STANDARD COSTING: COMPLETE GUIDE TO SETTING STANDARDS, VARIANCE ANALYSIS, AND PERFORMANCE MANAGEMENT
Cost control remains essential for business survival and profitability. Yet many organizations struggle to understand why their costs deviate from expectations and how to take corrective action. Standard costing provides the solution—a powerful management accounting tool that establishes cost targets, measures performance, and drives continuous improvement.
Standard costing establishes predetermined estimates of product or service costs—known as standard costs—and then compares these estimates with actual costs to identify variances. By analyzing these variances, management can pinpoint inefficiencies, take corrective action, and improve overall performance.
This comprehensive guide covers everything you need to know about standard costing: what it is, how to set standards, how to calculate and analyze variances, and how to use this information for effective performance management.
What Is Standard Costing?
Standard costing is a management accounting technique that establishes predetermined costs for products or services and then compares actual costs against these predetermined standards. The system operates on several key principles:
-
Setting standards: Management establishes target costs for each production component based on historical data, engineering studies, and market conditions.
-
Recording at standard: Production processes record inventory and cost of goods sold using predetermined standard costs, not actual costs.
-
Tracking variances: The differences between standard and actual costs (called variances) are calculated and analyzed to identify inefficiencies or cost savings.
-
Taking action: Management uses variance analysis to make informed decisions about pricing, production methods, and purchasing strategies.
This system creates a continuous improvement cycle where standards are periodically reviewed and updated based on actual performance, helping businesses progressively optimize their operations and costs.
The Pain Points: Why Businesses Struggle with Standard Costing
Many Nigerian and global businesses face significant challenges when implementing standard costing systems. Research by the Chartered Institute of Management Accountants (CIMA) reveals that although most manufacturing companies do use standard costing, they tend to be very selective in their use of variance analysis.
Common Pain Points Include:
Outdated Standards: Modern business environments change rapidly, and standards quickly become outdated, losing their control and motivational effects. When a standard is incorrect or outdated, any comparison with actual results becomes misleading.
Complexity and Cost: Standard costing and variance reporting can be time-consuming and expensive to operate.
Lack of Manager Understanding: Elaborate and complex variances, especially overhead variances, are often poorly understood by managers and prove ineffective for control purposes.
JIT Incompatibility: Standard costing principles—that a standard set before a period remains a satisfactory measure throughout the period, and that performance is acceptable if it meets this standard—conflict with JIT manufacturing’s continuous improvement philosophy and drive to zero wastage.
Data Quality Issues: Poor counts, mis-scans, lagging purchase price updates, or unposted rework can make otherwise sound standards appear wrong.
The Variance Interpretation Challenge: Actual results may differ from standard for several reasons, including errors in measuring actual outcomes, outdated standards, efficient or inefficient operations, and random uncontrollable factors.
Types of Standards
When setting standards, organizations must decide what level of efficiency to assume. The standard set becomes a performance target, and perceived unattainability may negatively impact staff motivation. Similarly, standards too easily attained provide no incentive for improvement.
1. Ideal Standards
Ideal standards assume perfect operating conditions. No allowance is made for wastage, labour inefficiency, or machine breakdowns. The ideal standard cost represents what would be achievable under perfect conditions. In practice, organizations rarely achieve ideal standards.
Best for: Long-term targets and providing senior managers with an indication of potential savings. However, they are unlikely to motivate employees as they appear unachievable.
2. Attainable Standards
Attainable standards assume efficient but not perfect operating conditions. Allowance is made for waste and inefficiency. However, the attainable standard is set at a higher efficiency level than current performance, requiring some improvements to achieve the standard level of performance.
Best for: Most standard costing systems as they provide a realistic yet challenging target that motivates employees.
3. Current Standards
Current standards are based on current working conditions and what the entity can achieve at the moment. They do not provide any incentive for significant performance improvements and may be considered unsatisfactory when current operating performance is inefficient.
Best for: Situations where immediate cost control is needed rather than performance improvement.
4. Basic Standards
Basic standards remain unchanged over a long period. Variances are calculated by comparing actual results with the basic standard, and gradual performance improvements appear in an improving trend in reported variances.
Best for: Tracking long-term performance trends over several years.
Setting Standards: A Step-by-Step Process
1. Setting Direct Material Standards
For direct materials, two key variables must be established:
Standard quantity: The predetermined amount of materials needed to produce one unit
Standard price: The expected cost per unit of material
Example: A furniture manufacturer sets standards of 10 board feet of oak at $5 per board foot for a chair.
2. Setting Direct Labor Standards
Direct labor standards include:
Standard hours: The predetermined time required to complete one unit
Standard rate: The expected hourly wage rate
Example: A winery establishes standard labor costs where each case of wine should require 0.5 hours of direct labor at a standard rate of $20 per hour.
3. Setting Overhead Standards
Manufacturing overhead encompasses all indirect production costs that cannot be directly traced to specific products. Overhead is typically divided into:
Variable overhead: Costs that change with production volume (utilities, supplies)
Fixed overhead: Costs that remain constant regardless of production level (rent, depreciation)
Standard overhead costs are typically applied using predetermined rates based on a cost driver like direct labor hours or machine hours.
When to Update Standard Costs
Most companies undergo a cost updating process once a year to bring standard costs closer to actual costs. However, when actual costs fluctuate considerably over time, resulting in large positive or negative variances, organizations can either update costs more frequently or respond to triggering events.
Update Frequency Options:
-
Increased frequency option: Schedule a complete cost review semi-annually or quarterly. Best practice recommends conducting this periodic review only when cost variances exceed a certain threshold (e.g., 5% jump).
-
Selective increased frequency option: Select certain commodity types for an increased review schedule (e.g., using the Pareto principle to update costs for the 20% of items that make up 80% of total costs).
-
Review when trigger activated option: Trigger a cost review whenever a specific item experiences a cost variance of at least 5% for several consecutive months.
Example Triggers for Standard Cost Updates:
Material costs change by 20% due to supply chain disruptions
Labor costs change due to a new union agreement increasing hourly wage rates by 15%
Production process improvement through automation reducing labor hours and altering overhead allocation
Variance Analysis: Understanding the Components
Variance analysis compares actual costs to standard costs and investigates the differences. Each day, accounting prepares reports showing whether budgeted costs were exceeded and which cost elements (material, labor, overhead) caused the variance.
1. Direct Material Variances
Direct material variances measure the difference between the actual and standard costs of materials used in production.
Material Price Variance – Tells how much more than budgeted (standard) price was paid for the material used or bought.
Formula: (Actual Price – Standard Price) × Actual Quantity
Example: Standard material price is $10 per kg, actual price is $10.50 per kg for 2,200 kg purchased: (10.50 – 10.00) × 2,200 = $1,100 Unfavorable.
Material Usage (Quantity) Variance – Tells whether the quantity of material used exceeds what should have been used according to the standard.
Formula: (Actual Quantity – Standard Quantity) × Standard Price
Example: Standard usage is 2,000 kg, actual usage is 2,100 kg at $10 per kg: (2,100 – 2,000) × 10 = $1,000 Unfavorable.
2. Direct Labor Variances
Labor variances include:
Labor Rate (Price) Variance – Tells how much more or less was paid to workers per hour than the standard set.
Formula: (Actual Rate – Standard Rate) × Actual Hours
Example: Standard rate is $20/hour, actual rate is $21/hour for 5,200 hours: ($21 – $20) × 5,200 = $5,200 Unfavorable.
Labor Efficiency Variance – Tells the difference between the hours expended and paid for compared to what should have been used if the standard was met.
Formula: (Actual Hours – Standard Hours) × Standard Rate
Example: Standard hours are 5,000, actual hours are 5,200 at $20/hour: (5,200 – 5,000) × $20 = $4,000 Unfavorable.
3. Overhead Variances
Overhead variances are more complex and may include:
Variable Overhead Spending Variance – Difference between actual variable overhead cost and budgeted variable overhead based on actual hours worked.
Variable Overhead Efficiency Variance – Measures how efficiently the cost driver (like labor hours) was used.
Fixed Overhead Spending (Budget) Variance – Difference between actual fixed overhead cost and budgeted fixed overhead.
Fixed Overhead Production Volume Variance – Occurs when actual production differs from the planned level used to set fixed overhead rates.
Example of Fixed Overhead Variance Calculation:
Budgeted fixed overhead: $60,000
Actual fixed overhead: $62,000
Standard direct labor hours allowed for actual production: 6,000
Standard fixed overhead rate: $8 per DLH
Fixed OH Spending Variance: $62,000 – $60,000 = $2,000 Unfavorable
Fixed OH Volume Variance: $60,000 – (6,000 × $8) = $12,000 Unfavorable
Planning and Operational Variances
An important distinction in variance analysis separates planning variances from operational variances.
Operational Variances: Variances that occur due to factors almost or entirely within management’s control. These are calculated using revised (ex post) standards.
Planning Variances: Variances that occur from changes in factors external to the business. As planning variances are not under operational management’s control, management cannot be held accountable for them.
Why This Distinction Matters
Traditional variance analysis often fails to distinguish between factors within management’s control and external factors. When standards become unrealistic due to changes in market conditions, technology, or other external factors, traditional variance analysis may indicate poor performance when it is not the manager’s fault.
Example of Planning and Operational Variances:
Greenco Nigeria Limited manufactures Product G, with a standard direct material cost per unit of 5 kilos at N6 per kilo = N30. Actual output during a month is 4,000 units, and materials actually used were 16,500 kilos at a cost of N119,000.
Investigation shows that the original standard was unrealistic and should have been 4 kilos at N7 per kilo = N28 per unit.
Analysis:
Usage Operational Variance: (16,500 – 16,000) × N7 = N3,500 Adverse
Price Operational Variance: (N7 – Actual Price) × 16,500 = N3,500 Adverse
Planning Variance: (20,000 × N6) – (16,000 × N7) = N8,000 Favorable
Calculating Traditional vs. Operational Variances
Traditional Variances use the original (ex-ante) standard, while Operational Variances use the revised (ex-post) standard.
| Variance Type | Standard Used | Who is Accountable |
|---|---|---|
| Traditional | Original Standard | Difficult to assign |
| Operational | Revised Standard | Operational Management |
| Planning | Difference between original and revised | Senior Management/External Factors |
Variance Relationships: Understanding the Interconnections
Variances do not exist in isolation—they often influence each other. Effective standard costing requires analyzing these relationships to understand the true causes of cost deviations.
Common Interrelationships:
Material Price and Usage Trade-off: Purchasing lower-quality materials (favorable price variance) might lead to more waste (unfavorable usage variance) or more labor hours (unfavorable labor efficiency variance).
Labor Rate and Efficiency Trade-off: Paying higher wages (unfavorable rate variance) might lead to faster production (favorable efficiency variance).
Volume and Efficiency: When production volume differs from the planned level used to set fixed overhead rates, a volume variance arises that is not truly controllable by operational management.
Standard Costing as a Performance Management Tool
Management by Exception
Variance analysis facilitates action through “management by exception.” Managers concentrate on business areas performing below or above expectations while largely ignoring those conforming to expectations.
Key Principles:
Large adverse variances indicate poor performance and the need for management control action.
Large favorable variances indicate unexpected good performance. Management might consider how to maintain this good performance in the future.
Performance Reporting
Variance reports are produced at the end of each control period (e.g., at the end of each month). Variances might be reported in a statement for the accounting period that reconciles budgeted profit with actual profit. This statement is known as an operating statement.
Motivational Impact
A properly developed and understood standard costing system with full participation and involvement creates a positive attitude towards cost control throughout the organization. Standard setting, revision, and monitoring encourage reappraisal of methods, materials, and techniques, leading to cost reductions and process improvement.
Benefits According to Nigerian Research
Research conducted on standard costing in Nigerian manufacturing firms (including Nigerian Bottling Company, Coca-Cola, and Seven Up) established that:
Standard costing technique fosters management effectiveness and corporate profits
Standard costing supports performance evaluation
Standard costing enables cost control and inventory control
Standard costing provides motivation, encouragement, and ensures efficiency
Standard costing reduces inefficiency in activities
Common Drawbacks and Limitations
Despite its benefits, standard costing has several limitations:
1. Conflict with Continuous Improvement: Standard costing principles conflict with modern business trends such as continual improvement. JIT organizations adopt a climate of continuous improvement, and the idea of normal levels of wastage and efficiency becomes unacceptable because of the drive to zero wastage and increasing efficiency.
2. Rapidly Outdated Standards: In modern business environments with rapidly changing conditions, standards quickly become out of date and lose their control and motivational effects.
3. Cost and Time: Standard costing and variance reporting may be time-consuming and expensive to operate.
4. Manager Understanding: Elaborate and complex variances, especially overhead variances, are often poorly understood by managers and prove ineffective for control purposes.
5. Quality Reduction Risk: Driving down costs often associates with reduced quality, externalization of costs, and lack of attention to individual customer needs.
6. Misleading Comparisons: Several reasons why actual results may differ from standard make variance analysis very difficult in practice:
Error in measuring the actual outcome
Outdated standard due to changes in operating conditions
Inefficient or efficient operations
Random, uncontrollable factors
Best Practices for Standard Costing Implementation
1. Set Current and Attainable Standards
Research recommends that firms should use current and attainable standards. This provides a realistic yet challenging target.
2. Correlate Technical Specifications and Scientific Measurements
Managers should correlate technical specifications and scientific measurements for materials and labour. This ensures standards are based on accurate data.
3. Ensure Competent Supervision
The cost accountant should have competent supervision and full interaction with factory workers.
4. Routine Plant and Machine Checks
Regular checking of plant and machines prevents breakdown and idle machine hours.
5. Provide Motivation
Motivation should be provided, a clear plan drawn, and measures taken for correction of variations.
6. Develop a Clear Variance Reporting Framework
Variance reports should be clear, timely, and focused on actionable items. Define clearly who is responsible for each variance type.
7. Use Technology to Improve Accuracy
Mobile scanning and guided workflows help reduce data latency and error rates. Cycle counts with variance thresholds can catch phantom stock early; on-device prompts during picking or issuing components can stop over-issues before they hit WIP.
8. Differentiate Between Planning and Operational Variances
Distinguish between variances within operational management’s control and those caused by external factors. This ensures accountability is assigned appropriately.
