$2,500,000
Cost
Percentage of Cost Directly
Traceable to Clients
Professional staff salaries ................................ $2,500,000 ..................................... 80%
Administrative support staff ............................. 300,000 ..................................... 60%
Travel ................................................................ 250,000 ..................................... 90%
Photocopying ................................................... 50,000 ..................................... 90%
Other operating costs ...................................... 100,000 ..................................... 50%
Total .............................................................. $3,200,000 .....................................
The firm’s partners desire to make a $640,000 profit for the firm and plan to add a percentage
markup on total cost to achieve that figure.
On March 10, JLR completed work on a project for Martin Manufacturing. The following costs
were incurred: professional staff salaries, $41,000; administrative support staff, $2,600; travel, $4,500;
photocopying, $500; and other operating costs, $1,400.
Required:
1. Determine JLR’s total traceable costs for the upcoming year and the firm’s total anticipated
overhead.
2. Calculate the predetermined overhead rate. The rate is based on total costs traceable to client jobs.
3. What percentage of cost will JLR add to each job to achieve its profit target?
4. Determine the total cost of the Martin Manufacturing project. How much would Martin be billed
for services performed?
5. Notice that only 50 percent of JLR’s other operating cost is directly traceable to specific client
projects. Cite several costs that would be included in this category and difficult to trace to clients.
6. Notice that 80 percent of the professional staff cost is directly traceable to specific client projects.
Cite several reasons that would explain why this figure isn’t 100 percent
