Definition of relevant costing

relevant costing

a process that compares, to the extent possible
and practical, the incremental revenues and incremental costs of alternative decisions

Absorption costing

A method of costing in which all fixed and variable production costs are charged to products or services using an allocation base.

Activity-based costing

A method of costing that uses cost pools to accumulate the cost of significant business activities and then assigns the costs from the cost pools to products or services based on cost drivers.

Job costing

A method of accounting that accumulates the costs of a product/service that is produced either
customized to meet a customer’s specification or in a batch of identical product/services.

Lifecycle costing

An approach to costing that estimates and accumulates the costs of a product/service over
its entire lifecycle, i.e. from inception to abandonment.

Process costing

A method of costing for continuous manufacture in which costs for an accounting compared are compared with production for the same period to determine a cost per unit produced.

Relevant cost

The cost that is relevant to a particular decision – future, incremental cash flows.

Relevant range

The upper and lower levels of activity within which the business expects to be operating within the short-term planning horizon (the budget period).

Target costing

A method of costing that is concerned with managing whole-of-life costs of a product/service during the product design phase – the difference between target price (to achieve market share) and the target profit margin.

Variable costing

A method of costing in which only variable production costs are treated as product costs and in which all fixed (production and non-production) costs are treated as period costs.

activity based costing (ABC)

A relatively new method advocated for the
allocation of indirect costs. The key idea is to classify indirect costs,
many of which are fixed in amount for a period of time, into separate
activities and to develop a measure for each activity called a cost driver.
The products or other functions in the business that benefit from the
activity are allocated shares of the total indirect cost for the period based
on their usage as measured by the cost driver.

absorption costing

a cost accumulation and reporting
method that treats the costs of all manufacturing components
(direct material, direct labor, variable overhead, and
fixed overhead) as inventoriable or product costs; it is the
traditional approach to product costing; it must be used for
external financial statements and tax returns

activity-based costing (ABC)

a process using multiple cost drivers to predict and allocate costs to products and services;
an accounting system collecting financial and operational
data on the basis of the underlying nature and extent
of business activities; an accounting information and
costing system that identifies the various activities performed
in an organization, collects costs on the basis of
the underlying nature and extent of those activities, and
assigns costs to products and services based on consumption
of those activities by the products and services

attribute-based costing (ABC II)

an extension of activitybased costing using cost-benefit analysis (based on increased customer utility) to choose the product attribute
enhancements that the company wants to integrate into a product

backflush costing

a streamlined cost accounting method that speeds up, simplifies, and reduces accounting effort in an environment that minimizes inventory balances, requires
few allocations, uses standard costs, and has minimal variances
from standard

direct costing

see variable costing

FIFO method (of process costing)

the method of cost assignment that computes an average cost per equivalent
unit of production for the current period; keeps beginning
inventory units and costs separate from current period production
and costs

full costing

see absorption costing

hybrid costing system

a costing system combining characteristics
of both job order and process costing systems

job order costing system

a system of product costing used
by an entity that provides limited quantities of products or
services unique to a customer’s needs; focus of recordkeeping
is on individual jobs

life cycle costing

the accumulation of costs for activities that
occur over the entire life cycle of a product from inception
to abandonment by the manufacturer and consumer

modified FIFO method (of process costing)

the method of cost assignment that uses FIFO to compute a cost per
equivalent unit but, in transferring units from a department,
the costs of the beginning inventory units and the
units started and completed are combined and averaged

process costing system

a method of accumulating and assigning costs to units of production in companies producing large quantities of homogeneous products;
it accumulates costs by cost component in each production department and assigns costs to units using equivalent units of production

relevant cost

a cost that is logically associated with a specific problem or decision

relevant range

the specified range of activity over which a
variable cost per unit remains constant or a fixed cost remains
fixed in total; it is generally assumed to be the normal
operating range of the organization

strict FIFO method (of process costing)

the method of cost assignment that uses FIFO to compute a cost per equivalent unit and, in transferring units from a department, keeps the
cost of the beginning units separate from the cost of the
units started and completed during the current period

target costing

a method of determining what the cost of a
product should be based on the product’s estimated selling
price less the desired profit

variable costing

a cost accumulation and reporting method
that includes only variable production costs (direct material,
direct labor, and variable overhead) as inventoriable
or product costs; it treats fixed overhead as a period cost;
is not acceptable for external reporting and tax returns

weighted average method (of process costing)

the method of cost assignment that computes an average cost per
equivalent unit of production for all units completed during
the current period; it combines beginning inventory units
and costs with current production and costs, respectively,
to compute the average

Absorption costing

A methodology under which all manufacturing costs are assigned
to products, while all non-manufacturing costs are expensed in the current period.

Activity-based costing (ABC)

A cost allocation system that compiles costs and assigns
them to activities based on relevant activity drivers. The cost of these activities can
then be charged to products or customers to arrive at a much more relevant allocation
of costs than was previously the case.

Direct costing

A costing methodology that only assigns direct labor and material costs
to a product, and which does not include any allocated indirect costs (which are all
charged off to the current period).

First in, first-out costing method (FIFO)

A process costing methodology that assigns the earliest
cost of production and materials to those units being sold, while the latest costs
of production and materials are assigned to those units still retained in inventory.

Kaizen costing

The process of continual cost reduction that occurs after a product
design has been completed and is now in production. Cost reduction techniques can
include working with suppliers to reduce the costs in their processes, implementing
less costly re-designs of the product, or reducing waste costs.

Process costing

A costing methodology that arrives at an individual product cost through the calculation of average costs for large quantities of identical products.
