About this site

What this site is
ApplianceEnergyCost.com answers a household question with actual math: what does this appliance cost to run? We maintain cost pages for 50 common appliances, localized to every state's electricity rate, plus 9 guides on the bill itself — written to separate the folklore (unplug your toaster) from the finance (fix your water heater setting).
The site is independent — no affiliation with any manufacturer or utility — and is supported by advertising.
Where the numbers come from
- Wattages are typical figures for modern appliances, stated as ranges where models vary widely, compiled from manufacturer specs and measured-usage surveys.
- Electricity rates are state average residential figures based on EIA data, refreshed periodically — and every calculator lets you enter your exact rate from your bill.
- Usage assumptions (hours per day, cycles per week) are stated on every page next to the result they produce.
How every figure is calculated
Cost = watts ÷ 1,000 × hours × rate (¢/kWh). That's the whole formula — the site's value is in honest wattage and usage inputs, localized rates, and doing the per-hour/day/month arithmetic for you.
Every figure is an estimate and labeled as one: your appliance's wattage, your usage pattern and your utility rate all vary. For appliances that cycle (fridges, ACs), we use effective average draw rather than nameplate peak — the number that actually shows up on a bill.
