In the realm of cost accounting, understanding overhead variance is crucial for businesses to optimize their production processes, reduce costs, and enhance profitability. Overhead variance analysis helps companies identify the differences between actual and standard overhead costs, enabling them to make informed decisions about resource allocation and process improvements. In this article, we will delve into the world of overhead variance analysis, focusing on the calculation of fixed and variable overhead variance.
Understanding Overhead Variance
Overhead variance occurs when there is a difference between the actual overhead costs incurred by a company and the standard overhead costs that were budgeted or planned. This variance can be attributed to various factors, such as changes in production volume, inefficiencies in the production process, or fluctuations in overhead costs.
There are two types of overhead variance: fixed overhead variance and variable overhead variance. Fixed overhead variance occurs when there is a difference between the actual and standard fixed overhead costs, while variable overhead variance occurs when there is a difference between the actual and standard variable overhead costs.
Calculating Fixed Overhead Variance
Fixed overhead variance is calculated by comparing the actual fixed overhead costs with the standard fixed overhead costs. The formula for calculating fixed overhead variance is:
Fixed Overhead Variance = Actual Fixed Overhead Costs – Standard Fixed Overhead Costs
Step-by-Step Calculation of Fixed Overhead Variance
To calculate fixed overhead variance, follow these steps:
- Determine the actual fixed overhead costs incurred by the company during a specific period.
- Determine the standard fixed overhead costs that were budgeted or planned for the same period.
- Calculate the fixed overhead variance by subtracting the standard fixed overhead costs from the actual fixed overhead costs.
Example of Fixed Overhead Variance Calculation
Suppose a company incurred actual fixed overhead costs of $100,000 during a quarter, while the standard fixed overhead costs were $90,000. To calculate the fixed overhead variance, we would subtract the standard fixed overhead costs from the actual fixed overhead costs:
Fixed Overhead Variance = $100,000 – $90,000 = $10,000
In this example, the company has a fixed overhead variance of $10,000, indicating that the actual fixed overhead costs were higher than the standard fixed overhead costs.
Calculating Variable Overhead Variance
Variable overhead variance is calculated by comparing the actual variable overhead costs with the standard variable overhead costs. The formula for calculating variable overhead variance is:
Variable Overhead Variance = Actual Variable Overhead Costs – Standard Variable Overhead Costs
Step-by-Step Calculation of Variable Overhead Variance
To calculate variable overhead variance, follow these steps:
- Determine the actual variable overhead costs incurred by the company during a specific period.
- Determine the standard variable overhead costs that were budgeted or planned for the same period.
- Calculate the variable overhead variance by subtracting the standard variable overhead costs from the actual variable overhead costs.
Example of Variable Overhead Variance Calculation
Suppose a company incurred actual variable overhead costs of $50,000 during a quarter, while the standard variable overhead costs were $45,000. To calculate the variable overhead variance, we would subtract the standard variable overhead costs from the actual variable overhead costs:
Variable Overhead Variance = $50,000 – $45,000 = $5,000
In this example, the company has a variable overhead variance of $5,000, indicating that the actual variable overhead costs were higher than the standard variable overhead costs.
Interpreting Overhead Variance
Once the fixed and variable overhead variance have been calculated, it is essential to interpret the results to understand the underlying causes of the variance. A positive variance indicates that the actual overhead costs were higher than the standard overhead costs, while a negative variance indicates that the actual overhead costs were lower than the standard overhead costs.
Causes of Overhead Variance
There are several causes of overhead variance, including:
- Changes in production volume
- Inefficiencies in the production process
- Fluctuations in overhead costs
- Changes in the cost structure of the company
Example of Interpreting Overhead Variance
Suppose a company has a fixed overhead variance of $10,000 and a variable overhead variance of $5,000. To interpret these results, we would need to analyze the underlying causes of the variance. For example, the fixed overhead variance may be due to an increase in depreciation costs, while the variable overhead variance may be due to an increase in the cost of raw materials.

What is Overhead Variance Analysis and Why is it Important?
Overhead variance analysis is a method used in cost accounting to analyze and understand the differences between actual and standard overhead costs. It is essential for businesses to identify areas where costs are deviating from expectations, allowing them to make informed decisions to optimize their operations and improve profitability. By analyzing overhead variances, companies can pinpoint the root causes of cost discrepancies and take corrective actions to minimize waste and maximize efficiency.
Overhead variance analysis is particularly important in industries with high overhead costs, such as manufacturing, construction, and healthcare. By accurately identifying and addressing overhead variances, businesses can reduce costs, enhance productivity, and gain a competitive edge in their respective markets. Moreover, overhead variance analysis can help companies to better allocate resources, set realistic budgets, and make more accurate financial projections.
What are the Different Types of Overhead Variances?
There are two primary types of overhead variances: fixed overhead variance and variable overhead variance. Fixed overhead variance occurs when the actual fixed overhead costs differ from the standard fixed overhead costs. This type of variance is typically caused by changes in the volume of production, changes in the cost of fixed overhead items, or errors in estimating fixed overhead costs. Variable overhead variance, on the other hand, occurs when the actual variable overhead costs differ from the standard variable overhead costs.
Variable overhead variance can be further broken down into two sub-components: variable overhead spending variance and variable overhead efficiency variance. Variable overhead spending variance occurs when the actual cost of variable overhead items differs from the standard cost, while variable overhead efficiency variance occurs when the actual quantity of variable overhead items used differs from the standard quantity. Understanding these different types of overhead variances is crucial for accurate analysis and effective cost management.
How is Fixed Overhead Variance Calculated?
Fixed overhead variance is calculated by subtracting the standard fixed overhead costs from the actual fixed overhead costs. The formula for calculating fixed overhead variance is: Fixed Overhead Variance = Actual Fixed Overhead Costs – Standard Fixed Overhead Costs. This calculation can be further broken down into two components: fixed overhead budget variance and fixed overhead volume variance. Fixed overhead budget variance occurs when the actual fixed overhead costs differ from the budgeted fixed overhead costs, while fixed overhead volume variance occurs when the actual production volume differs from the standard production volume.
To calculate fixed overhead variance, companies need to have accurate records of their actual and standard fixed overhead costs, as well as their actual and standard production volumes. By analyzing fixed overhead variance, companies can identify areas where costs are deviating from expectations and take corrective actions to minimize waste and maximize efficiency. Fixed overhead variance analysis can also help companies to better allocate resources, set realistic budgets, and make more accurate financial projections.
What is the Formula for Calculating Variable Overhead Variance?
The formula for calculating variable overhead variance is: Variable Overhead Variance = (Actual Variable Overhead Costs – Standard Variable Overhead Costs) / Standard Variable Overhead Rate. This formula takes into account the actual variable overhead costs, standard variable overhead costs, and standard variable overhead rate. The standard variable overhead rate is calculated by dividing the standard variable overhead costs by the standard quantity of variable overhead items.
Variable overhead variance can be further broken down into two sub-components: variable overhead spending variance and variable overhead efficiency variance. Variable overhead spending variance is calculated by subtracting the standard variable overhead costs from the actual variable overhead costs, while variable overhead efficiency variance is calculated by subtracting the standard quantity of variable overhead items from the actual quantity of variable overhead items. By analyzing variable overhead variance, companies can identify areas where costs are deviating from expectations and take corrective actions to minimize waste and maximize efficiency.
What are the Common Causes of Overhead Variances?
There are several common causes of overhead variances, including changes in production volume, changes in the cost of overhead items, errors in estimating overhead costs, and inefficiencies in the production process. Changes in production volume can cause fixed overhead variance, as the actual fixed overhead costs may differ from the standard fixed overhead costs. Changes in the cost of overhead items can cause variable overhead variance, as the actual cost of variable overhead items may differ from the standard cost.
Errors in estimating overhead costs can also cause overhead variances, as the actual overhead costs may differ from the estimated costs. Inefficiencies in the production process can also cause overhead variances, as the actual quantity of overhead items used may differ from the standard quantity. By identifying the root causes of overhead variances, companies can take corrective actions to minimize waste and maximize efficiency. This can involve adjusting production volumes, renegotiating contracts with suppliers, or implementing process improvements.
How Can Overhead Variance Analysis be Used to Improve Business Performance?
Overhead variance analysis can be used to improve business performance by identifying areas where costs are deviating from expectations and taking corrective actions to minimize waste and maximize efficiency. By analyzing overhead variances, companies can pinpoint the root causes of cost discrepancies and take targeted actions to address these issues. This can involve adjusting production volumes, renegotiating contracts with suppliers, or implementing process improvements.
Overhead variance analysis can also be used to set realistic budgets and make more accurate financial projections. By understanding the causes of overhead variances, companies can develop more accurate forecasts of future costs and revenues, allowing them to make more informed decisions about investments and resource allocation. Moreover, overhead variance analysis can help companies to identify opportunities for cost savings and process improvements, allowing them to gain a competitive edge in their respective markets.
What are the Best Practices for Implementing Overhead Variance Analysis?
The best practices for implementing overhead variance analysis include establishing clear goals and objectives, defining key performance indicators, and developing a comprehensive variance analysis framework. Companies should also ensure that they have accurate and reliable data, as well as a robust system for tracking and analyzing overhead costs. Regular review and analysis of overhead variances is also essential, as this allows companies to identify areas for improvement and take corrective actions.
Companies should also consider implementing a continuous improvement culture, where employees are encouraged to identify areas for improvement and suggest solutions. This can involve providing training and development opportunities, as well as recognizing and rewarding employees who contribute to cost savings and process improvements. By following these best practices, companies can ensure that their overhead variance analysis is effective and sustainable, leading to long-term improvements in business performance.
