About our calculations

All calculations use the standard formula: Energy (kWh) = Wattage ÷ 1,000 × Hours, then multiplied by your electricity rate. Wattage data comes from manufacturer specifications, Energy Star, and verified product listings. Electricity rates use official government averages (US EIA, UK Ofgem, Natural Resources Canada).
