### APPENDIX 6-A. DETAILED DATA FOR PRODUCT COST MARKUPS

6-A.1 MARKUPS VALIDATION

This appendix provides further details on the markups validation presented in chapter 6, Markups to Determine Product Cost. As part of its market data collection, DOE assembled a data base with retail Internet prices for a large number of clothes dryer models at baseline efficiency. Additionally, DOE used detailed sales data from NPD Group, a market research firm, to estimate room air conditioner retail prices at baseline efficiency for three of the product classes. a



### For each model, DOE divided the retail price by the estimated manufacturer cost for the appropriately-sized clothes dryer or room air conditioner (estimated as described in chapter 5) to derive an implicit markup. This markup would include the manufacturer markup and the retail markup. To be comparable with the overall markups shown in Table 6.6.1, DOE added U.S.­ average sales tax values for each product. Table 6-A.1.1 and Table 6-A.1.2 provide details of the baseline markup validation for select clothes dryer and room air conditioner product classes, as

defined in the Framework Document. 1 

### Room air conditioner product classes are defined by louvered or non-louvered sides, and by Btu per hour cooling capacity. Clothes dryer product classes are defined by drum capacity. Because the manufacturer production costs differ by product class, a separate markup is estimated for each product class.

In chapter 6, Markups to Determine Product Cost, DOE estimates an overall baseline markup of 1.95 for both room air conditioners and clothes dryers. As illustrated by Table 6-A.1.1 and Table 6-A.1.2, DOE’s markup validation of detailed sales data arrives at similar markup estimates for most product class, ranging between 1.71 and 2.40.

Some product classes were omitted due to an inconsistency between the efficiency levels used to estimate manufacturer cost and the levels found in the retail price data. The Internet retail data for natural gas clothes dryers included only models significantly more efficient than the baseline efficiency of 2.67 lbs/kWh defined for this product class, and would thus not be appropriate for the estimation of a baseline markup. The NPD data set for room air conditioners reports efficiency in increments of 0.5 EER. Manufacturer production costs for less than 20,000 Btu/h units with louvered sides are reported for units with base efficiencies of 9.7 and 9.8 EER. These categories could not be satisfactorily matched to NPD retail price data.

a For the other product classes, there was an imperfect match between efficiency levels of retail data and those used to estimate manufacturing cost.
