C251 Cost Accounting
fixed cost behavior per unit
FC per unit decreases as the activity level rises and increases as the activity level falls
variable cost behavior per unit
VC per unit remains constant
sunk cost
a cost that has already been incurred and that cannot be changed by any decision now or in the future
differential cost
a difference in costs between any two alternatives
differential revenue
a difference in sales between two alternatives
manufacturing overhead
all manufacturing cost except direct materials and direct labor (aka factory overhead, indirect manufacturing costs, or factory burden)
period costs
all the costs that are not product costs (selling/admin) expensed when incurred
dependent variable
amount of cost incurred during a period depends on the level of activity for the period
contribution margin
amount remaining from sales revenue after variable expenses have been deducted; COGS is considered variable
account analysis
an account is classified as either variable or fixed based on analyst's prior knowledge of how the cost behaves
discretionary fixed costs
annual decisions by management to spend on certain fixed costs items like advertising, research, public relations
cost object
anything for which cost data are desired
cost of goods sold
beginning inventory + purchases - ending inventory
independent variable
causes the variations in the cost
performance report
compares budgeted data to actual data in an effort to identify and learn from excellent performance and to identify and eliminate sources of poor performance
corporate social responsibility
concept whereby organizations consider the needs of all stakeholders when making decisions
managerial accounting
concerned with providing information to managers for use within the organization
financial accounting
concerned with reporting financial information to external parties
value chain
consists of major business functions that add value to products or services
mixed cost
contains both variable and fixed cost elements (aka semi-variable cost)
Describe cost classifications.
cost are classified differently according to need/purpose assigning costs to cost objects manufacturing companies for preparing financial statements predicting cost behavior making decisions
direct costs
cost that can be easily and conveniently traced to a specific cost object
indirect costs
cost that cannot be easily or conveniently traced to a specific cost object; considered a conversion cost
common costs
cost that is incurred to support a number of cost objects but cannot be traced to the individually
fixed cost
cost that remains constant in total regardless of changes in the level of activity
administrative costs
costs associated with general management of organization
indirect labor
costs that cannot be physically traced to a product
engineering approach
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, etc
budget
detailed plan for future that is expressed in formal quantitative terms
least squares regression method
diagnose cost behavior with a scattergraph plot if linear proceed uses all the data points uses regression line y=a+bx where y=total fixed costs and b=variable cost/unit computes the regression line that minimizes the sum of regression errors carried out by software
high-low regression method
diagnose cost behavior with a scattergraph plot if linear proceed variable cost=slope of line=rise/run rise over run = y2-y1/x2-x1 y2=cost at the highest level of activity y1=cost at the lowest level of activity x2=highest activity level x1=lowest activity level can also be expressed variable cost =change in cost/change in activity fixed cost element = total cost - variable cost element
conversion cost formula
direct labor + manufacturing overhead
prime cost formula
direct materials + direct labor
product cost formula
direct materials + direct labor + manufacturing overhead
planning
establish goals and how to achieve them
key difference b/t financial and managerial accounting
financial: outside, past activities, objective, verifiable, precision, GAAP/IFRS, external reports managerial: inside, affect future decisions, relevant, timely, not mandatory, need not follow GAAP, used for internal decision making
strategy
game plan
controlling
gathering feedback to ensure properly executed or modified when needed
net operating income
gross margin - selling - admin
product costs
include all costs involved in acquiring or making a product; attach to units of product; inventory; when sold COGS to match against revenue (aka inventoriable costs)
selling costs
include all costs that are incurred to secure customer orders and get finished product to customer (ex. advertising, shipping, commissions, and salary)
indirect materials
insignificant materials to end products (solder, glue, etc) included in manufacturing overhead
direct labor
labor costs that can be easily traced to individual units of product
lean production
management approach that organizes resources around the flow of business processes and that only produce units in response to customer orders
activity base
measure of whatever causes the incurrence of a variable cost (aka cost driver)
segment
part of an activity about which managers would like to cost, revenue or profit
opportunity cost
potential benefit that is given up when one alternative is selected over another
enterprise risk management
process used to identify risks and develop responses to them
contribution approach
provides managers with an income statement that distinguishes between fixed and variable costs
relevant range
range of activity within which the assumption that cost behavior is strictly linear is reasonably valid
cost behavior
refers to how a cost reacts to changes in the level of activity; as activity level rises and falls, a particular costs may rise, fall or remain constant
linearity assumption
relation b/t cost and activity can be represented by a straight line
curvilinear
relation b/t cost and activity is a curve
committed fixed costs
represents organizational investments with multiyear planning horizons that cannot be significantly reduced even for short periods of time without making fundamental changes
gross margin
sales - COGS
decision making
selecting course of action from competing alternatives
period cost formula
selling expenses + admin expenses
business process
series of steps that are followed in order to carry out some task
conversion costs
sum of direct labor and manufacturing overhead costs
prime costs
sum of direct material cost and direct labor cost
cost structure
the relative proportion of each type of cost
direct materials
those materials that become an integral part of the finished product and whose can be easily traced
fixed cost behavior in total
total FC is not affected by changes in the activity level within the relevant range
variable cost behavior in total
total VC increases/decreases in proportion to changes in activity
scattergraph plot
total maintenance cost = y plotted on vertical axis the activity = x plotted on horizontal axis if linear, make sense to perform high-low or least squares regression to separate mixed costs into its variable and fixed components if not linear, no sense for further analysis
the difference between a traditional income statement and a contribution format statement
traditional income statements are prepared primarily for external purposes; does not distinguish b/t fixed and variable costs contribution format statement breaksdown variable and fixed costs separately
variable cost
varies, in total, in direct proportion to changes in level of activity (constant if "per unit")
mixed cost formula
y=a+bx where y=total mixed costs a=total fixed cost b=variable cost per unit of activity (slope) x=the level of activity
