Understanding how much it costs to run your household appliances will help you to reduce your energy bill.

How to work out the amount of energy used

To calculate the amount of energy used by each appliance you need to take the power rating of the appliance in kW (1000W= 1kW) and multiply it by the number of hours used. This will give you the kWh.

Power rating in kW×hours used per day =kWh

How to calculate the energy cost of each appliance

In order to calculate the cost you need to multiply the kWh by the unit cost (you can find this on your energy bill).

kWh per day x unit cost = electricity cost per day
