ABC, or Activity-Based Costing, is a costing methodology that focuses on identifying and assigning costs to specific activities that consume resources within an organization. It provides a more accurate and detailed understanding of cost drivers and cost behavior, allowing for better cost allocation and decision-making.

ABC departs from traditional costing methods that rely heavily on volume-based allocation, such as direct labor hours or machine hours. Instead, ABC identifies activities performed within an organization and allocates costs to those activities based on their consumption of resources. It recognizes that activities drive costs and that products or services consume activities in varying degrees.

Definition

According to the Chartered Institute of Management Accountants (CIMA):

“Activity Based Costing is an approach to the costing and monitoring of activities which involves tracing resource consumption and costing final outputs.”

Concept of Activity Based Costing

The basic concept of ABC is:

Resources → Activities → Cost Objects (Products or Services)

• Resources such as labour, electricity, and machinery create costs.
• Activities consume these resources.
• Products consume activities.
• Therefore, costs are assigned to products based on their use of activities.

Features of Activity Based Costing (ABC)

• Activity-Oriented Approach

The most important feature of Activity Based Costing is its activity-oriented approach. ABC focuses on activities as the primary source of costs rather than departments or products. It recognizes that products consume activities and activities consume resources. Therefore, costs are first assigned to activities and then allocated to products based on their usage of those activities. This approach provides a better understanding of how costs are incurred within an organization. By concentrating on activities, management can identify inefficient processes and opportunities for improvement. Thus, the activity-oriented approach makes ABC an effective tool for cost management and operational efficiency.

• Use of Multiple Cost Driver

Unlike traditional costing systems that use a single allocation base, Activity Based Costing uses multiple cost drivers to allocate overhead costs. Different activities have different causes, and each activity requires a separate cost driver. Examples include machine hours, purchase orders, production setups, and inspections. The use of multiple cost drivers ensures that costs are assigned more accurately according to the actual consumption of resources. This feature improves the reliability of product costing and provides management with better information for decision-making. Consequently, the use of multiple cost drivers is a major characteristic that distinguishes ABC from traditional costing methods.

• Accurate Allocation of Overhead Costs

Activity Based Costing provides a more accurate method of allocating overhead costs to products and services. Traditional costing methods often distort product costs by allocating overheads using broad averages. ABC identifies the activities that generate costs and assigns those costs according to actual resource consumption. This approach reduces cost distortions and ensures that each product bears a fair share of overhead expenses. Accurate cost allocation improves pricing decisions, profitability analysis, and resource management. Therefore, one of the most significant features of ABC is its ability to provide precise and reliable information regarding the actual cost of products and services.

• Creation of Cost Pools

Activity Based Costing groups similar expenses into cost pools before allocating them to products or services. A cost pool is a collection of costs associated with a particular activity, such as machine setup, inspection, or material handling. Creating cost pools simplifies the allocation process and improves the accuracy of cost assignment. Each cost pool is linked to an appropriate cost driver that reflects the consumption of resources. This feature allows management to understand the cost of individual activities and identify areas requiring improvement. Consequently, cost pools play an essential role in making ABC a systematic and efficient costing method.

• Identification of Value-Added and Non-Value-Added Activities

A significant feature of Activity Based Costing is its ability to distinguish between value-added and non-value-added activities. Value-added activities increase the usefulness of a product or service, while non-value-added activities create costs without providing customer benefits. Examples of non-value-added activities include excessive inspections, unnecessary movement of materials, and rework. By identifying such activities, management can eliminate waste and improve operational efficiency. This feature supports cost reduction and continuous improvement programs. Therefore, the identification of value-added and non-value-added activities makes ABC an effective tool for improving productivity and reducing unnecessary costs.

• Better Cost Visibility

Activity Based Costing provides detailed information regarding how and where costs are incurred within an organization. Managers can clearly see the relationship between activities and resource consumption. This improved cost visibility enables management to identify costly activities and areas of inefficiency. Better understanding of cost behaviour supports budgeting, planning, and strategic decision-making. It also helps managers determine which products, services, or customers consume the most resources. Consequently, better cost visibility is an important feature of ABC because it provides meaningful information that supports cost control and enhances organizational performance.

• Supports Managerial Decision-Making

Activity Based Costing generates accurate and detailed information that supports various managerial decisions. Managers can use ABC information for pricing decisions, product mix decisions, outsourcing decisions, budgeting, and profitability analysis. Since costs are allocated according to actual activities, management receives reliable information regarding the profitability of products and services. This feature reduces the chances of making incorrect decisions based on distorted cost data. Better decision-making improves operational efficiency and profitability. Therefore, the ability of ABC to support managerial decision-making is one of its most valuable features and contributes significantly to organizational success.

• Suitable for Complex Manufacturing Environments

Activity Based Costing is particularly suitable for organizations that manufacture multiple products and incur significant overhead costs. In complex manufacturing environments, traditional costing methods may fail to allocate costs accurately because products consume resources differently. ABC overcomes this problem by identifying various activities and allocating costs based on actual consumption. It is especially useful in industries with diverse product lines, automated production systems, and high indirect costs. This feature enables organizations to obtain accurate product costs and improve cost management. Therefore, ABC is highly suitable for modern manufacturing environments characterized by complexity and technological advancement.

Consequently, Activity Based Costing has significant importance because it provides meaningful information that strengthens managerial planning, control, and strategic decision-making processes.

• Identifies Non-Value-Added Activities

One of the significant contributions of Activity Based Costing is its ability to identify non-value-added activities that increase costs without creating customer value. Examples include unnecessary inspections, excessive material handling, and repeated machine setups. By identifying these activities, management can eliminate or reduce them and improve operational efficiency. The elimination of non-value-added activities reduces costs, shortens production cycles, and improves productivity. Organizations can then focus their resources on activities that directly contribute to customer satisfaction and profitability. Therefore, ABC plays an important role in continuous improvement and cost reduction initiatives.

• Improves Resource Utilization

Activity Based Costing helps organizations utilize resources more efficiently by showing how activities consume resources such as labour, machinery, and materials. Managers can identify activities that use excessive resources and take corrective measures to improve efficiency. ABC provides information that supports better planning and allocation of resources across different products and departments. Improved resource utilization reduces waste, increases productivity, and lowers operating costs. Efficient use of resources also enhances competitiveness and profitability. Therefore, one of the major significances of Activity Based Costing is its contribution to effective resource management and improved organizational performance.

• Provides Competitive Advantage

In today’s highly competitive business environment, organizations require accurate cost information and efficient operations to survive and grow. Activity Based Costing provides detailed insights into cost behavior and profitability, enabling firms to make better strategic decisions. Companies can improve pricing, eliminate waste, control costs, and focus on profitable products and customers. These improvements enhance operational efficiency and customer satisfaction, leading to a stronger market position. Organizations using ABC can respond more effectively to changing market conditions and competitive pressures. Therefore, Activity Based Costing provides a significant competitive advantage and contributes to long-term business success and sustainability.

Steps in Activity Based Costing (ABC)

1. Application in Machine Setup Activities

Activity Based Costing is widely applied in machine setup activities in manufacturing organizations. Machine setup involves preparing machines for different production runs, adjusting equipment, and changing tools according to product specifications. ABC identifies setup activities as separate cost pools and allocates setup costs based on the number of setups required by each product. Products requiring frequent setups receive a higher share of setup costs than products produced in large batches. This method provides more accurate product costing and helps management understand the actual cost of production. Consequently, ABC improves pricing decisions and production planning in manufacturing organizations.

2. Application in Material Handling Activities

Manufacturing firms frequently move raw materials, components, and finished goods between departments and production stages. Activity Based Costing applies to material handling activities by creating a separate cost pool for material movement expenses. Costs such as transportation, labour, storage, and equipment operation are allocated according to the number of material movements or handling hours. Products that require frequent movement of materials receive a greater proportion of these costs. This application enables management to identify products that consume excessive handling resources and develop strategies to improve efficiency. Therefore, ABC contributes significantly to better material management and cost control.

3. Application in Purchasing Activities

Purchasing activities involve acquiring raw materials, processing purchase orders, negotiating with suppliers, and maintaining procurement records. Activity Based Costing treats purchasing as a separate activity and allocates purchasing costs based on the number of purchase orders or supplier transactions. Products requiring frequent purchases consume more purchasing resources and therefore receive a larger allocation of costs. This application helps management understand the true cost of procurement activities and improve purchasing efficiency. ABC also supports supplier evaluation and inventory management decisions. Consequently, applying ABC to purchasing activities results in better cost control and more efficient procurement management.

4. Application in Quality Inspection Activities

Quality inspection is an essential activity in manufacturing organizations to ensure products meet required standards. Activity Based Costing identifies inspection activities separately and allocates their costs based on the number of inspections performed.

By identifying high-cost activities, organizations can improve efficiency and reduce unnecessary expenses. Therefore, the application of ABC in IT services enhances cost control, improves decision-making, and contributes to increased profitability and customer satisfaction.

Fundamentals of Activity Based Costing (ABC)

1. Activities Consume Resources

The first and most important fundamental of Activity Based Costing is that activities consume resources. Every activity performed in an organization requires resources such as labour, machinery, electricity, materials, and time. These resources create costs, and the costs arise because activities are being carried out. For example, machine setup activities require technicians, equipment, and energy, all of which involve expenses. Similarly, quality inspection activities require inspectors, testing equipment, and administrative support. ABC recognizes that resources are not consumed directly by products; instead, activities use resources and generate costs. Understanding this relationship helps management identify which activities consume the most resources and where cost reduction efforts should be concentrated. By measuring resource consumption accurately, organizations can improve cost control and operational efficiency. This principle also helps managers eliminate unnecessary activities and optimize resource utilization. Therefore, the concept that activities consume resources forms the foundation of Activity Based Costing and provides the basis for accurate cost allocation, better budgeting, and improved managerial decision-making in modern business organizations.

Example: Machine setup activities consume technician time and equipment resources.

Understanding the relationship between activities and resources helps management identify the causes of costs and control unnecessary expenses.

2. Products Consume Activities

Another fundamental principle of Activity Based Costing is that products and services consume activities. Different products require different production processes, inspections, setups, and handling activities. Consequently, products should bear costs according to the activities they consume rather than through arbitrary overhead allocations. For example, a customized product may require several machine setups and inspections, while a standard product may require very few. Traditional costing methods often ignore these differences and allocate costs equally, leading to inaccurate product costs. ABC solves this problem by tracing activities to products based on actual usage. This principle enables management to determine the true cost of producing each product and identify profitable and unprofitable products. It also supports better pricing decisions and product mix decisions. By understanding the activities consumed by products, managers can improve production planning and resource allocation. Therefore, the principle that products consume activities is central to ABC because it ensures fair and accurate assignment of overhead costs and provides reliable information for strategic decision-making and profitability analysis.

Example: A customized product may require more inspections and machine setups than a standard product.

This principle ensures that costs are allocated fairly according to actual resource usage.

3. Activities are the Basis of Cost Allocation

Activity Based Costing differs from traditional costing systems because it uses activities as the basis for cost allocation. In traditional systems, overhead costs are often allocated using a single base such as labour hours or machine hours. However, this method may not reflect the actual consumption of resources by products. ABC identifies various activities performed in the organization and assigns costs to those activities before allocating them to products. Examples of activities include purchasing, material handling, inspection, machine setup, and packaging. Since each activity generates costs differently, allocating costs through activities produces more accurate product costs. This approach helps management understand how costs arise and which activities contribute most to overhead expenses. By focusing on activities, organizations can identify inefficient processes and implement cost reduction strategies. The activity-based approach also supports continuous improvement by highlighting non-value-added activities that increase costs without benefiting customers. Therefore, using activities as the basis of cost allocation is a fundamental principle that improves cost accuracy and managerial decision-making.

Example: Inspection costs are allocated according to the number of inspections required by each product.

This approach provides more accurate cost information than traditional costing systems.

4. Identification of Cost Drivers

Cost drivers are factors that cause activities to occur and generate costs. The identification of cost drivers is one of the fundamental principles of Activity Based Costing because it establishes a relationship between activities and products. Different activities require different cost drivers. For example, machine setup costs may be driven by the number of setups, inspection costs by the number of inspections, and purchasing costs by the number of purchase orders. Selecting appropriate cost drivers is essential because inaccurate cost drivers can distort product costs and lead to incorrect managerial decisions. Cost drivers help measure the actual consumption of activities by products and ensure that costs are allocated fairly. They also provide valuable information about the factors influencing organizational costs. By analyzing cost drivers, managers can identify opportunities for improving efficiency and reducing expenses. Therefore, the identification of cost drivers is a fundamental aspect of ABC because it enhances cost accuracy, improves resource allocation, and supports effective planning, control, and decision-making within the organization.

Examples of Cost Drivers:

• Number of setups
• Machine hours
• Purchase orders
• Number of inspections
• Material movements

Selecting appropriate cost drivers is essential for accurate cost allocation.

5. Creation of Cost Pools

A cost pool is a collection of costs associated with a specific activity or group of similar activities. The creation of cost pools is a fundamental element of Activity Based Costing because it simplifies the process of assigning overhead costs. Instead of allocating all indirect costs together, ABC groups similar expenses into separate pools such as machine setup costs, inspection costs, material handling costs, and purchasing costs. Each cost pool is then linked to an appropriate cost driver. This approach improves cost accuracy because it recognizes that different activities consume resources differently. Cost pools also provide managers with detailed information about the costs of individual activities, enabling them to identify expensive processes and areas requiring improvement. By analyzing cost pools, organizations can control overhead expenses more effectively and improve operational efficiency. Therefore, the creation of cost pools is an essential principle of ABC that supports accurate cost allocation, better cost management, and improved managerial decision-making.

Examples of Cost Pools:

• Machine setup cost pool
• Quality inspection cost pool
• Material handling cost pool

Cost pools simplify the allocation process and improve cost accuracy.

6. Use of Multiple Cost Drivers

One of the important fundamentals of Activity Based Costing is the use of multiple cost drivers for allocating overhead costs. Traditional costing methods generally use a single allocation base, such as direct labour hours or machine hours, which may not accurately reflect the consumption of resources. ABC recognizes that different activities are influenced by different factors and therefore require separate cost drivers. For example, purchasing costs may depend on the number of purchase orders, while maintenance costs may depend on machine hours. Using multiple cost drivers improves the precision of cost allocation and provides more reliable product costs. It also helps managers understand the causes of costs and identify opportunities for improving efficiency. Multiple cost drivers enable organizations to allocate costs according to actual activity consumption rather than broad averages. Therefore, the use of multiple cost drivers is a fundamental principle of ABC that enhances cost accuracy, supports better pricing decisions, and improves overall managerial effectiveness.

Example:

• Setup costs → Number of setups
• Maintenance costs → Machine hours
• Purchasing costs → Number of purchase orders

The use of multiple drivers improves the precision of cost allocation.

7. Two-Stage Cost Allocation Process

Activity Based Costing follows a two-stage cost allocation process that distinguishes it from traditional costing methods. In the first stage, resource costs are assigned to activities using resource drivers. In the second stage, activity costs are allocated to products or services based on activity cost drivers. This systematic approach ensures that overhead costs are assigned according to the actual consumption of resources and activities. The two-stage process provides a more accurate representation of cost behaviour and reduces the possibility of cost distortions. It also enables managers to understand how resources are consumed by activities and how activities are consumed by products. This information supports effective planning, budgeting, and performance evaluation. By following a structured allocation process, organizations can obtain reliable cost information and make better managerial decisions. Therefore, the two-stage cost allocation process is a fundamental aspect of ABC and contributes significantly to accurate product costing and efficient resource management.

ABC follows a two-stage allocation process:

Stage 1

Allocate resource costs to activities.

Stage 2

Allocate activity costs to products or services.

This systematic approach ensures accurate distribution of overhead costs.

8. Identification of Value-Added and Non-Value-Added Activities

Activity Based Costing distinguishes between value-added and non-value-added activities. Value-added activities are those that increase the usefulness of a product or service from the customer’s perspective, such as assembly and product design. Non-value-added activities, such as excessive inspections, unnecessary movement of materials, and rework, increase costs without adding value. Identifying these activities is one of the fundamental principles of ABC because it helps organizations eliminate waste and improve efficiency. By reducing or eliminating non-value-added activities, organizations can lower operating costs, improve productivity, and enhance customer satisfaction. This principle also supports continuous improvement programs and encourages managers to focus on activities that contribute directly to organizational objectives. Therefore, the identification of value-added and non-value-added activities is an important foundation of ABC because it promotes cost reduction, operational efficiency, and long-term organizational competitiveness.

ABC distinguishes between:

Value-Added Activities

Activities that increase customer value.

Example: Product assembly.

Non-Value-Added Activities

Activities that increase costs without adding value.

Example: Excessive inspections.

This distinction helps organizations eliminate waste and improve efficiency.

Marginal Costing

Marginal Costing is a cost accounting technique that focuses on analyzing the behavior of costs in relation to changes in production volume. It classifies costs into fixed and variable components, where only variable costs are considered in determining the cost of production. Fixed costs are treated as period costs and charged to the profit and loss account. The technique is based on the contribution margin, calculated as sales revenue minus variable costs, which aids in assessing profitability and decision-making. Marginal costing is widely used for break-even analysis, pricing decisions, and evaluating the impact of production changes on overall profitability.

Characteristics of Marginal Costing

• Separation of Fixed and Variable Costs

In marginal costing, costs are clearly divided into fixed and variable components. Variable costs change in direct proportion to changes in production levels, while fixed costs remain constant regardless of output. This distinction enables businesses to focus on the costs that fluctuate with production and determine their contribution to profit.

• Fixed Costs Treated as Period Costs

Marginal costing treats fixed costs as period costs, meaning they are not allocated to the cost of production. Fixed costs are directly charged to the profit and loss account in the period in which they are incurred, rather than being absorbed into the cost of goods sold.

• Contribution Margin

The key concept in marginal costing is the contribution margin, which is calculated as sales revenue minus variable costs. The contribution margin reflects the amount available to cover fixed costs and generate profit. It helps in analyzing the profitability of individual products or services and assists in making decisions about pricing and production.

• Helps in Break-even Analysis

Marginal costing is particularly useful for conducting break-even analysis. By calculating the contribution margin, businesses can determine the level of sales required to cover both fixed and variable costs. This aids in assessing the minimum sales needed to avoid losses and helps set realistic sales targets.

• Simplifies Decision-Making

Marginal costing provides clear insights into the impact of variable costs on profitability. It helps management make informed decisions regarding pricing, product mix, make-or-buy decisions, and determining the optimal production level. Since fixed costs are considered period costs and do not affect the decision-making process, it simplifies complex decisions.

• Short-Term Focus

Marginal costing is primarily used for short-term decision-making. It provides valuable information for day-to-day operations and helps businesses analyze the immediate impact of decisions such as pricing adjustments, special orders, and cost control measures. It is less suitable for long-term strategic decisions involving large investments or capital expenditures.

• Flexibility

Marginal costing offers flexibility in cost allocation. It is adaptable to different types of businesses and production processes, making it an effective tool for cost analysis across various industries. Its simplicity in classifying costs makes it easier to adjust and implement as needed.

• Non-compliance with Financial Accounting Standards

Marginal costing does not adhere to traditional financial accounting principles, which require the allocation of both fixed and variable costs to the cost of goods sold. As a result, marginal costing is not suitable for external reporting, but it is invaluable for internal decision-making and performance analysis.

Absorption Costing

Absorption Costing, also known as full costing, is a cost accounting method that allocates all manufacturing costs—both fixed and variable—to the cost of a product. This includes direct materials, direct labor, and both variable and fixed manufacturing overheads. Under absorption costing, the total cost of production is charged to units produced, ensuring that all incurred costs are absorbed by the products. It is widely used for financial reporting and compliance with accounting standards, as it provides a complete view of production costs. However, it may obscure cost behavior, as fixed costs are distributed across all units, affecting cost analysis.

Characteristics of Absorption Costing

• Inclusion of All Manufacturing Costs

Absorption costing considers all production-related costs, including both fixed and variable costs. Direct costs such as materials and labor, as well as indirect costs (overheads), are included in the product cost. These indirect costs are apportioned across all units produced, ensuring that each unit absorbs a portion of the fixed costs.

• Fixed Costs are Included in Product Cost

A defining characteristic of absorption costing is that fixed costs (e.g., rent, salaries of permanent employees) are included in the product cost. Unlike marginal costing, where fixed costs are treated as period expenses, absorption costing distributes fixed costs over all units produced, adding them to the unit cost of the product.

• Used for External Financial Reporting

Absorption costing is a generally accepted accounting practice (GAAP) and is required for external financial reporting under international accounting standards (IFRS) and generally accepted accounting principles (GAAP) in many countries. It ensures that the total production cost, including both variable and fixed costs, is reflected in the valuation of inventory and cost of goods sold (COGS).

• Inventory Valuation

Since both fixed and variable costs are included in the cost of production, absorption costing influences the valuation of inventories. Inventory on hand is valued at the full absorption cost, which includes all manufacturing costs incurred to produce the goods, affecting both the balance sheet and profit and loss account.

• Impact on Profitability

The treatment of fixed costs in absorption costing can affect profitability, particularly when production levels fluctuate. When production increases, fixed costs are spread over more units, which can reduce the per-unit cost and increase profitability. Conversely, low production levels may result in higher per-unit fixed costs, reducing profitability.

• Complex Cost Allocation

Absorption costing requires the allocation of fixed manufacturing overheads across all units produced. This allocation can be complex, as it often involves multiple cost drivers (e.g., labor hours, machine hours, or material costs) to determine how fixed costs should be assigned. This complexity may require detailed calculations and estimates.

• Long-Term Focus

Absorption costing is more suited for long-term decision-making as it provides a comprehensive view of the cost structure of a business. By allocating fixed costs to products, it helps in evaluating long-term pricing strategies, profitability, and capacity planning.

• Less Suitable for Short-Term Decision Making

Although absorption costing is useful for long-term financial analysis, it is less suitable for short-term decision-making, such as pricing decisions or make-or-buy analyses. Since fixed costs are absorbed into product costs, managers may overlook the impact of variable costs in short-term decision-making. Marginal costing is often preferred for such decisions.

Internal Decision Making	Used for pricing and decisions	Used for external reporting
Fixed Costs Allocation	Not allocated to products	Allocated to products

Budgetary Control is a process of monitoring and controlling the actual financial performance of an organization against the budgeted or planned financial performance. It involves comparing actual financial results with the budgeted results and taking corrective action if the actual results are not aligned with the planned results. The goal of budgetary control is to ensure that an organization’s financial resources are used effectively and efficiently to achieve its objectives.

Process of Budgetary Control:

• Budget Preparation:

The first step in budgetary control is the preparation of a comprehensive budget. This involves estimating the revenue and expenses for a particular period, typically a fiscal year, and allocating resources to various activities based on the organization’s priorities and goals.

• Budget Approval:

Once the budget is prepared, it needs to be approved by the relevant authorities in the organization. This ensures that the budget is aligned with the organization’s goals and objectives and is realistic and achievable.

• Implementation:

The approved budget is then implemented by the organization. This involves allocating resources to various activities and departments based on the budgeted amounts.

• Monitoring:

Once the budget is implemented, it is important to monitor actual financial performance against the budgeted performance. This involves tracking actual revenue and expenses and comparing them with the budgeted amounts.

• Variance Analysis:

Any differences between the actual financial results and the budgeted results are analyzed to determine the reasons for the variances. This analysis can help identify areas where corrective action is needed to bring the actual results in line with the budgeted results.

• Corrective Action:

Based on the variance analysis, corrective action is taken to address any issues that are causing the actual results to deviate from the budgeted results. This can involve adjusting resource allocation, reducing expenses, increasing revenue, or implementing other changes to bring the financial results back on track.

• Reporting:

Finally, the results of the budgetary control process are reported to relevant stakeholders in the organization. This includes financial reports that show the actual financial performance compared to the budgeted performance, as well as reports that detail any corrective actions taken and their impact on the organization’s financial performance.

Budgetary Control Types

There are several types of budgetary control that organizations use to ensure that their budgetary goals are met.

• Financial Budgetary Control:

This type of budgetary control focuses on the financial aspects of budgeting, such as revenue, expenses, cash flow, and profit. Financial budgetary control helps organizations to identify financial risks, make informed financial decisions, and ensure that financial targets are met.

• Performance Budgetary Control:

This type of budgetary control focuses on the performance aspects of budgeting, such as productivity, efficiency, and effectiveness. Performance budgetary control helps organizations to identify areas where performance can be improved, set performance targets, and monitor progress towards those targets.

• Zero-Based Budgetary Control:

This type of budgetary control involves starting each budgeting period from scratch, with no assumptions made about previous budgets. Zero-based budgeting requires that every expense must be justified, regardless of whether it was included in the previous budget.

• Flexible Budgetary Control:

This type of budgetary control allows for changes to be made to the budget as circumstances change. Flexible budgeting helps organizations to adapt to changes in the business environment, such as changes in customer demand, market conditions, or economic factors.

• Static Budgetary Control:

This type of budgetary control is based on fixed assumptions about revenue and expenses and does not allow for changes to be made to the budget. Static budgeting is useful when there is a high degree of certainty about revenue and expenses, but it can be less effective when there is a high degree of uncertainty.

• Incremental Budgetary Control:

This type of budgetary control involves making incremental changes to the budget each period, based on previous budgets. Incremental budgeting is useful when there is a high degree of certainty about revenue and expenses and when there is a need for stability in the budgeting process.

• Activity-Based Budgetary Control:

This type of budgetary control focuses on the activities that drive costs and revenue in an organization. Activity-based budgeting helps organizations to allocate resources to the most important activities, identify cost savings opportunities, and optimize revenue generation.

Budgetary Control Objectives
