Regional proxy
ZIP code is used to place a household into a broad U.S. region. It is not used to identify an exact utility or tariff.
Methodology
How Energy Cost Check builds its estimates.
Energy Cost Check is an independent editorial guide for U.S. households. The site does not use live utility account data or real-time tariff feeds. It uses broad household logic to produce directional estimates and practical recommendations.
What The Model Uses
Inputs are simple on purpose.
Home profile
Square footage, occupancy, and heating type are used to move the estimate up or down within a realistic household range.
Usage framing
The homepage quick check uses home size and usage level to create a directional estimate rather than pretending to know exact consumption.
What It Does Not Use
There are deliberate limits to avoid fake precision.
No live tariff feeds
The site does not pull live supplier plans, utility account data, delivery charges, taxes, or promotional electricity offers.
No account matching
Users are not asked for account numbers, phone numbers, or billing logins to generate a result.
No guaranteed savings promises
Recommendations are framed as likely areas to investigate, not guaranteed dollar outcomes.
Source Direction
Public U.S. household energy references inform the framing.
EIA electricity use in homes
This source helps anchor how electricity use changes by U.S. region and by home type.
https://www.eia.gov/energyexplained/use-of-energy/electricity-use-in-homes.phpEIA energy use in homes
This source supports broader framing for residential energy use and the role electricity plays in U.S. homes.
https://www.eia.gov/energyexplained/use-of-energy/homes.phpDOE Energy Saver guidance
This source supports common household guidance around efficiency behavior, upgrades, and practical energy-saving actions.
https://www.energy.gov/energysaver/energy-saverEnergy Cost Check uses broad public-reference logic consistent with U.S. household energy information such as electricity price patterns, common residential usage behavior, and home efficiency guidance.
The site's goal is not to reproduce those datasets line by line. It is to translate them into a simpler consumer-facing estimate that avoids fake exactness.
