1.5 Cost Concepts

There are some important cost concepts that we must be aware of:

1.5.1 Cost Unit

Cost unit is defined by the ICMA as “a quantitative unit of product or service in relation to which
costs are ascertained”. A cost unit is a device used for the purpose of splitting total cost into smaller
sub-divisions attributable to products or service. A cost unit simply stated is a unit of fi nished
product, service of these in relation to which cost is ascertained and expressed. The following are
some of the examples of cost units selected from different industries or organisation:

1.5.2 Cost Centre

A cost centre refers to a part of a factory for which costs are accumulated separately. In order
to facilitate charging of costs to cost units, it is necessary to divide the factory or industry into
various parts which can be used to accumulate costs for subsequent distribution. Each such part
of a factory or industry is known as cost centre.

Cost centre facilitates fixation of responsibility for every officer-in-charge of part of
department or section. Hence cost centre is also known as responsibility centre.
Cost centre has been defined by ICMA as “a location, person or item of equipment or group of

these in respect of which costs may be ascertained and related to cost units”.
