Appliance electricity usage calculator
Pick an appliance from the list or enter your own. Set the power rating, the days of the week and the running time — either plain hours or duty cycles (a fridge, for example: 10 min every 30 min). I work out the energy used and what it costs: on a working day, per month and per year.
Energy used—on a working day
Cost on a working day—
Monthly cost—on average
Yearly cost—
The result is an estimate. For appliances that run in cycles it uses their average power and running time over the day — not the peak rating from the nameplate.
