Standard costing is a crucial technique in management accounting that pre-establishes costs for materials, labor, and overhead. These predetermined costs, known as standards, serve as benchmarks against which actual costs are compared. Introduced as a refinement of historical costing, standard costing gained prominence in the 20th century with the rise of scientific management principles. It’s not merely about setting targets; it’s a proactive approach to cost control, performance evaluation, and decision-making, enabling organizations to identify inefficiencies and take corrective actions. The effective use of standard costing relies heavily on accurate variance analysis, distinguishing between factors within management’s control and those stemming from external influences.
What is Standard Costing?
Standard costing is a system where pre-determined costs (standards) are established for each element of cost – direct materials, direct labor, and overheads – for a specific level of production. These standards represent the ‘should cost’ and are based on engineering studies, work measurement, and past experience. It differs from historical costing, which records actual costs after they are incurred. The standards are used as a basis for comparing actual costs and identifying variances.
How is it Used in Management Accounting?
Standard costing plays a vital role in several management accounting functions:
- Cost Control: By comparing actual costs to standards, variances are identified, highlighting areas where costs deviate from expectations.
- Performance Evaluation: Variances can be used to assess the performance of departments, managers, and employees.
- Inventory Valuation: Standards can be used to value inventory, providing a more consistent and accurate valuation.
- Budgeting and Forecasting: Standards form the basis for preparing budgets and forecasts.
- Decision Making: Standard costs aid in pricing decisions, make-or-buy decisions, and product mix decisions.
Differentiating Between Controllable and Uncontrollable Variances
Variance analysis is the cornerstone of standard costing. Variances are the differences between standard costs and actual costs. These variances can be categorized as controllable and uncontrollable.
Controllable Variances
Controllable variances are those that can be influenced by management within a specific period. These variances typically relate to:
- Material Usage Variance: Arises from the difference between the standard quantity of materials allowed for actual production and the actual quantity used. (e.g., inefficient material handling, poor workmanship).
- Labor Efficiency Variance: Results from the difference between the standard hours allowed for actual production and the actual hours worked. (e.g., inadequate training, poor supervision).
- Variable Overhead Efficiency Variance: Arises from the difference between the standard hours allowed for actual production and the actual hours worked, applied to the variable overhead rate.
- Spending Variances (Material & Labor): Differences between standard price/rate and actual price/rate, when the quantity used is within control.
Uncontrollable Variances
Uncontrollable variances are those that are beyond the direct control of management in the short run. These variances typically relate to:
- Material Price Variance: Arises from the difference between the standard price of materials and the actual price paid. (e.g., fluctuations in market prices, supplier price increases).
- Labor Rate Variance: Results from the difference between the standard labor rate and the actual labor rate paid. (e.g., changes in wage rates due to union agreements, labor market conditions).
- Fixed Overhead Variance: Variances related to fixed overhead costs are often considered less controllable in the short run, as these costs are typically committed.
Strategic Actions Based on Variance Distinction
The distinction between controllable and uncontrollable variances dictates the strategic actions taken:
| Variance Type | Strategic Action |
|---|---|
| Controllable Variance (Adverse) | Investigate the root cause (e.g., training, process improvement, quality control). Implement corrective actions to improve efficiency and reduce waste. Hold responsible managers accountable. |
| Controllable Variance (Favorable) | Analyze the reasons for the favorable variance. Identify best practices and replicate them in other areas. Reward responsible managers. |
| Uncontrollable Variance (Adverse) | Focus on mitigating the impact of the variance. Negotiate with suppliers, explore alternative materials, or adjust pricing strategies. Long-term strategies might involve hedging or vertical integration. |
| Uncontrollable Variance (Favorable) | While favorable, analyze the reason. It might be a temporary market condition. Avoid relying on it for future planning. |
For example, a large adverse material price variance due to a sudden increase in raw material costs (uncontrollable) might prompt a company to explore long-term supply contracts or consider alternative materials. Conversely, a significant adverse labor efficiency variance (controllable) would necessitate an investigation into training programs and work processes.
Conclusion
Standard costing remains a powerful tool for management accounting, providing a framework for cost control, performance evaluation, and informed decision-making. The key to its success lies in accurately establishing standards and diligently analyzing variances. Crucially, differentiating between controllable and uncontrollable variances allows management to focus resources on areas where they can have the greatest impact, leading to improved efficiency, profitability, and strategic advantage. Continuous monitoring and refinement of standards are essential to maintain their relevance in a dynamic business environment.
