Activity Based Costing (ABC) is a modern costing technique that allocates overhead costs to products and services based on the activities that generate those costs. Traditional costing methods usually allocate overheads using broad measures such as direct labour hours or machine hours, which may produce inaccurate product costs. ABC recognizes that activities consume resources and products consume activities. Therefore, costs are assigned according to the actual consumption of activities. ABC provides more accurate cost information and helps organizations improve pricing, profitability analysis, cost control, and strategic decision-making.

Meaning of Activity Based Costing

Activity Based Costing is a costing method that identifies activities within an organization and assigns the cost of each activity to products or services based on their consumption of those activities.

Allocation of Overheads under ABC

Stage 1. Identification of Overhead Costs

Cost activities are the various tasks, operations, or functions performed within an organization that consume resources and generate costs. In Activity Based Costing (ABC), activities are considered the real causes of costs because resources are consumed in performing activities, and products or services consume those activities. Understanding cost activities helps organizations allocate overhead costs accurately, identify inefficient processes, and improve cost management. Examples of cost activities include machine setup, purchasing, inspection, material handling, packaging, and customer service. Proper identification of cost activities enables managers to control costs, improve productivity, and make better strategic decisions.

Meaning of Cost Activities

Cost activities are organizational actions that require resources such as labour, machinery, materials, and time, thereby creating costs. Every business operation involves several activities, and each activity contributes to the total cost of producing goods or providing services.

Examples of cost activities include:

• Machine setup
• Purchasing materials
• Inspection
• Material handling
• Packaging
• Customer service
• Equipment maintenance

Examples of Cost Activities in Manufacturing

Examples of Cost Activities in Service Organizations

Cost drivers are one of the most important concepts in Activity Based Costing (ABC). A cost driver is a factor that causes the cost of an activity to occur or change. It establishes a direct relationship between activities and the products or services that consume those activities. Traditional costing systems often allocate overhead costs using a single basis such as labour hours or machine hours. However, ABC recognizes that different activities have different causes and therefore require different cost drivers. By identifying appropriate cost drivers, organizations can allocate costs accurately, improve cost control, and make better managerial decisions.

Meaning of Cost Drivers

Cost driver is any factor that influences the amount of cost incurred in performing an activity. It measures the frequency or intensity of an activity and provides the basis for assigning activity costs to products or services.

Definitions of Cost Drivers

• According to Kaplan and Cooper

A cost driver is a factor that causes or influences the cost of an activity and is used to allocate costs to products and services.

• According to Activity Based Costing

A cost driver is a measurable event or activity that causes resources to be consumed and costs to be incurred.

Examples of Cost Drivers

Activity Based Costing (ABC) is a modern costing technique that allocates overhead costs to products and services based on the activities that generate those costs. Traditional costing systems generally assign overheads using a single allocation base, such as direct labour hours or machine hours. Although traditional costing methods are simple and easy to apply, they often produce inaccurate product costs, especially in organizations with multiple products and high overhead expenses. Activity Based Costing overcomes these limitations by identifying various activities, creating cost pools, and using multiple cost drivers to allocate costs more precisely. ABC recognizes that products consume activities and activities consume resources. As a result, it provides more reliable information regarding product costs, profitability, and resource utilization. In today’s competitive business environment, organizations require accurate cost information for pricing, budgeting, and strategic decision-making. Therefore, ABC is considered superior to traditional costing because it improves cost accuracy, enhances managerial decisions, and supports better cost control and operational efficiency.

Advantages of ABC over Traditional Costing

Cost control is one of the most important objectives of management accounting in manufacturing organizations. Indian manufacturing firms operate in a highly competitive environment characterized by rising raw material prices, increasing labour costs, technological advancements, and global competition. To remain profitable and efficient, companies need effective mechanisms to monitor and control costs. One of the most widely used tools for this purpose is variance reporting.

Variance reporting involves comparing actual performance with predetermined standards or budgets and identifying deviations known as variances. These reports help management understand where costs are exceeding expectations and where operational efficiencies are being achieved. Indian manufacturing firms such as Tata Steel, Maruti Suzuki India Limited, and Asian Paints use variance reporting extensively for cost management and performance improvement.

Meaning of Cost Control through Variance Reporting

Cost control through variance reporting refers to the systematic process of:

• Establishing standard costs and budgets.
• Recording actual costs and performance.
• Comparing actual results with standards.
• Identifying favourable and adverse variances.
• Investigating the causes of variances.
• Taking corrective actions to improve efficiency.

The primary objective is to minimize unnecessary costs and maximize profitability.

Practical Applications in Indian Manufacturing Firms

• Automobile Industry

Companies such as Maruti Suzuki India Limited use variance reporting to monitor material consumption, labour efficiency, and production costs.

• Steel Industry

Tata Steel uses cost variance reports to control raw material expenses, energy costs, and production efficiency.

• Consumer Goods Industry

Asian Paints utilizes variance analysis to manage inventory costs and optimize production planning.

Types of Variance Reports Used

Variance reports are prepared to compare actual performance with predetermined standards and budgets. These reports help management identify deviations, determine their causes, and take corrective action. The major types of variance reports used in cost and management accounting are discussed below.

1. Material Variance Reports

Materil variance reports analyze the differences between standard material costs and actual material costs incurred during production. These reports help management determine whether materials are being purchased and used efficiently. Material variance reports include material cost variance, material price variance, material usage variance, material mix variance, and material yield variance. By studying these reports, managers can identify causes of higher costs such as increased material prices, excessive wastage, poor-quality materials, or inefficient production methods. The reports help improve purchasing decisions, inventory management, and production efficiency. They also enable management to take corrective actions for controlling material costs and reducing wastage. Regular analysis of material variances contributes to better cost management and increased profitability.

Example: A company sets a standard cost of ₹50 per kilogram for raw materials and expects to use 1,000 kilograms. However, it actually purchases 1,000 kilograms at ₹55 per kilogram. The additional ₹5 per kilogram creates a material price variance of ₹5,000 adverse. The variance report highlights this increase and helps management investigate supplier pricing and purchasing practices.

2. Labour Variance Reports

Labour variance reports compare actual labour costs and productivity with predetermined standards. These reports help management evaluate employee performance and identify areas where labour costs differ from expectations. Labour variance reports include labour cost variance, labour rate variance, labour efficiency variance, labour mix variance, and idle time variance. They provide information regarding wage increases, inefficient use of labour hours, and productivity issues. Management can use these reports to improve workforce planning, training, supervision, and incentive schemes. By regularly monitoring labour variances, organizations can reduce labour costs and increase production efficiency. These reports are particularly useful in manufacturing industries where labour expenses form a significant part of production costs.

Example: A factory establishes a standard of 500 labour hours at ₹100 per hour for producing a batch of products. The actual production requires 600 hours at ₹110 per hour. The labour variance report shows both labour rate and efficiency variances, enabling management to investigate the causes of higher labour costs and reduced productivity.

3. Overhead Variance Reports

Overhead variance reports measure the differences between budgeted overhead expenses and actual overhead costs incurred during production. These reports include fixed overhead variance, variable overhead variance, expenditure variance, efficiency variance, and capacity variance. Since overhead costs are indirect and difficult to trace to individual products, variance reports provide a systematic method of controlling these expenses. Managers use overhead variance reports to identify areas of excessive spending and determine whether resources are being utilized efficiently. The reports support budgeting, cost control, and performance evaluation. They also help organizations improve operational efficiency by identifying unnecessary expenses and areas requiring corrective action.

Example: A company budgets factory overhead expenses of ₹2,00,000 for a month. However, actual overhead expenses amount to ₹2,20,000. The overhead variance report indicates an adverse variance of ₹20,000. Management can investigate the reasons, such as increased electricity costs or maintenance expenses, and take measures to control future overhead spending.

4. Sales Variance Reports

Sales variance reports compare actual sales performance with budgeted sales targets. They analyze changes in revenue caused by differences in selling prices, quantities sold, and product mix. Sales variance reports include sales value variance, sales price variance, sales volume variance, sales mix variance, and sales quantity variance. These reports help management understand market conditions, customer preferences, and the effectiveness of marketing strategies. They also assist in evaluating sales department performance and developing future sales plans. Regular analysis of sales variances enables organizations to identify profitable products and take corrective action to improve sales performance.

Example: A company budgets the sale of 1,000 units at ₹100 per unit, expecting sales revenue of ₹1,00,000. However, it sells only 900 units at ₹95 per unit, generating revenue of ₹85,500. The sales variance report identifies adverse variances in both price and volume, helping management revise pricing and promotional strategies.

5. Profit Variance Reports

Profit variance reports analyze the differences between budgeted profit and actual profit earned during a period. These reports examine the factors responsible for changes in profitability, including variations in sales, production costs, and operating expenses. Profit variance reports provide management with a comprehensive understanding of business performance and assist in evaluating the effectiveness of managerial decisions. They also support strategic planning by identifying areas requiring improvement and highlighting profitable activities. Regular monitoring of profit variances helps organizations improve profitability and achieve long-term objectives.

Example: A company budgets a profit of ₹10,00,000 for the year but earns only ₹8,50,000. The profit variance report shows an adverse variance of ₹1,50,000. Further analysis reveals that increased material costs and lower sales volumes are responsible for the decline in profit. Management can then implement cost reduction and marketing strategies to improve future profitability.

6. Cost Variance Reports

Cost variance reports measure the overall differences between standard costs and actual costs incurred by the organization. These reports cover all major cost components, including materials, labour, overheads, administration expenses, and selling expenses. They provide management with a complete picture of cost performance and help identify areas where actual costs exceed planned costs. Cost variance reports support budgeting, performance evaluation, and cost control activities. By analyzing these reports, organizations can reduce unnecessary expenses and improve operational efficiency.

Example: A company budgets total production costs of ₹15,00,000 for a month. However, actual costs amount to ₹16,20,000. The cost variance report shows an adverse variance of ₹1,20,000. Further investigation identifies increases in material and labour costs. Management uses this information to implement corrective measures and improve cost management.

7. Production Variance Reports

Production variance reports compare actual production performance with planned production targets. These reports analyze differences in production quantity, machine efficiency, labour productivity, and resource utilization. Production variance reports help management identify operational inefficiencies and improve production planning. They provide valuable information regarding machine breakdowns, material shortages, and production delays. By studying production variances, organizations can improve productivity and reduce manufacturing costs.

Example: A factory plans to produce 10,000 units during a month but actually produces only 9,000 units because of machine breakdowns. The production variance report identifies an adverse production variance of 1,000 units. Management investigates the reasons and decides to improve preventive maintenance procedures to avoid similar problems in the future.

8. Budget Variance Reports

Budget variance reports compare actual performance with budgeted targets and identify deviations in revenues and expenditures. These reports help management determine whether operations are progressing according to plans. Budget variance reports support financial control and enable organizations to take timely corrective actions when performance deviates from expectations. They also assist in forecasting and resource allocation decisions.

Example: A company budgets marketing expenses of ₹5,00,000 for a quarter but actually spends ₹6,00,000. The budget variance report shows an adverse variance of ₹1,00,000. Management investigates the reasons and finds that additional promotional campaigns caused the increase. The information helps managers prepare more realistic budgets for future periods.

9. Departmental Variance Reports

Departmental variance reports are prepared separately for different departments to measure their performance and establish accountability. These reports provide detailed information regarding costs, revenues, and operational activities within each department. Managers use departmental variance reports to identify inefficiencies and evaluate the performance of department heads. These reports support responsibility accounting and improve coordination among departments.

Example: The production department has a budget of ₹20,00,000 for a month but incurs actual costs of ₹21,50,000. The departmental variance report shows an adverse variance of ₹1,50,000. Management investigates the reasons and discovers increased overtime expenses. Appropriate measures are then taken to improve workforce scheduling and control departmental costs.

10. Performance Variance Reports

Performance variance reports evaluate organizational efficiency by comparing actual performance with predetermined standards. These reports measure productivity, quality, efficiency, and time utilization. Performance variance reports help management identify areas requiring improvement and support continuous improvement initiatives. They are also useful for employee evaluation and performance appraisal.

Example: A manufacturing company sets a standard that each employee should produce 100 units per day. However, the actual output is only 85 units per employee. The performance variance report identifies a productivity variance and prompts management to investigate the reasons. Further analysis reveals insufficient training and machine downtime. Management then introduces training programs and maintenance schedules to improve productivity and achieve performance targets.

Process of Cost Control through Variance Reporting

Cost control through variance reporting is a systematic process in which actual performance is compared with predetermined standards or budgets to identify deviations and take corrective action. The process helps organizations monitor costs, improve efficiency, and achieve profitability. The major steps involved in the process are explained below.

Step 1. Setting Standards and Budgets

The first step in cost control through variance reporting is establishing standards and budgets for various cost elements such as materials, labour, overheads, and sales. Standard costs are predetermined costs that represent the expected level of performance under normal conditions. Budgets are prepared for different departments and activities based on these standards. Accurate standards and budgets provide a benchmark against which actual performance can be measured. If standards are unrealistic, variance analysis may produce misleading results. Therefore, organizations carefully determine standard prices, quantities, labour hours, and overhead rates. This step forms the foundation of the entire variance reporting process and ensures effective planning and control of organizational resources.

Example: A company sets a standard material cost of ₹100 per unit and budgets production of 5,000 units.

Step 2. Recording Actual Performance

The second step involves collecting and recording actual cost and performance information. Data regarding material purchases, labour hours, overhead expenses, and sales activities are gathered from accounting records and operational departments. Accurate and timely recording of actual performance is essential because variance calculations depend on the reliability of this information. Modern organizations often use ERP systems and computerized accounting software to record actual transactions automatically. Proper recording enables management to compare actual results with standards and identify deviations quickly. Inaccurate or incomplete data can result in misleading variance reports and poor decision-making.

Example: The company records that actual material cost incurred during production is ₹5,40,000 for producing 5,000 units.

Step 3. Comparison of Actual Performance with Standards

After actual data has been collected, management compares actual performance with predetermined standards and budgets. This comparison helps identify areas where performance differs from expectations. Differences may occur because of changes in prices, inefficient resource utilization, or unexpected business conditions. The comparison process forms the basis for variance analysis and highlights areas requiring managerial attention. By comparing actual and standard figures regularly, organizations can monitor performance continuously and detect problems at an early stage. This step provides management with meaningful information regarding cost control and operational efficiency.

Example: Standard material cost for 5,000 units is ₹5,00,000, but actual cost is ₹5,40,000, indicating a deviation of ₹40,000.

Step 4. Calculation of Variances

The next step is the calculation of variances. Variances are the differences between standard performance and actual performance. Organizations calculate various types of variances, including material variances, labour variances, overhead variances, and sales variances. Variances may be favourable when actual performance is better than expected or adverse when actual performance is worse than expected. The calculation process converts raw data into meaningful information that management can analyze. Modern accounting systems and spreadsheet applications make variance calculations faster and more accurate.

Example: Material Cost Variance:

MCV = Standard Cost – Actual Cost

= ₹5,00,000 – ₹5,40,000

= ₹40,000 (Adverse)

Step 5. Analysis and Investigation of Variances

After variances are calculated, management analyzes and investigates their causes. Significant favourable and adverse variances are examined to determine why they occurred. The investigation process may involve discussions with department managers, review of operational records, and examination of market conditions. Understanding the reasons behind variances helps management distinguish between controllable and uncontrollable factors. This step is essential because variance figures alone do not explain the reasons for performance deviations.

Example: An adverse material variance may be caused by increased supplier prices or excessive wastage of raw materials during production.

Step 6. Reporting of Variances

Once variances have been analyzed, detailed variance reports are prepared and communicated to managers and department heads. These reports summarize deviations and provide information regarding their causes and impact on organizational performance. Variance reports may be prepared weekly, monthly, or quarterly depending on organizational requirements. Reports often include tables, graphs, and dashboards to improve understanding and facilitate decision-making. Effective reporting ensures that managers receive timely information and can respond quickly to problems.

Example: The production manager receives a report showing material cost variance of ₹40,000 adverse and labour efficiency variance of ₹20,000 favourable.

Step 7. Taking Corrective Action

The final step in cost control through variance reporting is taking corrective action to improve future performance. Management develops and implements strategies to eliminate the causes of adverse variances and maintain favourable variances. Corrective actions may include improving purchasing procedures, providing employee training, reducing wastage, revising budgets, or modifying production methods. Continuous monitoring ensures that corrective measures are effective and contribute to better performance in future periods.

Example: If material costs have increased because of high supplier prices, management may negotiate better contracts or identify alternative suppliers.

Challenges Faced in Cost Control through Variance Reporting

• Difficulty in Setting Accurate Standards

One of the major challenges in variance reporting is establishing accurate standards for materials, labour, and overhead costs. Standards that are too high or too low can produce misleading variances and result in incorrect managerial decisions. Market conditions, inflation, and changes in production methods make it difficult to determine realistic standards. Inaccurate standards reduce the effectiveness of variance analysis because variances may reflect poor planning rather than actual performance problems. Therefore, organizations need to review and update standards regularly to ensure that variance reports remain meaningful and useful for cost control and performance evaluation.

• Fluctuating Raw Material Prices

Indian manufacturing firms frequently face fluctuations in the prices of raw materials due to changes in demand, supply, inflation, government policies, and international market conditions. Sudden increases in material prices often create adverse variances that are beyond the control of management. These fluctuations make it difficult to compare actual costs with standard costs accurately. Variance reports may therefore show large deviations that do not necessarily indicate inefficiency. Managing the impact of changing material prices remains a significant challenge for organizations and requires continuous monitoring of market conditions and regular revision of cost standards.

• Large Volume of Data

Manufacturing organizations generate enormous amounts of data relating to production, materials, labour, inventory, and sales. Collecting, processing, and analyzing this information for variance reporting can be difficult and time-consuming. Manual handling of large data sets increases the possibility of errors and delays in reporting. Even computerized systems may become complex when dealing with extensive information. Managers may find it challenging to identify significant variances among numerous reports and data entries. Therefore, handling large volumes of information remains an important challenge and requires efficient information systems and effective data management practices.

• Requirement of Skilled Personnel

Variance reporting requires employees who possess knowledge of cost accounting, budgeting, and data analysis techniques. Skilled personnel are needed to prepare reports, interpret variances, and recommend corrective actions. Many organizations face difficulties in finding and retaining qualified professionals with expertise in management accounting and information systems. Training employees also involves additional costs and time. Without adequate skills, variance reports may be prepared incorrectly or interpreted improperly, reducing their usefulness. Consequently, the requirement for skilled personnel becomes a major challenge in implementing effective variance reporting systems.

• Dependence on Technology and ERP Systems

Modern variance reporting systems depend heavily on computerized accounting software and ERP systems. Technical failures, software errors, and system breakdowns can disrupt the preparation and analysis of variance reports. Organizations also face challenges related to system maintenance, upgrades, and cybersecurity. Dependence on technology means that inaccurate data entry or system malfunctions can affect the reliability of reports. Small and medium-sized firms may not always have sufficient financial resources to invest in advanced ERP systems. Therefore, technological dependence and system-related issues represent significant challenges in cost control through variance reporting.

• Resistance to Change

Employees and managers sometimes resist the introduction of variance reporting systems because they fear increased monitoring and accountability. New reporting procedures may require changes in existing practices and additional responsibilities. Resistance from employees can slow implementation and reduce the effectiveness of variance analysis. Organizations may need to spend considerable time and resources on training and change management programs to overcome this resistance. Therefore, managing organizational change and gaining employee support remain important challenges in successfully implementing variance reporting systems.

• Difficulty in Identifying Causes of Variances

Variance reports show the amount of deviation from standards but do not always explain the reasons behind those deviations. Determining the exact causes of variances can be difficult because several factors may contribute simultaneously. For example, an adverse material variance may result from increased prices, poor-quality materials, or production inefficiencies. Management must conduct detailed investigations to identify the real causes of variances. This process can be time-consuming and may delay corrective actions. Consequently, identifying the underlying reasons for variances is a major challenge in effective cost control.

• Rapid Changes in Business Environment

The business environment is constantly changing because of technological developments, changing customer preferences, economic conditions, and government regulations. These changes can quickly make existing standards and budgets outdated. Variance reports based on outdated standards may provide misleading information and reduce the effectiveness of managerial decisions. Organizations need to review and revise their standards regularly to reflect current conditions. Keeping pace with a rapidly changing environment is therefore a significant challenge for firms relying on variance reporting for cost control and performance management.

Consequently, ERP-based variance reporting becomes an essential tool for strategic planning, cost control, and continuous performance improvement.

Process of Integration of Variance Reports with ERP Software

Step 1. Collection of Data from ERP Modules

The first step in the integration process is the collection of data from various ERP modules such as purchasing, production, inventory, payroll, accounting, and sales. Each department records its transactions in the ERP system, creating a centralized database. Information relating to material costs, labour hours, overhead expenses, and sales revenue is automatically gathered by the system. Since data is entered only once and shared across departments, duplication and inconsistencies are minimized. The centralized collection of information ensures that variance calculations are based on complete and reliable data, improving the accuracy and effectiveness of variance reporting.

Step 2. Establishment of Standards and Budgets

Before variances can be calculated, organizations need to establish standard costs and budgeted figures. Standards for material consumption, labour rates, overhead costs, and sales targets are entered into the ERP system. These standards serve as benchmarks against which actual performance is measured. Budget information is usually prepared by management and uploaded into the ERP database. The system stores these standards and makes them available for comparison whenever actual transactions occur. Proper establishment of standards is essential because inaccurate standards can lead to misleading variance reports and poor managerial decisions.

Step 3. Comparison of Actual Data with Standards

After collecting actual data and storing standard information, the ERP system automatically compares actual performance with predetermined standards. The system examines differences in material costs, labour costs, overhead expenses, and sales figures. This comparison process identifies deviations between planned and actual performance. Since the comparison is performed automatically, it eliminates manual calculations and significantly reduces the chances of computational errors. The comparison process provides the foundation for variance analysis and helps management identify areas where organizational performance differs from expectations.

Step 4. Automatic Calculation of Variances

Once actual and standard data have been compared, the ERP system automatically calculates various types of variances. These include material cost variance, labour efficiency variance, overhead expenditure variance, and sales volume variance. Built-in formulas and reporting tools perform calculations instantly whenever new data is entered into the system. Automatic calculation reduces the time required for preparing reports and improves accuracy. Managers no longer need to perform complicated calculations manually, allowing them to focus on interpreting results and taking corrective actions.

Step 5. Generation of Variance Reports and Dashboards

The ERP system then converts variance calculations into detailed reports and graphical dashboards. These reports present favourable and adverse variances in a clear and organized manner. Dashboards may include charts, graphs, tables, and performance indicators that make information easier to understand. Reports can be customized according to the requirements of different departments and management levels. Real-time dashboards allow managers to monitor performance continuously and identify problem areas quickly. The reporting stage transforms raw data into meaningful information that supports effective managerial control and decision-making.

Step 6. Distribution and Communication of Reports

After variance reports have been generated, they are distributed electronically to managers and department heads through the ERP system. Authorized users can access reports from any location and review performance information immediately. Automated distribution ensures that decision-makers receive timely information without delays. Reports can also be shared during meetings and presentations to facilitate communication among departments. Effective distribution of variance reports improves coordination and ensures that all responsible managers are aware of performance deviations and their potential impact on organizational objectives.

or

SVV = (AQ×AP) − (BQ×SP)

Where:

• AQ = Actual Quantity Sold
• AP = Actual Selling Price
• BQ = Budgeted Quantity
• SP = Standard Selling Price

Alternative Formula

SVV = SPV+SVV(Volume)

Where:

• SPV = Sales Price Variance
• SVV (Volume) = Sales Volume Variance

Interpretation of Sales Value Variance

Favourable Variance (F)

When:

Actual Sales > Budgeted Sales

This means the company has generated more revenue than expected.

Adverse or Unfavourable Variance (A)

When:

Actual Sales < Budgeted Sales

This means the company has generated less revenue than expected.

Example 1

Budgeted Sales

• Quantity = 1,000 units
• Selling Price = ₹100 per unit

Budgeted Sales Value:

1,000×100=₹1,00,000

Actual Sales

• Quantity = 1,200 units
• Selling Price = ₹95 per unit

Actual Sales Value:

1,200×95=₹1,14,000

$$=₹1,14,000$$

Sales Value Variance

SVV = ₹1,14,000−₹1,00,000

$$=₹14,000(F)$$

4. Labour Mix Variance (LMV)

Labour Mix Variance (LMV) is the portion of Labour Efficiency Variance that arises because the actual composition or mix of different categories of labour differs from the standard labour mix.

It occurs when an organization employs workers in proportions different from the predetermined standard, such as using more unskilled workers and fewer skilled workers or vice versa. Labour Mix Variance helps management determine whether changes in the labour composition have increased or reduced labour costs and efficiency.

Definition

Labour Mix Variance is the difference between:

The standard cost of the revised standard labour mix and the standard cost of the actual labour mix.

Formula

LMV = ∑SR(RSH−AH)

Where:

• SR = Standard Rate per Hour
• RSH = Revised Standard Hours
• AH = Actual Hours Worked

Calculation of Revised Standard Hours (RSH)

RSH = (Total Actual Hours / Total Standard Hours) × Standard Hours of each grade

Interpretation

Favourable Variance (F)

When the actual labour mix is more economical than the standard mix.

Adverse or Unfavourable Variance (A)

When the actual labour mix is less economical and increases labour cost.

Example

Standard Labour Mix

Actual Labour Mix

Step 1: Calculate Revised Standard Hours

Since total actual hours equal total standard hours, the Revised Standard Hours remain:

• Skilled Workers = 60 hours
• Unskilled Workers = 40 hours

Step 2: Calculate Labour Mix Variance

Skilled Workers

LMV = 20(60−50)

$$=₹200(F)$$

Unskilled Workers

LMV=10(40−50)

$$=₹100(A)$$

Total Labour Mix Variance

LMV = ₹200(F)−₹100(A)

$$=₹100(F)$$

Therefore, the Labour Mix Variance is ₹100 Favourable.

• Time-consuming calculations.
• Ignores qualitative aspects of labour.
• Difficult in service industries.
• External factors may influence labour availability.

Standard costing requires the establishment of predetermined standards for materials, labour, and overheads. These standards serve as benchmarks for measuring actual performance and controlling costs. Properly established standards help organizations improve efficiency, reduce wastage, and enhance profitability.

1. Setting Standards for Material

Material standards represent the predetermined quantity and price of materials that should be used to produce a product under efficient operating conditions.

Material standards consist of two elements:

• Standard Material Quantity
• Standard Material Price

(A) Setting Standard Material Quantity

Standard material quantity refers to the amount of material that should be consumed in producing one unit of output.

Factors Considered

• Product specifications
• Engineering studies
• Past production records
• Material quality
• Normal wastage and spoilage
• Production methods

Formula

Standard Material Cost = Standard Quantity × Standard Price

Example

A product requires:

• Raw Material = 5 kg
• Normal Wastage = 0.5 kg

Standard Quantity:

5 + 0.5 = 5.5 kg

Thus, the standard quantity is 5.5 kg per unit.

(B) Setting Standard Material Price

Standard material price is the predetermined price that the organization expects to pay for materials.

Factors Considered

• Market prices
• Supplier quotations
• Transportation costs
• Import duties and taxes
• Discounts and trade terms
• Economic conditions

Example

Expected purchase price = ₹40 per kg.

Therefore,

Standard Material Price = ₹40 per kg.

Calculation of Standard Material Cost

If:

• Standard Quantity = 5.5 kg
• Standard Price = ₹40 per kg

Then,

$$\text{Standard Material Cost}=5.5\times 40$$ $$=₹220$$

2. Setting Standards for Labour

Labour standards represent the predetermined labour cost required to produce one unit of output under efficient working conditions.

Labour standards consist of:

• Standard Labour Time
• Standard Labour Rate

(A) Setting Standard Labour Time

Standard labour time is the amount of time that should be taken by workers to complete a task.

Factors Considered

• Time and motion studies
• Past experience
• Skill of workers
• Working conditions
• Machine efficiency
• Normal interruptions and rest periods

Example

A worker normally takes:

• Actual production time = 3 hours
• Allowance for fatigue = 0.25 hour

Standard Labour Time:

3 + 0.25

$$=3.25\text{ hours}$$

(B) Setting Standard Labour Rate

Standard labour rate is the predetermined wage rate expected to be paid to workers.

Factors Considered

• Labour agreements
• Government regulations
• Wage policies
• Skill requirements
• Market wage rates
• Employee benefits

Example

Expected wage rate:

₹100 per hour.

Therefore,

Standard Labour Rate = ₹100 per hour.

Calculation of Standard Labour Cost

If:

• Standard Labour Time = 3.25 hours
• Standard Wage Rate = ₹100 per hour

Then,

Standard Labour Cost = 3.25 × 100

= ₹325

3. Setting Standards for Overheads

Overhead standards refer to the predetermined indirect costs expected to be incurred during production.

Overheads are generally classified into:

• Variable Overheads
• Fixed Overheads

(A) Setting Standard Variable Overhead

Variable overheads vary directly with the level of production.

Examples:

• Power expenses
• Indirect materials
• Indirect labour

Factors Considered

• Expected production volume
• Historical cost data
• Production methods
• Machine usage

Formula

Variable Overhead Rate = Estimated Variable Overheads / Estimated Activity Level​

Example

Estimated Variable Overheads = ₹1,20,000

Estimated Labour Hours = 6,000 hours

= 1,20,000 / 6,000

=₹ 20 per hour

(B) Setting Standard Fixed Overhead

Fixed overheads remain constant irrespective of production volume.

Examples:

• Factory rent
• Depreciation
• Insurance
• Salaries of supervisors

Formula

Fixed Overhead Rate = Budgeted Fixed Overheads / Normal Activity Level​

Example

Budgeted Fixed Overheads = ₹3,00,000

Normal Labour Hours = 6,000 hours

= 3,00,000 / 6,000

=₹50 per hour

Calculation of Standard Overhead Cost

If:

• Variable Overhead Rate = ₹20 per hour
• Fixed Overhead Rate = ₹50 per hour
• Standard Hours = 3.25 hours

Variable Overhead Cost

3.25 × 20

= ₹65

Fixed Overhead Cost

3.25 × 50 

= ₹162.50

Total Standard Overhead Cost

65 + 162.50

= ₹227.50
