Advantages of ABC Analysis,
For example we consider a company manufacturing, Product A & Product B.
Product A,
Production volume: 19,000 units
Unit cost of direct materials and labor: ₹45
Product B,
Production volume: 11,000 units
Unit cost of direct materials and labor: ₹55
Manufacturing Overhead :
Total manufacturing overhead costs: ₹30000
Factory supervisor salaries: ₹80000
Further, as product B is more complex to manufacture and needs more attention, the company decides the salaries of the supervisor should be allocated with ₹30,000 to product A and ₹50,000 to product B.
Now if we use Full-costing allocation method, we get
Total cost of production for Product A: ₹55
Total cost of production for Product A: ₹65
Using ABC method,
Product A,
Allocation of factory supervisors: ₹30000/19000 = ₹1.6
Manufacturing overhead to be applied to total production volume: ₹2,20,000/30,000 = ₹7.3
Unit cost of manufacturing overhead: ₹1.6 + ₹7.3 = ₹8.9
Total unit cost of production: ₹45 + ₹8.9 = ₹53.9
Product B,
Allocation of factory supervisors: ₹50,000 /11,000 = ₹4.5
Manufacturing overhead to be applied to total production volume: ₹2,20,000/30,000 = ₹7.3
Unit cost of manufacturing overhead: ₹7.3 + ₹4.5 = ₹11.8
Total unit cost of production: ₹55 + ₹11.8 = ₹66.8
This proves that, ABC analysis shows that the total cost of production for product A is actually ₹53.9 per unit, not ₹55 as originally calculated. Product B costs ₹66.8 instead of the previous ₹65.
These variations in prices of production have implications for profit forecasting, production planning and budget for marketing campaigns.
Instances where ABC Analysis will create complications,
When we take the above example with only one product or overheads are relatively small or no allocation done on supervisory salaries based on product's complexity, there is no need of ABC Analysis.
When the product range is large, cost accumulation and data collection are complex and requires an advanced cost recording system and properly trained staffs.
When it is difficult to assign cost to different activities.
