Introduction: What Is the ABC Method & Why It Matters
The ABC Method, short for Activity-Based Costing, is a modern accounting approach used to allocate overhead and indirect costs more accurately to products and services. Unlike traditional costing methods that rely on a single cost driver, ABC uses multiple activities to identify where resources are consumed.
This method is especially important for business owners, accountants, CFOs, cost analysts, and financial planners aiming to improve cost-efficiency, product pricing, and profitability.
Understanding the ABC Method in accounting is crucial for strategic decision-making in manufacturing, service-based businesses, and even in GST or income tax compliance in India.
Definition of ABC Method
ABC Method (Activity-Based Costing) is an accounting technique that assigns overhead and indirect costs to products or services based on the activities they require.
Detailed Explanation of the ABC Method
🔹 1. Types of Costs in ABC
ABC primarily categorizes costs into:
-
Direct Costs: Direct materials or labor, easily traceable.
-
Indirect Costs: Overhead expenses (electricity, rent, administration) allocated through activities.
🔹 2. How the ABC Method Works
Here’s a step-by-step breakdown of how ABC costing functions:
| Step | Activity | Purpose |
|---|---|---|
| 1 | Identify key activities in the business process | e.g., packaging, machine setup, inspection |
| 2 | Assign costs to each activity | Based on resources consumed (cost pools) |
| 3 | Identify cost drivers | Factors like machine hours, labor hours |
| 4 | Allocate costs to products/services | Based on cost driver consumption |
🔹 3. Why ABC Method Is Important
-
Improves accuracy of product costing
-
Aids in identifying cost-saving opportunities
-
Helps in profitability analysis
-
Enhances budgeting and pricing strategies
🔹 4. ABC Costing Formula
While there’s no single formula, the cost allocation in ABC is generally done as:
Cost per Activity = Total Cost of Activity ÷ Total Cost Driver Units
Then,
Product Cost = Cost Driver Rate × Number of Driver Units Used by Product
📘 Accounting Illustration with Journal Entry
Scenario:
A company incurs ₹60,000 in machine setup costs and ₹40,000 in inspection costs. Two products, A and B, use 20 and 10 machine setups respectively.
Step 1: Calculate Cost Driver Rate
Machine Setup Cost Driver Rate = ₹60,000 / (20 + 10) = ₹2,000 per setup
Product A uses 20 setups = ₹2,000 × 20 = ₹40,000
Product B uses 10 setups = ₹2,000 × 10 = ₹20,000

📊 Visual Aid: Traditional vs ABC Method Comparison
| Feature | Traditional Costing | ABC Costing |
|---|---|---|
| Basis of Allocation | Single cost driver | Multiple activities |
| Accuracy | Less | High |
| Best Suited For | Homogeneous products | Complex, multi-product firms |
| Identifies Non-Value Add | No | Yes |
🏛️ Tax Implications in India
While the ABC Method is not directly mandated under Indian tax laws, it plays a vital role in:
-
Cost Audit Reporting under Companies Act, 2013
-
Product-wise profitability which helps in GST valuation
-
Assisting companies in Transfer Pricing Analysis for related party transactions
-
Used in internal costing systems for ITR documentation and reporting compliance
📈 Real-Life Example
Example:
A manufacturing firm produces Product X and Product Y. Instead of allocating ₹1 lakh in electricity costs equally, they apply ABC.
-
Product X uses 60% of machine time
-
Product Y uses 40%
Using ABC:
-
Product X is allocated ₹60,000
-
Product Y is allocated ₹40,000
This results in more realistic product pricing and higher profit accuracy.
