2. 14 - 2 Introduction The Wrap Rate technique is a method used to allocate profit and other overhead costs to actual labor costs.
Total Cost equals
Direct Labor Cost
plus Overhead Cost
plus Other Costs
3. 14 - 3 Direct Labor Many of our cost estimating relationships use labor hours as a parameter, or predict cost in terms of labor hours.
There are two major categories of direct labor:
Engineering
Activities associated with research, design, and development or preparation of products and procedures.
Manufacturing
This is the hands-on effort to produce a product.
4. 14 - 4 Wrap Rates Once we have determined the labor hours required to produce an item, either by performing an engineering buildup or by applying a cost estimating relationship, we need a means of converting those hours to dollars.
A fully-burdened labor rate is a rate which includes all the contractor costs necessary to convert an estimate of contractor hours to contractor dollars.
The wrap rate will typically include the direct labor wage rate, overhead costs, and other costs.
5. 14 - 5 Wage Rates Four general factors impact the labor wage rate:
Variations in Geographical Locations
Supply and Demand of Work Available
Contractor Labor Force Variations
Supply and Demand of Workers
Variations in Skills
High skills vs. low skills
Variations with Time
Inflation
COLAs
6. 14 - 6 Overhead Rates Also known as Indirect Cost or Burden.
These costs are not directly identifiable with a specific cost objective.
There are two distinct types of overhead costs:
Those that are so general in nature they cannot be assigned to a specific cost objective
Plant and equipment maintenance
Those that are so inconsequential that the cost of accounting for them exceed the benefits derived from doing so.
Consumables such as washers, sandpaper, lubricants.
7. 14 - 7 Overhead Rates Most firms collect indirect costs in aggregate cost accounts called overhead pools such as
Manufacturing and Engineering Indirect Pools
General and Administrative Pools
Service Center Pools
8. 14 - 8 Overhead Rates Most common Indirect Cost Pools:
Material Overhead: Costs related to transportation, acquisition, inspection and handling of materials.
Manufacturing Overhead: Indirect labor costs including supervision, inspection and maintenance.
Engineering Overhead: Costs of directing and supporting the activities of the Engineering Department.
General and Administrative: The costs of the companys general and executive offices.
9. 14 - 9 Overhead Recovery Bases In order to recover overhead costs it is necessary to allocate the indirect costs to the cost objective. This allocation results in charging the cost objective a share of the total indirect costs.
Bases often include:
Direct Labor Hours
Direct Labor Dollars
Number of Production Units
Machine Hours
10. 14 - 10 Other Costs The last piece needed to build a fully burdened wrap rate is Other Costs.
Other Costs typically include
Profit (or fee)
Cost of Money
General and Administrative
