JLR Enterprises provides consulting services throughout California and uses a job-order costing system to accumulate the cost of client projects. Traceable costs are charged directly to individual clients; in contrast, other costs incurred by JLR, but not identifiable with specific clients, are charged to jobs by using a predetermined overhead application rate. Clients are billed for directly chargeable costs, overhead, and a markup.

JLR’s director of cost management, Brent Dean, anticipates the following costs for the upcoming year:

Cost , Percentage of Cost, Directly Traceable to Client,

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.
