Answer: 101= 201= 303= 405=
Total units of products = 15+ 25+45+15 =100 units
total consumption value ( calculated separately below) = $21,000 + $10,000+ $2700+ $1050 = $34,750
1.Item 101
Cost per unit : $1400
No. Of units = 15
Annual consumption value = cost per unit × no of units
= 1400$ × 15 = $21,000
% of annual units sold = no of units of item 101/ total units × 100
=15/100×100=15%
% of annual consumption value = 21,000/34,750 ×100= 60.43%
2. Item 201
Cost per unit = $400, no of units =25
Annual consumption value (ACV) = 400×25= 10,000$
% of annual units sold = 25/100 ×100 = 25%
% of ACV= 10,000/34,750×100 = 28.77%
3. Item 303
Cost per unit=$60
No. Of units =45
Annual consumption value= $2700
% of annual units sold = 45/100×100= 45%
% of ACV = 2700/34750×100 = 7.76 %
4. Item 405
cost per unit= $70
no of units = 15
annual consumption value = 70 ×15 = $1050
% of ACV = 1050/34750 ×100 = 3.02%
% of annual units sold = 15 /100 ×100 = 15
% of annual consumption value = 1050/
thus, by the calculation shown above we can use the data to classify the items as per ABC classification.
ABC classification is used in business to identify the most important stocks and to keep a regular eye on them.
1. In the category A, we have products that are most important and valuable. It is the smallest category, but it takes up the highest consumption value in dollars.
2. In the B category, the products are higher in terms of no of units, but the cost of product is relatively low.
We can see this in item 201.
It makes up for around 25 % of the inventory but it costs only 28% of the total consumption value.
Items in category B are moderately important.
3. In category C, we observe that these products make up for the highest inventory, but in terms of money they are very cheap.
This can be observed in item 303 and item 405.
Together, they constitute about 60% of the inventory but their value in terms of consumption is only 10% together.
Items in category C are relatively unimportant.
