1 CEF values are based on the preliminary proposed levels in the RFI and are based on the DOE test procedure at 10 CFR 430, subpart B, appendix D2.

2 Depreciation on the conversion capital expenditure should NOT be included in the incremental overhead. 

3 Incremental costs per unit should be reported relative to the baseline unit’s cost. The baseline unit complies with the current federal standard for residential clothes dryers

Direct material – Costs of raw materials including scrap that can be traced to final or end products. Direct material costs do not include indirect material costs which are attributed to supplies that may 

be used in the production process but are not assigned to final products (e.g., lubricating oil for production machinery).

Direct labor – The earnings of workers who assemble parts into a finished good for operate machines in the production process. Direct labor includes the fringe benefits of direct laborers such as group 

health care, as well as overtime pay. Direct labor does not include indirect labor which is defined as the earnings of employees who do not work directly in assembling a product, such as supervisors, 

janitors, stockroom personnel, inspectors, and forklift operators.

Overhead – Factory overhead excluding depreciation. Factory overhead includes indirect labor, downtime, set-up costs, indirect material, expendable tools, maintenance, property taxes, insurance on 

assets, and utility costs. Factory overhead does not include selling, general, and administrative costs (SG&A); research and development (R&D); interest; or profit (accounted for by DOE separately).

Full Production Cost = Direct Material + Direct Labor + Overhead (factory) + Depreciation

Full Cost of Product = Full Production Cost + Non-production Costs (SG&A, R&D, interest, and profit)
