Terminal Learning ObjectiveTerminal Learning Objective• Task: Determine the fixed and variable components
of a mixed cost using the High-Low method• Condition: You are a cost advisor technician with
access to all regulations/course handouts, and awareness of Operational Environment (OE)/Contemporary Operational Environment (COE) variables and actors.
• Standard: with at least 80% accuracy• Calculate fixed and variable cost components
from mixed cost data• Describe High-low method

Need for High-Low MethodNeed for High-Low Method
• Fixed and variable components of cost are not always identifiable
• This is especially true in service activities• Sometimes costs aren’t strictly fixed and
variable but mixed or semi-variable• The High-Low Method permits further analysis
by finding an approximate value for variable and fixed costs

High-Low AssumptionsHigh-Low Assumptions
• The relationship between the cost at the highest level of output and the cost at the lowest level of output is linear
• This linear relationship reasonably represents the relationship between costs at other levels of output
• The change in cost from the highest level to the lowest level is due to the change in units from the highest level to the lowest:
• Change in cost / change in units = VC/unit

High-Low CalculationHigh-Low Calculation
• Step 1: Calculate Variable Cost $/unit: • Change in cost / change in units or:
$ at high output – $ at low output # Units at high output – # Units at low output
• Step 2 Calculate Fixed Cost : • Total Cost – Variable Cost or:
$ high output – VC $/unit * # Units high output

• Step 3: Develop the cost expression for total cost:
Total cost = VC $/unit * # units + Fixed cost
• This equation can be used for:•Planning for various levels of output•Break even analysis (Day 9)

High-Low ExampleHigh-Low Example
• The manager of the purchasing department sees that total costs increase as Purchase Orders increase
• However, he knows that the cost is not strictly variable
• He would like to segregate the variable component of the cost from the fixed cost
