How is electricity cost calculated?

To calculate how much a device or appliance costs to run, simply multiply the amount of energy used (kWh) by the unit cost of one kWh.

For example

If an oven uses 2000 watts of electricity, or 2 kW, and you use the oven for 2 hours, then you will have used 4kWh. If the unit cost of 1 kWh is 35p for example, multiply 35p by 4.

£0.35 x 4 = £1.40
