Variable and Fixed Costs, Cost Formula, High-Low Method
Li Ming Yuan and Tiffany Shaden are the department heads for the accounting department and
human resources department, respectively, at a large textile firm in the southern United States.
They have just returned from an executive meeting at which the necessity of cutting costs and gaining efficiency has been stressed. After talking with Tiffany and some of her staff members, as well
as his own staff members, Li Ming discovered that there were a number of costs associated with
the claims processing activity. These costs included the salaries of the two paralegals who worked
full time on claims processing, the salary of the accountant who cut the checks, the cost of claims
forms, checks, envelopes, and postage, and
processing. Some of the paralegals’ time appears to vary with the routine processing of uncontested
claims, but considerable time also appears to be spent on the claims that have incomplete documentation or are contested. The accountant’s time appears to vary with the number of claims processed.
Li Ming was able to separate the costs of processing claims from the costs of running the departments of accounting and human resources. He gathered the data on claims
and the number of claims processed per month for the past 6 months. These data are as follows:
Required:
1. Classify the claims processing costs that Li Ming identified as variable and fixed.
2. What is the independent variable? The dependent variable?
3. Use the high-low method to find the fixed cost per month and the variable rate. What is
the cost formula?
4. CONCEPTUAL CONNECTION Suppose that an outside company bids on the claims
processing business. The bid price is $4.60 per claim. If Tiffany expects 75,600 claims next
year, should she outsource the claims processing or continue to do it in-house?
