Pick a power or type the watts from the appliance label:
The same use, a year, around the US
How it works: watts × hours ÷ 1,000 = kWh; kWh × price = cost. A year is 52 weeks of use. Default prices: US EIA residential averages (August 2026); UK Ofgem price cap (1 October to 31 December 2026, Direct Debit, without the daily standing charge). Use the price on your own bill for an exact figure. The label shows the maximum power; appliances with a thermostat or a cycle usually draw less on average.
