direct cost
a cost that can be easily and conveniently traced to a specified cost object (can be easily traced)
indirect cost
a cost that cannot be easily and conveniently traced to a specified cost object (cannot be easily traced)
common cost
a cost that is incurred to support a number of cost objects but cannot be traced to them individually. (a common cost is a type of indirect cost)
Manufacturing companies such as (Texas Instruments, Ford, and DuPont) separate their costs into 2 broad categories:
1. manufacturing costs
2. nonmanufacturing costs
Most manufacturing companies further separate their manufacturing costs into 2 direct cost categories, (_____ & _____) AND one indirect cost category (_______)
1. direct materials
2. direct labor
3. manufacturing overhead
raw materials & they may include (1._____ & 2. _____)
materials that go into the final product
1. direct materials
2. indirect materials
direct materials
those materials that become an integral part of the finished product and whose costs can be conveniently traced to the finished product
2 examples of direct materials
1. seats that Airbus purchases from subcontractors ton install in its commercial aircraft
2. electronic components that Apple uses in its iPhones
direct labor
consists of labor costs that can be easily (physically & conveniently) traced to individual units of products
direct labor is sometimes called ________
touch labor b/c direct labor workers typically touch the product while it is being made
indirect labor
labor costs that cannot be physically traced to particular products, or that can be traced only at a great cost & inconvenience
manufacturing overhead
3rd manufacturing cost category, includes all manufacturing costs except direct materials and direct labor
nonmanufacturing costs are often divided into 2 categories:
1. selling costs
2. administrative costs
selling costs
includes all costs that are incurred to secure customer orders and get the finished product to the customer
administrative costs
includes all costs associated w/ general management of an organization rather than with manufacturing or selling
matching principle
based on the accrual concept that costs incurred to generate a particular revenue should be recognized as expenses in the same period that the revenue is recognized
product costs
include all costs involved in acquiring or making a product
inventoriable costs
because product costs are initially assigned to inventories
period costs
are all the costs that are not product costs
All __________ and ______________ expenses are treated as period costs
1. selling
2. administrative
product cost =
direct materials + direct labor + manufacturing overhead
period cost =
selling expenses + administrative expenses
conversion cost =
direct labor + manufacturing overhead
prime cost =
direct materials + direct labor
variable cost
varies, in total, in direct proportion to changes in the level of activity
variable cost is constant if __________________
expressed on a per unit basis
fixed cost
cost that remains constant, in total, regardless of changes in the level of activity
relevant range
is the range of activity within which the assumption that cost behavior is strictly linear is reasonably valid
mixed cost
contains both variable and fixed cost elements (aka semivariable costs)
Y = a + bX
Y = total mixed cost
a = total fixed cost
b = variable cost per unit of activity
X = activity level
account analysis
an account is classified as either variable or fixed based on analyst’s prior knowledge of how the cost in the account behaves
engineering approach
to cost analysis involves a detailed analysis of what cost behavior should be, based on an industrial engineer’s evaluation of the production methods to be used, the material specifications, labor requirements, equipment usage, production efficiency, power consumption, and so on
dependent variable
cost (the amount of cost incurred during a period depends on the level of activity for the period) — total maintenance cost–Y
independent variable
activity (causes variations in the cost) –activity —X
cost behavior is considered _________ whenever a straight line is a reasonable approximation for the relation b/w cost and activity
the fixed and variable cost elements of a mixed cost can be estimated using the ______________ method
high-low method / least-squares regression method
variable cost =
(slope of line) =
(cost at high activity level – cost at the low activity level) /
(high activity level – low activity level)
OR change in cost / change in activity
fixed cost element =
total cost – variable cost element
least-squares regression method
uses all of the data to separate a mixed cost into its fixed and variable components
cost of goods sold =
beginning ending
merchandise + purchases — merchandise
inventory inventory
contribution margin
is the amount remaining from sales revenues after variable expenses have been deducted (this amount contributes toward covering fixed expenses and then toward profits for the period)
differential cost
a diff. in costs b/w any 2 alternatives (aka “incremental cost”)
differential revenue
a diff. in revenues (usually just sales) b/w any 2 alternatives
marginal revenue
the revenue that can be obtained from selling one or more unit of product
opportunity cost
the potential benefit that is given up when one alternative is selected over another
sunk cost
cost that has already been incurred and that cannot be changed by any decision made now or in the future (**should always be ignored)
A particular cost is either direct or indirect, regardless of the cost object (true/false?)
an individual cost may be indirect to one cost object and direct to another (true/ false?)
a regional sales manager’s salary would be a direct cost of the regional office in which the sales manager works (true/ false?)
a direct cost can be easily and conveniently traced to a specific cost object (true/false)
a direct cost is sometimes referred to as a common cost (true/false)
marginal cost
the cost added by producing one extra item of a product
direct materials & direct labor are both:
manufacturing costs
manufacturing costs can be divided into 3 categories:
1. direct materials
