Electricity Cost Calculator

About Electricity Cost Calculator

An electricity cost calculator turns an appliance's power draw and how long it runs into what it actually costs you - per day, per month and per year. It is the quickest way to see whether an old fridge, a space heater or an always-on device is quietly running up your bill, and to judge whether replacing it pays off. Enter the wattage, the hours of use and your price per kilowatt-hour, and the running cost appears instantly. The value of costing an appliance is that it turns an abstract wattage into money you can act on. A space heater or an old second fridge can quietly add more to a yearly bill than people guess, and seeing the annual figure is often what finally justifies replacing it or switching it off at the wall. The calculator multiplies power by time by your tariff, which is exact for a device that draws steady power. Appliances that cycle - fridges, freezers, air conditioners - run their compressor only part of the time, so they cost less than their peak wattage suggests; use a lower effective hours figure for them. Tiered tariffs and standing charges live outside this simple per-kilowatt-hour view.
