as being favorable or unfavorable is only from the accounting perspective, where a lower per-unit cost is considered better.

This method works well with your return on sales ratio, showing the overall change in your net profits, rather than your gross profits. Therefore it’s important to separate out the different aspects of what attributes to your company’s final profit to understand where changes need to be made. Let’s look at the different sales variance formulas and when to use each one. An adverse sales variance could also reveal that your product is overpriced against the competition, or that there’s even a lack of market interest in the product. The determination of overhead expenses is necessary as such costs are of a fixed nature.

And it helps the top management to understand the performance of the production department in achieving long-term targets for the company. It also has other names such as Volume Variance, Denominator Level Variance, or Fixed Overhead Volume Variance. Variable cost-plus pricing is a pricing method whereby the selling price is established by adding a markup to total variable costs. Many production costs are fixed, so higher production means production volume variance formula higher profits. It is easy to simply point at volume as a cause for the additional cost, but as we see in the analysis above, volume is not always the cause. Like an onion, we need to peel away the layers and separate out the causes so that management can better understand fluctuations, ask better questions and make more informed decisions. The gap of $4,800 is the savings generated by creating more units than the budget that is expected.

If the cost of a product is higher or lower in a given period than what was planned, then this higher or lower rate is a Rate Variance. Naturally, more or less units sold will drive COGS up or down accordingly and reflect on the profit and loss statement, which will result in a variance. To determine the key drivers behind the variances, we must first break down the volume sold by product type and analyze both budget and actual. Rate fluctuations happen for a variety of reasons and are typically unexpected. These changes can occur, for example, with increases or decreases in vendor pricing on material purchases or in transportation and warehousing costs. Based on the bill of material , these rates can affect some or all products and have a direct impact on overall costs, which would create a rate variance. The favorable and unfavorable production volume variance along with the limitations have been explained in an easy-to-understand manner.

What causes a volume variance?

A metric known as sales volume variance might be the most practical measure to help you address those points. Total spending on raw materials, transportation of goods, and even storage may vary significantly with greater volumes of production. The logic behind rate variance analysis is simple and requires no special calculations, as we saw above. Using a similar data set below (Illustration B.3) for ABC Canning Co. and using the calculations noted above, we can see mix has an impact on COGS totaling -$228K.

• For example, if a company expected to sell 20 widgets at $100 a piece but only sold 15, the variance is 5 multiplied by $100, or $500.
• Over the next few sections, I will outline how to calculate volume, mix and rate.
• In addition, this extra inventory may become obsolete, which increases the out-of-pocket cost for the business.
• Determine how many units you budgeted for when you planned your sales.
• Applying this mix increase in our mix calculation shows the change in volume impact was -445K units, which we then multiply against the budget rate of $0.57, resulting in our final mix impact of -$252K.

To calculate sales volume variance, subtract the budgeted quantity sold from the actual quantity sold and multiply by the standard selling price. For example, if a company expected to sell 20 widgets https://business-accounting.net/ at $100 a piece but only sold 15, the variance is 5 multiplied by $100, or $500. Because they are fixed within a certain range of activity, these overhead costs are fairly easy to predict.

Calculation of the Production Volume Variance

And it also helps the top-level management to understand whether the production department is working in the direction of long-term goals or not. Moreover, the Denominator Level Variance allocates overhead costs and acts as a balancing tool among budget targets and actual levels. The positive variance shows the efficiency of the production department as well as the production planning process with an overall objective of lowering the costs. As I mentioned, it’s a natural extension of sales volume variance. Management also reconciles the amount of fixed overhead that was allocated to each process with the actual overhead that was incurred for the period. Since the estimates rarely are completely accurate, there is usually a difference between the actual overhead costs incurred during the period and the estimated overhead that was allocated during the period. These differences are considered volume variances because the overhead cost difference occurred as a result of a production volume difference.

• The allocation rate is the expected monthly amount of fixed overhead costs divided by the number of units produced.
• Further investigation of detailed costs is necessary to determine the exact cause of the fixed overhead spending variance.
• You can have a more efficient production process while keeping a steady production level.
• It signifies that the overall cost of production covered a greater number of finished goods or outputs.
• Nevertheless, no matter how many variances exist, the summation of all the variances must equal the total COGS variance.

Fixed CostsFixed Cost refers to the cost or expense that is not affected by any decrease or increase in the number of units produced or sold over a short-term horizon. It is the type of cost which is not dependent on the business activity. In this case, the actual production is less than the budget targets by 100 units, and as a result, there is an additional loss of $1400.

When can fixed overhead volume variance occur?

To analyze further, if there is no volume change, then there is no mix impact, because the sales volume and mix were at planned levels. However, if total volume is the same, but the individual product volume differs from plan (i.e., creating a mix), then there would be no volume impact, but the individual products would have a mix impact. It’s very likely that the impact of a COGS variance is driven by all three components. Over the next few sections, I will outline how to calculate volume, mix and rate. This should help you determine how costs changes are affected by multiple cost drivers. The features/facets of production volume variance have been demonstrated clearly and concisely.

In Accounting from California State University East Bay and an MBA from John F. Kennedy University School of Business. As mentioned previously, all three variances (i.e., volume, mix and rate) can also exist. Nevertheless, no matter how many variances exist, the summation of all the variances must equal the total COGS variance. The chart below (Illustration C.1) illustrates this by showing how the variances for volume, mix and rate total to the COGS variance of $6.7M. Cost of Goods Sold refers to the direct costs of all components used during the manufacturing process. Researching COGS variances without a complete understanding of where to look can lead you down long and time-consuming paths. Calculate the standard profit per unit by subtracting how much it costs to produce each product from the sale price of the product.

Sales Quantity Variance

The expectation is that 3,000 units will be produced during a time period of two months. However, the actual number of units produced is only 2,000, resulting in a total of $50,000 fixed overhead costs.

It’s a figure that essentially tracks an increase or decrease in budgeted profit that stems from the variation between the actual and expected numbers of units sold. Beside from its role as a balancing agent, fixed overhead volume variance does not offer more information from what can be ascertained from other variances such as sales quantity variance. It may be calculated against a budget that was drafted months or even years before actual production. For this reason, some businesses prefer to rely on other statistics, such as the number of units that can be produced per day at a set cost.
