This is a planning estimate, not a guarantee. Results vary. Eligibility, amounts, availability, and stacking are not guaranteed.

Method, sources & limitations

Geolocation runs only after you click. Coordinates go directly from your browser to the U.S. Census Geocoder. This site applies only the derived ZIP/state and sends the ZIP—not coordinates—to the U.S. EPA ENERGY STAR Rebate Finder. Calculator inputs are not stored, placed in URLs, or sent to Analytics.

The household choices use DOE 38-, 55-, and 84-gallon daily draw profiles as planning benchmarks. The HPWH estimate uses DOE’s ENERGY STAR reference UEF of 3.3 and a 67°F test temperature rise.

Electric-resistance comparisons use the selected state’s May 2026 year-to-date EIA residential average. Natural-gas and propane comparisons use national EIA averages. Utility prices are averages, not your tariff; results exclude installation, equipment cost, incentives, and financing.
