What does it cost to run your appliances?

How we work

How the numbers are worked out

Every figure here is arithmetic you can repeat yourself: wattage, hours of use, and your own rate per kilowatt-hour.

  • Where the numbers come fromWe start from an appliance's rated wattage or a typical figure for its class, apply the hours it actually runs, and price it at a stated rate per kilowatt-hour. These are calculations, not measurements of a specific unit.
  • Why the figures are illustrativeRates, runtimes and models vary, so worked examples are labelled as illustrative and name the price, wattage and rate they used. Change any input and the answer changes with it.
  • How we make moneyAt the time of writing this site carries no affiliate links and no advertising. No link earns a commission and no company pays for coverage. If that ever changes, the disclosure page will say so first and any paid link will be marked where it appears.
The defaults behind the figures

BenchNest covers the home appliances that quietly run up a power bill. The figures are calculated from wattage and hours, not measured, and each guide states the numbers it started from.

  • Wattage in, kilowatt-hours outRated or typical draw, multiplied by the hours the appliance actually runs.
  • Priced at your own rateExamples use a rate of $0.16 per kilowatt-hour unless a guide says otherwise. Yours is on your bill.
  • Assumptions written downHours, rate and any consumable cost appear next to the answer, so you can redo it.
