Electricity cost calculator

Our Electricity Running Cost Calculator is designed to work out how much it costs to run individual electrical items. The important rating you need is the Wattage which is usually written on the item somewhere. Complete the top boxes, and the results are shown in the lower boxes.

Now you’ve checked running costs, see how much you might save with a different energy tariff. Using this free service is much easier than collecting prices individually!
