Joint cost
allocation means to allocate the cost for those products which require the same
kind of raw material and part of a same manufacturing process. But at the end
of the result two or more than two final products we have form this
manufacturing activity. Each product
require the almost same material but the cost allocations to them is different
during the manufacturing activities.
There
are many different methods the product based
organizations using in their manufacturing processes. The mostly known
are Physical unit method in which each portion allocates the costs as per the
activity weight. Sales- Value at Split-Off method in which the cost allocations
to the activities over the sales of the
products. The other two methods are estimated net realizable value method, and
Constant gross-margin percentage NRV method in which a set or same percentage
of margin issued to products and subtract the separable costs to arrive at the
joint cost amount.
The further short explanations for these joint cost
allocation methods are as follows:
Physical Unit method:
The
Physical Unit method of allocation joint costing is use for separable products
and costing is based on the weight allocated to each portion of the production.
The formula for the Physical Unit method is as follows:
Sales-Value at
Split-Off method:
Sales-Value
at split-off method is based on separate products relative proportion of total
sales value ultimately attributable to the period of production and the
resultant is multiplied by total joint cost.
Estimated net
realizable value method:
According
to this joint cost allocation method there is a variation of the relative sales
value method. The difference is total under the NRV method all costs which are
already separate necessary to make the product salable are subtracted before
the allocation is made and then multiplied by joint cost.
Constant gross-margin
percentage NRV method:
According
to this method same gross margin percentage for all of the products. Then we
find out the overall gross margin percentage and subtract the appropriate gross
margin form the final sales value of each product to calculate total coasts for
the product and at last to subtract the separate costs to arrive at the joint
cost amount.
That’s are the some of the Joint Cost allocation methods and
their short explanations during writing over this topic I tried my best to make it understandable for my readers and tried my best to write the easy key words and sentences to make all the key terms and wording for them. The whole topic and and relevant formulas are helpful to the general readers, professional and
students.
“The topic is taken from the Sub Unit No: 03 Cost
Management terminology and concepts from the book of Gleim 15th
edition which is very helpful to the CMA-USA Certification Seekers.”
