For use in litigating or defending a wide variety of costrelated legal issues:
– Federal antitrust cases - predatory pricing.
– Alleged contractual violations.
– Measurements of damages for lost sales/profits/etc. IES-Tomkins College 8 Common Types Of Cost Behavior FIXED COSTS: Costs that fundamentally are
not driven by changes in volume.
Y = Total Cost
Y = a, where a is the amount of fixed cost
Common examples of fixed costs - Depreciation,
Property taxes, Supervisor salaries

Common VARIABLE COSTS: Costs that change directly
and proportionately with the volume of activity.
Y = bX, where b is the slope of the line (the
increase in cost relating to the increase in volume)
and X is the measure of the volume of activity.
Common examples of variable costs - Direct
materials, Direct Labor, Sales Commissions

MIXED COSTS: Costs that contain both a
fixed and a variable component.
fixed Y = a + bX, Where a equals the fixed
component and bX is the variable
component. Common examples of mixed costs - Some
lease agreements, some utility costs, many

Learning curve costs - are costs that increase at a
decreasing rate with the volume of activity.
When graphed, learning curve costs slope upward
and to the right but not in a straight line; Instead
they curve downward.

SEMI-FIXED COSTS: Costs that
increase in steps or jumps. Also called set function costs Some argue that all fixed costs are step

usually based on historical cost observations and
analyses. If cost behavior characteristics are
