CTC 475 Job Quotes & Present Economy Problems
Objectives • Know how to give job quotes • Understand how to identify a present economy problem • Know how to work present economy problems
Job Quotes • Rate per Direct Labor Hour • Percentage of Direct Labor Cost • Percentage of Prime (Labor+Matl) Cost
Job Quotes Must Prorate: • Labor • Material • Overhead
Job Quotes Example • Determine quote using all 3 methods for a job that will need: • 40 hours of direct labor and • $850 of direct material
Method 1: Rate per Direct Labor Hour • Distribute overhead by labor hours: • Rate = Ovhd/Labor Hrs. = $360,000/48,000 • =$7.50 per direct labor hour
Method 2: Rate per Direct Labor Cost • Distribute overhead by labor cost: • Rate = Ovhd/Labor Cost = $360,000/$480,000 • =75%
Methods 1 & 2 • Yield same result if the rate per direct labor hour is average labor rate
Method 3: % of Prime Cost • Distribute overhead by prime cost: • Rate = Ovhd / Direct Labor + Direct Material Cost = $360,000/($480,000+$600,000) • =33.3%
Method 3 • Gives different answer than method 1/2
Different companies use different methods • Most common is method 1 • Consulting firm I worked at– similar to method 2
Cost Centers • Average overhead rates may not work if you make products that are very different • Can split costs among departments • i.e. architect dept., engineering dept.
Job Quotes (w/ profit) • Our previous examples did not include profit • Profit must be added • Assume a job requires $500 worth of material and 30 direct labor hours (@ $6/hr). Using a $3/hour overhead rate and a profit margin of 20%, determine the job quote
Time Value of Money • Most of this course is based on the fundamental concept that money has a time value • Must take this concept into account since projects have different cash flow patterns at different times
Present Economy Problems • Time is not a significant factor
Conditions: • No investment of capital • Long-term costs are the same for all alternatives • Alternatives have identical results
Example-Present Economy • A metal part can be machined on an engine lathe (one at a time) or turret lathe (many at a time) Material costs are the same regardless of the machine used. • Parts are produced in batches according to the customer’s order • Based on the following cost data, what machine should be used for order sizes of 25, 100 and 500 units?
Summary • Turret lathe costs less per unit but has a high setup cost • Engine lathe costs more per unit but has no setup costs When do I use which machine?
Comparison Costs Switchover occurs somewhere between 25 and 100 units (n=1 setup)
Determine breakeven point-Math • 2.10x+48=3.45x • x=35 units (assumes N=1 setup)
