Open calculatorA worked example
An 800 W appliance uses 0.8 kW. Running three hours a day for 30 days consumes 72 kWh. At an entered price of €0.30/kWh, usage costs are €21.60; any fixed charge is separate.
No. Watts measure power. Kilowatt-hours measure energy used over time. Cost calculations need power, running time and an energy price.
No. Example prices are illustrative inputs. Use your bills or contract and consider fixed charges, tariff tiers and changing usage.
What does a lamp, PC or refrigerator cost to run each year? Separate power in watts from energy in kWh and use your own electricity tariff. Compare appliances over the same usage period rather than judging them by wattage alone.
