A worked example

Calculate household costs: electricity, appliances and budget

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.

Frequently asked questions

Are watts and kilowatt-hours the same?

No. Watts measure power. Kilowatt-hours measure energy used over time. Cost calculations need power, running time and an energy price.

Can the examples determine my tariff?

No. Example prices are illustrative inputs. Use your bills or contract and consider fixed charges, tariff tiers and changing usage.

Calculate appliance electricity costs: watts, kWh and annual cost

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.
