S4.11 The Cost Tables

S4.11.1 All costs in the Cost Report come from the standardized Cost Tables. These tables have been

compiled to represent the cost of parts and processes that a manufacturing company could be expected to pay for manufacturing a vehicle at 1000 units per year. Generally, the tabulated value represents ½ of the Manufacturer’s Suggested Retail Price (MSRP) for finished parts. Raw materials, commodities and fasteners also intended to represent the production volume of a company rather than the purchase price of the University teams.

S4.11.2 Requests to alter the cost of goods in the tables because of changing world markets or individual team purchase price will not be approved. The tables are intended to provide a fair, unchanging (within a given competition year) cost for parts and to reduce regional variations in price that may help or hurt certain teams. All teams must use the costs given in the tables. If a team wishes to use any parts, processes or materials not included in the tables an “Add Item Request” must be submitted as per Section C3.13.

S4.11.3 The tables represent cost based on specific parameters. For example the cost of steel is given per unit of volume (or mass). Likewise, engine costs are listed by displacement and specific power output.

S4.11.4 The following Cost Tables are used

· Materials

· Processes

· Process Multipliers

· Fasteners

· Tooling

S4.11.5 In general, most items have a cost expressed as a function of one parameter. In cases where more than one parameter is necessary additional categories are listed. For example the power output of the engine has three Categories and for each Category a different expression calculates the cost as a

function of the engine displacement, which is the Parameter. The Unit would be cubic centimeters in this case.

S4.11.6 Process Multipliers are used to modify the standard costs of different operations to account for material and geometric differences in the part. For every process included in the Cost Report the list of process multipliers must be checked to determine if any apply, and if they do their effect on the cost must be included.

S4.11.7 When adding items from tables to the BOM the comments section should be reviewed thoroughly to understand what is included in the table entry. For example is the spring included in the damper cost? Do the spark plugs come with the engine or are they a separate line item? In cases where the explanation is not clear please contact the Rules Committee for clarification.

S4.12 Cost Models & Costing Methodology

The cost models are the underlying methodology and equations that relate the final cost of a part or

process to the different operations and goods used in that part. The detailed explanation of the Cost Models and Costing Methodology is included in Appendix C-1 and should be referenced for understanding the use of the Cost Tables.
