Numbers you can check

WattCost answers one question well: what does an appliance actually cost to run — your specific model, in your state. Every figure is computed from two public datasets (EPA ENERGY STAR certification data and US EIA electricity rates) with a formula you can reproduce yourself. No sponsored rankings, no manufacturer relationships, no estimates dressed up as measurements.

Founder and maintainer of WattCost. I built this site because most answers to “what does this appliance cost to run” are estimates with no sources behind them - so here, every figure is computed from public, certified data with a formula you can check against the datasets yourself.
