Variance Analysis for Material and Labour
In budgeting and financial management, variance refers to the difference between actual results and the budgeted or expected results. It is a measure of how well an organization has performed compared to its planned or expected performance. Variance analysis is the process of examining and analyzing the variances to identify the reasons for the differences between actual results and budgeted or expected results.
There are different types of variances that can be analyzed:
- Revenue variances: These are variances between actual revenue and budgeted or expected revenue.
- Cost variances: These are variances between actual costs and budgeted or expected costs.
- Volume variances: These are variances that result from differences in the volume of goods or services produced or sold compared to what was budgeted or expected.
- Efficiency variances: These are variances that result from differences in the efficiency of production or operations compared to what was budgeted or expected.
Variance analysis involves identifying the reasons for the variances, such as changes in market conditions, unexpected expenses, or changes in production or operations. By understanding the reasons for the variances, organizations can take corrective actions to address any issues and improve their future performance.
Material Variances
Material variances are a type of variance analysis that focuses on the differences between actual and expected material costs. Material variances can be divided into two main categories: price variances and usage variances.
Price variances relate to the difference between the actual cost of materials used and the expected cost of materials, based on the budgeted or standard price. Usage variances relate to the difference between the actual amount of materials used and the expected amount, based on the budgeted or standard usage.
The formula for calculating material variances is:
Material Variances = (Actual Quantity x Actual Price) – (Standard Quantity x Standard Price)
This formula can be further broken down into price variance and usage variance components:
Price Variance = (Actual Quantity x Actual Price) – (Actual Quantity x Standard Price)
Usage Variance = (Actual Quantity x Standard Price) – (Standard Quantity x Standard Price)
The components of material variances are:
- Actual Quantity: The actual quantity of materials used in production or operations.
- Standard Quantity: The expected or budgeted quantity of materials needed for production or operations, based on the standard usage rate.
- Actual Price: The actual cost per unit of material purchased or used.
- Standard Price: The expected or budgeted cost per unit of material, based on the standard price.
The function of material variances is to identify the reasons for the differences between actual and expected material costs, and to help management make better decisions about resource allocation. By analyzing material variances, management can identify areas where costs can be reduced or where there may be issues with quality or waste.
Labour Variances
Labour variances are a type of variance analysis that focuses on the differences between actual and expected labour costs. Labour variances can be divided into two main categories: rate variances and efficiency variances.
Rate variances relate to the difference between the actual cost of labour used and the expected cost of labour, based on the budgeted or standard rate. Efficiency variances relate to the difference between the actual amount of labour used and the expected amount, based on the budgeted or standard hours.
The formula for calculating labour variances is:
Labour Variances = (Actual Hours x Actual Rate) – (Standard Hours x Standard Rate)
This formula can be further broken down into rate variance and efficiency variance components:
Rate Variance = (Actual Hours x Actual Rate) – (Actual Hours x Standard Rate)
Efficiency Variance = (Actual Hours x Standard Rate) – (Standard Hours x Standard Rate)
The components of labour variances are:
- Actual Hours: The actual number of hours worked by employees.
- Standard Hours: The expected or budgeted number of hours needed for production or operations, based on the standard time for each task.
- Actual Rate: The actual cost per hour for labour.
- Standard Rate: The expected or budgeted cost per hour for labour, based on the standard rate for each job.
The function of labour variances is to identify the reasons for the differences between actual and expected labour costs, and to help management make better decisions about resource allocation. By analyzing labour variances, management can identify areas where costs can be reduced or where there may be issues with productivity or efficiency.
Overheads Variances
Overhead variances are a type of variance analysis that focuses on the differences between actual and expected overhead costs. Overhead variances can be divided into two main categories: spending variances and efficiency variances.
Spending variances relate to the difference between the actual overhead cost incurred and the expected overhead cost, based on the budgeted or standard overhead rate. Efficiency variances relate to the difference between the actual amount of overheads used and the expected amount, based on the budgeted or standard hours.
The formula for calculating overhead variances is:
Overhead Variances = Actual Overhead – (Standard Overhead Rate x Standard Hours)
This formula can be further broken down into spending variance and efficiency variance components:
Spending Variance = Actual Overhead – (Actual Hours x Standard Overhead Rate)
Efficiency Variance = (Actual Hours x Standard Overhead Rate) – (Standard Hours x Standard Overhead Rate)
The components of overhead variances are:
- Actual Overhead: The actual overhead cost incurred by the organization.
- Standard Overhead Rate: The expected or budgeted overhead cost per unit, based on the standard rate for each activity or product.
- Actual Hours: The actual number of hours worked by employees.
- Standard Hours: The expected or budgeted number of hours needed for production or operations, based on the standard time for each task.
The function of overhead variances is to identify the reasons for the differences between actual and expected overhead costs, and to help management make better decisions about resource allocation. By analyzing overhead variances, management can identify areas where costs can be reduced or where there may be issues with productivity or efficiency.
Sales Variances
Sales variances are a type of variance analysis that focuses on the differences between actual sales and expected sales. Sales variances can be divided into two main categories: price variances and volume variances.
Price variances relate to the difference between the actual selling price per unit and the budgeted or standard selling price per unit. Volume variances relate to the difference between the actual number of units sold and the budgeted or standard number of units sold.
The formula for calculating sales variances is:
Sales Variances = Actual Sales – (Standard Selling Price x Standard Volume)
This formula can be further broken down into price variance and volume variance components:
Price Variance = Actual Sales – (Actual Volume x Standard Selling Price)
Volume Variance = (Actual Volume x Standard Selling Price) – (Standard Volume x Standard Selling Price)
The components of sales variances are:
- Actual Sales: The actual revenue generated by the organization from sales.
- Standard Selling Price: The expected or budgeted selling price per unit, based on the standard rate for each product.
- Actual Volume: The actual number of units sold by the organization.
- Standard Volume: The expected or budgeted number of units sold, based on the standard rate for each product.
The function of sales variances is to identify the reasons for the differences between actual and expected sales, and to help management make better decisions about pricing and sales strategy. By analyzing sales variances, management can identify areas where revenue can be increased or where there may be issues with sales volume or pricing.
Advantages of variance analysis:
- Identifying areas for improvement:
Variance analysis can help identify areas where actual performance is deviating from expected performance. By identifying these areas, management can focus their attention and resources on improving performance in those areas.
- Providing feedback to employees:
Variance analysis can provide employees with feedback on their performance. This can be motivational for employees who are performing well, and can also help identify areas where employees may need additional training or support.
- Facilitating decision making:
Variance analysis can help management make informed decisions about resource allocation and other strategic decisions. By understanding the causes of variances, management can make better decisions about where to allocate resources to improve performance.
- Supporting budgetary control:
Variance analysis can help management monitor and control costs by identifying areas where costs are exceeding expectations. This can help ensure that the organization stays within its budget.
Disadvantages of Variance analysis:
- Time consuming:
Variance analysis can be time consuming, particularly if the organization has a large number of variances to analyze. This can be a burden on staff and may delay decision making.
- Limited information:
Variance analysis only provides information about the difference between actual and expected results. It does not provide information about why those differences occurred, or about other factors that may be affecting performance.
- Overemphasis on short-term performance:
Variance analysis is often focused on short-term performance. This can lead to a focus on achieving short-term goals at the expense of longer-term strategic objectives.
- Reliance on assumptions:
Variance analysis relies on assumptions about what constitutes expected performance. If those assumptions are incorrect, the analysis may not be useful.
