80 PLUS payback

Certification floors come from CLEAResult 80 PLUS 115V internal requirements. These are certification floors at the named load points, not the efficiency curve of a particular unit. 80 PLUS Ruby exists in the current program and is not modeled here. Below the lowest published point, WattWise holds the nearest published efficiency instead of inventing a lower-load curve. Tiers in this tool: White (Standard), Bronze, Silver, Gold, Platinum, Titanium.

Electricity rate

EIA Electric Power Monthly, Table 5.6.A, average price of electricity to ultimate customers by end-use sector, residential column. August 2026, released 2026-10-23. 2026 values are preliminary. EIA does not publish a tariff. The figure is average revenue per kilowatthour from Form EIA-861M. It is not your utility's rate, and it is not a time-of-use price.

Enter a price difference to calculate payback. The table above does not need one.

Floors are the CLEAResult 115 V internal points. A real unit can be better. Below the lowest published point, the nearest published efficiency is held.
