As we become increasingly aware of our carbon footprint and seek ways to reduce our energy bills, it can be handy to know how much energy our household appliances use. Whether that is by vampire appliances left on that slowly suck the energy from the system e.g. wifi routers, or high-usage appliances around the house that make our smart meters or home energy monitor come to life e.g. microwaves, tumble dryers, hair-dryer or external security lights, it's good to understand their impact on our home energy bills and help us to both use and spend less.
Below, we've developed a handy little electricity cost calculator to help you see how much each item costs to run monthly. In addition, we take this cost and run an energy price comparison to find you the best energy deal on the market and show how much you can save by switching suppliers.
To use the cost of running a house calculator, select the item from those listed or enter the wattage of your specific item. The relevant fields will automatically update as you move through the tool to calculate your kilowatt hours (kWh) and use this against your existing electricity price per kWh, resulting in an accurate view of the electricity costs associated with your chosen item.
| Watts (1 Kilowatt = 1000 Watts) | |
| Watts/1000 = Kilowatts or Kwh | |
| Hours Used | |
| Kilowatts x Total Hours = Kilowatt Hours (Kwh) | |
| Pence Per Kwh | |
| Kwh x Pence Per Kwh = Cost | |
| Number of items in home | |
| Total Cost | |
| Cost if you were on the cheapest electricity tariff in the market |
