B. Economic Justification and Energy Savings 1. Economic Impacts on Individual Customers DOE analyzed the economic impacts on MHLF customers by looking at the effects that potential amended standards at each TSL would have on the LCC and PBP. These analyses are discussed in the following sections.
a. Life-Cycle Cost and Payback Period In general, higher-efficiency products affect consumers in two ways: 1
Purchase price increases and 2 annual operating costs decrease.28 Inputs used for calculating the LCC and PBP include total installed costs i.e., product price plus installation costs, and operating costs i.e., annual energy use, energy prices, energy price trends, and

replacement costs. The LCC calculation also uses product lifetime and a discount rate. Chapter 8 of the final determination TSD provides detailed information on the LCC and PBP
analyses.
Table V.2 through Table V.13 show the LCC and PBP results for the ELs and TSLs considered for each equipment class, with indoor and outdoor installations aggregated together using equipment shipments in the analysis period start year 2025. The results provided here will differ from the LCC
and PBP results from the NOPD due to updated data used for this final determination. Results for each equipment class are shown in two tables. In the first table, the simple payback is measured relative to the baseline product. For ELs having a higher first years operating cost than

that of the baseline, the payback period is Never, because the additional installed cost relative to the baseline is not recouped. In the second table, impacts are measured relative to the efficiency distribution in the no-newstandards case in the compliance year see section IV.F.8 of this document.
Because some customers purchase products with higher efficiency in the no-new-standards case, the average savings are less than the difference between the average LCC of the baseline product and the average LCC at each TSL. The savings refer only to customers who are affected by a standard at a given TSL. Those who already purchase equipment with efficiency at or above a given TSL are not affected. Customers for whom the LCC increases at a given TSL experience a net cost.

Note: The results for each EL are calculated assuming that all customers use equipment at that efficiency level. The PBP is measured relative to the baseline equipment.
