Before you write
A quick reminder: our figures are estimates for guidance, not exact billing. Your real cost depends on your own electricity rate and how you actually use the appliance. For the most accurate result, enter the rate from your latest bill into any of our calculators, and have a look at our guides for help reading your bill.
