Key Terms: Chapter Eighteen

break-even point

The level of activity where revenues equal total expenses, producing a zero net income; also the point where the contribution margin is said to cover fixed costs

committed fixed cost

Costs that arise from an organization's commitment to engage in operations; unavoidable elements like depreciation, rent, insurance, property taxes

contribution margin

Revenues minus all variable expenses, whether related to production or selling and administration (not to be confused with gross profit)

cost-volume-profit analysis

(CVP) Analysis focusing on the interplay of pricing, volume, variable and fixed costs, and product mix

discretionary fixed cost

Fixed cost resulting from yearly spending decisions; proper planning can result in avoidance of these costs as necessary (e.g., advertising and training)

economies of scale

Efficiencies associated with increases in volume

fixed cost

A total cost that is the same regardless of volume; total cost is constant and per unit cost decreases with volume increases

high-low method

A simple means for separating costs into fixed and variable components, based upon the difference between costs at the highest and lowest observed levels of activity

method of least squares

A complex means for separating costs into fixed and variable components, based upon minimizing the variances between all observations and the resulting assumed cost function

mixed costs

A cost that has both fixed and variable components

relevant range

The level of activity for which assumptions underlying CVP are expected to hold true

scattergraph

A simplistic mapping of observed data points, where a line is "visually" drawn to represent the estimated cost function

step cost

A cost function that is fixed over a range, and then increases by a measured step to a new level at the next higher increment of activity

target income

A level of income that is to be obtained; CVP projects activity levels necessary to achieve this benchmark

variable cost

A per unit cost that is the same regardless of volume; total variable cost increases with volume increases
