  • Now we’re getting into fixed overhead variance analysis, which is different.

Variance analysis can be summarized as an analysis of the difference between planned and actual numbers. The sum of all variances gives a picture of the overall over-performance or under-performance for a particular reporting period. For each item, companies assess their favorability by comparing actual costs to standard costs in the industry. 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.

Favorable Production Volume Variance

Remember we are trying to explain the impact of Sales variances on profit margin, not total Sales $. If we had taken Selling price instead of Profit margin, we would be explaining Sales $ variance (change in Sales $ from 2017 to 2018), but we are calculating the impact on Profit margin. For each increase or decrease in unit sold vs last year, the profit margin will be impacted only by the amount of profit margin per unit and not the total Sales value.

  • This is because the responsibility for overhead costs is difficult to pin down.
  • The graph below (Illustration D.1) also represents the variance impacts of volume, mix and rate by demonstrating a “variance walk” from plan to actual.
  • It also allows you to decompose the volume and pricing performances by product type between budgets and actual values.
  • From the data available, you can easily calculate the selling price per unit of each fruit (Amount of Sales ($) for each fruit sold divided by the number of units sold).
  • The company can calculate fixed overhead volume variance with the formula of standard fixed overhead applied to actual production deducting the budgeted fixed overhead.

To calculate the production volume variance, we deduct the budgeted unit of production from the actual number of units produced. When actual production is lower than budgeted production, production volume variance is unfavorable. Production volume variance is a statistic used by businesses to measure the cost of production of goods against the expectations reflected in the budget. It compares the actual overhead costs per unit that were achieved to the expected or budgeted cost per item.

Fixed overhead volume variance is favorable when the applied fixed overhead cost exceeds the budgeted amount. This is because the units produced in such a case are more than the quantity expected from current production capacity and this reflects efficient use of fixed resources. If actual production is greater than budgeted production, the production volume variance is favorable. That is, the total fixed overhead has been allocated to a greater number of units, resulting in a lower production cost per unit. The total variable overhead cost variance is also found by combining the variable overhead rate variance and the variable overhead efficiency variance.

Causes of Overhead Variance

To determine how much of the -$6.7M is related to volume, we apply the calculation described above to each product type as shown in the chart below (Illustration B.2). As the chart below shows, of the total -$6.7M COGS variance, the total volume impact is -$3.8M. During any financial review, variances against plan are always items of intense discussion and require in-depth analysis.

It is likely that the amounts determined for standard overhead costs will differ from what actually occurs. Production volume variance is the difference between your budgeted overhead and actual overhead. Using these calculations can help make sure you’re net realizable value formula producing enough units to run at a profit. You can have a more efficient production process while keeping a steady production level. Budget or spending variance is the difference between the budget and the actual cost for the actual hours of operation.

4 Compute and Evaluate Overhead Variances

This means that the actual production volume was less than the planned volume, resulting in a higher cost per unit than planned because the fixed overhead costs were spread over fewer units. The production volume variance measures the amount of overhead applied to the number of units produced. It is the difference between the actual number of units produced in a period and the budgeted number of units that should have been produced, multiplied by the budgeted overhead rate. The hourly rate in this formula includes such indirect labor costs as shop foreman and security. If actual labor hours are less than the budgeted or standard amount, the variable overhead efficiency variance is favorable; if actual labor hours are more than the budgeted or standard amount, the variance is unfavorable. Assume that a manufacturer had budgeted $300,000 of fixed manufacturing overhead (supervisors’ compensation, depreciation, etc.) for the upcoming year.

COGS Variance Component 2: Mix Variance Analysis

To determine the overhead standard cost, companies prepare a flexible budget that gives estimated revenues and costs at varying levels of production. The standard overhead cost is usually expressed as the sum of its component parts, fixed and variable costs per unit. Note that at different levels of production, total fixed costs are the same, so the standard fixed cost per unit will change for each production level. However, the variable standard cost per unit is the same per unit for each level of production, but the total variable costs will change.

Analysis

Factory rent, equipment purchases, and insurance costs all fall into this category. Management salaries do not usually vary with incremental changes in production. This creates a situation where businesses might think that producing more is always better because it results in lower overhead costs per unit. A favorable volume variance occurs when a business is able to produce more units of a product than the anticipated amount. This results in a lower overhead cost per unit, and ultimately, a lower production cost per unit. This is said to be a favorable variance because the total fixed overhead is being allocated to a greater number of units.

It is the normal capacity that the company or the existing facility can achieve for the period. This figure is usually included in the budget of production that is planned or scheduled before the production starts. As per our calculation, there is an unfavorable production volume variance of $6,000. The graph below (Illustration D.1) also represents the variance impacts of volume, mix and rate by demonstrating a “variance walk” from plan to actual.
