1. Cost Behavior:Analysis and Usej.paquette/Accounting 230/Bellevue Community College
2. Learning Objectives Define/discuss the concept of Cost Behavior
True vs. Step Variable cost
Understand relevant range
Use scattergraph plot to diagnose cost behavior
Use high-low method to analyze mixed costs
Using contribution format, prepare an IS
3. Types of Cost Behavior Patterns
4. The Activity Base
5. True Variable Cost Example Your total long distance telephone bill is based on how many minutes you talk.
6. Variable Cost Per Unit Example The cost per minute talked is constant. For example, 10 cents per minute.
7. Step-Variable Costs
8. Step-Variable Costs
9. The Linearity Assumption and the Relevant Range
10. Total Fixed Cost Example Your monthly basic telephone bill is probably fixed and does not change when you make more local calls.
11. Fixed Cost Per Unit Example The fixed cost per local call decreases as more local calls are made.
12. Cost Behavior
13. Types of Fixed Costs
14. Example: Office space is available at a rental rate of $30,000 per year in increments of 1,000 square feet. As the business grows more space is rented, increasing the total cost.
What is the relevant range? Fixed Costs and Relevant Range
15. Fixed Costs and Relevant Range
16. Fixed Costs and Relevant Range
17. Quick Check ? Which of the following statements about cost behavior are true?
Fixed costs per unit vary with the level of activity.
Variable costs per unit are constant within the relevant range.
Total fixed costs are constant within the relevant range.
Total variable costs are constant within the relevant range.

26. WiseCo recorded the following production activity and maintenance costs for two months:
Using these two levels of activity, compute:
the variable cost per unit;
the fixed cost; and then
express the costs in equation form Y = a + bX. The High-Low Method
29. Does this work for the low volume level, too? Test it!
