Variance analysis is a financial assessment tool used to evaluate the differences between planned and actual figures. It compares actual costs against projected costs for materials, labor, and overheads, identifying areas of overperformance or underperformance. This analysis facilitates better cost control and financial management. The accounting treatment of variances involves adjusting the cost of goods sold (COGS) and, in some cases, inventory costs.
Types of Variances
Material Variances
Material variances represent the deviations between actual material costs and standard or budgeted costs.
- Material Price Variance: This variance reflects the difference between the standard price of materials and the actual price paid. It is a key indicator for cost management in manufacturing and procurement.
- Material Usage Variance: Also known as material quantity variance, this measures the difference between the actual quantity of materials used in production and the standard quantity expected for actual output, valued at the standard price.
Labor Variances
Labor variances assess the difference between actual and budgeted labor costs, aiding businesses in identifying inefficiencies and optimizing cost control.
- Labor Rate Variance: This represents the difference between actual labor costs and standard (budgeted) labor costs due to variations in hourly wage rates. It is calculated as:
- Labor Efficiency Variance (LEV): LEV measures the difference between actual labor hours used and standard hours expected for a given output. This variance serves as an indicator of labor productivity.
Calculation:
- Subtract standard hours from actual hours
- Multiply the result by the standard rate
Interpretation:
- A negative LEV suggests reduced labor productivity
- A positive LEV indicates improved labor productivity
Potential Causes:
- Employee absenteeism or paid time off
- Overtime hours
- Use of temporary workers at different wage rates
- Technology malfunctions affecting efficiency
- Poor working conditions
- Production delays due to material, tool, or instruction shortages
Overhead Variances
Overhead variances analyze the difference between actual and budgeted overhead costs, helping assess cost control and resource management.
Fixed Overhead Variances
- Fixed Overhead Spending Variance: The difference between actual fixed overhead costs and budgeted fixed overhead costs.
- Fixed Overhead Volume Variance: The variance between budgeted fixed overhead costs and the fixed overhead costs absorbed based on actual production levels.
Variable Overhead Variances
- Variable Overhead Spending Variance: The difference between actual variable overhead costs and the expected variable overhead costs based on production levels.
- Variable Overhead Efficiency Variance: The difference between actual and standard production levels, multiplied by the standard variable overhead rate.
Key Formulas
- Fixed Overhead Spending Variance:
- Fixed Overhead Volume Variance:
- Variable Overhead Spending Variance:
- Variable Overhead Efficiency Variance:
Favorable vs. Unfavorable Variances
- A favorable variance occurs when actual results (e.g., lower costs or higher revenue) surpass expectations.
- An unfavorable variance arises when actual results are worse than anticipated.
Steps in Variance Analysis
- Calculate the difference: Compare actual costs with standard/budgeted costs.
- Investigate causes: Determine the reasons for variances.
- Report findings: Communicate insights to management.
- Implement corrective actions: Develop strategies to address variances.
Accounting Treatment of Variances
Cost of Goods Sold (COGS)
Variances can be allocated to COGS either through a single variance account or by adjusting the costs of materials, labor, and overheads used in production.
Inventory
When variances are significant and inventory levels are high, variances may also be allocated to inventory.
Methods of Accounting for Variances
- Proportionate Allocation: Distribute variances between COGS and inventory based on their respective proportions of total costs.
- Direct Allocation: Assign variances directly to either COGS or inventory, depending on the nature of the variance.
- Write-Off: Minor variances may be written off directly to the income statement.
By employing variance analysis and accounting for variances appropriately, businesses can enhance financial performance, improve cost control, and optimize resource allocation.
